Understanding the Relationship Between Weather and Human Health
We live in a world that is constantly influenced by weather.
Every day, our bodies experience changes in temperature, humidity, wind, sunlight, and seasonal conditions. Whether we are walking outside, working in an office, sleeping at home, or traveling between different environments, weather is always part of our daily lives.
Most people think about weather mainly when deciding what to wear or whether to bring an umbrella.
However, in the Heshoutang Natural Health System (HNHS), weather is considered an important natural influence on human health.
The human body is part of nature. As the natural environment changes, our bodies must continually adapt.
Understanding weather can help us enjoy its benefits while reducing unnecessary exposure to uncomfortable or potentially harmful conditions.
The HNHS emphasizes a simple principle:
Human health is supported by living in harmony with the natural environment and its changing energies.
Weather itself is not necessarily harmful. Problems may arise when environmental conditions become excessive, when the body cannot adapt comfortably, or when daily habits are poorly matched to seasonal changes.
The Six Major Weather Influences
In the Heshoutang Natural Health System, weather is understood through six major natural influences:
-
Wind
-
Cold
-
Heat
-
Dampness
-
Dryness
-
Fire
These influences are closely related to the traditional Chinese understanding of natural environmental changes.
Each has its own characteristics, and each may affect the body differently.
Wind: Movement and Change
Wind is associated with movement, activity, and rapid change.
Within the HNHS framework, Wind is related to Fire Energy because of its active nature.
Traditional Wind-related patterns may involve changing symptoms, wandering discomfort, skin irritation, or abnormal movement.
Wind may also combine with Cold, Heat, Dampness, or Dryness.
Cold: Contraction and Restriction
Cold is associated with Water Energy.
It has contracting and restricting characteristics.
Within the HNHS framework, excessive Cold may suppress Fire Energy and contribute to traditional patterns involving stiffness, discomfort, or restricted Qi movement.
Heat: Excessive Warmth
Heat is associated with Fire Energy.
When excessive, it may consume Water Energy and disturb the balance between warming and cooling influences.
Traditional Heat-related patterns may involve sweating, thirst, irritability, or discomfort in hot environments.
Dampness: Heaviness and Accumulation
Dampness is associated with excessive moisture and the traditional concept of Water Energy.
It is characterized by heaviness, persistence, and accumulation.
Traditional Dampness-related patterns may involve sensations of heaviness, digestive discomfort, or stiffness.
Dryness: Loss of Moisture
Dryness is associated with insufficient moisture.
It may become more noticeable in dry climates, heated indoor environments, or during seasonal transitions.
Dry environmental conditions can contribute to dry skin, irritated eyes, or discomfort in the nose and throat.
Fire: Strong, Intense Heat
Fire represents a more intense form of heating influence in traditional theory.
Within the HNHS framework, excessive Fire may consume Water Energy and disturb internal balance.
Although Heat and Fire are closely related, traditional theory may distinguish them according to their intensity and manifestations.
The six weather influences are natural parts of our environment. The HNHS focuses on understanding their characteristics and maintaining balance rather than trying to eliminate them.
Natural Weather and Human-Made Weather
The original Heshoutang teaching divides weather influences into two major sources:
Natural Weather and Human-Made Weather.
This distinction is particularly important in modern life.
Natural Weather
Natural Weather comes from the environment.
Examples include:
-
Spring breezes
-
Summer heat
-
Autumn coolness
-
Winter cold
-
Rainy and humid conditions
-
Dry desert air
-
Strong winds
-
Sudden temperature changes
People have experienced these environmental influences throughout human history.
Traditional seasonal health practices developed partly from observing how daily life changes throughout the year.
Human-Made Weather
Human-Made Weather refers to environmental conditions created or controlled by human technology.
Examples include:
-
Air-conditioning systems
-
Heating systems
-
Refrigeration and chilling systems
-
Industrial cooling systems
-
Fans
-
Climate-controlled buildings
-
Cold storage rooms
-
Artificially heated indoor environments
Modern technology allows people to create indoor temperatures very different from the outdoor environment.
For example, during an extremely hot summer day, a person may spend nearly the entire day inside an air-conditioned building.
During winter, someone may remain in a heated room for long periods.
These systems provide important benefits, including protection from dangerous heat and cold.
However, they can also create abrupt temperature transitions, uncomfortable drafts, or overly dry indoor air.
In the HNHS framework, both natural and human-made environmental influences deserve attention.
How Human-Made Weather Changes Our Daily Environment
In the past, many people spent more time experiencing outdoor seasonal conditions.
Today, much of daily life takes place inside climate-controlled environments.
A person may move between:
-
An air-conditioned bedroom
-
An air-conditioned vehicle
-
An air-conditioned workplace
-
An air-conditioned shopping center
-
A temperature-controlled gym
-
A climate-controlled home
This lifestyle reduces exposure to extreme outdoor temperatures, which is often beneficial.
At the same time, it may reduce awareness of seasonal changes and create frequent transitions between warm and cool environments.
For example, someone living in a hot desert climate may experience outdoor temperatures above 100°F (38°C), followed by indoor temperatures around 70°F (21°C).
The body must adjust to these changes.
Within the HNHS framework, maintaining a comfortable relationship between internal body conditions and the surrounding environment is an important part of everyday wellness.
The goal is not to avoid air conditioning or heating.
Instead, it is to use these systems appropriately while avoiding unnecessary environmental discomfort.
The Human Body Should Follow the Rhythm of Nature
One of the most important ideas in the original Heshoutang article is that our daily schedule should reflect seasonal changes.
Nature follows cycles.
The sun rises and sets.
Days become longer or shorter.
Temperatures rise and fall.
Plants grow, mature, decline, and rest.
The Heshoutang Natural Health System emphasizes that human daily routines should also recognize these natural rhythms.
In traditional Chinese health philosophy, seasonal living is considered a way to support harmony between the human body and the environment.
The original Heshoutang recommendation is:
Spring and Summer: Sleep Later and Wake Earlier.
Autumn and Winter: Sleep Earlier and Wake Later.
These recommendations reflect the traditional relationship between seasonal activity and rest.
Spring and Summer: Sleep Later and Wake Earlier
Spring and summer are seasons of increasing activity.
Days become longer, sunlight becomes more abundant, and the natural environment becomes more active.
Plants grow, animals become active, and outdoor activity often increases.
Within the HNHS framework, spring and summer are associated with outward movement and the expansion of natural energy.
The original Heshoutang recommendation is:
Go to sleep around 11:00 PM and wake up around 5:00 AM during spring and summer.
This schedule is presented as a traditional example of aligning daily life with the longer daylight hours.
Why Spring and Summer Are Associated With Greater Activity
In traditional seasonal theory, spring represents awakening and growth.
Summer represents expansion, warmth, and peak activity.
The HNHS interprets these seasonal patterns as an opportunity for the body to maintain a more active daily rhythm.
Possible lifestyle practices include:
-
Spending appropriate time outdoors
-
Taking advantage of morning daylight
-
Maintaining regular physical activity
-
Eating according to seasonal needs
-
Staying adequately hydrated
-
Avoiding excessive exposure to summer heat
However, 11:00 PM to 5:00 AM provides only six hours of sleep, which is less than the recommended amount for most adults.
Modern sleep guidance generally recommends at least seven hours of sleep for adults, with many people needing seven to nine hours.
Therefore, the traditional principle of waking earlier in spring and summer should be adapted to provide adequate total sleep.
A person who wishes to wake at 5:00 AM may need to go to bed considerably earlier than 11:00 PM.
The important principle is maintaining a healthy rhythm, not sacrificing necessary sleep.
Autumn and Winter: Sleep Earlier and Wake Later
Autumn and winter represent a different natural rhythm.
Days become shorter, temperatures fall, and the natural environment gradually becomes quieter.
Plants reduce their growth, some animals become less active, and nature enters a period of conservation.
Within the HNHS framework, autumn and winter are associated with gathering, preservation, and rest.
The original Heshoutang recommendation is:
Go to sleep around 9:00 PM and wake up around 7:00 AM during autumn and winter.
This traditional schedule provides a longer opportunity for sleep and reflects the idea of adapting to shorter daylight hours.
Why Autumn and Winter Emphasize Rest
Traditional seasonal theory views autumn as a time of gathering and winter as a time of storage.
The HNHS associates these seasons with conserving energy and maintaining internal warmth.
Appropriate habits may include:
-
Maintaining a consistent sleep schedule
-
Allowing sufficient time for rest
-
Keeping the sleeping environment comfortable
-
Avoiding prolonged exposure to severe cold
-
Maintaining regular but appropriate physical activity
-
Receiving natural daylight when possible
The traditional 9:00 PM to 7:00 AM schedule offers ten hours in bed, but not every adult needs ten hours of sleep.
Individual sleep needs vary according to age, health, activity, and other factors.
The central principle is to maintain sufficient rest while recognizing seasonal changes.
Why Seasonal Sleep Rhythms Matter
The body has an internal biological clock, commonly known as the circadian rhythm.
This system helps regulate sleep, wakefulness, body temperature, hormone release, and other physiological processes.
Natural light is one of the most important environmental signals affecting circadian rhythms.
Morning light helps the body recognize the beginning of the day.
Evening darkness helps support the transition toward sleep.
The HNHS principle of following nature's rhythm can be understood alongside the modern importance of regular sleep and appropriate light exposure.
However, seasonal living does not require everyone to follow exactly the same clock times.
A practical approach is to:
-
Maintain a consistent sleep and wake schedule
-
Obtain sufficient total sleep
-
Seek appropriate morning daylight
-
Reduce disruptive light exposure before bedtime
-
Adjust daily routines to seasonal conditions when practical
Following nature should support the body's health rather than create sleep deprivation.
Avoiding Excessive and Uncomfortable Weather
The original Heshoutang article advises avoiding what it describes as “crazy weather.”
Within the HNHS framework, this means excessive or extreme environmental influences.
These may come from either nature or human-made systems.
Examples include:
-
Extreme summer heat
-
Severe winter cold
-
Strong, uncomfortable winds
-
Excessive humidity
-
Very dry air
-
Sudden temperature changes
-
Direct exposure to overly cold air-conditioning
-
Excessively hot indoor heating
-
Prolonged exposure to refrigeration or chilling environments
The body is capable of adapting to many environmental changes.
However, extreme conditions can create unnecessary physical stress.
The HNHS emphasizes maintaining a comfortable balance rather than exposing the body to extremes.
Summer Heat and the Importance of Sweating
Sweating is one of the body's most important temperature-regulation mechanisms.
When body temperature rises, sweat glands release fluid onto the skin.
As sweat evaporates, it helps remove heat from the body.
This process is especially important during hot weather and physical activity.
The original Heshoutang article emphasizes that people living in air-conditioned environments may have fewer opportunities to sweat during summer.
From the HNHS perspective, summer is naturally associated with Heat, Fire Energy, outward activity, and sweating.
The traditional theory considers appropriate sweating part of the body's seasonal response.
However, sweating must be understood correctly.
Sweat primarily supports temperature regulation. The liver and kidneys perform most of the body's metabolic waste processing and elimination.
There is no established medical evidence that people must sweat every day to prevent toxins from accumulating in the body.
The traditional emphasis on sweating can instead be applied through appropriate movement, seasonal activity, and healthy temperature regulation.
Should You Sweat Every Day During Summer?
The original Heshoutang teaching recommends creating opportunities to sweat at least once daily during summer.
This recommendation reflects the traditional view that summer is a season of active movement and outward expression.
A practical way to approach this idea is through suitable physical activity.
Examples may include:
-
Walking
-
Gardening
-
Gentle outdoor exercise
-
Cycling
-
Swimming
-
Appropriate indoor exercise
-
Other enjoyable physical activities
Some activities may produce noticeable sweating, while others may not.
The amount of sweat varies considerably between individuals.
It depends on temperature, humidity, exercise intensity, fitness, medications, and individual physiology.
Sweating heavily is not necessary to obtain the health benefits of exercise.
In extremely hot weather, especially in desert climates, deliberately trying to produce heavy sweating can increase the risk of dehydration, heat exhaustion, or heatstroke.
Therefore, the HNHS principle of maintaining summer activity should be practiced without forcing the body into unsafe heat exposure.
How Air Conditioning Affects Sweating
Air conditioning helps maintain comfortable indoor temperatures.
It can reduce the risk of dangerous heat exposure, especially during extreme summer weather.
Because cooler environments reduce the need for evaporative cooling, people may sweat less while indoors.
This is a normal physiological response.
The original Heshoutang teaching highlights the difference between natural summer conditions and modern climate-controlled lifestyles.
Within the HNHS framework, people are encouraged not to become completely disconnected from healthy daily movement and seasonal activity.
This does not mean avoiding air conditioning.
A balanced approach is to use air conditioning for comfort and safety while maintaining appropriate physical activity.
Exercise can take place indoors when outdoor temperatures are dangerous.
Sweating, Water Energy, and Fire Energy
In the Heshoutang Natural Health System, summer Heat is associated with Fire Energy.
Water Energy provides cooling, moisture, and nourishment.
Sweating can be understood within this traditional framework as part of the body's response to Heat.
When Fire Energy becomes excessive, the HNHS describes it as potentially consuming Water Energy.
Heavy sweating may also lead to significant fluid and electrolyte loss in physiological terms.
Therefore, appropriate hydration is important during hot weather and physical activity.
Signs that someone may need more fluids or medical attention include:
-
Unusual thirst
-
Dizziness
-
Weakness
-
Headache
-
Dark urine
-
Reduced urination
-
Excessive fatigue
Confusion, fainting, or other signs of serious heat illness require urgent medical evaluation.
The goal is not to maximize sweating.
It is to maintain a healthy balance between activity, temperature regulation, and hydration.
Why the Original Heshoutang Teaching Advises Waiting Before Showering
The original Heshoutang article recommends:
Do not take a shower until your sweating has stopped.
This advice reflects a traditional concern about exposing the body to sudden temperature changes immediately after heavy sweating.
Within the HNHS framework, a person who has been sweating heavily may be considered more sensitive to external Wind or Cold.
The traditional recommendation is to allow the body to settle before bathing.
A Practical Interpretation
After exercise or heavy sweating, it can be helpful to:
-
Reduce physical activity gradually.
-
Move to a comfortable environment.
-
Allow breathing and heart rate to return toward normal.
-
Drink fluids as appropriate.
-
Shower at a comfortable temperature.
However, there is no medical requirement to wait until sweating completely stops before taking a shower.
A comfortable shower is generally safe after exercise.
The main concern is avoiding excessively hot or cold water if it causes discomfort, dizziness, or abrupt temperature stress.
For someone who is overheated, cooling measures may be important and should not be delayed.
Wind Exposure After Sweating
In traditional Chinese health theory, sweating is associated with changes in the body's exterior and the opening of the pores.
The HNHS describes a person who is sweating as potentially more susceptible to uncomfortable external Wind and Cold.
For example, someone may finish exercising outdoors and then immediately enter a strongly air-conditioned room.
The sudden change in temperature may create a sensation of chill or muscle tightness.
Traditional HNHS care emphasizes avoiding prolonged exposure to uncomfortable cold drafts after sweating.
Practical measures include:
-
Drying excess sweat when appropriate
-
Changing out of wet clothing
-
Avoiding prolonged exposure to uncomfortable cold air
-
Maintaining a comfortable indoor temperature
-
Rehydrating after physical activity
Cold air or Wind itself does not cause influenza. Influenza is caused by influenza viruses.
However, uncomfortable drafts and temperature changes may affect perceived comfort and can aggravate certain symptoms in some individuals.
Why Sleeping Conditions Matter
Sleep is one of the most important periods of daily rest and recovery.
During sleep, the body continues regulating temperature, breathing, circulation, and other essential functions.
The original Heshoutang teaching emphasizes the importance of avoiding direct exposure to fans and air conditioning while sleeping.
Within the HNHS framework, the concern is that prolonged direct Wind or Cold may disturb the body's comfortable balance.
The original recommendation is:
Avoid allowing a fan or air-conditioning vent to blow directly onto your body throughout the night.
This advice is best understood as a traditional comfort and environmental-management recommendation.
Fans, Air Conditioning, and Sleep
Fans and air-conditioning systems can improve sleep comfort, particularly in hot climates.
A comfortably cool sleeping environment may support better sleep.
However, direct airflow may cause discomfort for some people.
Possible concerns include:
-
Feeling too cold
-
Dry eyes
-
Dry nose or throat
-
Discomfort from prolonged drafts
-
Sleep disruption due to uncomfortable temperature
-
Increased awareness of existing muscle stiffness
The HNHS recommends adjusting the sleeping environment according to individual comfort.
Practical options include:
-
Redirecting air vents away from the bed
-
Adjusting fan speed
-
Using a fan that circulates air indirectly
-
Maintaining a comfortable room temperature
-
Choosing suitable bedding
-
Avoiding excessively cold or dry indoor conditions
It is important to distinguish environmental discomfort from infectious disease.
Fans and air conditioning do not directly cause influenza or other viral infections.
These illnesses are caused by infectious agents, not by airflow alone.
Wind, Cold, and Muscle Discomfort
In traditional HNHS theory, Wind is associated with movement, while Cold is associated with contraction.
When Wind and Cold combine, the resulting traditional pattern may involve stiffness or discomfort.
The original Heshoutang article associates direct nighttime airflow with the possibility of Wind-related muscle problems.
Within traditional theory, this may be interpreted through the combined properties of Wind and Cold.
Possible discomforts include:
-
Neck stiffness
-
Shoulder tightness
-
Upper-back discomfort
-
Lower-back stiffness
-
Muscle tension
However, muscle pain can have many causes, including posture, overuse, injury, inflammation, and neurological conditions.
Direct airflow should not automatically be considered the cause.
Maintaining a comfortable sleeping environment may help reduce unnecessary discomfort, but persistent muscle symptoms deserve appropriate evaluation.
Artificial Heating and Dry Indoor Air
Human-made weather is not limited to air conditioning.
Heating systems also change the indoor environment.
During autumn and winter, heating may make indoor air feel dry.
Dry air can contribute to discomfort in the skin, eyes, nose, and throat.
In the HNHS framework, Dryness is one of the six major environmental influences.
When Dryness becomes excessive, it may disturb the body's comfortable moisture balance.
Practical measures may include:
-
Maintaining a comfortable indoor temperature
-
Monitoring indoor humidity
-
Drinking adequate fluids
-
Using appropriate skin moisturizers
-
Avoiding excessive indoor heating
-
Maintaining heating systems properly
Indoor humidity should remain at a comfortable level without encouraging mold growth.
The HNHS principle is to recognize that both heating and cooling systems create environmental conditions that influence everyday comfort.
Adapting to Weather in Different Climates
Different regions have different environmental characteristics.
A person living in a humid coastal region may experience different conditions from someone living in a dry desert.
Similarly, someone in a cold northern climate may face different seasonal challenges from someone in a hot southern region.
The HNHS emphasizes adapting daily habits to the actual environment.
Hot and Dry Climates
Important considerations may include:
-
Protection from extreme heat
-
Adequate hydration
-
Avoiding prolonged outdoor activity during dangerous temperatures
-
Managing dry indoor and outdoor air
-
Maintaining safe indoor cooling
Cold Climates
Important considerations may include:
-
Appropriate warm clothing
-
Protection from prolonged cold exposure
-
Comfortable indoor heating
-
Maintaining regular movement
-
Avoiding excessively dry indoor air
Humid Climates
Important considerations may include:
-
Managing indoor humidity
-
Maintaining ventilation
-
Preventing damp indoor conditions
-
Staying comfortable during hot, humid weather
Windy Environments
Important considerations may include:
-
Appropriate clothing
-
Eye and skin protection when needed
-
Reducing exposure to blowing dust
-
Maintaining comfortable indoor airflow
Weather-related wellness practices should always account for actual conditions and individual needs.
Weather and Individual Differences
Not everyone responds to environmental conditions in the same way.
Some people are more sensitive to Cold.
Others find Heat more uncomfortable.
Some experience dry skin during winter, while others notice discomfort during humid weather.
Within the HNHS framework, these differences are considered when evaluating a person's overall balance.
Traditional assessment may consider:
-
Sensitivity to Cold and Heat
-
Sweating patterns
-
Skin moisture and dryness
-
Digestive comfort
-
Muscle and joint discomfort
-
Sleep patterns
-
Energy and vitality
-
Seasonal changes in symptoms
However, symptoms that are severe, persistent, or unexplained may require medical evaluation rather than being attributed only to weather.
A Practical Seasonal Wellness Routine
The original Heshoutang teaching can be summarized as a practical seasonal approach.
During Spring
Recognize the increasing activity of nature.
Maintain regular movement, obtain appropriate daylight, and adapt to changing temperatures.
During Summer
Respect the influence of Heat.
Stay active when conditions are safe, maintain adequate hydration, and use cooling systems appropriately.
Sweating may occur naturally during activity, but it should not be forced as a detoxification method.
During Autumn
Recognize the transition toward cooler and drier conditions.
Maintain consistent sleep, adjust clothing, and protect against excessive dryness.
During Winter
Emphasize sufficient rest, comfortable warmth, and protection from severe Cold.
Continue appropriate physical activity while respecting weather conditions.
Throughout the Year
Maintain a comfortable indoor environment.
Avoid unnecessary extremes.
Pay attention to sleep, hydration, physical activity, and environmental comfort.
These habits reflect the HNHS principle of adapting to nature rather than resisting it.
The Importance of Balance Between Water Energy and Fire Energy
The Heshoutang Natural Health System emphasizes the relationship between Water Energy and Fire Energy.
Water Energy is associated with cooling, moisture, and nourishment.
Fire Energy is associated with warmth, movement, transformation, and vitality.
The six weather influences interact with these energies in different ways.
Cold and Dampness are closely associated with Water Energy.
Heat and Fire are closely associated with Fire Energy.
Wind is associated with Fire Energy because of its active and moving nature.
Dryness reflects a reduction in moisture.
When these influences become excessive, the HNHS describes them as potentially disturbing the body's balance.
The goal of seasonal wellness is not to eliminate natural weather influences.
It is to understand them and adapt appropriately.
The Heshoutang Natural Health Approach
At Heshoutang Natural Health, we believe that understanding the environment is an important part of understanding human wellness.
Weather is always around us.
It may come from nature through Wind, Cold, Heat, Dampness, Dryness, and Fire.
It may also be created by human technology through air conditioning, heating, refrigeration, and other climate-control systems.
The Heshoutang Natural Health System emphasizes that the human body should maintain harmony with the changing energies of nature.
The original Heshoutang teaching recommends adjusting sleep and wake times according to the seasons:
Spring and Summer: Traditionally, sleep later and wake earlier.
Autumn and Winter: Traditionally, sleep earlier and wake later.
These seasonal principles should be adapted to ensure adequate sleep and a consistent daily rhythm.
The HNHS also emphasizes appropriate summer activity, comfortable sweating, avoiding excessive environmental exposure, and paying attention to the effects of artificial heating and cooling.
After heavy sweating, allowing the body to cool down comfortably and maintaining hydration are sensible practices.
During sleep, adjusting fans and air conditioning to avoid uncomfortable direct drafts may support rest.
At the same time, air conditioning and heating are valuable technologies that can protect health during extreme temperatures.
The central HNHS principle is to understand the six weather influences, respect seasonal changes, and maintain balance between the body and its environment.
A healthy lifestyle does not require exposure to extreme weather or forced sweating.
Instead, it involves appropriate rest, physical activity, hydration, comfortable environmental conditions, and attention to individual needs.
