If you are more afraid of heat than the people around you, you should check your thyroid gland!

How hard is summer? Taking one more step outside is like being tortured. The sunscreen you applied is quickly washed away by sweat. Others are not hot, but you are sweating profusely...

Endocrinologists remind: If you are more afraid of heat than people around you, it is best to check your thyroid gland.

Hyperthyroidism makes you more sensitive to heat than others

The thyroid gland is the largest endocrine gland in the human body. It is responsible for synthesizing and secreting thyroid hormones in the human body, regulating human growth and development in many ways and maintaining metabolism.

The thyroid gland is called the "life gland of the human body" because thyroid hormones are hormones that maintain basic body activities and have varying degrees of impact on the functions of almost every organ system.

Hyperthyroidism is the full name of hyperthyroidism, which is caused by excessive secretion of thyroid hormones by the human body. Hyperthyroidism can increase the excitability of multiple systems such as the nervous system, circulation, and digestion, and cause hypermetabolism.

Hyperthyroidism patients with high energy metabolism have a higher basal body temperature than the average person, and the hot summer temperature adds insult to injury.

In addition to being afraid of heat, hyperthyroidism affects the cardiovascular system, digestive system, hematopoietic system, reproductive system, and nervous system, causing symptoms such as excessive sweating, irritability, hand tremors, palpitations, rapid heart rate, weight loss, increased appetite, insomnia, increased bowel movements or diarrhea. Most patients also have symptoms such as enlarged thyroid gland and exophthalmos.

Female patients may experience decreased menstruation or even amenorrhea, while male patients may experience decreased libido, impotence, and decreased sperm count.

It should be noted that if the body does not have enough thyroid hormone, it will cause hypothyroidism, also known as hypothyroidism.

Due to poor blood circulation and insufficient energy production, patients with hypothyroidism may experience abnormal fear of cold, no sweating, and low body temperature. However, due to the insidious onset and atypical symptoms of hypothyroidism, almost 98% of patients are unaware that they are ill.

8 types of people are more likely to be afraid of heat

In addition to patients with hyperthyroidism, the following types of people are also easily "defeated" by the summer heat, and may even become a "high-risk group for heat stroke", and need to pay special attention on hot days.

Drinking too little water

Insufficient water intake is not conducive to the body's sweating and heat dissipation. When the body is overheated, it is recommended to drink warm water. Be careful not to drink ice water, otherwise it will affect the gastrointestinal tract and blood vessel contraction.

Don't like sweating

People who are born with underdeveloped sweat glands or who use drugs that inhibit perspiration have an imbalance in the body's heat dissipation function and are more likely to be troubled by summer heat.

Taking cold medicine containing antihistamines will inhibit the parasympathetic nervous system, and sweating depends on the operation of the parasympathetic nervous system. Once it is inhibited, it will affect the sweating function.

Lack of sleep

Sweating requires good cardiopulmonary function, and the heart needs to pump enough blood. When you often stay up late or lack sleep, your cardiopulmonary function is usually poor, which will affect sweating.

Frequent diarrhea

Diarrhea can easily lead to dehydration due to excessive water loss, which can easily cause heatstroke.

obesity

Fat people have thick subcutaneous fat, which makes it more difficult for them to dissipate heat.

Strong competitive spirit

People who are under high pressure, have a compulsive personality, and are obsessed with winning are prone to "emotional heatstroke" in summer.

Vigorous exercise

Exercise accelerates the production of heat in the body. The more you exercise, the more heat you produce. In addition, people with large muscles produce more heat during exercise than the average person, and are also at high risk of heat stroke.

People with metabolic diseases, chronic diseases, poor cardiopulmonary function, and those who use amphetamines (psychotropic drugs) are also prone to being afraid of heat.

At old age

Due to aging, the circulatory function of the elderly declines, the sweat glands in the skin atrophy, and the body's heat dissipation is poor.

How do people who are afraid of heat spend the summer?

If you are afraid of the heat due to illness or bad habits, you need to seek medical attention and adjust your lifestyle. In addition, doing the following things will also help you cope with the heat in a healthy way.

Reduce going out

Try to reduce outdoor activities on hot days and avoid prolonged direct sunlight. If the elderly need to go out alone, they should bring water, towels and some first aid medicines.

Don't be greedy for coolness

The indoor air-conditioning temperature should not be too low, 26℃~28℃ is appropriate. Do not blow cold air directly. You can also adjust the air-conditioner to dehumidification mode to relieve the stuffy feeling. Do not sleep on stone benches or wet places when you are outside to avoid cold wind and body damage. Dry yourself in time after getting wet in the rain. Do not take cold showers. 37℃~39℃ water temperature is best for bathing.

Eat a light diet

In summer, the diet should be light and mild, with warm soup and seasonal fruits such as tomatoes and watermelons. People with weak spleen and stomach, especially the elderly, can eat chicken soup and mutton soup in moderation.

Adjust your mindset

People who are afraid of heat in summer should pay attention to regulating their spirits and try not to get angry. Stay calm and don't be anxious or upset. You can "cool down" your emotions through self-adjustment and keep yourself in a good mood.

Exercise properly

Doing moderate exercise and making your body sweat is beneficial for heat dissipation, but exercise should be moderate to avoid excessive heat and sweating.

For most people, the temperature is high and the humidity is high in summer, so it is recommended to choose swimming or relatively low-intensity and slow-paced sports, such as yoga, Tai Chi, walking, etc. People with underlying diseases need to follow the doctor's advice and do what they can.

Take a nap

In summer, the days are long and the nights are short. Many people get up early in the morning and go to bed late at night. You can take a "midday nap" at noon to relieve the fatigue caused by lack of sleep.

Rehydrate in small amounts and frequently

Do not drink a large amount of water (more than 500 ml) at one time. It is recommended to drink one or two glasses of water first, and then continue to drink after half an hour.

Heatstroke medicine

You can prepare Shi Di Shui, Huoxiang Zhengqi Shui (tablets), etc. at home. Both contain alcohol, and it is not recommended to take the two medicines at the same time.
