Sweat-soaked sheets in the middle of the night? Reminder: Don't think it's body heat, or 'early warning' of 4 diseases

The 48-year-old Ms. Wang has always had a strong body. On weekdays, she and her two sisters open a late-night snack stall.

However, in the past two months, Ms. Wang has been sweating profusely at night. When she fell asleep in the middle of the night, even the sheets were soaked .

It wasn't until two weeks later that she found a lump on her neck that would slide. Finally, under the persuasion of a friend, Ms. Wang went to the local hospital for treatment, but she was unexpectedly prompted to be thyroid cancer.

In this regard, the doctor said that Ms. Wang's previous profuse sweating was not an ordinary weakness and heat, but a symptom caused by thyroid cancer.

1. If you sweat a lot in summer, is your body detoxifying?

Many people think that sweating is a manifestation of body detoxification, and even in pursuit of the detoxification effect, they will deliberately do some sweaty activities, such as exercise or sauna. Does sweating really mean that the body is detoxifying? Are people who sweat more physically healthier?

First, let's understand why the next person sweats?

Humans are warm-blooded animals, and their normal body temperature is generally maintained at around 37°C. In order to maintain a constant temperature, they need to sweat to dissipate excess heat . This perspiration process is controlled by the thermoregulatory center in the nervous system, which keeps the body's energy production and heat dissipation in balance.

Is sweating a detox? Many people want to sweat to expel excess heat and toxins from the body, so as to achieve the purpose of losing weight and maintaining health. But in fact, sweating has nothing to do with detoxification .

Sweat is the liquid secreted by sweat glands. 99% of sweat is water, and only a small part is urea, lactic acid, sodium chloride, etc. The toxins in the human body refer to the "wastes" that are of no value to human health, generally filtered by the liver and kidneys, and excreted from urine or sweat.

But the human body does not have so many toxins. Generally, the amount of "toxins" excreted in one urination is more than that in two days of sweating .

So, compared to people who sweat a lot or people who sweat less, which one is healthier?

Generally speaking, when working while sitting, adults sweat about 300 grams a day, but if they are nervous, or exercise or work outdoors, the amount of sweat will fluctuate by 1-10 times.

The amount of sweating of each person mainly depends on the reaction of the body's sweat glands to the sympathetic nerve activity. It is not only affected by the environment, but also related to genes, personal constitution, diet and other conditions . For example, men are more likely to sweat than women, heavier people are more likely to sweat than those who are underweight, and they are more likely to sweat after eating spicy food.

Sweating is a physiological phenomenon in which the body regulates body temperature, but if sweating too much or too little, it may be caused by certain diseases and needs to be treated in time, such as:

Hyperhidrosis

The patient presented with no other reason, and the whole body or parts (face, limbs, armpits) sweated profusely, and the clothes and shoes were soaked, which seriously affected daily life.

hypohidrosis

Contrary to hyperhidrosis, patients sweat rarely or not, have hot flashes, and are accompanied by symptoms such as dizziness, muscle cramps, and weakness.

2. Sweating while sleeping is not necessarily body heat, be alert to 4 kinds of diseases

Excessive sweating while sleeping, a condition commonly referred to as night sweats. Some people will simply think that this condition is caused by physical weakness or body heat, but in fact, night sweats may also be an early warning of disease.

Night sweats, also known as night sweats, are very common.

A related study found that 41% of people have night sweats. The vast majority of night sweats have nothing to do with physical weakness. As long as you don't sweat too much and affect your life, you don't have to worry about it, let alone taking medicine indiscriminately.

Whether it is night sweats, first of all, it is necessary to rule out whether the room temperature is too high, causing sweating. This situation is not considered night sweats. The real night sweats are redness, heat, and even sweating profusely when the skin is not so hot at night .

Sweating while sleeping is not necessarily a sign of weakness, and you should be careful about the possibility of illness.

1. Low blood sugar

People with low blood sugar are often prone to hunger, dizziness, sweating in summer, heart palpitations, unprovoked tension, anxiety, etc.

2. Hyperthyroidism

The most typical symptoms of patients with hyperthyroidism are heat intolerance and excessive sweating. Patients will have increased sweating during the day, accompanied by increased appetite, weight loss, and increased stool frequency.

3. Lymphoma

Many tumors can present with fever, sweating, and lymphoma is one of them. Patients will have systemic manifestations such as low-grade fever, night sweats, pruritus, and weight loss.

4. Menopause syndrome

Menstrual disorders, hot flashes, night sweats, and mood swings are typical early symptoms of female menopause, and urogenital tract inflammation may also occur in the long run.

If people who suffer from night sweats at night, if they want to reduce the symptoms of night sweats except for disease factors, try to adjust their daily diet, eat less spicy, fried and grilled foods, and eat more yin nourishing foods such as lily, tremella, and wolfberry .

In addition, proper physical exercise, such as jogging, Tai Chi, yoga, etc., can effectively prevent and improve night sweats.

3. After sweating in summer, doing 3 things will make you healthier

In summer, sweating is very common. When many people sweat, they either drink iced drinks or blow on the air conditioner. These actions are especially harmful. After sweating, what can you do to make your body healthier?

1. Don’t take a cold shower after sweating

After sweating, take a cold shower immediately. Contact with cold water on the skin will cause the capillaries to suddenly shrink and thin, and a large amount of blood will flow back to the heart, which will increase the load on the heart and may cause symptoms such as palpitation, shortness of breath, and dizziness.

Therefore, after sweating, wait for your body to return to normal body temperature before taking a shower.

2. Wipe sweat with a towel

When there is a lot of sweat, wipe the body with a dry towel first, at this time the pores of the body open quickly, which is conducive to better heat dissipation. Do not wipe with a cold towel, the skin is stimulated by cold, the pores shrink, and it is not conducive to perspiration.

3. Supplementary nutrition

After sweating, it is necessary to supplement vitamin C in time, such as lemon, sour jujube, strawberry, etc., which can play a role in collecting sweat and promoting body fluid.

When sweating, the body will also lose potassium, sodium and other elements. In summer, you can eat more soy products, bananas, apples, green vegetables, etc. to replenish the nutrients your body needs in time.

In addition, loss of appetite is also prone to occur in summer, resulting in the lack and loss of vitamin B family. Therefore, you should also pay attention to supplementing vitamin B family in summer. Mung bean soup, oatmeal, or animal liver are all good choices.

Sweating is a natural physiological phenomenon, but if you sweat for no reason, or if you sweat a lot at night, you should be alert and consult a doctor as soon as possible to find out whether it is caused by a disease.
