How to cool down at 39 degrees without air conditioning?
Hehe, shoot the breeze and get to the point.
39℃- Sweat glands are on the verge of failure, and the temperature is three-level alarm. Sweat glands are tired of work, powerless and prone to failure. At this time, it is easy to have a heart attack.
Good heatstroke prevention and cooling products
Salty water:
Traditional Chinese medicine calls boiled water "the king of all medicines". Drinking boiled water should choose fresh cold boiled water (20℃ to 25℃) that is naturally cooled after boiling. This kind of boiled water has specific biological activity, and it is easy to enter cells through the cell membrane and be quickly absorbed and utilized. You'd better add some salt when drinking boiled water. In summer, the temperature is high, sweating is much, the salt in the body is reduced, and the osmotic pressure in the body will lose stability, leading to heatstroke. Drinking salty boiled water or salty tea can supplement the salt lost in the body, thus achieving the effect of heatstroke prevention and cooling.
tea boiled water
Potassium is an important trace element in human body, which can maintain the normal function of nerves and muscles, especially the normal movement of myocardium. Scientific analysis shows that tea contains more potassium, accounting for about 1.5% of its proportion. Potassium is easily excreted with sweat, so tea with suitable temperature should be the first choice in summer.
In summer, the sun is like fire, the heat is scorching, sweating and thirsty. Drinking hot tea is the best way to prevent heatstroke and cool down. The advantages of drinking hot tea are:
1 can refresh the mind and eliminate fatigue.
2, can produce saliva to quench thirst. Drinking hot tea can stimulate oral mucosa, promote oral fluid production, accelerate the contraction of gastric wall, promote the opening of gastric pylorus, make water flow into small intestine and be absorbed by human body, and meet the needs of various tissues and organs.
3, it can inhibit bacteria and diminish inflammation. Tea has astringent and bactericidal effects on gastrointestinal mucosa, can coagulate bacterial proteins, reduce the toxicity of bacteria, and play the role of diminishing inflammation and quenching thirst.
4, can strengthen the heart and diuresis. Theophylline can excite vascular center, enhance heart and kidney function, promote blood circulation, enhance glomerular filtration rate and increase urine output. The discharge of urine takes away some heat and brings a cool feeling. Vinegar: In summer, people drink more water, so their stomach acid decreases correspondingly and their appetite decreases. Proper vinegar can increase the concentration of gastric acid, stimulate appetite and help digestion. Adding vinegar when cooking can increase stomach acid and increase appetite. Summer is the epidemic season of intestinal infectious diseases, and jealousy can also improve the bactericidal effect of gastrointestinal tract. In addition, if you add a few drops of vinegar during cooking, it will also reduce the loss of vitamin C in vegetables and help people absorb iron in food.
mung bean soup
Mung bean soup has a unique effect of relieving summer heat. Chinese medicine believes that mung bean has the effects of relieving summer heat and benefiting qi, clearing away heat and toxic materials, moistening throat and quenching thirst, and inducing diuresis to reduce swelling, which can prevent heatstroke. Related experiments show that mung beans have obvious effects on lowering cholesterol in blood and protecting liver. The only drawback is that mung beans are too cold to be eaten by the weak.
bitter gourd
Bitter gourd is fragrant and delicious because of its bitter taste, and it is regarded as a rare dietotherapy product. China folks have had the experience of "bitter can clear away heat" and "bitter can strengthen the stomach" since ancient times. Chinese medicine believes that bitter gourd tastes bitter and cold, and can clear away heat and purge fire. Bitter taste of bitter gourd can stimulate the secretion of saliva and gastric juice, increase appetite, clear away heat and prevent heatstroke, so it is appropriate to eat bitter gourd in summer.

Six misunderstandings of heatstroke prevention and cooling
First, over-reliance on air conditioning
After all, air conditioning is not a natural state. It can make the air flow and vibrate frequently, and the result is just like noise, which will damage people's nervous function. In addition, indoor air is recycled, and after repeated filtration, the negative ions in the air are obviously reduced, and there are too many cations, which affects the normal physiological activities of the human body. Living in an air-conditioned room for a long time will make people feel headache, dizziness, insomnia, gastrointestinal discomfort, fatigue, even cold-like symptoms, and even reduce their anti-infection ability. This is "air conditioning disease". Low temperature is most likely to cause autonomic nervous disorder in women, and women are particularly prone to "air conditioning disease". To prevent "air conditioning disease", negative ion generator can be equipped indoors to make up for the shortage of air conditioning; It is best not to use it if the weather is not too hot; The use time should not be too long, and it is not appropriate to sleep all night; Don't adjust the indoor temperature too low, so as not to be too different from the outdoor temperature; The room should be kept clean and hygienic, and smoking is prohibited indoors.
Second, the electric fan blows directly on the human body.
Some people like to enjoy the cool air, and often blow directly at the electric fan, which will cause a series of symptoms such as sneezing, runny nose, fatigue, headache, dizziness, insomnia, shoulder pain, loss of appetite and so on. This is called "Fan Disease". The key to prevent "fan disease" lies in the scientific use of electric fans. First of all, the rotation speed should not be too fast and the service time should not be too long, and it is appropriate to reach 1 hour in 30 minutes; Secondly, it is not advisable to blow the human body directly or too close. After blowing for a period of time, change the position of the fan or human body to avoid local cold for too long. Third, don't sleep with the fan on. When the temperature is too high, you can only use the breeze that shakes your head to control it regularly. When you sweat a lot, don't sit still and blow. In addition, the elderly and infirm, children and patients with chronic diseases, colds and arthritis should use it less or not.
Third, wash your feet with cold water to cool down.
Some people like to wash their feet with cold water, which is not desirable. Because people's feet are the distal parts of blood vessel branches, the skin temperature of the soles of the feet is the lowest in the whole body, and it is easy to catch cold; Furthermore, the fat layer of the feet is thin and the heat preservation is poor. If you often wash your feet with cold water, you will get cold further, which will cause a series of pathologies throughout the body through vascular conduction and eventually lead to various diseases. In addition, due to the well-developed sweat glands on the soles of the feet, the feet suddenly catch cold, which will suddenly close the pores, which will cause perspiration dysfunction after a long time. Especially after the sensory nerve endings on the feet are stimulated by cold water, the normal vascular tissues contract violently, which will lead to diastolic dysfunction for a long time and induce limb arteriolar spasm, erythematous limb pain, arthritis, rheumatism and so on.
Fourth, take a cold bath when sweating.
The temperature is high in summer, and the body generates more heat during exercise. It is an important way to dissipate heat through sweat and skin blood vessels. At the end of labor or exercise, the human body is still in a state of vigorous metabolism, increased heat production and vasodilation of the skin. At this time, if you take a cold bath immediately, the skin will be stimulated by cold, and the skin blood vessels will contract through nerve reflex. As a result, the body heat will be blocked and the body temperature will rise instead. At the same time, the decrease of skin blood flow suddenly increases the blood flow back to the heart, which will increase the burden on the heart. When the body changes from hot environment to cold environment, it is too late to adapt and adjust, and it is easy to catch a cold or cause gastrointestinal spasm. Muscle fatigue and tension increase after exercise, and then cold stimulation may also cause cramps. When sweating during work or exercise in summer, you should drink salt and boiled water properly, do some preparatory activities after a break of 1 hour, and then take a cold bath. If conditions permit, it is best to take a warm bath.
Five, swimming with illness
Some patients also like swimming in summer, but swimming is not suitable for everyone. The following patients are not suitable for swimming: patients with severe hypertension, whose blood pressure is still 23 after taking the medicine. 4/ 14。 Above 3 kPa, there are serious symptoms and the possibility of cerebrovascular accident; Patients with coronary heart disease who have suffered from angina pectoris recently and feel chest discomfort with a little exercise; Patients with valvular heart disease and heart disease with the possibility of heart failure; Mental patients and epileptic patients. These people are absolutely forbidden to swim in case of accidents in the water.
Six, gluttony frozen watermelon
Eating watermelons that have been refrigerated for a long time is harmful to human health. Because when eating frozen watermelon, the salivary glands, tongue taste nerves and periodontal nerves in the mouth will be paralyzed by cold stimulation, which makes it difficult for people to taste the sweetness of watermelon and hurt the spleen and stomach. Children's digestive ability is poor, and eating frozen watermelons can also cause anorexia, vomiting, diarrhea and other symptoms.
