1, what are the misunderstandings of summer health care?
1, the hotter the weather, the less clothes you wear.
Generally speaking, the smaller the clothing coverage area in summer, the faster the body dissipates heat, so the cooler it feels. But we can't generalize and think that "it's best to go shirtless in midsummer." Studies have shown that bare skin can only increase the radiation and heat dissipation of the skin when the skin temperature is higher than the ambient temperature, and the highest temperature in summer and hot summer is generally close to or higher than 37℃. The skin will not dissipate heat, but will absorb the heat of the external environment, so it will feel hotter if it is shirtless. In this sense, men should not go shirtless when the heat is unbearable.
The earlier you do morning exercises in summer, the better.
Because of the hot weather in summer, many people think that the earlier the morning exercise, the better. In fact, before dawn or when the sky is hazy, the temperature is really low, but the air may not be fresh. In fact, according to experts' research, air pollutants are the most difficult to diffuse before 6 am in summer, which is often the peak period of pollution. People generally like to do morning exercises in lawns, Woods, flowers and other places where green plants grow. Before sunrise, because there was no photosynthesis, there was not much fresh oxygen near the green plants, but a lot of carbon dioxide was accumulated, which was obviously harmful to human health. In addition, exercise in the morning is easy to catch a "common cold", easy to catch a cold, and easy to cause joint pain, stomach diseases and other diseases. Therefore, the morning exercise in summer should not be earlier than six o'clock.
3. The air conditioner should be kept at a constant temperature.
When many people use air conditioners in summer, they always set the temperature at a certain value and try to keep the room at a constant temperature or quasi-constant temperature. In fact, medical meteorologists have found through experiments that constantly adjusting the room temperature can make people's physiological body temperature regulation mechanism constantly in a "tense state", thus gradually adapting to temperature changes, improving people's self-protection ability and avoiding frequent colds or other room diseases. In this sense, air conditioning is also a health care product. Of course, when air conditioning is used for this adjustment, the temperature alternation range of the whole room should be controlled between 3 ~ 5℃; After half a month, the amplitude can be gradually increased to 6 ~ 65438 00℃. The temperature change should not be too sudden, but should be increased or decreased steadily (1 ~ 2℃ is appropriate for each adjustment).
2. Health precautions in summer
Go to bed late at lunch break and get up early.
In summer, people get up early because of dawn and go to bed late at night, which is easy to cause lack of sleep, so they should take more naps. The nap time varies from person to person, usually from half an hour to 1 hour. If you can't take a nap, listen to music or close your eyes for 30 to 50 minutes at noon.
Irritability is often associated with the heart.
Chinese medicine believes that the heart corresponds to summer, and the heart yang is the most vigorous in summer, so people are prone to irritability and temper tantrums. Therefore, we should pay special attention to the maintenance of the heart in summer, drink more milk and eat more soy products, chicken and lean meat. Usually eat more vegetables, fruits and coarse grains; Keep a good mood.
Eating more and eating less is good for nourishing.
Eating more and less is an important way to keep fit in summer, such as porridge for breakfast and dinner and soup for lunch. Add lotus leaves when cooking porridge, which has the functions of dispelling summer heat, nourishing stomach and clearing intestines, promoting fluid production and quenching thirst; Adding some mung beans to porridge or cooking soup with mung beans alone can relieve summer heat, quench thirst, clear away heat and detoxify, and promote fluid production and diuresis.
Don't forget potassium when supplementing nutrition.
Usually pay attention to supplement some nutrients, such as tomatoes, green peppers, wax gourd, bayberry, wax gourd, plums and other fresh fruits and vegetables; Supplement water and inorganic salts, especially potassium, such as beans and their products, mushrooms, etc. Eat more foods that can clear away heat and promote diuresis, such as watermelon, bitter gourd, peach, dark plum, strawberry and cucumber. Protein should be supplemented appropriately, such as fish, lean meat and eggs.
Choose fruits according to your physique.
For people with bad stomach, it is best to choose milder fruit, not too sweet or too sour. Patients with deficiency-cold constitution, stomach cold and gastric ulcer should eat less cold foods such as watermelon and cantaloupe.
Take the food out of the refrigerator and don't eat it.
After the gastrointestinal tract is stimulated by intense hypothermia, it is easy to cause physiological dysfunction. The temperature of human stomach is generally around 36℃, while the food just taken out of the refrigerator is only 2℃ ~ 8℃. It's best to put it for a while before eating, and don't eat too much at once, especially for the elderly, children and people with chronic gastritis and indigestion.
