1, health misunderstanding in summer
Misunderstanding of summer health: sweating a lot is good for health.
On the one hand, sweating in summer can evaporate and dissipate heat, keeping the body temperature constant; On the other hand, it can discharge a variety of harmful metabolic wastes, such as lactic acid, carbonic acid, creatinine, urea and bacterial toxins. Therefore, as long as you can sweat and urinate in summer, you won't get sick. If you have no sweat and less urine, it is often a precursor to summer sickness. The sweat glands of the elderly are atrophied, so they are prone to summer sickness.
So, why is sweating bad? The reason is that a small amount of sweating evaporation has the best heat dissipation effect; If sweat drips, its heat dissipation effect is not good, which will damage body fluid and vitality in vain. Because a lot of sweating will lose a lot of useful substances, resulting in insufficient potassium and sodium in the body. According to the determination, sweat also contains trace elements such as zinc, copper, chromium, molybdenum, cobalt and iodine, as well as active substances such as vitamins, so excessive sweating will lead to dehydration and weakness. In addition, a lot of sweating can concentrate blood and increase blood viscosity, which is dangerous for thrombosis and myocardial infarction induced by arteriosclerosis. Therefore, when you sweat a lot in hot summer, you should always replenish water and salt. Drink vegetable soup for three meals on weekdays and eat fruits and vegetables rich in water, vitamins and potassium salts, such as watermelon, cucumber, spinach and loofah.
Misunderstanding of summer health: drink more water after exercise
Exercise in summer is bound to sweat a lot. If you exercise for a little longer, your body will lose more water and you will inevitably feel thirsty. Some people drink a lot of water after exercise. First of all, they feel happy. Second, they think that drinking more water can supplement the body's needs and balance body fluids as soon as possible. In fact, this practice is wrong. When people are exercising, a lot of blood will remain in the muscles of their limbs. If you drink plenty of water immediately after exercise, some blood vessels in the gastrointestinal tract will contract sharply, and the absorption capacity will be weakened. People will feel heavy and swollen in the stomach, which will hinder the activity of the diaphragm and affect normal breathing. Therefore, after summer exercise, you should add some water, especially salt water, and don't drink a lot of water quickly.
Misunderstanding of summer health: shirtless and cool
In the sultry dog days, there are always people who like to go naked, thinking that it is cool, but it is not necessarily so. From a physiological point of view, human body temperature regulation depends not only on skin evaporation, but also on skin radiation. According to the measurement, in the environment with the temperature of 18-28 degrees Celsius, 70% of human body temperature depends on skin radiation, convection and conduction. When the temperature reaches 35 degrees Celsius, the body temperature mainly depends on skin evaporation to dissipate heat; When the temperature continues to rise, the skin can not only radiate heat, but also absorb heat from the external environment. Therefore, if you go shirtless at this time, it is easy to absorb heat. You will feel more sultry, not cool.
Misunderstanding of summer health 4: It is not advisable to stay up late in summer nights.
Some people think it's better to sleep after the temperature drops in the middle of the night in summer and get up again the next night. But according to the law of human biological clock, the best sleep time is 22-23 o'clock, and 5-6 o'clock in the morning is the climax of biological clock. At this time, the spirit of getting up is the best. So in summer, everyone still has to live on time.
Misunderstanding of health in summer: open doors and windows to cool down.
In hot summer, the outdoor temperature is very high, and sometimes even the wind outside is hot. At this time, opening doors and windows will make the indoor and outdoor temperatures as high. Therefore, if the outdoor temperature is very high in summer, the doors and windows should be closed before the highest temperature 14 to keep the indoor temperature at a low level, and then the doors and windows should be opened at night to make the room cooler.
2. How to maintain health in summer?
According to the theory of four-season health preservation in traditional Chinese medicine, summer belongs to fire, and fire leads to the heart, so summer is the most suitable season for nourishing the heart, and summer health preservation should focus on nourishing the heart. So how should you nourish your heart in summer? The heart and brain are closely linked. In China culture, there is a very interesting phenomenon, that is, all words that reflect people's thoughts and will activities are related to the heart-mood, desire, be elated, upset and uneasy. The heart here refers not only to the single organ of the heart, but also to the thinking of the brain.
Medically speaking, the heart and the brain belong to a system, and there are abundant nerves here, which are most easily influenced by the environment. Therefore, this is also the reason why people are easily upset when their heart health is threatened in summer. The so-called heart governs the gods, nourishing the heart and nourishing the brain are actually carried out at the same time.
Heart disease begins in summer. In the health culture of traditional Chinese medicine, the four seasons and five elements correspond to the five internal organs of the human body. This simple science is not unreasonable. Summer belongs to fire. After heart inflammation, people are prone to fatigue, chest tightness, poor sleep, headache, palpitation and other symptoms. After the heart burden increases, cardiovascular and cerebrovascular diseases are also prone to occur frequently. At the same time, spleen disease began in the long summer, and wet pathogens prevailed in the late summer, gastrointestinal function was inhibited, digestive ability and resistance decreased, intestinal bacteria multiplied in large numbers, and spleen and stomach discomfort often appeared.
3, summer nourishing cool raiders
Work and rest
Adequate sleep in summer is more important than anything else. A proper nap will quickly replenish the energy lost in the day, and regular work and rest can calm the mood. Night life is rich in summer, and staying up late seems to be a habit, but you should know that all these make daytime boredom worse.
sports
Summer exercise should not be too intense, and outdoor sports and ball games in the sun are even more exhausting, which is not a good idea. Summer exercise should be scientific, timely, moderate, moderate and timely. In order to avoid the harm of strong sunlight to the skin and body, it is best to arrange exercise time in the early morning or in the evening when the weather is cool, and try to avoid outdoor exercise from 10 to 4 pm.
appropriate
In summer, human consumption increases, sleep and appetite decrease, and body reserves are relatively weak. Therefore, we advocate relaxation exercise, the time is controlled at about 20 to 30 minutes, and the intensity is appropriately reduced. We can choose swimming, walking, jogging, Tai Chi and yoga. The right place. Try to exercise outdoors and choose cool and ventilated places such as parks, lakes and courtyards. Even if you exercise indoors, you should open the doors and windows properly to keep the air circulating.
Meridian massage
Traditional Chinese medicine meridian massage has been proved to be an effective health care method. Here, we recommend two simple and easy self-massage methods for nourishing the heart: 1. Pressing Dazhui at the depression under the spinous process of the seventh cervical vertebra at the lower end of the neck can clear away heat and damp; 2. Pressing the pericardium meridian in the middle line of the inner arm and the heart meridian of hand shaoyin at the outer edge of the inner arm every day can relieve diseases of cardiovascular system, nervous system and meridians such as heartache, palpitation and cardiothoracic boredom. In addition, pressing the simplest temples and Tang Yin points also has a refreshing effect.
There are many aspects of knowledge involved in summer health care, and some basic problems still need attention. For example, it is not appropriate to wash cold water just after sunbathing, and the sharp cooling of the body may easily lead to a cold and fever. Therefore, it is beneficial to maintain health in summer, and it is also beneficial to accumulate more health knowledge.
