Is hot weather suitable for fitness?

When the weather is hot, the metabolism of the human body is accelerated and the burden on the heart is heavier. According to the theory of traditional Chinese medicine, summer is the time when you need to nourish your heart most. The so-called nourishing the heart is not only the maintenance of the heart, but also the psychological conditioning. How to scientifically and reasonably raise the heart, today we will talk about this topic.

Cardiovascular diseases are prone to occur in summer.

The high temperature in summer will obviously increase the oxygen consumption of human myocardium compared with other seasons, and the heart often needs to be overloaded. In addition, sweating in summer makes people's blood viscosity higher, which increases the incidence of cardiovascular and cerebrovascular diseases. It is found that July and August each year is the peak period of acute myocardial infarction in patients with coronary heart disease, and the mortality rate is also relatively high. So the midsummer every year is the season to test the heart. According to the theory of traditional Chinese medicine, the seasons correspond to the five elements and five internal organs. Summer belongs to fire, and the corresponding viscera is "heart", so nourishing the heart has also become a focus of summer health care.

Toe tips increase the blood supply to the heart.

The weather is hot, so strenuous exercise is not recommended for fitness. Experts suggest that tiptoe is a feasible aerobic exercise. By strengthening the blood circulation of lower limbs, blood can not only supply enough oxygen to myocardium, but also be beneficial to human heart and cardiovascular health, exercise calf muscles and ankles, prevent varicose veins and enhance the stability of ankles.

The specific method is: put your feet together on the ground, lift your heels hard, then relax and repeat 30 times (or depending on your personal situation). When you stand on tiptoe, the blood volume squeezed out by each contraction of the muscles behind your legs is roughly equivalent to the blood volume discharged by each heart beat. You can do 1 tiptoe exercise every 1 hour, which is also a good exercise method for many elderly people with knee arthritis.

Heart-nourishing exercise is optional in Tai Ji Chuan.

Chinese medicine often says "nourishing Yang in spring and summer". In other words, even in hot summer, we should pay attention to protecting the yang in the body. Tai Ji Chuan's combination of dynamic and static, flexibility and rigidity, moderate opening and closing, ups and downs, impartial figure, vital qi in it, the unavoidable cold, combined with natural yin and yang, can be described as one of the best works of nourishing the heart in summer.

Many people think that Tai Ji Chuan's routines are complicated and difficult to learn. In fact, the routine is only a representative form, and the simple action of standing piles is quite particular. Eyes closed lightly, feet standing naturally, body straight, knees slightly bent, mind calm, upper deficiency and lower solid, feet taking root. Beginners can start with standing piles and then gradually learn simple movements. It is important to cooperate with breathing. Slow, deep, long and even breathing can not only eliminate anxiety, but also maintain the tiny blood vessels and meridians of the heart.

Stay calm and open-minded

The "heart" for nourishing the heart in summer does not completely refer to the concept of "heart" in modern medicine, but the whole nervous system of "God" including the heart, and even psychological factors. Too high a temperature can easily make people nervous and have mood swings. Therefore, summer health should be quiet.

As the saying goes, "peace of mind is naturally cool." As long as you keep your mind calm and open-minded, there will naturally be coolness coming out of your heart. When the mood is calm, people's sympathetic nerve excitability decreases, and the secretion of adrenaline and norepinephrine also decreases. As metabolism slows down, people's heart rate will slow down and their fever will be reduced. Clearing your mind and closing your eyes is conducive to the maintenance of your mind. Slow sports such as fishing and boxing are helpful to adjust your spirit and keep your mood comfortable. Feeling relieved can avoid arrhythmia and high blood pressure.

Pay attention to protect the heart in summer.

Ensure water supply and sweat more in summer. If we don't pay attention to replenish water in time, it will lead to the decrease of water in blood and the increase of blood viscosity, which will lead to slow blood flow and vascular embolism, which will easily lead to acute myocardial infarction and sudden cardiac death. Don't wait for dry mouth to drink water. Get into the habit of drinking a cup of cold water half an hour before going to bed, waking up in the middle of the night and getting up in the morning.

Ensure adequate sleep in summer, people often lack sleep, and the consumption of myocardial energy and oxygen increases, leading to the recurrence of heart disease. Therefore, it is necessary to develop the habit of taking a regular nap to make up for lack of sleep at night. It is advisable to rest for about half an hour at noon every day.

"Three and a half minutes" When patients with cardiovascular diseases get up, they should lie in bed for half a minute, slowly get up and sit for half a minute, then hang their legs on the edge of the bed for half a minute, and then go down to the ground to prevent the attack of acute myocardial infarction.

Avoid the "devil's time" in 24 hours a day. The peak time of acute myocardial infarction is from 6 am to 1 1, which is medically called "devil's time". Therefore, people with coronary heart disease should not do strenuous exercise in the morning.
