Women must be careful to prevent heat stroke during summer passion

"Summer is the best time to practice yoga." Chen Li, a senior coach at Guangzhou Li Meijian Women's Yoga Studio, said that the body's qi and blood are more unobstructed in summer, so practicing is not only much easier, but the body will also become more relaxed and comfortable after fully stretching. Especially for many elderly people, whose arthritis is often more severe in winter and relieved in summer, they should seize this opportunity to practice yoga and do some auxiliary exercises for the damaged joints, which will help expel cold, blood stasis and dampness from the body. "I have a student who is 76 years old. Since she started practicing yoga, not only has her joints improved a lot, but her high blood pressure and high blood lipids have also improved. The doctor also recommended that she stick to it."

However, the biggest benefit of practicing yoga in this hot and humid season is that it can calm your irritable mood. Chen Li said that student Ms. Zhang had been suffering from insomnia for a long time and her personality became sensitive and anxious, but on the night of her first yoga experience, she slept very soundly for the first time ever. The next day, when her husband told her, "You slept as sweetly as a little girl," she signed up for an annual membership card without hesitation. "Yoga will become a part of my life for the rest of my life."

Sweating does not mean losing fat, be careful of heat stroke if the temperature is too high

"Practicing yoga in high temperatures will make you sweat a lot, but sweating does not mean that fat will burn. At present, there is no authoritative medical evidence to prove that hot yoga can help the human body lose weight." Associate Professor Chen Xiuhua, deputy director of the Traditional Therapy Center of Guangdong Provincial Hospital of Traditional Chinese Medicine, said: Practitioners of "hot yoga" for the purpose of losing weight and slimming down generally have misunderstandings about this fitness program. In fact, most of the weight lost is water. In the hot summer, it is particularly important to replenish lost water after exercise.

Professor Luo Xinghua from the Department of Sports and Health at Guangzhou Sport Institute pointed out that doing yoga in an environment with a temperature of 38-42 degrees Celsius, which is too high, will have a certain impact on the body temperature center. It will not only hinder the normal operation of the heat dissipation system, but also cause a large loss of body fluids and electrolytes due to the high temperature, which is likely to cause cramps, heat stroke and other conditions. "If you don't pay attention to ventilation and replenish the necessary water in time, it will lead to dehydration and physiological system disorders, and in severe cases it may even shorten your life. This goes against the original intention of practicing yoga, which is to strengthen your body and enhance your immunity."

Artificial temperature control is inappropriate, cool and ventilated is the most ideal

Since practicing hot yoga is somewhat dangerous, is it appropriate to control the temperature of the practice room within the human comfort range of 24-27 degrees Celsius? Professor Luo Xinghua said that as a result, the temperature difference between indoors and outdoors is large. Although people will feel comfortable when exercising indoors, it will hinder the sweat glands of the human body from secreting sweat and dissipating heat energy. The heat dissipation conduction system will slow down, which will have a certain impact on the human body. On the contrary, if you do yoga in an environment where there is not much temperature difference between indoors and outdoors, it will not have much impact on the body's functional loss as long as the amount of exercise is not excessive and water is replenished in time and adequately. "Of course, the ideal practice environment should be in a cool and ventilated place."

Things to note when practicing yoga in summer

In addition, Deputy Director Chen Xiuhua also put forward several points to note when practicing yoga in summer :

Practitioners cannot practice when they are too hungry or too full;

You don’t need to drink too much water before exercise. Instead, you should replenish water or salt (such as 0.9% saline) immediately after sweating.

The practice time should be determined according to individual physical condition. Generally, about 30 minutes is appropriate for beginners. Avoid excessive or even overload practice.

If you feel chest tightness, palpitations, shortness of breath, headaches, or other discomfort during the exercise, you should stop the exercise immediately and rest in a place with fresh air, good ventilation, or normal room temperature. If rest does not relieve the symptoms or the symptoms are severe, you should seek medical attention in time.

After exercise, the human body may suffer from temporary brain hypoxia due to fluid loss or high temperature environment. Avoid taking cold showers, turning on air conditioners or drinking cold drinks immediately. Take a hot shower only after a short rest and replenishing water. Do not turn on the air conditioner immediately after exercise for the sake of momentary pleasure or blow directly into the air outlet of the air conditioner.
