Why is it not suitable for running and fitness on hot days?

On hot days, the air is stuffy, the humidity is high, the air inhaled during running is hot, and the heart is stuffy, resulting in breathlessness, so that the rhythm is chaotic and it is difficult to run.

Running in high temperatures does affect the physical sensation, which can lead to physical exhaustion and collapse, and severe dehydration and heat stroke. In addition, due to the significant increase in sweating during running at high temperatures, electrolytes are also lost, which may lead to dehydration and electrolyte imbalances in the body. Therefore, hot days are not suitable for running health.

Running in hot weather is not good for your body.

Note 1: Avoid hot periods of the day, especially outdoor sports. If you're going to run out on a hot day, you have to avoid the hot hours of the day, which are usually from 10 a.m. to 3 p.m.

Generally speaking, when the temperature of the human body is lower than 33 degrees Celsius, sweating during exercise can achieve the effect of rapid heat dissipation. However, if the temperature exceeds 33 degrees, it will be difficult to dissipate heat, which may cause symptoms of heat stroke such as chest tightness, dizziness, thirst, nausea, etc. Of course, the ability to exercise will also decrease.

Note 2: Replenish water in time, in small amounts and many times. Sweating a lot while exercising, especially in the summer, can make you thirstier even more, so it's worth adding hydration. However, the rule of thumb is to "drink small amounts of water multiple times", i.e. hydrate before, during, and after your workout.

The main reason is that the high level of heat stroke is high, and if you exercise, the heat of the body will not be lost, which can easily cause heat stroke, so it is not suitable for running exercise.

On hot days, as the name suggests, the weather is hot, and in this case, running will exacerbate the loss of water in the body, which may lead to heat stroke.

Because running in hot weather is not conducive to heat loss, it is not suitable for fitness in hot weather. Thank you, ......

Because the weather is too hot can lead to a lack of water in the body

You can go to a professional gym, and don't run in the open air on hot days for fear of heat stroke! Drink plenty of water during summer exercise!

Excessive sweating for a short period of time will cause dehydration, and there will be heat who suffers.

Ladies and gentlemen, have you been running, fitness, running, fitness, athletics, the body of the gods can really increase height, if the piano is moved, it is easy to cause sudden death.

Outdoor exercise is not recommended when the temperature is below -9 degrees.

At this time, if you are still running outdoors, it will lead to slowing down of blood circulation and body metabolism, which will not only fail to achieve the desired exercise effect, but also may cause frostbite, muscle sprains, gas forks, cramps and other problems due to cold.

Many exercise experts also do not recommend running in winter mornings, also because the temperature in winter mornings is low, and a series of problems are prone to occur, and the gains outweigh the losses.

Too high humidity is not suitable for running

Humidity reflects how dry the air is, and its effects on the human body are directly reflected in perspiration, body heat dissipation, and water and salt metabolism.

When the air humidity is too high, the pineal gland in the human body secretes a large amount of pineal hormone, which makes the concentration of thyroxine and adrenaline in the human body relatively reduced, and the cells will produce "inert", and the external manifestations are listless, malaise, troubled and depressed. Obviously, such negativity is not suitable for running.

The humidity corresponding to 31 should be below 40%, but when the humidity reaches 70%, the same 31 will feel like 38. The reason for this phenomenon is that with the increase of air humidity, the water vapor in the environment tends to be saturated and the air pressure decreases, which not only inhibits the human body's heat dissipation function, but also affects the normal perspiration of the human body, so that the runner's backlog body temperature is too high, the regulatory function cannot play a role, and symptoms such as chest tightness and shortness of breath appear, affecting the running endurance.

At seven or eight o'clock in the morning, the sun begins to be scorching, so it is not suitable to go out to exercise, so as not to cause exertional heat stroke. It is recommended to choose the time of fitness exercise after 7 o'clock in the evening, you can do aerobic exercises such as swimming, running, tai chi, yoga, etc., which is best in an outdoor ventilated environment, about half an hour each exercise, and ensure the frequency of more than 3 times a week.
