1, running time is too short.
Running for too short a time may cause you to run without sweating. Because sweating is caused by excessive body heat, you need to dissipate heat through sweat glands. However, if the running time is too short and does not generate a lot of calories, and the body thinks it is unnecessary to sweat, it will not sweat or sweat too little.
Suggestion: the running time depends on the individual situation. Run more when you have more time, and it doesn't matter if you don't sweat when you have less time, which also achieves the purpose of exercise.
2. Underdeveloped sweat glands
Running without sweating may be caused by underdeveloped sweat glands. If you exercise for a long time and feel very hot, but you just don't sweat or sweat less, it may be because your sweat glands are underdeveloped, because the amount of sweating depends on the secretion of sweat glands.
Suggestion: the sweat glands are underdeveloped, so it is not good for your health to sweat in time and eliminate some harmful substances. You can develop sweat glands through exercise, especially if you sweat every time you exercise, you will be fine.
Note: people with underdeveloped sweat glands have poor heat dissipation function and are prone to heatstroke. Try not to exercise when the outdoor temperature is too high.
3. Low body fluid content
Running without sweating may also be caused by low body fluid content. Some people have more body fluids and sweat more when exercising; On the contrary, there is little or no sweating during exercise. The amount of body fluid is determined by the body fat content. The more fat there is, the less water there is, so fat people have less body fluids than thin people.
Suggestion: As long as you are healthy, sweating less is not a nuisance, so don't worry too much.
4. Drink less water before exercise
Drinking too little water before running can also lead to running without sweating After all, sweat is ultimately discharged from the inside of the body. In addition to the body fluids in cells, most of the water in the body still depends on drinking water, so drinking too little water before running will also lead to no sweating or less sweating.
Suggestion: It is recommended to replenish proper amount of water before running in the morning, and to replenish water in time during running, so as to avoid water shortage during exercise and make the body sweat.
5, personal physical quality differences
Whether you sweat during running depends on your physical fitness. People with strong physique have relatively healthy muscles and motor organs. Even if they exercise harder, they naturally have no strength and sweat less. On the contrary, people with poor health will sweat a little.
Suggestion: Regular exercise helps to improve physical fitness, and the normal diet should be adjusted reasonably. Eat more fruits and vegetables, protein food and less spicy and greasy food.
6, cold and cold
When running without sweating, you should also consider whether you have a cold. Wind-cold colds are more common in winter and spring, and are generally caused by exogenous wind-cold. When you catch a cold due to wind-cold, your body will spontaneously close your pores to prevent the invasion of cold, which is called wind-cold closing the exterior in Chinese medicine.
Suggestion: After catching a cold, in addition to actively treating the cold, you can do light exercise, try to do less strenuous exercise and pay attention to rest.
7. No sweat
Patients without sweat do not sweat or sweat less when running. The causes of anhidrosis may include sweat gland dysfunction and nervous system injury, and other skin diseases may also lead to anhidrosis. Moreover, patients with anhidrosis often feel unwell and extremely tired, and the local skin will be very dry and rough, and skin lesions will appear.
Suggestion: When suffering from anhidrosis, you should follow the doctor's advice to avoid being in a high temperature environment and strenuous exercise to prevent heatstroke. When the body temperature is too high, physical methods can be used to cool down.
8. Benefits of running at different times
Morning running can stimulate nerves, make people awake, flexible and quick-thinking. The air quality in the afternoon is better, and people's health is the best at this time. Running during this time can also reduce the harm of air pollution; After running home at night, the brain secretes more melatonin and hormones, which can promote the growth and development of teenagers, enhance immunity and effectively improve the quality of sleep.
