Heat release accounted for 50% of the causes of core body temperature changes, and the increase of body fat rate (the range of body fat changes of subjects was 6.8% – 32.5%) accounted for only 2.3% of the changes.
They believe that previous studies on the amount of perspiration have such problems, that is, the degree of obesity and maximum oxygen uptake affect other factors of the body.
Suppose that two people with different maximal oxygen uptake exercise together, and both use 70% of the maximal oxygen uptake to exercise.
There are many factors that affect thermoregulation.
So if you want to know why your body sweats more than others in hot weather, it is useless to simply look at fat and aerobic capacity.
The following suggestions based on research can be adjusted appropriately according to the comprehensive assessment of individual water and electrolyte loss in different environments..
The more fat, the thicker, the faster the body heats up during exercise.
Hot weather, stress, embarrassment, or physical discomfort can make you sweat more.
Click on the blue words above, remember to pay attention to us! Why do you sweat during exercise? During exercise, the human body releases a lot of heat due to work, which makes the body temperature rise.
Before running, we were depressed and everyone was unhappy.
It should be pointed out that this does not conflict with previous studies that people with more fat tend to sweat more.
For example, a series of factors such as everyone’s personal constitution, environmental temperature and health level.
Gender is also a major factor affecting the amount of sweating.
The change of weight can clearly show how much you sweat during running.
Sure enough, the change of the core temperature (usually refers to the rectal temperature of the human body) of the subjects can be explained as the heat generated by pedaling per unit of weight, rather than the “heat insulation effect”.
Research shows that weight is the key.
The researchers explained that although women have more sweat glands than men, they produce less sweat per gland on average than men.
For example, measure your weight before and after running.
Although it sounds against common sense, it can be explained again by how much energy the body produces.
In fact, this is not the case.
Why do I sweat more than others? There are many factors influencing the amount of sweating.
This is why many men have a strong smell of sweat in the summer.
They asked the participants to do a series of 60 minute cycle tests with different intensities, and measured their sweating volume and body temperature changes at the same time.
Their study, published in the Journal of Applied Physiology, was surprising.
This is the effect of sweating.
But that’s not the point.
However, if you always sweat too much, especially in a certain part of the body (such as armpit, foot, hand or face), you may have hyperhidrosis or the side effects caused by diabetes and hyperthyroidism, so you need to see a doctor in time.
This proves that when two people of the same weight pedal their bicycles at the same pace, their body temperature should rise at the same rate, even if one person is short and fat and the other is tall and thin.
Matthewcramer of the University of Ottawa in Canada and olliejay of the University of Sydney put forward different views.
You’d better rely on your own experience and some small tests to judge.
Therefore, more sweat needs to be excreted to regulate body temperature.
Davidparizer, an American medical doctor, said that more than 99% of sweat is water and a small amount of electrolyte.
We all have this experience.
There are many people who think that sweating can detoxify.
The more you sweat, the better? Sweating during exercise can stimulate the production of endorphins in the brain, and then change your mood and control mood fluctuations.
People who are fat tend to weigh more – so is it the heat insulation of excess fat that makes the body sweat more? Or does the body need to move more weight and do more work so it sweats more? In order to determine the most critical influencing factors, Kramer and Jane Lee convened 28 volunteers with different weights and different aerobic capacity to test.
The previous view also believed that a long-distance runner has a higher maximum oxygen uptake, and can sweat more quickly during exercise, so as to run faster and farther, which is also considered to be the embodiment of high sweating efficiency.
But after running, we became happy.
As mentioned above, you can determine it by measuring the weight difference before and after running.
Everyone has a benchmark level of sweating.
Among the many influencing factors, previous studies generally believed that the main factors determining the amount of sweating were body fat rate and aerobic capacity (aerobic capacity is an important indicator to measure a person’s exercise level, and the commonly used evaluation method is maximum oxygen uptake).
Studies have shown that men sweat more than women.
So the more you sweat, the better.
In order to regulate body temperature, nerves will stimulate sweat glands to release sweat, which will take away part of body heat through transpiration.
Similarly, the maximal oxygen uptake itself is not the key factor affecting the amount of sweating, it only accounts for 4% of the influencing factors.
Human beings are thermostatic animals.
The same is true of the sweating rate of the body: the body fat rate accounts for only 1.3%.
Only a few toxic substances are discharged from the body through sweat glands, but the body’s detoxification mainly occurs in liver, kidney and other organs, not through the skin.
But a person sweats more not because of the thermal nature of fat, but because the body needs to do more work to produce more heat and sweat.
How to replenish water after sweating? The most relevant thing to sweating is water replenishment.
So sweating itself can keep people cool and make runners run longer.
People with strong aerobic capacity pedal their bikes or run faster, so they generate more heat and sweat more, but that is because they do more work, not because of the efficacy of maximal oxygen uptake itself.
Researchers generally believe that fat has the function of heat insulation.
