First, staying up late will increase our cortisol.

First of all, we need to make sure that staying up late will lead to protein's dissimilation hormone in our body, and cortisol will also increase. Cortisol is a hormone secreted by the adrenal cortex of our body. According to chemical classification, this hormone belongs to the same kind of hormone as androgen and estrogen in everyone.

The function of cortisol is to inhibit the oxidation of sugar, promote the conversion of protein absorbed by us into sugar, and raise our blood sugar, which is obviously absolutely harmful to our fitness, so we must avoid the increase of cortisol.

Second, staying up late will lower our testosterone.

Friends who have been healthy should know something about testosterone. Testosterone is the best hormone for our muscles to synthesize faster. The reason why men can grow muscles faster than women, and the level of strength growth is greater, is also related to testosterone, because women's testosterone secretion is only 1 1 of men's, so the role of testosterone in us can be seen.

Staying up late will reduce the anabolic steroids testosterone and IGF- 1 in our body. IGF- 1 refers to insulin-like growth factor, which is mainly secreted by the liver and plays the role of synthesizing muscles. Testosterone is mainly secreted by our testicles, which can help our muscles grow and improve endurance.

Third, staying up late will reduce our muscle glycogen level.

Although muscle glycogen accounts for only a small part of our muscle mass (about 1%-3%), the existence of glycogen can retain part of water, so it can maintain part of our muscle volume, because as long as there is one unit of glycogen in our muscle, we can save 3-4 units of water, and the benefits of water to our human body are needless to say.

Creatine, too, can enhance our body's water storage capacity. Therefore, during taking creatine, our weight is generally much larger than when we don't take it. This is the importance of water storage.

Extended data:

Staying up late can cause many kinds of damage to the body:

Frequent fatigue and decreased immunity: the most serious sequela caused by staying up late is fatigue and lack of energy; The immunity of the human body will also decline, and symptoms of autonomic nervous disorders such as colds, gastrointestinal infections and allergies will appear.

Headache: On the second day after staying up late, I often have a headache when I go to work or attend class, and I can't concentrate and even have a headache. Long-term staying up late and losing sleep also does intangible harm to my memory.

Dark circles and bags under the eyes: Night is the physiological rest time of human body. Without rest, the blood circulation around the eyes will be blocked because of excessive fatigue, resulting in dark circles, bags under the eyes or bloodshot eyes.

Dry skin, long black spots and acne: 165438+ 0: 00 pm to 3: 00 am the next day, which is also the time when the human meridians run to the gallbladder and liver meridians. If these two organs don't get enough rest, they will appear on the skin, which is prone to problems such as rough skin, yellow face, long black spots and acne. For those who are used to going to bed early, they should go to bed at 1 at the latest. And to make matters worse, staying up late for a long time will gradually lead to insomnia, forgetfulness, irritability, anxiety and other neurological and mental symptoms.
