A person's sleep is mainly controlled by the biological clock. The main factor influencing the biological clock is the body's own temperature cycle. Generally speaking, people with a lower body temperature are more likely to sleep, and on the contrary, they tend to be awake.
The average person's body temperature cycle starts to rise at about 6 a.m., then decreases slightly around 2 p.m., and then continues to rise. By 10 p.m., the person's body temperature will rise to its highest. It is also the most sober time of the day for ordinary people.
So if you want to wake up your brain for a short time, you just need to raise your body temperature. Here's how:
1.Bathe with slightly warmer water and concentrate the water near the spine to quickly raise the body temperature.
2.Proper physical activity, especially short periods of physical activity after 10 p.m., can promote sleep. Make your next day better. However, it is important not to tire your body too hard.

Because when people sleep, blood circulation will slow down, and oxygen and nutrients will reduce the ** of the brain. If you sleep too long, your brain cells don't get enough oxygen and nutrients, and your ability to move will be weakened. Sleeping too long also means that the activity of muscles and tendons is reduced, and the oxygen and nutrients that muscles get from the blood are also reduced, so they become relaxed and weak, and people feel tired as a result.
Some people will go back to sleep after a morning exercise, and whether this behavior is healthy or not depends on the specific situation. Xie Yuxiao, deputy director of the Physics Department of China-Japan Friendship Hospital, reminded in an interview with the "Health Times" that if the content of the morning exercise is more strenuous exercise, such as running, it is not appropriate to sleep back after that.
This is because strenuous exercise will lead to an increase in musculoskeletal blood volume and a decrease in blood flow back to the brain, and sleeping immediately at this time will make the brain more ischemia, further increase the burden on the circulatory system, and is not conducive to the recovery of cardiopulmonary function.

Why the more you sleep, the sleepier you get.

Is it better to sleep more?
Sleep is important for good health, but the more sleep you get, the better. On the contrary, too much sleep may make a person feel refreshed. In particular, although the amount of sleep caused by some hypnotic drugs has increased, the quality has not improved, and even the phenomenon of sleepover has occurred, and the person is still tired and drowsy during the day.
For example, the daytime nap time should not be too long, and should be controlled within 45 minutes. This is enough time to recharge your energy, but if it takes too long, you will still feel dizzy when you wake up, and it will interfere with your sleep at night.
There are two types of human sleep, one is light sleep and the other is deep sleep. The two types of sleep in a normal person alternate every night. Light sleep, when the human brain does not get enough rest, is also the time when it is easiest to dream, and can recall dreams after waking up.
Deep sleep is when the human brain is fully rested, and it is not easy to be woken up at this time, and the dream is basically impossible to recall after waking up, as if there is no dream. You may be talking about less deep sleep and more light sleep every night, so it seems to be a good sleep, but the more you sleep, the more you want to sleep. In addition, people who snore severely, especially those with apnea syndrome, are like this, the more they sleep, the more they want to sleep.
Wishing you good health!

In summer, the aquatic plants have grown very luxuriantly, covering the water surface tightly At night, they cannot be photosynthetically used, and they have to absorb oxygen from the water, causing the fish to lack oxygen. The fish, shrimp and aquatic animals in the aquatic weeds swim to the bare water surface to eat, and they still swim on the bare water surface in the early morning, so they fish early in the summer and fish the surface of the water and the outer edge of the aquatic weeds. As the sun rises, the surface water and shallow water gradually become hot, and the aquatic plants carry out photosynthesis, and the water is not only shady, but also rich in oxygen, and carp, crucian carp, and even catfish and mandarin fish that are afraid of light, all return to the aquatic weeds. >>>More
