During nighttime sleep, the human body secretes growth hormone, and the adrenal cortex hormone is secreted just before dawn. These two hormones are beneficial for the metabolism of carbohydrates in the body and the development of the human body. Growth hormone is produced after falling asleep, which not only promotes the growth and development of adolescents but also delays aging in middle-aged and elderly people. Therefore, the best time for sleep in a day is from 10 PM to 6 AM.
Frequently sleeping after 12 PM can cause harm to the body, with the most direct damages as follows:
(1) Lack of sleep can damage the skin, not only making the complexion dull but also prone to acne and fine lines, and the eyes become "panda eyes."
(2) Lack of sleep can increase hormone secretion, making the body constantly unexcited, which is not conducive to physical health.
(3) Prolonged lack of sleep can directly cause physiological damage to the body, leading to loss of appetite, indigestion, decreased immune function, and triggering or exacerbating neurosis, ulcers, hypertension, insomnia, diabetes, cerebrovascular diseases, etc.
(4) Prolonged lack of sleep can cause weakened judgment, slow thinking, and poor coordination, easily leading to various accidents and causing personal injury.
(5) From the perspective of psychological medicine, the consequences of prolonged lack of sleep are quite severe.
For those who consistently sleep after 12 PM, it is advisable to consume foods rich in vitamins and collagen, such as fruits, green vegetables, and skin meats. Additionally, more cooling foods like melons, apples, millet, and coix seed can be eaten. Also, dinner should be as light as possible, avoiding spicy foods and alcohol.
However, some people do not stay up late for entertainment or relaxation. For those who work night shifts, the following points can help mitigate the harm to the body:
(1) If you must work late at night, sleep for a few hours before starting work. The closer the sleep time is to the night shift, the more effective it is in preventing drowsiness during work, thus ensuring a full day's sleep.
(2) Improve your sleep environment by using blackout curtains, or if not available, wearing an eye mask. To avoid various sound disturbances, you can also wear earplugs while sleeping.
(3) Learn to take a "midday nap." A good midday nap will give you enough energy for the day.
(4) During night shifts, take short naps whenever possible, even 20 minutes can be very effective. Additionally, you can consume caffeinated beverages like black tea or coffee to stay alert.
(5) After work, you need a breakfast rich in vitamins C and B. If possible, take a comfortable hot bath, which will help you achieve more deep sleep.
