“The vernal equinox, the yin and Yang half of the same. Therefore, the day and night evenly and the cold and heat level.” Vernal equinox equalizes the day and night, cold and heat. With the gradual warming of the temperature, “spring sleepiness” also comes. First, sleep less, brain hypoxia to spring sleepiness First of all, the spring sleep time becomes shorter. According to Chinese medicine, when yin energy is strong, you sleep, and when yang energy is strong, you wake up. In other words, when nature’s yin is strong, people should go to sleep, and when yang is strong, people should wake up. Spring is earlier and longer than winter sunshine, while sleep time becomes shorter. Spring should be relatively “late to bed and early to rise”, sleep can be properly adjusted to about 11:00 pm, and the morning should be up at about 6:00 am. In addition, due to the rise in temperature in spring, the body temperature rises after the blood supply mechanism changes, is another reason for the occurrence of “spring sleepiness”. In order to adapt to this change, the blood distribution of the human body will be redistributed. The blood supply to the brain and other important organs will be relatively reduced due to the relative increase of blood in the skin and periphery. Lack of oxygen to the brain, insufficient blood to the heart, “spring sleepiness” thus occurred, people are prone to fatigue, often yawn. Second, snooze should not be more than half an hour to relieve spring sleepiness, there should be 15-30 minutes to take a nap at noon, even if the eyes can be closed to reduce fatigue. Some people think that after lunch can not sleep immediately, in fact, this is a misconception. After eating the blood flow in the gastrointestinal tract will increase, the brain blood supply to further reduce, more easily sleepy, this time a nap is also natural. However, it should be noted that the snooze time should be limited to half an hour, if the nap time is too long, it is easy to make the desire for sleep at night to reduce the original sleep pattern. Third, the weekend “sleep” should sleep early Weekend is often the most anticipated rest time for office workers, they usually use the weekend two days to make up for the lack of sleep time on previous working days. However, research results show that the weekend sleep will not play a role in compensating for sleep, but will often make people feel more tired on Monday. This is because the bedtime is not relatively fixed, disrupting the biological clock in the body previously. If you want to catch up on sleep, using the usual 30 minutes is enough. According to research, a normal adult sleeps 7-8 hours a day is enough. An effective way to catch up on sleep on weekends is actually to go to bed a little earlier than on weekdays, while the wake up time should be the same as usual, so that the body can adjust to the best condition, and this method even works for insomnia.
