Why do I always feel sleepy when the seasons change?

Spring is sleepy, autumn is lacking, summer takes a nap, and winter is March when I can't wake up. In addition, there is also Bai Juyi's Spring Sleep without Feeling the Dawn, both of which express people's mental state during the change of seasons. Of course, this state is neither a manifestation of disease nor permanent. It mostly appears during the change of seasons. And this statement actually has a certain scientific basis.

People may feel sleepy as soon as spring arrives. The main reason is that the weather gets warmer in spring and the temperature continues to increase. The pores and blood vessels of the human body begin to relax, the metabolism of the blood and human body accelerates, the oxygen content required by the human body also increases, and the oxygen consumption continues to increase, causing brain damage. Blood supply is relatively reduced. Coupled with the stimulation of the human body by warm temperatures, brain function is inhibited to a certain extent, resulting in drowsiness. In addition, compared with winter, the daylight hours in spring are longer, causing people to go to bed later and get up earlier, which conflicts with the biological clock in winter, resulting in insufficient sleep and feeling like they can't wake up no matter how much they sleep!

People also feel sleepy in summer. The main reason is that due to the rotation of the earth, the daytime is longer than the night in summer, resulting in relatively less sleep time. In addition, the temperature in summer is higher, which affects the quality of sleep. At the same time, the blood flow is accelerated and the human body consumes a lot, resulting in a relative lack of blood supply to the brain, which in turn creates the desire to take a nap.

In autumn, people feel tired easily. The main reason is that the high temperature in summer takes a huge toll on the human body. In autumn, the weather gradually turns cooler and the body enters a stage of self-adjustment. Autumn fatigue is an important manifestation of the recovery of human physiological functions. Of course, autumn fatigue is only a temporary manifestation, will not last too long, and will not have a great impact on people's lives. In addition, the cool temperatures in autumn create a comfortable sleeping environment for people, which is also a major cause of autumn fatigue!

The physiological demand for sleep is greater in winter. People are warm-blooded animals. The temperature drops in winter and the body's heat is constantly lost. If you do not stay in a warm room and maintain a low level of consumption through sleep, It is easy to cause additional heat loss.

There will be a state of being unable to wake up every quarter. These are normal physiological phenomena and people do not need to pay too much attention to them.

During the change of seasons, you should pay attention to your diet, daily routine, and get enough sleep!
