"Sleepy in spring, sleepy in autumn, sleepy in summer, sleepy in winter and sleepy in March" is the mantra of people who love to sleep. Poetry reflects the physiological response of human body in different seasons.
Extended information In spring, people are sleepy, but they feel lazy and yawn. Not only are you sleepy, but ancient people are also sleepy. Women in the Qing Dynasty bought radishes every day at the beginning of spring, which is called "biting spring". It sounds delicious and interesting. They think it can solve the problem of spring sleep. Sleepiness in spring is not a disease, but a response to physiological changes brought about by seasonal exchange.
In autumn, the climate is cool and pleasant, the human body sweats less, the body enters the stage of periodic dressing, the water and salt metabolism gradually returns to balance, the burden on the cardiovascular system is reduced, and the digestive function returns to normal. At this time, the body feels tired, which is autumn fatigue.
In hot summer, people sweat a lot, which leads to imbalance of water and salt metabolism, weakened gastrointestinal function, increased burden of cardiovascular system, and people's body is in the stage of excessive consumption. It's not hard to understand. It's hot in summer, bad rest at night, and easy to get sleepy during the day.
