Boycott "spring sleepy" and don't drink coffee or tea.
In spring, it is easy to feel sleepy, lethargic and inefficient. Although "spring sleepiness" does no great harm to people, the minor harm is also endless, especially for people who are engaged in high-risk jobs or driving. Nowadays, there are not a few people who drink coffee to resist "spring sleepiness". In this regard, experts suggest that drinking coffee is not recommended. Drinking coffee is likely to cause arteriosclerosis and affect normal sleep. If you need a pick-me-up at work, you'd better drink black or green tea.
According to Zhou Li, director of the Clinical Nutrition Department of the first affiliated Hospital of Suzhou University, the phenomena of "spring sleepiness" are emotional instability, lack of deep sleep, dreamy and easy to wake up, low spirits, and easy to doze off at ordinary times. Spring sleepiness is a response to the physiological changes brought about by the change of seasons.
In winter, the human body is affected and stimulated by low temperature, the capillaries of the skin contract, blood flow is relatively reduced, sweat glands and pores are also closed, reducing heat emission, in order to maintain normal body temperature. After entering spring, with the gradual rise of temperature, people's body pores, sweat glands, blood vessels begin to dilate, skin blood circulation is also exuberant. At this point, the blood supply to the brain is relatively reduced. With the warming of the weather, the human body's metabolism is gradually exuberant, and the oxygen consumption is constantly increasing, the oxygen supply to the brain is bound to appear insufficient. Coupled with the benign stimulation of warm temperature, the brain is suppressed to some extent. As a result, people will feel sleepy and sleepy and always feel that they don't get enough sleep.
Zhou Li said that to alleviate the "spring sleepiness", in addition to maintaining a happy mood, we should also pay attention to eating more protein-rich foods, such as fish, eggs, chickens, ducks and geese. Eat more vegetables containing K, such as spinach, leek, tomato and kelp.
