People often say that "spring is sleepy and autumn is short, and summer is a nap." Why is it easy for people to feel sleepy in spring, and how to prevent and drive away the tiredness in spring? "Spring Sleepiness" is because the climate is getting warmer after the severe winter, and the blood flow of capillaries on the human body surface needs to be increased because of stretching. At this time, the blood flow of brain tissue will decrease accordingly, resulting in insufficient oxygen supply to brain tissue, resulting in lethargy, fatigue and lethargy. Although this is a normal physiological phenomenon that human physiological functions change with seasons, these physiological changes may also cause some diseases. Related research points out that the "spring sleep" can easily cause people's anxiety and confusion. Second, it is easy to get angry. People often feel thirsty and get angry easily. Some people even have pimples and acne on their faces. Experts remind that "spring sleep" is actually a signal that the body is in sub-health. It is suggested to prevent it from the following aspects: First, to ensure adequate sleep, wash your face with cold water after getting up in the morning, because washing your face with cold water can stimulate the skin and brain, thus stimulating changes in blood circulation as soon as possible.

Secondly, pay attention to indoor ventilation, take a lunch break, and try not to stay up late at night. Finally, doing more exercise can speed up the brain's response to information processing, improve the body's metabolic process, promote blood circulation, and have a good stimulating effect on the central nervous system and endocrine system. As long as you pay attention to the following four tips, you can easily eliminate the "spring sleep". One is to stimulate the touch. When you feel sleepy and tired, brushing your teeth and rinsing your mouth with fragrant toothpaste and washing your face with cold water can improve the excitement of your nervous system, thus quickly returning to a state of full spirit. The second is to stimulate vision. You can go outdoors, to the suburbs, lakes, beaches or mountains, and look up. If you look forward to staying indoors for a long time, you can consider adding some colorful and energetic ornaments and flowers. This kind of good visual stimulation gives people a pleasing feeling and makes people feel refreshed. The third is to stimulate the taste. You can eat some bitter and spicy food, or make a cup of strong tea or coffee to get rid of drowsiness. The fourth is to stimulate the sense of smell. When you are sleepy, you can smell the essence of wind oil, cool oil, toilet water and lit sanitary incense. All these things can play a refreshing role. If we can adjust measures to local conditions, it is also good to plant some fragrant and refreshing seasonal flowers and plants in the living room, balcony or courtyard.
