6 tips to prevent “spring sleepiness” while driving

　　Spring sleepiness is a short-term physiological phenomenon in which the human body's physiological functions are adjusted accordingly with natural seasonal changes and temperature changes. In spring, the temperature is moderate, skin and muscle microvessels are in a relaxed and relaxed state, the blood flow is slow, the blood supply to the body surface increases, and the blood flowing into the brain decreases accordingly, and the central nervous system nerve The excitatory stimulation information of the system weakens, so the "spring sleep" phenomenon of drowsiness occurs. Therefore, when driving in spring, you must pay attention to the following points.

　　1. Turn on the air conditioner less often when driving. Turning on the air conditioner can easily cause insufficient oxygen in the car, leading to brain hypoxia and lowering alertness. Perfume containing mint and lily scents can be placed in the car to help refresh you.

　　2. Don’t smoke while driving. Smoke contains nicotine and carbon monoxide. Nicotine has an excitatory effect on the nervous system in the early stage, and an inhibitory effect in the later stage, causing people's attention and memory to gradually decline. Carbon monoxide can combine with hemoglobin in red blood cells, reducing the normal oxygen transport capacity of red blood cells, causing the body to become drowsy due to lack of oxygen.

　　3. Don’t rely on coffee Or strong tea to refresh you. Coffee and strong tea can only bring temporary excitement, but they cannot enable you to observe the road clearly and make correct reactions. Moreover, the short-term excitement is followed by a continuous state of inhibition.

　　4. If you feel sleepy while driving, you must rest. Generally, after every 3-4 hours of driving, you should stop for some exercise and take a deep breath. If you feel tired while driving, don't force yourself to drive. Be sure to stop and rest, get out of the car and stretch your body before getting back on the road to ensure safe driving.

　　5. Pay attention to dietary adjustments. In spring, Yang Qi grows. Pungent and sweet foods help to raise Yang, and warm foods help to protect Yang. Ginger, onions, and leeks should be eaten in moderation, and yellow-green vegetables such as carrots and cauliflower should be eaten regularly. In addition, it is best not to consume large amounts of milk, bananas, lettuce, fatty meats and alcoholic foods (such as liqueur chocolate, etc.) before driving. Such foods can easily make people feel tired or cause obvious drowsiness and fatigue, and have a hypnotic effect.

　　6. Get enough sleep. Maintain a normal pace of life, avoid excessive nightlife, stay up all night for entertainment, and avoid excessive "burning the midnight oil" to avoid inducing or aggravating spring sleepiness. According to statistics, in traffic accidents caused by fatigue, 60% of drivers slept less than 3.5 hours the day before.
