What is the manifestation of spring sleepiness? Sleepiness, drowsiness, lack of energy, yawning, always want to sleep, “sleepy”, because the performance in spring is more obvious, commonly known as “spring sleepiness” or “spring fatigue”. Why do you get sleepy in spring? In the cold winter, although people do not hibernate, but the body will naturally be in a relatively low metabolic state, the whole body blood flow is relatively reduced, sweat glands and pores are also closed, reducing the distribution of heat to maintain the normal body temperature, wait until spring, when everything is revived, with the rise in temperature, the body surface pores, sweat glands, blood vessels began to stretch, the skin blood circulation is also strong, so that the blood supply to the brain will be relatively reduced. The blood supply to the brain will be relatively reduced. And as the weather warms, the body’s metabolism gradually flourishes, the total oxygen consumption is constantly increasing, the oxygen supply to the brain is bound to be more inadequate, as we know, the lack of blood and oxygen supply to the brain will lead to drowsiness and sleepiness. Of course, other factors that can cause cerebral ischemia and hypoxia can also cause drowsiness, such as overuse of the brain, lack of sleep, too much food and drink can also cause the same symptoms. Can over-eating also cause spring sleepiness? Yes, after a full meal, the body’s blood is mobilized to the digestive system to work, and the brain, a major oxygen consumer, seems to be underpowered. So spring sleepiness is a natural phenomenon, not enough to worry about? If it is only the climate or some physiological activities that cause drowsiness, you can improve drowsiness through rest and self-regulation of the human body, the human body is the most complex and mysterious machine, spring sleepiness is a reminder and protection for you. Spring sleepiness itself is not a disease, but it can also affect people’s study and work, especially for students, white-collar workers, people working in institutions, and drivers. As a doctor also want to remind people that similar performance may also be the precursor of some diseases, such as heart disease, hepatitis, high blood pressure, and especially to remind the elderly to pay attention to be alert to the risk of stroke. In elderly people, especially those with a history of heart disease and hypertension, altered mental status and drowsiness can be a high risk sign and cannot simply be attributed to springtime sleepiness. How to prevent springtime sleepiness? There are causes before there are consequences, and if you eliminate or reduce some of the causes that I analyzed earlier, springtime sleepiness will improve very well. The first thing is to exclude diseases, and the second thing is to improve the blood and oxygen supply to the brain. How to improve it? I think there are several aspects: one is a regular life, the most important of which is sleep and diet. To deal with spring sleepiness is not simply more sleep, sometimes the more sleepy, because the normal adult sleep 7-8 hours a day is enough, and then more instead to inhibit brain function, the more sleepy. So we advocate regular sleep and quality sleep. What do you mean by quality sleep? Do you have the experience that sometimes you wake up fresh and refreshed, and sometimes you wake up groggy and can’t lift your spirits for half a day, and it’s not necessarily proportional to the length of sleep? Yes, there is such a situation, why? Sleep state is a cycle, alternating cycles of deep and light sleep, generally lasting from one and a half to two hours for a cycle, regular sleep is to choose to sleep at a relatively fixed time every day, the body itself to adjust the biological clock to the corresponding time, after this point will often happen to fall asleep difficulties. And if you wake up in a deep sleep, often feel very tired, if you choose to get up at light sleep time with a more refreshed spirit, so sometimes there are 7 hours of sleep than 6 hours more sleepy phenomenon. My recommended bedtime for everyone is 7.5 hours + a half hour lunch break. It seems that there is a learning curve inside the sleep, so what else to pay attention to? Diet, eat too much, too greasy will increase the burden on the digestive system, causing drowsiness, so eat fewer meals, reasonable diet, eat more vegetables and fruits can reduce drowsiness, and now some people like to lose weight in the spring, if the method is not scientific enough, excessive diet, the body does not have enough energy, will also lead to drowsiness. In addition, the most important thing is to exercise, spring sleepiness why in the brain workers especially prominent performance? It is because the time and intensity of their brain is too large, especially the left brain hemisphere in charge of learning and thinking more rest, so the general continuous study or desk work for an hour, should be relaxed for 5-10 minutes. These short minutes can be adapted to local conditions, moderate physical exercise, activities, exercises, listening to music can be, or at least take your eyes away from the book or computer, look at the distant scenery, stretching. In short, shift your attention, let your stiff body relax, and do not let a functional area of the brain in a constant state of congestion. Urban white-collar workers who are in a position to do so, take advantage of double days off and holidays to go to the countryside or at least walk outdoors.
