4hw.com.cn: I always feel listless recently? Listless all day? The weather is getting hotter and hotter, especially after lunch, the whole person is in a state of drowsiness, from early to late. Why are you sleepy in summer? Let's have a look.
What are the reasons for sleepiness in summer
The days are long and the nights are short.
In summer, due to the long day and short night, people sleep late and get up early, have more parties, and are relatively lack of sleep. After a morning of study and work, they may feel tired. Coupled with the lack of oxygen in the brain after dinner, they naturally want to doze off at noon. In summer, the days are hot and long, and the nights are cooler. Some people arrange some activities at night. In addition, the hours at night are short, and people's sleep is less. In this way, the biological clock is disordered, and people are prone to sleepiness during the day.
Sweating at high temperature
The excessive temperature and sweat during the day make the human body sweat a lot, which leads to fatigue, low spirits and sleepiness. It often feels low spirits and drowsy. In the case of severe high temperature operation, the human body perspires a lot and loses a certain amount of potassium element, resulting in electrolyte disorder, affecting the normal operation of the human body, making people feel tired and powerless.
Poor living habits
Many people's sleepiness comes from their bad life. Especially in summer, it is easy to go to bed late because of the hot and long day. Sleeping late, eating late and other habits are easy to damage the spleen and stomach. If you are particularly sleepy after meals, it is the spleen that warns. Experts say that the spleen is often associated with organs such as the gastrointestinal tract. Once spleen deficiency occurs, it will produce: anorexia, loose stool (thin, soft) and other symptoms.
Stay in an air-conditioned room for a long time
In air-conditioned rooms, windows are often closed, airless, and carbon dioxide is increased. In the long run, the brain will suffer from hypoxia and sleepiness. Therefore, people who stay in the air-conditioned room for a long time should go out and breathe in time to supplement fresh air for the brain.
The spleen and stomach are left behind
Spleen and stomach are most closely related, and some symptoms of weakness of spleen and stomach appear, such as dozing. After eating, blood sugar rises, blood supply to brain is insufficient and sleepy. There are two ways to improve it: one is to adjust work and rest, regulate life, and ensure enough sleep; the other is to achieve the effect of invigorating the spleen through dietotherapy. Experts especially recommended some ingredients with the effect of invigorating the spleen and moistening the body: yam, tuckahoe, job's tears, etc.
Damp heat
In summer, the weather is humid and hot, which is a season of easy injury and gas consumption. 'summer heat' is the main Qi of summer, for 'Yang evil'. Summer heat is easy to damage the body fluid. Once the injury occurs, it is easy to produce sleepiness, fatigue, shortness of breath, sweating and other symptoms. Heatstroke can last for a long time. You may as well take some home medicine such as Huoxiang Zhengqi pill and biewendan to improve it.
In summer, due to the heavy rain and humidity, it is easy for people to 'accumulate humidity'. Especially now we all use air conditioning. Once it's cold and hot, it often makes the humidity 'turbid'. The specific symptoms are chest tightness, dizziness, body sleepiness and so on. Experts say that if the discomfort is caused by heavy moisture in the body, you can eat some dehumidified food to improve it, such as job's tears, lotus seeds, red beans, etc.
Seasonal biological clock
The biological clock caused by the seasonal relationship can not be adjusted, but they work under great pressure, are angry and easily fidgety, have poor ability to adapt to the change of seasons, resulting in psychological adjustment, but this is a rare example.
Xia Xia phenomenon
