Dizziness and headache in summer

The symptoms of headache are unbearable for most people because headaches mostly occur in the brain and other tissues, which contain abnormally abundant nerve cells, and the pain they cause to people is very intense. Dizziness and headaches are often accompanied by each other, and some patients also experience seasonal headache and dizziness symptoms. For example, summer is the peak season for dizziness and headaches. Let’s take a look at what causes dizziness and headaches in summer?

First, the increase in ambient air temperature causes the blood vessels in the human skin to dilate and become congested, and the blood flow in the gastrointestinal blood vessels to decrease relatively, resulting in decreased digestive function and loss of appetite. The body lacks nutritional supplements, resulting in fatigue and weight loss;

Second, people sweat a lot in summer, and most people excrete a lot of water and salt every day. When the body lacks salt, the secretion of gastric acid will be reduced or disordered;

Third, in summer a large amount of blood flows to the skin blood vessels, resulting in insufficient blood supply to the brain, causing brain hypoxia.

At the same time, the weather is hot in summer, with short nights and long days. The long days increase human activity and the high temperatures increase human metabolism, all of which greatly increase energy consumption. The short night also shortens the original normal nighttime sleep time. Coupled with the disturbance of mosquitoes, people cannot get enough sleep and the cerebral cortex cannot get sufficient protective inhibition. This kind of excessive mental and physical exertion will make people feel tired and drowsy.

In order to prevent or alleviate the "bitter summer", we should strengthen physical exercise and improve our ability to adapt to the environment. In addition, due to the vigorous metabolism of the body in summer, the decomposition and excretion of protein in the body increases relatively, and the protein in the body is often in a state of relative deficiency. Therefore, you should eat more nutritious high-protein foods in summer, such as fresh fish, lean meat, eggs, soy products, etc.

In summer, people's appetite is poor, so it is not necessary to eat three meals a day at fixed times. Eat when you want to, and eat as much as possible until you are full and eat well. Adjusting the food variety is very important to promote appetite. We should work hard on the variety of meals, such as cold cucumbers, sugar-mixed tomatoes, mung bean porridge, etc. These foods are not only refreshing and delicious, but also can supplement the needs of the human body.
