The weather is sultry, how to solve headache and vomiting?

Every summer, many people often feel headache and dizziness, which will seriously affect their daily life and work. Why is this caused?

First, the summer temperature is high, and the summer heat is pressing. The human body sweats a lot to cool down. If you don't replenish water in time at this time, the blood volume of the human body will be reduced, and the blood supply to the brain will be insufficient, leading to headache. In addition, when people sweat, the blood vessels on the body surface dilate and the blood is diverted from the inside out. The redistribution of blood will lower the blood pressure of people with low blood pressure, thus causing headaches, which are medically called intracranial pressure or hypotensive headache.

Second, in summer, people often have headaches because of poor sleep, weak spleen and stomach and poor appetite. This kind of headache is caused by malnutrition and low blood sugar, which leads to the lack of necessary energy in the brain and headache.

Third, people are used to drinking cold drinks in summer. Although cold drinks are sweet and refreshing, some people will have a headache after drinking one. This is because the burning mouth and mucous membrane can't stand the sudden stimulation, causing submucosal vasospasm. At the same time, the reflex vasospasm is short-lived, but it will make the brain unable to stand this sudden blood loss and make a quick stress response, which will make people have a headache. This kind of headache is called cold drink headache.

In fact, the key to prevent and treat summer headache is to meet the brain's demand for energy, and its preventive measures are as follows:

1, heatstroke prevention and cooling, avoid working in high temperature environment for a long time, and minimize the energy consumption of the body.

2. Replenish water in time, it is advisable to drink warm water, eat more fruits and vegetables to supplement water, vitamins and salt-free losses.

3. Eat light and digestible food and often drink sugary drinks.

People who have a headache due to cold drinks should avoid drinking cold water.

5. In addition to replenishing water in time, you should also take a low-degree pillow or no pillow position to make blood flow to the brain as much as possible.
