What should I do if I feel dizzy, have a headache and sweat easily in summer?

Every time we enter midsummer, many people often experience headaches and dizziness. In severe cases, it can affect daily life and work. What is the reason for this?

First, in summer, the temperature is high and the heat is overwhelming. The human body sweats a lot in order to dissipate heat and cool down. If water is not replenished 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. Hence the headache. In addition, when the human body sweats, blood vessels on the body surface expand, and blood is shunted from the inside out. The redistribution of blood will cause people with low blood pressure to lower their blood pressure even more, causing headaches. Medically, this is called intracranial pressure or hypotensive headache.

Second, people often have headaches in summer due to poor sleep, weak spleen, and poor appetite. The cause of this type of headache is malnutrition and low blood sugar, which causes the brain to lack the necessary energy and cause headaches.

Third, people are accustomed to drinking cold drinks in summer. Although cold drinks are sweet, refreshing and refreshing, some people will have headaches after opening a cup and drinking freely. This is because the hot mouth and mucosa cannot withstand the sudden stimulation. This stimulation causes the submucosal blood vessels to spasm, and at the same time reflexively causes cerebral vasospasm. This is short-lived, but it makes the brain unable to tolerate this sudden attack. The blood flow is cut off and the person cannot respond to stress quickly, causing headaches. This type is called cold drink headache.

In fact, the key to preventing and treating summer headaches is to meet the brain’s demand for energy. The prevention and treatment measures are as follows:

1. Prevent heatstroke and cool down, avoid working in a high temperature environment for a long time, and try to Reduce the body's energy consumption.

2. Replenish water in time, preferably drinking warm boiled water, and eat more vegetables and fruits to replenish water, vitamins and salt loss.

3. Eat light and easy-to-digest food, and often drink sugary drinks.

4. People who have headaches due to drinking cold drinks should avoid drinking cold water.

5. For dehydration headaches, in addition to replenishing water in time, you should also lie in a low pillow or no pillow position to allow as much blood to flow to the brain as possible.
