What is a dehydration headache?

Dehydration headache is the second headache, which is caused by a lack of enough fluids in the body. Dehydration headache can be as mild or severe as a migraine


Dehydration can occur after sweating when the body loses the essential fluid to function properly.

The body needs the right balance of fluids and electrolytes to function properly. Every day, especially the human body loses water through daily activities, such as sweating and urinating.


In many cases, the amount of fluid lost can be easily balanced by drinking or eating a diet rich in fluids. However, sometimes the body loses water faster than it can replenish.


During these times, the body can become dehydrated, which can lead to serious problems including unpleasant dehydration headaches.


When the body is dehydrated, the brain may temporarily contract. This mechanism causes the brain to withdraw from the skull, causing pain and leading to dehydration headache.


When rehydrated, the brain returns to its normal state, calming the head.

Drink plenty of fluids: Most people need between 4 and 6 glasses of water a day, or some people may need more or less.

Eat foods rich in fluid: Foods, such as cucumbers, other vegetables, and fruits are high in water.

Get enough fluids throughout the day: Distributing the amount of fluid used instead of drinking it all at once helps to keep the body hydrated.

Increase the amount of water during exercise or when exposed to hot weather: During heavy sweating, such as during strenuous exercise or exposure to hot weather, water requirements increase. Drinking plenty of water during these times will replenish the excess fluid lost through sweat.

Manage the underlying causes of dehydration: Fever and infection can cause the body to lose more fluids than usual. Dealing with the causes of dehydration while increasing the amount of fluid can help prevent dryness.

Avoid caffeinated beverages and alcoholic beverages: Caffeine and alcohol may increase urinary excretion, leading to an increased risk of dehydration.

Reduce hard work during the heat or if you feel uncomfortable:

Heat and sickness can increase the body's need for water. Heavy exercise can cause excessive fluid loss through sweating which can be dangerous in these situations.
