Are your headaches caused by dehydration?


As the summer season approaches us, we will be all suffering from dehydration headaches if we don’t drink enough water to keep our body hydrated. Our body requires a lot of water to function correctly which is why every time we lose more water than usual our brain starts to signal us with headaches.

The major issue with headaches is that there are so many types of problems, each caused by different factors but they all almost feel the same which is why individuals find it hard to characterized which one is a dehydration headache. So today in this article we are going to talk about what a dehydration headache is and what are some of the significant symptoms of a dehydration headache so that you can figure it out and hydrate yourself immediately.

What is a dehydration headache?

Dehydration is a state in which our body loses more water than it gains. In summer season it could be because of extensive sweating whereas in ordinary cases it can be caused after extensive workouts, etc. Dehydration headaches are headaches that are created because of the lack of water in our brain tissues. Our brain contains 80% water and if it doesn’t have the adequate amount it starts to break down in the form of headaches.

When you become dehydrated, your brain cells don’t get enough water due to which they start to shrink and pull away from the skull causing the pain receptors to trigger which results in headaches. Dehydration also causes low blood pressure due to which the blood fails to reach the blood vessels in the brain thus they start to swell up which worsens the pain.

Dehydration headache symptoms

Dehydration headaches are very versatile. They might feel different to different people as they can take place in all areas of the head. According to some individuals, it feels like a hangover while others suggest that it is like a pulsating pain that takes place on both the sides of the head and is affected by physical activity. Thus it is quite hard to narrow it down which is why you must look for common symptoms.
