When you don’t get enough water, your brain tries to compensate by increasing blood pressure and sending chemicals throughout your body to make you feel facial pain.
It’s like when you have a headache after not drinking enough water or bright lights —it’s a warning that your body is dehydrated.
Headaches caused by dehydration can be moderate or severe. You could experience discomfort throughout your head or only in one area, such as the side of the head. Usually a mild discomfort, the head pain can occasionally be intense.

- experiencing dry mouth, lips, and eyes,
- feeling sluggish or lightheaded
- dark urine with a strong odor
- passing only small amounts of urine less than four times a day
Dehydration is a bodily condition that occurs when there are fewer water molecules in the blood than average. Dehydration is measured by how much fluid intake you lose daily, and it can lead to serious health problems, including light-headedness and fatigue.
Your body needs two liters of water daily or more on a hot day. The amount of water you need depends on your weight, climate, and physical activity level.
Drinking too much liquid can cause bloating or diarrhea. But if you’re dehydrated, your body may not be able to absorb enough nutrients from food or other sources. This may result in weight loss, anemia, and even kidney failure.

Can dehydration cause headaches behind the eyes?
This is because dehydration causes decreased blood flow to your brain tissue, which puts extra pressure on the arteries on the sides of the head and causes them to constrict.
This causes migraine headaches behind the eyes because blood vessels in your skull are more minor than elsewhere in your body.

Other reasons such as poor diet or not drinking enough water.
Headache dehydration, brain shrinkage
The brain is often studied concerning its function. One such study has looked at how dehydration affects the brain and its ability to function. The results were surprising, and we’d like to share them with you!
In their study, medical emergency researchers found that chronic dehydration caused shrinkage in some brain areas, including the hippocampus and cerebellum.
This shrinkage was reversible once hydration levels were restored, suggesting dehydration may cause brain chemistry changes.
They don’t last long enough to have any natural effect on mental functions.
Can brain damage from dehydration be reversed?
It is possible to reverse brain damage from the risk of dehydration. While this may seem like a far-fetched idea, it is pretty standard.
People have frequently been saved from inevitable deaths because of initiatives like this.
The first is that you can reverse brain damage from dehydration by giving the body lack of fluids it needs to survive.
For example, if a person has mild dehydration, they will likely be able to recover with just some oral rehydration solution and a little rest.

One of the most common side effects of dehydration is headaches. In addition, research indicates that migraine attacks are among the main signs of dehydration.
This is probably because when you’re dehydrated, your body can’t produce enough saliva to moisten your mouth and throat.
Which means you have less saliva to keep your head cool.
This creates a climate where bacteria can grow faster, leading to worse congestion and more pain.
It’s also worth noting that hangover headaches often occur when you’re dehydrated because of other conditions—like an infection or dehydration-related kidney failure.
