For severe dehydration, you may need to slowly lie down and drink more fluids. In extreme cases, intravenous IV rehydration may be necessary.

Drinking enough water does more than just prevent dehydration headaches - it can also prevent migraines. While we do not know exactly what causes a migraine, we do know that dehydration is a known trigger for migraine headaches.

Hot weather and high temperatures also put you at risk. If you have a headache and any of the these things describe your current situation, dehydration is the likely culprit.

When you become dehydrated your brain tissue loses water causing your brain to shrink and pull away from the skull. This triggers the pain receptors surrounding the brain, giving you a headache. Dehydration also causes your blood volume to drop which in turn lowers the flow of blood and oxygen to the brain. In response the blood vessels in the brain dilate leading to swelling and inflammation, worsening the headache.

Dehydration headaches are caused by an inadequate amount of fluid for the body to function correctly. Physical activity causes sweating and water loss. If you are already dehydrated you should minimise physical activity and focus on fluid intake.

Frequent breaks and adequate rest are recommended until your symptoms subside. Our bodies can only absorb a small amount of water at at time and drinking to much too fast will only leave you bloated and uncomfortable with a stomach full of water.

Instead go for small amounts frequently, say mls every mins, until symptoms subside. Electrolytes are also lost through sweat and play an essential role in water retention. Failure to replace lost electrolytes will lead to difficulties rehydrating. Add some electrolyte powder to your water for fast electrolyte replenishment.

Headaches caused by dehydration will usually subside once adequate water has returned to the brain. However, this can take several hours of active fluid replacement.

Together with the right balance of electrolytes, water is therefore vital for our bodies to function properly. Daily activities such as sweating and urinating cause the body to lose water. Usually, the amount of fluid lost is easily balanced through drinking or eating foods that contain lots of water.

However, sometimes the body loses water faster than it can be replenished. When this happens, the body can become dehydrated. Dehydration headaches occur secondary to or as a complication of dehydration. Mild to moderate dehydration can cause headaches that can range from being relatively mild to severe headaches such as migraines. Dehydration headaches may be caused by the brain temporarily contracting or shrinking due to the fluid loss. This action of the brain pulling away from the skull can potentially cause the pain of a dehydration headache.

The volume of plasma in the blood vessels of the brain may also decrease since plasma has a high water component. Dehydration headaches are relieved once the body is rehydrated and the brain returns to its normal size and state.
