A dehydration headache typically occurs if an individual does not drink sufficient water.
What are the indications?
A dehydration headache tends to vary from each individual but have symptoms that strikingly resemble other common types of headaches. In most cases, it feels the same as a feeling as a hangover that is often felt as a pulsating pain on both sides of the head that is aggravated by physical activity.
The headache becomes worse when moving the head, bending down or walking around. In most cases, relief is achieved within 30 minutes up to 3 hours of drinking water.
In one study involving those with chronic migraine, most consider dehydration as a trigger.
The usual signs of a migraine vary but might include:
- Nausea
- Intense pain on one side of the head
- Visual aura
Commonly used remedies for a dehydration headache
Drinking water
Initially, provide an individual with water as soon as possible. In most cases, a dehydration headache settles within 3 hours of drinking. Take note that 1-2 glasses of water are enough.
Remember that drinking rapidly can cause a dehydrated individual to vomit. It is recommended to take steady, slow sips.
Electrolyte drinks
Even though plain water is enough, beverages such as Pedialyte can provide an added boost of electrolytes.
Since dehydration disrupts the balance of electrolytes in the body, it is vital to restore the levels with low-sugar sports drinks.
Over-the-counter pain medications
In case a dehydration headache does not seem to improve after drinking water, an over-the-counter pain medication can be taken such as aspirin, ibuprofen or acetaminophen.
Cold compress
If the head is pounding, an ice pack can be used. Apply the ice pack on the head and rest in a quiet and dark place.
