Prevention of dehydration headaches begins by ensuring that the person is drinking enough fluids and avoiding areas where they are likely to lose fluids (such as during exercise). If symptoms do develop, drinking cool liquids such as water or fruit juice will help relieve the pain. Ibuprofen or acetaminophen may also be effective in relieving pain. If dehydration is severe, medical attention may be required.

Also, avoid hot and spicy foods and beverages if you’re feeling headachey from dehydration. These foods can cause your body to release more fluid in an effort to cool down.

Eat cucumbers. Cucumbers are a good source of hydration and contain anti-inflammatory properties which can help reduce the pain. Some people also find that eating cucumbers helps to speed up the reclamation process after suffering from a dehydration headache.

Eat bananas. Bananas are another good source of hydration and contain potassium which can help improve nerve function and reduce inflammation. Additionally, bananas are high in fiber which can help keep you feeling full longer so you don’t overeat or drink too much fluids in an attempt to alleviate your pain.

Grapefruit: Grapefruit is another fruit that’s packed with nutrients that can help relieve symptoms of dehydration such as headache and neck pain. One study found that grapefruit extract was effective in reducing brain swelling in patients with mild traumatic brain injury (MTBI). Additionally, grapefruit contains pectin, which has anti-inflammatory properties.

Cranberry Juice: Cranberry juice is packed full of antioxidants, including quercetin, which has been shown to help relief symptoms of dehydration such as headache and neck pain. It’s also high in vitamin C, which helps fight against cell damage and inflammation.


Dehydration can cause your brain and other organs to work harder than they should, leading to pain and inflammation. Make sure you drink plenty of fluids (including water, unsweetened tea, broth, vegetable juice and sports drinks). And as always, consult your doctor if the headache persists or worsens.
