Hydrate, hydrate, hydrate!
Dehydration is the easiest way to get a headache, and it’s especially problematic for those prone to migraines (which happens to be a huge number of people). In fact, migraines are the most disabling neurological disease for people aged below 50.
According to a recent review of studies, severe headaches and migraines affect 1 in 10 men and more than 1 in 5 women. The condition is manifested by rounds of moderate to severe pain around the head or one eye, sensitivity to smell, sound, and light, and even nausea and vomiting. Make sure to always stay hydrated.
