5. Dehydration Headaches
It’s been long believed that people should get at least eight glasses of water per day if they want to be healthy – but have you thought about how many questions this brings up? For one, how large is the average glass – and what about someone who has a smaller stomach, or simply different needs to keep their body in good shape.
Now it’s agreed by most health professionals that the amount of water any one person needs for good health is down to everyone’s own body makeup – and it might be a little less or a little more than the recommended amount. Everyone knows, more or less, how much that should be.
Headaches can easily be a symptom of dehydration – common if you haven’t had anything to drink for a while, or if you’ve just spent a considerable amount of effort expanding fluid through your sweat. Frequent urination or vomiting can also lead to dehydration, so take care if you are recovering from stomach flu.
Usually, drinking some water or juice to replenish lost fluid is enough to take care of this type of headache.
