1Dehydration

Water intake is one of the most important factors for our health. Dehydration can lead to headaches in many people. Scientists have not found out the precise association, but they believe it has something to do with how blood flow decreases when you do not take in sufficient fluids. A low blood volume would result in reduced oxygen to the brain and trigger the symptom. Depending on your gender, age, and daily physical activities, the recommended fluid intake can vary. In general, a typical adult should drink more or less 2 liters every day. In addition to plain water, you can also consume herbal tea and eat fruits or veggies with high water content like tomatoes, watermelon, or celery. [1]
