One of the most common causes of headaches is something that you can usually avoid as long as you drink enough water. A dehydration headache occurs when there is not enough fluid in the body. When there’s not enough fluid, it can cause the brain to shrink or contract. This then causes the brain to move away from the skull and cause a headache or migraine. After you rehydrate yourself, the brain will plump back up and the pain should subside. To avoid a dehydration headache, make sure you drink at least 64 ounces of water per day and more if you do strenuous exercise, sweat a lot, or drink caffeine or alcohol.
Some signs of dehydration include extreme thirst, confusion, dark-colored urine, reduced urination, fatigue, dry, sticky mouth, low blood pressure, increased heart rate, loss of skin elasticity, and dizziness. If you’re severely dehydrated, try drinking something with electrolytes while also decreasing activity and cooling yourself off if it’s hot.
Another common cause of headaches is hormonal changes. For instance, it’s common to experience headaches during certain periods of a menstrual cycle, as well as during pregnancy or menopause due to the drop in estrogen levels. Hormonal birth control can also cause headaches and migraines. If you take birth control, switching to a progesterone-only or non-hormonal type can help improve migraines. If you’re going through menopause, taking hormones might help. Talk to your physician to learn about the best option for you.
3. Lack of Sleep
Adults should sleep between 7 to 9 hours per night for the most benefits possible. When you don’t get enough sleep, it can trigger a headache or migraine. On the flip side, sleeping too much can also trigger a migraine or headache. To avoid headaches from not enough or too much sleep, stick to a consistent sleep schedule and take a nap when necessary.
