Taking care of your health is one of the most important things you can do for yourself. Baylor College of Medicine experts have plenty of tips to help you stay healthy. This month’s Health Hint is on staving off headaches in the heat.

When the body becomes dehydrated it is believed to trigger a headache due to narrowing blood vessels as the body loses water and electrolytes. When a person is dehydrated, they are more likely to suffer from heat stroke, and a headache is sometimes a symptom of that, among other signs such as high body temperature, nausea and rapid breathing and heartbeat.

If you are already prone to headaches, such as migraines, this could be a trigger. One way to try to prevent this type of headache is by drinking plenty of water when you are spending the day outside and taking a break from activity.”
