10 Heat Rash Symptoms

Symptom #6: Headache
Rise in body temperature and dehydration due to high environmental temperatures can lead to headaches. Heat can cause blood vessels in the head to constrict in order to prevent over heating of the brain. The shunting of blood away from the brain could cause headaches but it is more likely due to dehydration.
Increasing your fluid intake can help reduce headache incidences. Keep a glass or a bottle of water with you and keep sipping on it throughout the day. You can also increase your fluid intake by taking fruit juices. Also eat light meals that are easily digested and low in fat and sodium. Wearing sunglasses or carrying an umbrella can keep out excess light from your eyes and face and thereby reduce headache instances.
