Headaches are a very common pain that many experience. Most headaches go away with little to no treatment and are usually not a sign of anything serious. The two most common types of headaches are migraine headaches and tension headaches. Migraines are often brought on by extremely sensitive nerve endings in the brain. Genetics are often a major cause for migraine headaches, as most individuals who experience migraines have family members with the same condition. Tension headaches are a result of tense head and neck muscles. Causes of tension headaches vary from person to person, however they are most commonly triggered by: - Stress - Illness - Hormones - Weather changes - Diet (eg. processed food and alcohol) - Caffeine withdrawal - Lack of sleep - External surroundings (eg.lights and smells)
