What Causes Headaches?
Headaches can develop for many reasons. Some are related to lifestyle factors, while others may be linked to medical conditions.
Common causes of headaches include:
Stress and tension
Stress is one of the most common triggers of tension headaches, leading to tight muscles in the head and neck.
Dehydration
Not drinking enough water can lead to headaches and worsen symptoms throughout the day.
Lack of sleep
Poor sleep or changes in sleep patterns can trigger both tension headaches and migraines.
Illness or infection
Colds, flu or sinus infections may cause sinus headaches due to pressure in the face and forehead.
Migraine triggers
Certain foods, hormonal changes, bright lights or strong smells can trigger migraine headaches in some people.
Eye strain
Spending long periods looking at screens can lead to headaches and discomfort.
Caffeine use or withdrawal
Too much caffeine or suddenly stopping caffeine can cause headaches.
Underlying medical conditions
In some cases, headaches may be linked to conditions such as high blood pressure, head injury or neurological disorders.
Sometimes, headaches may have more than one trigger.
