Headaches are one of the most common ailments affecting people. They can range from mild to extremely painful, and can be caused by a variety of factors. Identifying the cause of your headache is crucial in finding an effective treatment.

Here are the most common causes of headaches:.

Stress

Stress is a leading cause of headaches. It can be caused by work, family, financial issues or any other source of tension. The best way to treat stress-induced headaches is to find effective ways of managing stress.

Dehydration

Dehydration is another common cause of headaches. It is important to drink enough water throughout the day to avoid becoming dehydrated. This is especially true during hot weather or when exercising.

Eye strain

Eye strain can cause headaches, particularly if you spend a lot of time staring at a computer screen or reading. Taking regular breaks to rest your eyes can help reduce the likelihood of developing a headache.

Sinusitis

Sinusitis is an inflammation of the sinuses and can cause headaches. Symptoms of sinusitis include pain and pressure around the eyes, forehead or cheeks. Treatment for sinusitis may involve prescribed medication and/or nasal irrigation.

Medications

Some medications, including over-the-counter pain relief medicines, can cause headaches. If you suspect that your headache is caused by a medication, speak to your doctor about finding an alternative.

Concussion

Head injuries, such as a concussion, can cause headaches. These headaches may range from mild to severe and may lead to other symptoms such as dizziness, nausea or vomiting.

If you have suffered a head injury and develop a headache, seek medical attention immediately.

Allergies

Allergies can cause headaches, particularly if there is sinus congestion. Avoiding exposure to allergens and using prescribed medications can help reduce the incidence of headaches caused by allergies.

Caffeine withdrawal

Caffeine is a stimulant that is commonly found in tea, coffee, cola, and some medications. If you regularly consume caffeine and then suddenly stop, it can cause withdrawal symptoms, including headaches.

Reducing your caffeine intake gradually can help avoid these symptoms.

Migraines

Migraines are a common type of headache that can be debilitating. Symptoms of migraines may include a throbbing pain on one side of the head, sensitivity to light and sound, and nausea.

If you suffer from migraines, your doctor may prescribe medication to manage your symptoms.
