Other headache triggers involve a weak neck, bad posture, work conditions that are not ergonomic, eyestrain (especially due to bad lighting or squinting) or weak eyesight that has been neglected.

Congestion in the respiratory system is yet another common cause. Some athletes or exercise freaks also suffer from a sudden attack from over-exertion. Such physical causes are naturally offset by a regular yoga sadhana.

Sometimes the causes for a headache may be hidden. Bad eating habits, including skipping meals, can trigger headaches caused by plummeting blood sugar levels. Overeating and chronic constipation may be other causes.

Certain medications can also have an allergic reaction that sets off a pulsating pain in the head. Any unusual physical activity done suddenly may set off a headache, called exertional headache. Certain foods like cheese and MSG used in Chinese food are also known triggers in chronic cases.

In such cases being aware of the trigger may help avoid it. Involving a medical practitioner would help you locate the cause faster. Once conventional therapy has been started, you may consider complementing it with a regular yoga sadhana which powers the body against such attacks.

Shameem Akthar, yoga acharya trained with the Sivananda Yoga Vedanta Center, Kerala, leads you through five yogic practices that help relieve headaches.
