These are some simple lifestyle changes that can make a huge impact on headaches.  Lifestyle changes can address some common root causes of headaches, such as bad posture and stress.

Aerobic exercise  several times a week  has been shown  to decrease the intensity of headaches — but maybe stay away from high-intensity workouts. For a few subjects, it also decreased the frequency.

A healthy diet  is also important to prevent headaches. Many headache sufferers identify food triggers, such as food additives, wheat, dairy, an excess or lack of sugar . A healthy diet of whole foods should avoid chemical preservatives and inflammatory food agents.

Chiropractic care  is essential for headache prevention since spinal misalignment can contribute to the majority of headaches. Studies show  that going to a good chiropractor  can reduce  the frequency, duration, intensity of headaches — as well as medication reliance.

Excessive caffeine consumption  can trigger  headaches on the daily. This means six or more cups of coffee a day. However, periodic caffeine can help alleviate headaches.

Caffeine withdrawal   also leads to headaches. Avoid cutting caffeine cold turkey — either from coffee, soda, tea, pills, etc.

A full night’s sleep  can do wonders for your headaches. A full night’s sleep  relieves stress  and can lead to fewer migraines and tension headaches.

Stress-relieving practices  can reduce the frequency of tension headaches, which are triggered by bad posture and stress.  Meditation , yoga, looking away from the computer screen, and  being outside  have all been linked with a decrease in stress.

A  research-backed practice  that requires some commitment is  thermal biofeedback , learning to increase the skin temperature of your fingers. This involves hours of training and at-home sessions. But many studies confirm thermal biofeedback may be comparable to pharmaceuticals, without all those pesky side effects.
