Headache triggers
Migraines or headaches can occur without warning, however there are a few things that may increase your chances of having a headache:
Eyestrain
Tired eyes from looking at a screen or even reading for a long time can lead to eyestrain. This can be a cause of tension headaches.
Some people may use blue-light blocking glasses especially if most of their day is spent working on a computer. While studies vary, Dr. Houghton encourages people to use them if they find them helpful. Her No. 1 tip for preventing eyestrain is to move your gaze regularly.
“For every 30 to 60 minutes of sustained use of a computer or looking at a screen, take three to five minutes of visual rest,” says Dr. Houghton. “Go outside if you can or look out a window at the horizon.”
Dehydration
If you’re dehydrated and haven’t eaten enough, that’s a recipe for a headache. Dr. Houghton suggests drinking electrolytes daily. Without them, it’s common to end up with a headache. Electrolytes may not be as exciting as french fries, but they are more effective.
Nitrites
Some research suggests that foods containing nitrites like aged cheeses and processed meats may be migraine triggers. Check out our tips on how to eat better and “un-process” your diet.
Too much caffeine
While some studies show that caffeine can be helpful to treat headaches, too much of it may increase the number of headaches you have, Dr. Houghton says. Limit your caffeine to 200 milligrams a day (about one or two drinks) and avoid drinking caffeinated beverages after 2 p.m.
