But if you're among the 14 percent of Americans who suffer from migraines, a new study out of Harvard University says you should avoid having too much caffeine.
In one small study, 93% of migraine patients were also prone to brain freeze, which has led researchers to suspect that the trigeminal nerve also plays a key role in migraines.
Users take a monthly shot that targets a molecule thought to play a role in migraines and has been shown in clinical trials to measurably reduce headache frequency for chronic sufferers.
Interestingly, 1 in 5 migraine sufferers report having a visual disturbance like a flash of light or zigzag lines in front of their vision before their migraine kicks in.
