Strange Causes of Headaches That Have Nothing to Do With Dehydration
17. Noise Pollution: The Headache You Can’t Hear

We know that loud noises can cause headaches, but did you know that even low-level background noise can do the same? Constant exposure to traffic, construction sounds, or even buzzing electronics can lead to sensory overload, increasing stress hormones and making you more prone to headaches. Investing in noise-canceling headphones, using white noise machines, or spending time in quiet, nature-filled environments can help reduce the impact of noise pollution on your health.
18. Caffeine Overload (or Withdrawal): A Double-Edged Sword

Caffeine can be both a headache reliever and a headache trigger. For some, it provides relief by constricting blood vessels and blocking pain signals. But consuming too much caffeine can lead to dependency, and skipping your daily fix can cause withdrawal headaches. If you're a regular coffee drinker and experience headaches when you miss a cup, consider gradually reducing caffeine intake to see if it makes a difference in your headache frequency.
