A headache is one of the most common complaints, and yet they can be so easy to prevent. If you’re treading into migraine territory, those headaches can be debilitating, stealing precious time from you and rendering you incapable of functioning. Unfortunately, “headaches” can be a symptom for just about anything, so if you’re a chronic sufferer start by checking in with your doctor. There might be bigger issues at play.

Consider past injuries, such as neck trauma that’s causing a headache, and get a second opinion if your gut is telling you there’s a medical issue. Otherwise, consider these common causes of headaches and see if you can address the issue yourself. It might just take some habits changing to get the results you want:

1. Too Much Screen Time

The experts at HealthDay say kids are still getting too much screen time, and it’s likely that you’re even worse off. Staring at a screen without frequent breaks and blinking properly can easily cause a chronic headache. Chances are you’re working at a computer all day, and in between that time you’re watching television or checking out your smartphone. Give your eyes a break every 20 minutes, close your eyes for 30 seconds, and minimize your television habits.

3. Poor Nutrition

If you don’t feed your body properly and stay hydrated, it’ll start complaining and that can begin with a headache. Ditch the convenience foods, sip water throughout the day, and focus on nutritious eating. One of the first signs that your body isn’t getting what it wants is with a pounding headache.

Everyone needs different amounts of sleep, and if you’re not giving your body what it wants, it’ll let you know. A lack of sleep can mean an increased in diseases, but it can also mean a pesky headache that won’t go away. Make sure your sleep hygiene is on point, and you’ll see instant results.

Not all headaches are created equally, and they may be a sign of a more serious medical issue. Check in with your doctor and make sure there’s not an underlying problem.
