9. Medication
Many common medications can cause sleep problems, too. These include prescription medications used to treat depression, anxiety, and ADHD. Steroids, beta blockers, and thyroid medication are also known to interfere with sleep. And some over-the-counter medications (like decongestants) can also cause insomnia.
10. Eating before bed
There’s some evidence that eating in the hour before bedtime can interfere with your sleep. This may be especially true if you eat a large amount of food, or consume spicy foods. If you do get hungry in the evening before bedtime, a small, simple snack may be the best choice, like a small portion of oatmeal or yogurt, or a piece of fruit.
