Finally, good sleep hygiene is more important than anything else in preventing insomnia. Keeping regular sleep hours and about 30 minutes of daily aerobic exercises (like jogging or walking) will help a lot. Above all, you’re advised to avoid checking your smartphone, browsing the web or watching YouTube videos before bed; the light from the screens arouses your brain and prevents the release of melatonin, the hormone that helps you sleep. I hope you could end the painful sleepless nights with these healthy, regular habits.
