 One in 10 people are estimated to have chronic insomnia. The criteria for that is when someone takes more than 30 minutes to fall asleep or fall back asleep three or more times a week for three months or more. Does that sound like you? And if so, what should you do? Well, start by identifying why you can't sleep in the first place. Stress, anxiety, depression. It's going to be really hard to solve your insomnia problem without addressing the root cause first.
