You don’t get enough sleep
If you can’t sleep, it may be a sign that you suffer from insomnia, or other severe diseases, such as depression. You should talk to your doctor about this problem and try to be more active during the day. Maybe your diet should be changed as well.
According to Nate Favini, MD, chief medical lead at primary care company Forward, “for most people, trouble sleeping is caused by lack of physical activity during the day or too much caffeine, but it can be a sign of a more concerning issue. Depression, anxiety, and thyroid problems can all impact sleep. If you have trouble sleeping for a long period of time, discuss it with your doctor.”
