Are you getting enough sleep? If not, eventually you will crash and burn (heart disease, decreased mental acuity, and reduced longevity; to name a few). Some people say that they only need 5 or 6 hours of sleep. Wrong. Actually, there really is something wrong if you can’t sleep the full required amount. So if you care about your health (some people don’t), check out the requirements: https://sleepfoundation.org/media-center/press-release/national-sleep-foundation-recommends-new-sleep-times
The keys to good sleep are nutrition, regular exercise, and good mental health. Also, only use your bedroom for sleeping (i.e. NO TV IN THE BEDROOM, sit up in a chair to read, etc.).
As you age and your hormone levels start to drop, the ability to fall asleep quickly and stay asleep is impacted. In this case, you can try melatonin. Start with the lowest dose of 1 mg 30-60 min. before going to bed. Give it about a week or so. If that doesn’t work, go up to 2 mg. The intake range is 1-5 mg. Everyone is different so don’t compare yourself with someone else.
When it comes to older people, the best results showed dosages from 2 to 3 mg taken 30 minutes before bedtime. These quantities do not cause overdose symptoms or side effects, significantly improve the quality of sleep, and help maintain alertness during the next day.
