However, a closer look reveals that the pressure on the spine is at its lowest when we are lying in the supine position (it is under eight times less pressure than when we're sitting). It promotes most complete muscle relaxation, stress-relief and slower heartbeat.

A single night of poor or diminished sleep can lead to short-term effects, such as daytime tiredness and irritability. However, a frequent or consistent lack of sleep may increase the risk of developing longer-term, or chronic, health issues.

The best time to go to sleep and wake up will vary from person to person. In general, though, people should aim to fall asleep a few hours after dark and wake up within the first hours of sunlight in the morning, where possible.

The Best Time to Sleep Is Between 8 p.m. and Midnight

To align our sleep schedules with our body's natural cycles (our circadian rhythms), adults should go to bed when it's dark out, after 8 p.m. We also get deeper, more restorative sleep when our sleep time begins before midnight.
