How much sleep do you need?
In healthy adults, about 13-to-23 percent of your sleep is deep sleep. So if you sleep for 8 hours a night, that’s roughly 62 to 110 minutes. However, as you get older, you require less deep sleep.
During deep sleep, a variety of functions take place in the mind and body:
- Memories are consolidated
- Learning and emotions process
- Physical recovery occurs
- Blood sugar levels and metabolism balance out
- The immune system is energized
- The brain detoxifies
Without deep sleep, these functions cannot take place, and the symptoms of sleep deprivation kick in.
What is REM sleep?
REM sleep is often referred to as stage 5, is when you are most likely to dream. Your first REM cycle of the night begins about 90 minutes after you fall asleep and reoccurs every 90 minutes. Your eyes move around quickly behind your eyelids, and your brainwaves look similar to those of someone awake. Your breathing, heart rate, and blood pressure rise to near-waking levels. Your arms and legs become temporarily paralyzed e to prevent you from physically acting out your dreams.
How much REM sleep should you get?
For most adults, during average healthy sleep cycles. REM takes up about 20-to-25 percent of sleep.
There is still a lot of progress that needs to be made to better understand sleep and its effect on our health. But what we already have states that sleep is necessary to develop to keep our body healthy. If you find that you are suffering from sleep deprivation, seek help, make lifestyle and environmental adjustments, and research medications and alternative therapies.
