What is healthy sleep?
A good night’s sleep has become something of an indulgence in today’s fast-paced world. The need to get enough sleep dropped down on our list of goals behind jobs, chores, social time, and entertainment.
Sleep shouldn’t be a luxury, though. It’s as important as food and water for your physical and mental health.
A relatively recent research area is the body’s need for sleep. We know it is important to sleep in order to:
- Maintain essential functions in the body
- Restore energy
- Regenerate muscle tissue
- Help your brain process information
For healthy adult individuals with normal sleep, the appropriate sleep duration is 7 to 9 hours.
What is light and deep sleep?
There are several sleep stages you go through every night, the most important ones being Light and Deep sleep.
Stage 1 marks the start of the light sleep phase when you drift from being awake to being asleep. This is a light, NREM sleep, which doesn’t last a long time. As you transition into stage 2, you can begin to relax and dream, but may also twitch. Your heartbeat and breathing slow down, and your muscles relax. The temperature of your body decreases and your brain waves are less present.
Stage 3 is the period of deep sleep that you need to feel refreshed in the morning.
Deep sleep starts in stage 3. Your breathing, heartbeat, body temperature, and brain waves hit their lowest levels during deep sleep. Your muscles are extremely relaxed, and it is the hardest phase to wake up from. Stage 4 is known as the healing stage, where essential hormones are released to do their job when tissue growth and repair takes place.
How much deep sleep do I need?
In healthy adults, deep sleep should account for around 13 to 23 percent of sleep. If you’re sleeping 8 hours a night, it’s about 60 to 120 minutes.
A variety of processes take place in the mind and body during deep sleep:
- Your memories merge
- Physical recovery occurs
- Blood sugar level stabilizes
- Metabolism slows down
- Brain detoxifies
These processes do not take place without deep sleep, so if you’re not getting enough deep sleep the signs of sleep deprivation kick in.
How to increase deep sleep?
Sleep meditations are the most common remedy for sleep problems. They help your body transition to sleep easier and raise your chances of entering the deep sleep stage.
