What Is Deep Sleep?

Deep sleep is what we need to feel refreshed in the morning. If our deep sleep is disrupted, we feel groggy in the morning. When we sleep, we go through 90-minute cycles alternating between REM and non-REM sleep. Deep sleep comes in the last non-REM cycle. Here is a breakdown of the stages.

  • Stage 1: The first stage of Non-REM sleep lasts several minutes as we begin to fall asleep. Our body functions slow down and brain waves slow, and our muscles start to relax.
  • Stage 2: The second stage of Non-REM sleep makes up about half of our total sleep cycle. Your body and brain continue to relax, your core temperature starts to drop, and your eye moments now stop.
  • Stage 3 & 4: The third and fourth stage is when we experience deep sleep. Our heartbeat, breathing, and brain waves will be at their slowest rate. In this stage, it is difficult to wake up even if there are loud noises. The third stage lasts between 45-90 minutes. As the night goes on, deep sleep stages become shorter.
  • Stage 5: In the fifth stage, after roughly 90 minutes of Non-REM sleep, we experience our first REM sleep stage. During this stage, a couple of things happen. Our eyes move rapidly. Our heart rate increases, and we breathe faster. Our limbs may become paralyzed. Also, since our brain activity increases, we experience dreams.


What Are The Benefits?

  • Increased glucose metabolism, which supports short term and long term memory and learning
  • Increased hormone secretion
  • Cell and Energy restoration
  • Increased blood supply for muscles
  • Enhanced growth and repair of muscle tissues and bones
  • Strengthened immune system


How Do You Know If You’re Getting Enough Of It?

An obvious sign that you are not getting enough is that you wake up feeling exhausted. If that’s the case, you have two options to track your sleep. One, a wearable device like a smartwatch, although this may not be reliable. Two, get work with a sleep center to get a polysomnography (PSG) test which measures body movements, brain waves, breathing rate, heart rate, and oxygen levels.

Tips On How To Increase Deep Sleep

There is plenty of general advice out there to get more deep sleep. Tips include:

  • Following a routine schedule.
  • Getting plenty of exercise during the day.
  • Avoiding caffeine before bed.

The most overlooked but most important factor that leads to deep sleep is temperature. Deep sleep requires a cooler body temperature.
