This article arrived in my inbox the other day all about sleep.
One of my favourite things about my FitBit is the sleep app part of it. I love how it shows you not only how long you slept for, but what different types of sleep cycles you went through each given night.
You usually move from light sleep to deep sleep, back to light then onto REM.
You can be awake between 10 - 30 times per night, but most are so short you will not remember them.
REM typically occurs later at night and has been shown to improve your mood and memory. During this stage your dreams are more vivid, your heartbeat is elevated and your breathing faster.
Light sleep is very important, it makes up most of your night and promotes mental and physical restoration.
Deep sleep helps with physical recovery and helps with memory and learning. If you wake up feeling refreshed you probably had a good deep sleep.
On an average night I should be awake 12% to 24% of the time. In REM 15% to 25% of the time. Light sleep 40% to 60% of the time and deep sleep 8% to 16% of the time.
Everyone is different. Me personally, I do best if I can sleep 9 hours per night. If I could sleep longer I could and I would!! I need my sleep. I average around 8 hours sleep per night.
The other night for instance these were my numbers:
REM : 18%
Light Sleep: 56%
Deep Sleep: 17%
I also tend to fall into a deep sleep right away as per my FitBit.
Are you a good sleeper?
