I'm always harping on about sleep and for good reason - it's when our body regenerates.
And with the busy culture we keep forcing ourselves to live in, there's a thought process that sleep is time we could be doing something wrong.
Outrageous I tell you!
This piece on sleep is taken from an article by Dr. Matthew Walker.
- There is REM (rapid eye movement) sleep and non-REM sleep
- There are 4 stages of non-REM sleep and it's in stages 3 and 4 where body replenishment takes place
- These are also the stages of sleep that 1 half of your brain will resist going into when sleeping in foreign environments (hotel room, camping etc)
- We are a dark deprived society and this lack of darkness is destroying our quality of sleep
- Incandescent light bulbs suppress melatonin and phone/computer screens suppress it even further
- 1 hour of phone use will decrease melatonin production by about 3 hours
- You're peak melatonin levels will also be about 50% less than they should be
Midnight should actually be the middle of your sleep night
- The shorter your sleep on average the shorter your life span
- 1 week of 6 hours of sleep per night results in 711 genes being distorted in their actoivity
- Half of those genes saw an increase in activity but they were the one's related to tumors, chronic inflammation, stress and cardiovascular disease
- The "good half of your genes that are being suppressed are those are related to immune response and than you can become immune deficient
- Resident doctors working 30 hours shifts are 460% more likely to make a diagnostic error in the intensive care unit relative to 16 hour shifts
- If your surgeon has had 6 hours of sleep or less then they have a 170% increased risk of major error so ask them how much sleep they've had
- 1 in 5 resident doctors will make an error due to lack of sleep and 1 in 20 will kill a patient due to a fatigues related error
Surely that will make you prioritise sleep now?
