Sleep more.

Easy to say, not always easy to do.

Negative thoughts get processed by one part of the brain (the amygdala, to be precise) and positive thoughts are processed by a separate part of the brain (hippocampus).  But when we become sleep deprived, the hippocampus takes the brunt and we focus on negative thoughts instead of happy ones.

In one experiment outlined in the book Nature Shock sleep deprived college students tested could remember 81% of words with negative connotations (like “cancer”) but only 31% of words that were positive or neutral.

Other studies show we overreact to negative emotions and fear when we need more sleep.

Sleep is one tough project, but here are some things that I would like to share that have helped me tremendously. 

• Sleep with an app.  My wife discovered that the new Philadelphia Eagles coach Chip Kelly told his players to download an app called Lark and buy the watchband that they would wear to clock their sleep every night.  It communicates by Bluetooth and reports on the quality of sleep, duration, disturbances and gives hints on how to improve it.
• Sleep 7-8 Hours nightly.  I refused.  Said I couldn’t do it until I had to face that app every morning and slowly but surely started averaging sleep in the healthy range.  There is no getting around it, we humans all need 7-8 hours of sleep a night no matter how we say we can get by without it.
• Wake up no more than 10 times a night.  As Lark teaches, if you awaken more than 10 times nightly – even without being aware of it – you may need to see a doctor about sleep apnea, a major disruptor of good healthy sleeping.

I have no financial interest in Lark and there are certainly lots of other alternatives out there, but one thing is for sure.  If we take a methodical, positive approach to improving our sleep, it can be the best happiness pill in the world.

If you decide to focus on sleep, I’d love to know your experiences.  Good luck – Jerry
