Nice read this month.
I'm particularly interested in sleep in the context of healthy behaviour. People often list diet and exercise when they think about behaviours they can modify to improve their health, but I doubt many people think about sleep.
I'm not sure it's as important as diet and exercise, but making improvements in sleeping habits is something most people are probably not aware of, but can have a significant impact of health and daily functioning, as anyone who has been sleep deprived can testify.
For those with institutional access, this recent article sums up the research nicely.
