The BBC recently referenced a PLoS Medicine study describing the health problems that can arise from lack of sleep (via SlashDot):
- Those who slept five hours or less around the age of 50 had a 30% greater risk of multiple ailments than those who slept seven hours
- Shorter sleep at 50 was also associated with a higher risk of death during the study period, mainly linked to the increased risk of chronic disease
We can’t be vigilant with an eye on our goals 24 hours a day. We’re human and we need sleep.
