Hello doctor, is it true that when you don’t sleep for around three days, you die? How is lack of sleep connected to diseases that lead to death? Stephen

Dear Stephen,
Whereas animal studies (specifically on rats) show death occurring after roughly 11 to 32 days of total sleep deprivation, there is no confirmed number of days after which sleep deprivation alone causes death in humans because ethics of research prevents scientists from researching the absolute fatal breaking point in humans.

Implications
Chronic sleep deprivation deteriorates how an individual coordinates their muscles, limbs, and overall body to accomplish a physical goal (motor performance), leading to enhanced accident risk and generally higher error rates, hence reduced work productivity.
Long term sleep restriction may lead to a reduced sense of sleepiness despite continuing reduction in cognitive performance capabilities.
•Sleep deprivation increases sleepiness, impairs mood states and emotional processing and contributes to
altered risk-taking and decision-making behaviour.

•Long-term sleep restriction may lead to a reduced sense of sleepiness despite continuing reductions incognitive performance capabilities.

•Important negative health outcome measures such as
weight gain, obesity, type 2 diabetes, cardiovascular disease, hypertension and inflammation have been
associated with insufficient sleep.

•Several immune-related transcripts and markers of infection are altered after sleep restriction, providing a possible pathophysiological basis for the elevated risk of falling sick after sleep loss.

•Insufficient sleep has been associated with elevated mortality, enhanced accident risk and a generally
increased incidence of errors.

Several immune-related transcripts and makers of infection are altered after sleep restriction, this explains why there is an elevated risk of falling sick after sleep loss.
