Sleep Deprivation Can Be Deadly. Here’s What Sleeping Less Than 7 Hours Per Night Does to Your Body And Brain
It’s not pretty.

About a third of US adults don’t get enough sleep.
And sleep deprivation has serious consequences for your brain and body.
Many people think they can get by on less than seven to nine hours a night – the amount of sleep doctors recommend for most adults – or say they need to sleep less because of work or family obligations.
That prompted Arianna Huffington to post an open letter to Musk about his sleep schedule, telling him that he was “demonstrating a wildly outdated, anti-scientific and horribly inefficient way of using human energy.”
Musk posted his response on Twitter at 2:30 a.m. ET. “I just got home from the factory,” he said. “You think this is an option. It is not.”
Musk seems to understand that working 120-hour weeks is harmful. As Matthew Walker, a neuroscientist who’s an expert on sleep, previously told Business Insider, “The shorter your sleep, the shorter your life.”
Most adults need seven to nine hours of sleep, and kids have to get even more, though needs do vary from person to person. Some incredibly rare people can actually get by on a few hours of sleep per night, while others on the opposite end of the spectrum are sometimes called “long sleepers” because they need 11 hours nightly.
But regardless of your body’s clock, a lack of sleep will cause your physical and mental health to suffer.
Here are 30 health consequences of sleep deprivation.
Sleep deprivation is linked to a higher risk for certain cancers.
Skin doesn’t heal as well from damage when you are tired, leading to skin ageing.
Poor sleep quality is strongly correlated with chronic skin problems, according to research from the University of Wisconsin. Studies have also found that when skin is damaged by the sun or other factors, it doesn’t heal as well in poor sleepers, so those people wind up showing more signs of skin ageing.
Tired people have a harder time controlling their impulses, potentially leading to unhealthy behaviour and weight gain.
People who don’t get enough sleep have a harder time resisting high-calorie foods, more cravings for unhealthy meals, and difficulty controlling their impulses. Researchers think hormonal imbalances that result from sleep deprivation are responsible for this, since those imbalances are linked to a high body mass index and obesity.
People feel lonelier after sleepless nights — and being lonely makes it harder to sleep well.
Researchers have found that sleep-deprived young adults are less likely to connect socially with other people, and that people who report poor sleep also tend to say they’re lonelier. To make things worse, people who feel lonely don’t tend to sleep as well, which can lead to a sort of vicious cycle.
Being sleepy makes it harder to learn and disrupts short-term memory.
Sleepiness has long been a problem for students. Delaying school start times an hour for middle-school kids has been found to significantly increase standardised test scores, and it may have an even bigger effect on teens, who naturally tend to be night owls.
But it’s not just kids – sleep deprivation also wrecks adults’ short-term memory. Several studies have found that sleep-deprived adults have more difficulty remembering words they have learned and have a harder time improving newly learned skills.
