Missing even 90 minutes of sleep for just 1 night can reduce your daytime alertness by as much as 32%. That’s enough to impair your memory, your thinking ability, and your safety on the job and on the road. One study even found that volunteers who stayed awake 6 hours past their normal bedtime just for one day performed as poorly on tests gauging attentiveness and reaction time as those who were legally drunk. In 2009 The National Sleep Foundation showed that around 1.9 million drivers had a car crash or near miss due to drowsiness the year before.
Why is Sleep So Important?
- It maintains a strong immune system. Sleep deprivation compromises immune function and makes you more vulnerable to disease.
- It slows aging. Too little sleep elevates levels of stress hormones and lowers levels of growth hormone, necessary for cell repair. In one study, young, healthy sleep-deprived subjects had the hormonal profiles of much older people.
- It prevents diabetes. Sleeplessness increases insulin resistance, a precursor to type 2 diabetes.
- It keeps you slim. When you’re sleep deprived, you have more of the appetite-stimulating hormone ghrelin in your blood and less appetite-curbing leptin, a combo that leaves you longing for junk food.
- It can make you happier. Insomniacs face a higher risk of depression, alcoholism, and suicide.
- Learning and memory. Sleep helps the brain commit new information to memory through a process called memory consolidation. In studies, people who’d slept after learning a task did better on tests later.
- Safety. Sleep debt contributes to a greater tendency to fall asleep during the daytime. These lapses may cause falls and mistakes such as medical errors, air traffic mishaps, and road accidents.
- Mood. Sleep loss may result in irritability, impatience, inability to concentrate, and moodiness. Too little sleep can also leave you too tired to do the things you like to do.
- Cardiovascular health. Serious sleep disorders have been linked to hypertension, increased stress hormone levels, and irregular heartbeat.
- Disease. Sleep deprivation alters immune function, including the activity of the body’s killer cells. Keeping up with sleep may also help fight cancer.
