From microsleeps to hallucinations to increased risks of potentially fatal issues such as heart attacks and strokes, a lack of sleep can cause severe bodily harm. For some people, just missing a few hours of sleep can cause a slew of problems, from a higher risk of diabetes and obesity to depression and drowsy driving.
And not just chronic lack of sleep, but a single night of lost sleep. While many people may have heard that sleep deprivation can affect things like metabolism and memory, research is also showing that it can strongly affect anxiety, Alzheimer's risk, and even chronic health at the level of our genes.
Staying up all night should never be thought of as positive or beneficial and should be avoided. Even in circumstances when pulling an all-nighter seems like it could help, such as to give you extra time to study or work, it's still typically a bad idea.

Conclusion. Resting your eyes is a good way to relax your body and replenish your eyes before it needs to take on more tasks, but it is in no way a substitute for sleep. Your body needs the replenishing benefits of sleep to function properly and restore itself.
To minimize sleep debt, regularly get the length of sleep you need to feel rested when you awaken. If you have built up sleep debt, allow extra time for sleep: go to bed early. You sleep more deeply when you are sleep deprived, so you do not need to “pay back” hour for hour the lost sleep.
We do not recommend sleeping for only one hour at night. Some research suggests that lost sleep can take years off your life and that you may not be able to catch up on the lost hours of rest. This is because consistent sleep deprivation can cause a myriad of chronic health issues in people over time.
Even one night of sleep deprivation affects how you view and select which foods to eat. Sleep deprivation impacts our brains in a way that prompts us to feel more rewarded by less healthy food and engage in higher calorie consumption, which is likely why insomnia and obesity are linked.
Sleep deficiency can lead to physical and mental health problems, injuries, loss of productivity, and even a greater likelihood of death.
A 20-minute nap will sharpen your attention and motor skills. A 90-minute one may improve your creative thinking. But naps between 20 and 90 minutes (or your own personal sweet spot) can leave you more groggy than when you started. Set an alarm.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain. Elon Musk, CEO of Tesla, speaks with CNBC on May 16th, 2023. Elon Musk says his days of trying to sleep less and work more are over — at least, relatively speaking.

Sleep feels good because when we rest, our bodies produce melatonin, which controls our sleep patterns. Our melatonin levels increase at bedtime, making us feel tired. Melatonin, secreted by the pineal gland, makes us feel cozy and relaxed, allowing our bodies to get the time off they need at the end of each day.
While making a habit of spending the day in bed or on the couch is not good for anyone, using it as a well-placed conscious tool for your emotional and mental well-being is absolutely ok. As a matter of fact, it's an investment in your health.

Sleeping beyond the 90-minute cycle may mean you fall deeper into your sleep cycle and will find it much harder to wake up.

When should I go to ER? Sleep deprivation isn't a condition that causes immediate, life-threatening problems, so it doesn't need emergency treatment. However, it can raise the risk of heart attack and stroke, both of which are emergency conditions that need immediate medical care.
