“Judgment is affected, memory is impaired, and there's deterioration in decision-making ability and eye-hand coordination,” Cralle says. You also tend to be more emotionally reactive, attention is decreased, hearing is impaired, and there is an increase in your risk of death from a fatal accident, she says.
Sleep is vital to the proper functioning of the body, and completely skipping a night of sleep can harm your thinking and cognition, your mood and emotions, and your physical well-being.
After going without sleep for 48 hours, a person's cognitive performance will worsen, and they will become very fatigued. At this point, the brain will start entering brief periods of complete unconsciousness, also known as microsleep. Microsleep occurs involuntarily and can last for several seconds.
After two days of no sleep, you can count on increased irritability, anxiety, foggy memory, and impaired thinking, says Hussam Al-Sharif, MD, a pulmonologist and sleep medicine specialist at the Mayo Clinic in Eau Claire, Wisconsin.
"Staying up all night just once doesn't mean you'll develop one of these health conditions, but engaging in sleep deprivation can encourage poor sleep habits, which, over time, could ultimately impact your overall health," says Dr. Ram.
It's best not to make pulling an all-nighter a regular activity because it may disrupt your circadian rhythm, lead to sleep problems, and increase your risk of developing chronic illnesses.
Beneath the surface, your body is aging too, and sleep loss can speed up the process. A study done by UCLA researchers discovered that just a single night of insufficient sleep can make an older adults' cells age quicker. This might not seem like a big deal, but it has the potential to bring on a lot of other diseases.
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.
Sleeping beyond the 90-minute cycle may mean you fall deeper into your sleep cycle and will find it much harder to wake up.

Anxiety, stress, and depression are some of the most common causes of chronic insomnia. Having difficulty sleeping can also make anxiety, stress, and depression symptoms worse. Other common emotional and psychological causes include anger, worry, grief, bipolar disorder, and trauma.
Moreover, brain scans of the participants who pulled all-nighters showed heightened activity in the mesolimbic pathway, a brain circuit driven by dopamine, a neurotransmitter that regulates positive feelings, motivation, sex drive, addiction, cravings and decision making.
Those who use meth can stay awake for several days without feeling like their body needs rest, which can lead to insomnia. Lack of REM sleep: Both serotonin and dopamine cannot be properly reabsorbed by the brain when someone uses meth.
Going 96 hours or more without sleep can be very dangerous for your body. Sleep is your body's way of recharging. Studies have shown that the longer time we spend without sleep, the more psychotic systems we begin to develop. This can range from simple visual misperceptions to complete sleep deprivation hallucinations.
“A power nap is a nap that's short — less than 30 minutes long,” says Safia Khan, MD, a specialist in sleep disorders and an assistant professor in the department of family and community medicine and the department of neurology at UT Southwestern Medical Center in Dallas.
