Lack of sleep can lead to poor cognitive function, increased inflammation, and reduced immune function. If sleep deprivation continues, it may increase your risk for chronic disease.
In general, there are five stages of sleep deprivation. The stages are usually divided into hour or hour increments. The symptoms usually get worse the longer you stay awake. The symptoms of sleep deprivation tend to get worse in each stage. According to the Centers for Disease Control and Prevention CDC , hour sleep deprivation is the same as having a blood alcohol concentration of 0.
When you miss 36 hours of sleep, your symptoms become more intense. You may start to have microsleeps , or brief periods of sleep, without realizing it.
A microsleep usually lasts up to 30 seconds. Different parts of your brain will have a hard time communicating with each other. This severely impairs your cognitive performance, causing symptoms like:.
Missing sleep for 48 hours is known as extreme sleep deprivation. You might even begin to hallucinate. After 3 days of sleep loss, your urge to sleep will get worse. You may experience more frequent, longer microsleeps.
The sleep deprivation will significantly impair your perception. Your hallucinations might become more complex. You may also have:. After 4 days, your perception of reality will be severely distorted. Your urge for sleep will also feel unbearable. You can start by going to bed early rather than sleeping in late. This will help your body get back on schedule. It can take days or weeks to recover from a bout of sleep deprivation.
Just 1 hour of sleep loss requires 4 days to recover. After two nights of missed sleep, most people have difficulty staying awake. They might experience periods of light sleep that can last up to 30 seconds. Microsleeps happen involuntarily. After a microsleep, you might feel confused or disoriented.
Staying awake for 48 hours also disrupts the immune system. Inflammatory markers, which help your body prevent and target illnesses, start to circulate at increased levels. Some research has shown that natural killer NK cell activity decreases with sleep deprivation. NK cells respond to immediate threats to your health, such as viruses or bacteria. After 72 hours without sleep, most people experience an overwhelming urge to sleep.
Many are unable to stay awake on their own. Going three days without sleep profoundly limits the ability to think, especially executive functions such as multitasking, remembering details, and paying attention. This level of sleep deprivation can make it difficult to see even simple tasks through to completion.
Emotions are also affected. People who have undergone this level of sleep deprivation may be easily irritated.
They may experience a depressed mood, anxiety, or paranoia. In one study , participants with 30 hours of sleep deprivation had difficulty recognizing angry and happy facial expressions. Finally, several days of sleep deprivation can significantly alter perception.
Illusions are also common. Sleep deprivation can change both your appetite and the types of foods you crave. Studies suggest that sleep deprivation is associated with both an increased appetite and an increased desire for foods associated with weight gain. However, consuming empty calories can ultimately leave you more tired.
Eating well may offset some of the effects of sleep deprivation, but only to an extent. Since your body is conserving energy, opt for lean, protein-rich foods , such as nuts and nut butters, cottage cheese, or tofu.
Avoid fatty proteins, such as steak or cheese. These will make you sleepier. Chronic partial sleep deprivation is associated with both short-term health risks and long-term complications. In the long term, not getting enough sleep can reduce immune functioning and increase your risk of certain health conditions. These include:.
