Sleep deficiency is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression. Sleep deficiency is also linked to a higher chance of injury in adults, teens, and children.
An ongoing lack of sleep has been closely associated with hypertension, heart attacks and strokes, obesity, diabetes, depression and anxiety, decreased brain function, memory loss, weakened immune system, lower fertility rates and psychiatric disorders.
The bottom line. The first stage of sleep deprivation occurs within 24 hours of missed sleep. Most people can tolerate this level of sleep loss.
Sleep deprivation increases your risk for health problems (even ones you have never experienced), such as disturbed mood, gastrointestinal symptoms (abdominal pain, gas, diarrhea, constipation, nausea, vomiting), headaches and joint pain, blood sugar and insulin system disruption, high blood pressure, seizures, and ...
Although not terribly common, lightheadedness can also be a consequence of sleep deprivation. Often, headaches and tension are found to increase after poor sleep; occasionally this may be accompanied by feelings of dizziness and light-headedness.
If your school or work schedule requires you to be up between 5:00 and 7:00 a.m., these are the suggested bedtimes: School-age children should go to bed between 8:00 and 9:00 p.m. Teens should try to go to bed between 9:00 and 10:00 p.m. Adults should try to go to sleep between 10:00 and 11:00 p.m.
Teenagers get the least amount of sleep, with 97% getting less than the recommended amount each night. In terms of those over 18, adults aged between 45-54 years old are the age group that don't get enough sleep.
Many possible factors cause chronic fatigue, such as underlying medical conditions, nutrient deficiencies, sleep disturbances, caffeine intake, and chronic stress. If you're experiencing unexplained fatigue, it's important to talk with your doctor to find the cause.
Increased tremor amplitude may also result from prolonged sleep deprivation [13]. The simultaneous influence of fatigue and sleep deprivation may strengthen this effect.

You may experience eye twitches or spasms when you have not had enough sleep. Your eyes may even be more sensitive to light, or you may have blurry vision. Sleep deprivation could lead to serious eye problems, such as glaucoma, over time.
Sleep deprivation makes us moody and irritable, and impairs brain functions such as memory and decision-making. It also negatively impacts the rest of the body – it impairs the functioning of the immune system, for example, making us more susceptible to infection.
People who sleep less than the recommended 7 to 8 hours per night are more likely to suffer from chronic conditions like cardiovascular disease, obesity, depression, diabetes and even dementia, Fu and other experts say.
While insomnia can be a symptom of psychiatric disorders, like anxiety and depression, it is now recognized that sleep problems can also contribute to the onset and worsening of different mental health problems, including depression, anxiety, and even suicidal ideation.
Vital Information: In a person who is sleep-deprived, one part of the brain shuts down while other parts will kick in to help compensate. Regardless of the brain's attempt to overcome sleep deprivation, a sleep-deprived person cannot perform mental tasks as well as someone who is well-rested.
Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep. Stressful life events or trauma — such as the death or illness of a loved one, divorce, or a job loss — also may lead to insomnia.
After 24 hours without sleep, you're cognitively impaired. In fact, at just 17 hours without sleep, your judgment, memory, and hand-eye coordination skills are all suffering. At this point, irritability has likely set in.
The good news is that following a single night without any sleep, you'll only need to bank an extra two to three hours than normal to return most functions and your mood to normal. While short-term sleep loss can be made up relatively quickly, this is not the case with longer-term deprivation.
