Sleep deprivation
Sleep Deprivation
Sleep deprivation (/sli:p dɛprɪˈveɪʃən/) is a condition that occurs if an individual gets less sleep than they need to feel awake and alert. People vary in how little sleep is needed to be considered sleep-deprived. Some people such as older adults seem to be more resistant to the effects of sleep deprivation, while others, especially children and young adults, are more vulnerable.
Etymology
The term "sleep deprivation" comes from the English words "sleep" (from Old English slēp) and "deprivation" (from Latin deprivare, meaning "to take away").
Symptoms
Symptoms of sleep deprivation can include fatigue, mood changes, difficulty focusing and remembering, reduced creativity and problem-solving skills, reduced immunity, weight gain, and increased risk of heart disease and diabetes.
Causes
Sleep deprivation can be caused by a range of factors, including insomnia, sleep apnea, narcolepsy, restless legs syndrome, shift work sleep disorder, and certain mental health disorders such as depression and anxiety.
Treatment
Treatment for sleep deprivation typically involves addressing the underlying cause, such as treating a sleep disorder or changing sleep habits. This can include cognitive behavioral therapy, medication, lifestyle changes, and sleep hygiene practices.
