Sleep deprivation
hideSleep deprivation, having too little sleep, can be either chronic or acute. Long-term sleep deprivation causes death in lab animals. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight gain.
Complete absence of sleep over long periods is impossible to achieve; brief microsleeps cannot be avoided.
