Effects of sleep deprivation in space

Sleep deprivation is when people don't get enough sleep. In space, it can be very dangerous because without enough sleep, astronauts can't think clearly and make mistakes. That can be dangerous when they are in a complex space environment. Not enough sleep can cause an astronaut to be more forgetful, muddled, and confused. Lack of sleep can also lead to problems with decision making, reaction time, and focus. All of these can put astronauts and the mission in danger.
