Rotating around the earth once in 90 minutes instead of 24 hours can seriously impair the natural sleep-wake rhythm. For living and working on the ISS It is therefore extremely important to closely monitor your own sleep behavior and actively control it, reports TheNextWeb. Findings from sleeping in space can also be translated into advice for people on earth.
On the international space station, space travelers are given an exact daily program to follow a circadian rhythm that ensures sufficient bedtime. If this rhythm got out of control, astronauts would be faced with all kinds of undesirable effects, such as lack of concentration, increased susceptibility to errors or even chronic illnesses.
To sleep well, astronauts have their own small sleeping cabins on the space station. According to NASA, they are important so as not to be disturbed by other crew members. You can also vary the light and use a sleeping bag and belts to create the illusion of lying in a bed. Nevertheless, researchers have found that astronauts tend to sleep less well than under the influence of gravity.
