« Russian cosmonaut Konstantin Borisov recorded a video explaining how people sleep aboard the International Space Station (ISS), sharing his tips on how to get the best sleep in zero gravity, as seen in exclusive footage captured from October 2 to 5.
« There’s a sleeping bag tied to one of the walls here – a sleeping bag of this nice pale green colour. It has bed linen, a kind of insert that we change once a month, and the sleeping bag is tied, as you can see, up here to the wall in the middle. It has a lot of attachment points, but I like to leave the bottom part untied to make it easier to bend my legs when I sleep. The bag has a front zip, arm holes, and you can basically just float into it and zip yourself in, » Borisov said.
The cosmonaut also explained that his sleeping bag is constantly ventilated to prevent the accumulation of carbon dioxide.
Borisov went on to demonstrate some sleeping bag upgrades he had devised to help him feel like he was lying in bed rather than being suspended in a vertical position.
« Firstly, there is a rubber band that I use to hold myself so that my body feels supported. And secondly, there is another rubber band, wrapped in a towel for comfort, which I use to hold my forehead. The tension is literally a couple of kilograms, and if you relax completely, like this, you sleep very well, because the hips, the back and the head are touching the wall – it feels like you are lying on the bed. It feels familiar and it’s so much easier for a person to fall asleep. That leaves my arms, which float, touch each other and scare me sometimes, because they are just literally floating. This is not very comfortable, so I tuck them in this way, and this is the position I prefer as the most comfortable for sleeping, » he explained.
Borisov arrived at the ISS aboard the SpaceX Crew Dragon spacecraft with the Crew-7 expedition on August 27. The crew also included NASA astronaut and Crew-7 commander Jasmin Moghbeli, European Space Agency (ESA) astronaut Andreas Mogensen and Japan Aerospace Exploration Agency (JAXA) astronaut Satoshi Furukawa.
Borisov is the third Russian cosmonaut to travel to the ISS aboard a SpaceX rocket, after Anna Kikina and Andrey Fedyaev, who arrived at the station in October 2022 and March 2023 respectively. »
