Weightlessness increases astronauts body temperature

The astronauts are weightless in space, and many earthlings are jealous of the possibility of “flight”. But, apart from physical and psychological stress, space travel also affects the body temperature of the crew. A new study shows that the temperature rises during the period of weightlessness. Even at rest, the mark is 1 ° C above the normal value of 37 ° C.

Scientists also found that astronauts observed a kind of stable fever. During training, the temperature often exceeded 40 ° C. The team decided to use sensors on the forehead to measure the temperature indicators of the internal body and brain on the ISS. It turned out that the temperature rise gradually develops over 2.5 months. As a result, the figure reaches 38 ° C. The researchers decided to create a new technology, including a skin temperature sensor and a heat flux sensor capable of detecting even minor changes in arterial blood temperature. This helped determine the cosmonauts' main body temperature before, during and after their stay on the ISS, taking into account the state of rest and training.

Scientists recalled that in zero gravity the body is much more difficult to get rid of excess heat. Moreover, in space, sweat evaporates more slowly than on Earth. Excessive temperature fluctuations can impair physical and cognitive performance and even threaten life. New research can have a positive effect on the future health of astronauts and improve their comfort during long flights.
