A New study was reporting that “microgravity consistently increases core body temperature, with fluid shifts playing a crucial role in thermal balance.”
Human bodies respond differently to temperature changes based on age, fitness level, and body fat, among other parameters.
In environments with near-zero gravity like the space, the human body changes significantly, affecting the bones, muscles, the heart, the immune system, the metabolism and even individual cells.
Specifically, the researchers reported that while the feet and hands become cooler as the body spends more time in microgravity, the head, abdomen, and the core get warmer.
The Core body temperature may increase from 36.3°C to 37.8°C (with 30% lower sweating and 36% higher metabolism) in 2.5 months under the influence of the microgravity.
