See How Fatigue Affects Our Astronauts

Astronauts experience conditions that most people may never understand, and this can take a toll on their energy on a few different levels. Extreme conditions can affect astronauts both mentally and physically, and their environment can contribute to their fatigue. Keep reading and see how fatigue affects our astronauts.


To focus on the task at hand, astronauts need to be awake and alert. Unfortunately, this can be difficult while being confronted with so many psychological stressors. In addition to venturing on potentially dangerous missions that take them away from their homes, they have plenty of other concerns to think about. They miss their families while they’re away from home for months at a time, and they miss all the other comforts of home that they’re used to. Being in outer space can also be disorienting, which can sap your energy and take a psychological toll.


Working for months straight will drain anyone’s energy. Now imagine working that whole time without any breaks, and without any gravity. Life itself works differently when you leave the Earth’s atmosphere. Even though you can adjust, it won’t feel nearly as natural as the environment in which you’re used to existing. Astronauts also have a great deal of important work to do, which can be physically tiring, especially when combined with psychological fatigue.

Environmental Factors

There are other environmental factors than gravity that can fatigue our astronauts. Undesirable temperatures and higher levels of carbon dioxide can present a taxing environment, and it can make it extra difficult to sleep. When these factors come together, there are many overlapping elements that can slow down cognitive functioning and lead to chronic fatigue.
