In addition to adapting to zero gravity, astronauts also face serious risks from fire and bland-tasting foods.
Let's learn more about how astronauts' lifestyles differ when they're in space.

Picture of an astronaut in space.
Fire is one of the biggest hazards astronauts face during spaceflight. In microgravity, fire behaves very differently than it does on Earth.
Fires in space can burn hotter and spread more slowly, making them harder to detect initially.
This is dangerous because the fire can burn materials that are normally non-flammable on Earth, releasing toxic chemicals into the spacecraft's air.
A study by ZARM scientists at the University of Bremen in Germany has shown that the low-pressure environment and high oxygen content of future spacecraft will increase the risk of fire. Scientific awareness.
For example, the oxygen level in a spacecraft flying to Mars could reach 35%, which could cause a fire to spread three times faster.
Since there is no safe place to escape on a spacecraft, it is important to understand how a fire behaves under these conditions.
The goal of the research is to develop better fire safety protocols to keep astronauts safe during long space flights.
Food in space is tasteless.
Food in space often tastes good to astronauts, and new research from the Royal Melbourne Institute of Technology (RMIT) in Australia sheds light on why. The research shows that the perception of smell, which greatly influences the taste of food, can be altered in a confined environment like the International Space Station (ISS). The increased loneliness and isolation that astronauts often experience can affect their sense of smell and taste.
In addition, being in zero gravity causes bodily fluids to move from the lower to the upper body, causing swelling of the face and nose. This condition interferes with astronauts' sense of smell and taste, making food taste less appetizing and less appetizing. space.
In this study, researchers used virtual reality goggles to simulate the ISS environment and tested changes in the perception of vanilla, almond, and lemon essential oil odors. The results showed that vanilla and almond odors were more intense in the simulated ISS environment, while lemon odor remained unchanged, suggesting a relationship between environment and odor perception.
It is hoped that this research will help create more suitable foods for astronauts so that they can better meet their nutritional needs during long flights. The results of this study could also be used to increase the nutritional intake of people in other isolated settings, such as nursing homes.
Life in space is challenging and very different from life on Earth. From fire hazards to bland-tasting foods, astronauts have to adapt to a lot of new things. Research and development continues so that astronauts can carry out their missions safely and healthily, with the hope that these discoveries will also benefit life on Earth, especially for those living in isolated conditions.
