A pressure suit is like wearing a special suit that protects your body from really high or really low pressure.
Think of it like a balloon. When you blow it up, it gets really hard and tight because there is a lot of air pushing on the inside.
The same thing happens to our bodies when we go high up in the sky or deep under the ocean. There is less air pressure up high and a lot more pressure under the water.
When people have to go up really high or deep underwater, they wear a pressure suit to help protect them from these extreme pressure changes.
Pressure suits are a special kind of clothing made out of really strong materials that can keep the pressure from crushing the body. The suit also has air pouches that help to balance pressure levels with the outside environment.
So, with a pressure suit on, we can keep our bodies from feeling the intense pressure changes and stay safe.
