Do Female Astronauts Wear Bras In Space?

It’s a question that many of us may have thought, but few ever stop to ask. Besides, they are so important for females here on earth. But do female astronauts need to wear bras in space? And do they even do so? Let’s find out.

So, do female astronauts wear bras in space? Female astronauts do generally wear bras in space. Although, bras are not commonly worn for their primary purpose – offering support. Instead, female astronauts will typically wear bras for comfort, and to protect their modesty from male astronauts and the various cameras throughout the space station.

It actually makes sense when you think about it.

But let us continue to see why this particular undergarment is so useful for the female astronaut.

And don’t just take my word for it.

I’ll be citing a NASA astronaut with more than 30 years of experience!

Why Do Female Astronauts Wear Bras In Space?

Female astronauts are likely to wear bras for several different reasons. They are multifunctional, after all. Preventing inertia and providing coverage appears to be the main reasons.

And at this point, it’s important to note that female astronauts primarily wear sports bras.

These provide more comfort, compression and are generally much more applicable.

And there are many benefits of wearing this particular style of bra in space.

While there is no noticeable pull from gravity, there is still inertia.

In physics, this term applies to the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed or direction of motion.

So, in the context of bras and breasts; bras essentially prevent too much of a change in velocity.

Or in other words.

Bras prevent a female astronaut’s breasts from being subjected to the conditions of microgravity.

And then there is the benefit of coverage.

Or in other words, preventing detailed outlines.

It is a professional setting and a workplace, after all.

Even if it is not your typical office environment!

Here is what Clayton C. Anderson, A NASA astronaut for over 30 years and who has been on 6 spacewalks has to say on the matter:

“In micro-gravity on board the International Space Station (ISS) I can only speak from observation and not personal experience. Women typically wear athletically designed “sports bras” during their workout sessions (2.5 hrs/day, using combinations of a treadmill, stationary bicycle and weight machine called ARED (Advanced Resistive Exercise Device)) on ISS, and often wear similar undergarments during the work day. To my knowledge, and having flown with four different females during my two missions in space, I recall no comments or observations of them having any type of special challenges or experiences in zero gravity.”

It makes even more sense that they are worn specifically during any exercise.

And astronauts do have to remain very physically fit to undertake their duties. Not only that but exercise has another important purpose in Space.

As NASA outlines: “Exercise is an important part of the daily routine for astronauts aboard the station to prevent bone and muscle loss”.

And one side effect of increased exercise and activity – fat loss.

And we all know what breasts are primarily comprised of don’t we.


Female astronauts wear bras in space. Sports bras, that is.

And they do so for various reasons; even if the conditions are immensely different compared to here on Earth.

At least now you know.
