How long can humans stay on Mars without a spacesuit?

As one of the eight planets in the solar system, the earth has always been the most special existence. It is not only optimistic about the ecological environment, but also breeds countless species, especially the intelligent life of human beings.

We all know that the universe is very vast, so in the past hundred years, with the continuous development of human science and technology, scientists have been committed to finding extraterrestrial life, and are also closely observing and studying other planets in the solar system, hoping that one of them will become a new home for future interstellar immigrants.

Mars and Venus, like the Earth, are in the livable zone of the solar system, so scientists pay special attention to them. Mars, in particular, has been firmly believed by scientists for many years that if Mars is transformed, it will definitely become the first choice planet for future human immigrants. Although the surface of Mars looks barren, the rotation period of Mars is also 24.62 hours, almost the same as a day on Earth. However, because the atmosphere on the surface of Mars is very thin, if humans don't wear spacesuits, they can't survive on Mars at all, and they are likely to suffocate in a few minutes.

This is because humans need oxygen to breathe and sustain life, and without oxygen on Mars, humans can't breathe on Mars at all. So the question is, what will happen if we risk our lives and try to take a breath on Mars? Simply put, your breath will freeze instantly, just like you breathe through a very cold glass window in winter. What is even more frightening is that at the moment you breathe, your body is likely to burst like a balloon.
