What is the impact of the vacuum of space pressure on astronauts during a spacewalk?

The vacuum of space pressure can cause a variety of health issues for astronauts during a spacewalk. Without the pressure of Earth's atmosphere, bodily fluids can boil, leading to swelling and potential damage to tissues. Additionally, the lack of pressure can cause the lungs to expand, making it difficult to breathe. Overall, the vacuum of space pressure can be harmful to astronauts if they are not properly protected.
