1. It Gets Really Cold
The very first thing you’ll probably notice is how cold space actually is. However, it’s the actual vacuum of space that causes the heat to be transferred away from your body. This will have an effect on the mouth, lungs and eyes as all the water vapor will evaporate extremely quickly. You will not feel cold as we know outside cold to be like in winter but because the body will not have any water or air to insulate it, you will freeze to death.
2. Skin Cancer Develops In Seconds
When you go outside the earth’s atmosphere protects us from the ultraviolet rays of the sun as it minimizes the impact of the radiation and the most we end up with is a sunburn. So that protective shield is no more in outer space and your skin with start to burn very quickly which will result in skin cancer because of the exposure to the radiation.
3. Glimpsing At The Sun Can Cause Blindness
The same rules appeals in outer space as they do on earth as it relates to looking a the sun, don’t stare directly at the sun. On earth it is estimated that it would take approximately one minute and thirty seconds of staring directly at the sun for it to cause serious damage to your eyes, however in space it is said that just staring at the sun for a glimpse can result in serious eye damage.
4. You Will Inflate
What the space scientists call ebullism is going to set in. This is a very simple process, nitrogen is in the blood stream of every human, as the nitrogen dissolves due to the space vacuum, it will begin to form a myriad bubbles. They will be so many that as they expand so will your body, beginning with the extremities, until your entire body has expanded.
5. Complete Shutdown Of Your Brain
While all the air and the water is being sucked out of your body, the same will occur in your skull, without these vital resources, your brain will shut down in approximately 15 seconds. Once this occurs, all consciousness will be lost and chances of survival after that is little to none.
6. Ruptured Lungs
Due to space’s vacuum, you will lose all the air in your lungs, which will cause a massive buildup of atmospheric pressure in your lungs, similar to scuba drivers getting the bends. At this point your lungs are about to completely rupture under pressure.
