New NASA research shows more than half the astronauts who return from space come home with reactivated herpes viruses.
Researchers think its because of all the stress astronauts undergo like: zero gravity, cosmic radiation, and separation from loved ones.
The longer they are in space, the more likely the viruses are to reactivate .
Once herpes are in your system, they never go away, they just go dormant and can wake up at any time.
Most of the astronauts didn’t show any symptoms and their reactivated herpes viruses were only detectable using medical tests.
Still, they could infect others, and scientists worry about what other negative impacts on health could result from extended time in space.
