(CNN) - Have you ever developed a cold sore after a stressful time at work or home?
Thatโs herpes virus re-activating and the same thing happens to astronauts.
New NASA research shows more than half the astronauts who return from space come home with re-activated herpes viruses.
They think itโs because of all the stress they undergo like zero gravity, cosmic radiation and being separation from loved ones.
The longer they are in space, the more likely the viruses are to re-activate.
There are many different herpes viruses and they cause things like chicken pox, shingles, genital herpes and cold sores.
