Before sending into space, astronauts are subjected to a QUARANTINE PROGRAM in order not to carry any infectious disease from our planet, which is crucial for the space exploration program to succeed. I strongly recommend NASA, ISRO, SPACEX, BLUE ORIGIN and other space explorers who are sending or planning to send manned space crafts for space exploration to adopt UCTR in their quarantine protocol. Astronauts can continue to practice this simple UCTR in the space also to protect themselves from even from allergic rhinitis and nasal congestion.
Several days before the mission ended, they began to worry about wearing their suit helmets during re-entry, which would prevent them from blowing their noses. The build-up of pressure might burst their eardrums. Deke Slayton in mission control tried to persuade them to wear the helmets anyway, but Schirra was adamant. They each took a decongestant pill about an hour before re-entry and made it through the acceleration zone without any problems with their ears."
Astronauts would not have suffered even a bit like this, if somebody had already invented UCTR @that time.
