Naval Submarine Medical Research Laboratory

A naval submarine medical research laboratory is a place where scientists can do experiments and studies to learn how to keep people healthy while they are on a submarine. Submarines are ships that go underwater, and so being on one for a long time can be very hard for people's health. Scientists do experiments and research in the lab to find out how to make sure that people are healthy and safe while they are on the submarine. They might look at what types of food people should eat on the submarine, how to make sure the air is clean, and how to make sure people are exercising and getting enough rest.
