You may ask for a healing, just remember that Senior Officers may not like you annoying them all the time with heal requests.
Remember, sleeping helps you heal faster, you can buy bandages and plasters and 'wear' them during combat for a quick fix. Food will heal, but only by a tiny amount, don't rely on it.
You are free to heal whenever and whomever you choose. Just try to be fair about it and don't heal just one player all of the time. Healing a player more than once an hour is probably excessive; if someone needs more than one heal a mission, they're probably trying something that's just too hard for them or they are not properly equipped for.
