I'm trying to look for a word that describes an act, a word that describes the action of putting a body part for example, foot, into a place where there is little or no fresh air, or where little or no fresh air will be able to enter (such as a shoe, a sock, or anything that surrounds, covers, wraps it etc.) in a way that has a negative effect on that body part (esp. an injured body part).
When a part of your body is injured, or has a open wound, it's obvious that you should allow as much air to pass through it as possible to promote healing, and avoid having anything surrounds or covers it that lessens the air flow to the area. So if someone's foot is injured and I want to tell them not to put it in a place where there are little or no fresh air, or where little or no fresh air will be able to enter, is there a verb to describe that? i.e. "don't [...] your foot while it's healing".
