Steam from hot showers helps relieve blocked nasal passageways as a humidifier does. It introduces moisture, allowing for a more thorough flow of mucus which helps in clearing nasal passageways. It involves covering the individual’s head with a wet towel, filling a container with hot water, and then placing the head of the individual over the container. This is meant to trap the steam from the hot water, which is then inhaled. It can be done multiple times per day, although caution should be taken as dealing with hot water can be dangerous.
A hot shower can also be taken whenever necessary and is normally harmless in moderation. Once a day of showering is recommended mainly because excessive showering may cause dry skin and problems if oils don’t develop. Typically, a hot shower should only last between 5 to 10 minutes, as it might cause dizziness and burns.
