Hot Bath

Hydrotherapy has been used in history to treat a number of conditions, including influenza, typhoid fever, and pneumonia.[1] Water can store heat more than any other substance and can give off heat without greatly changing temperature. Water is non-irritating, non-allergenic, has solvent and nutritive properties, and is inexpensive. Hydrotherapy’s mode of action affects the respiratory system, nervous system, circulatory system, digestive system, mood, and immune system.[2] [3] If you have persistent symptoms, such as a fever, a hot bath to temporarily elevate the body’s temperature can help relieve symptoms.[4] This remedy requires help from another individual.


Step 1

Check temperature and heart rate prior to hot bath to establish patient’s baseline.

Step 2

Have the patient drink three cups of herbal tea (dandelion, mullein, peppermint, licorice, lobelia, or warm water) prior to the hot bath.

Step 3

Fill a tub with hot water. Check water temperature and maintain a target range of 102-105F throughout treatment.

Step 4

Have patient immerse themselves in the tub, covering their entire body except above the neck.

Step 5

Apply cold towels to the patient’s forehead and wipe face with a cold towel. Replace the towels to the forehead often.

Step 6

Keep patient’s index finger above water to check heart rate and saturation.

Target: heart rate <120, oxygen saturation >92%, temperature <102F
Stop treatment if heart rate is >120

Step 7

Have patient stay in the water for 20 minutes, or shorter as patient tolerates. Encourage them to continue drinking herbal teas (or warm water) while immersed.

Step 8

Once finished, cool the patient’s chest, and then legs with cold towels. Pour cold water on their chest and limbs 3x.

Step 9

As soon as the patient leaves the bathtub, have them dry thoroughly and dress warmly.

Have the patient rest for 30 minutes after treatment.

Step 10

Have the patient drink two cups of herbal tea (dandelion, mullein, peppermint, licorice, lobelia, or warm water)


Perform 2x a day until temperature is normal, and chest congestion resolves.
