What temperature water is recommended for ear irrigation?

• A. Cold water
• B. Lukewarm water
• C. Hot water
• D. Room temperature water

Answer: (B)

The important idea is to use irrigation water that feels like body temperature to keep the ear comfortable and avoid triggering dizziness or tissue irritation. Lukewarm water, about 37°C (98.6°F), is best because it matches the temperature of the ear and the surrounding tissues. When the water is close to body temperature, the sensory input to the ear isn’t dramatically changed, which helps prevent vertigo, nausea, or a burning or chilling sensation in the canal. To check, test the water on your wrist or the back of your hand; it should feel warm and comfortable, not hot or cold. Cold water can provoke dizziness and discomfort, hot water can burn, and room temperature water is cooler than body temperature and may be less comfortable. So, lukewarm water is the safest and most comfortable choice for ear irrigation.
