What is the recommended ear lavage water temperature?

• A. Lukewarm (about 37 degrees Celsius)
• B. Cold
• C. Hot
• D. Room temperature (about 25 degrees Celsius)

Answer: (A)

The main idea is to use water that is near body temperature to avoid provoking the ear’s balance system or causing irritation. Water around 37°C (about 98.6°F) is warm enough to be comfortable and gentle on the ear canal, while not triggering the inner ear’s vestibular nerves. If the water is too cold, it can cause dizziness, nausea, or a discomfort reflex; if it’s too hot, it can burn or irritate the ear and also provoke dizziness. Room temperature water is cooler than body temperature and can be uncomfortable or less well tolerated. So, lukewarm, close to body temperature, is the recommended choice to ensure safety and comfort during ear lavage.
