Jala Neti is a yoga technique that involves cleaning the nasal passages with a warm saline solution. The use of warm water is generally recommended for Jala Neti because it helps to soothe and moisturize the nasal passages, making it easier to clear out any congestion or mucus.
Warm water also helps to dilate blood vessels in the nasal passages, which can increase blood flow and improve breathing. This can be especially beneficial for people with nasal congestion or allergies. Additionally, using warm water can help to soften and remove any crusty or hard mucus that may be stuck in the nasal passages.
It's important to note that the water used for Jala Neti should not be too hot, as this can cause irritation or burning in the nasal passages. The water should be at a comfortable lukewarm temperature, around body temperature.
It's also important to note that if you have any chronic nasal problems, you should consult with a doctor before practicing Jala Neti or any other nasal irrigation techniques.
