Water is an essential part of any effort to improve and maintain your health! As such, it is assuredly vital to drink lots of water if you are dealing with allergies. Not only is drinking water essential to maintain your overall health, but it actually has direct benefits for fighting off allergies! When your immune system responds to an allergen, it produces antibodies that release chemicals called histamines that are intended to neutralize the allergen but which also cause an allergic reaction. However, the amount of histamines that are released is directly related to how hydrated you are, which means that drinking water can help reduce the intensity of your allergic reaction, to an extent. That said, drinking water is not considered a stand-alone treatment for allergic reactions but rather an essential part of a treatment plan that could include medication of some sort.
