Heat : Heat rash (miliaria rubra) occurs when your sweat glands become blocked and sweat is trapped under the skin. This can cause a red rash that can either look like little blisters or larger red lumps. It can be itchy or "prickly" which is why many people refer to it as prickly heat. Even though it can be annoying, the good news is that it usually resolves on its own. You can help by preventing sweating such as staying in a cool environment, wear lightweight clothing of breathable material (like cotton), and limiting physical activity in the heat. Calamine lotion can help with the itch. Good luck!
