Why does it feel hot when breathing through the nose

The sensation of feeling hot when breathing through the nose can have several possible causes. Firstly, it could be due to the increased temperature of the air you are breathing in. If the air is warmer than usual, it will feel hot when it passes through your nasal passages. Secondly, it could be a sign of a sinus infection or other nasal-related issues. A sinus infection can cause the nasal passages to become inflamed and swollen, leading to a sensation of heat when breathing. Additionally, environmental factors such as high humidity, poor ventilation, or exposure to certain pollutants can also contribute to a feeling of heat when breathing through the nose. If you are experiencing this sensation and it persists for an extended period of time, it is recommended that you consult a healthcare professional to get a proper diagnosis and treatment advice.
