Allergies are caused by an immune reaction to allergens like pollen or dust and usually cause sneezing, itchy eyes, and a runny nose without fever. A cold is a viral infection that causes sore throat, fever, body aches, and lasts a short time. Allergies last longer and are not contagious, while colds are contagious and temporary.
Many people feel confused when they experience sneezing, a runny nose, or congestion and wonder if they have allergies or a cold. Both conditions share similar symptoms, which makes it hard to tell the difference, especially in early stages. This confusion often leads to wrong treatment and unnecessary worry.
People search for “allergies or cold” because the symptoms feel almost the same. However, the causes, duration, and treatment of allergies and colds are very different. Knowing the difference helps you take better care of your health and avoid spreading illness to others.
This article explains the difference between allergies and a cold in simple language. You will learn symptoms, causes, real life examples, common mistakes, practical exercises, and helpful tips to identify what your body is experiencing.
