Hay fever, also known as allergic rhinitis, is an allergic reaction triggered by environmental allergens such as pollen, dust mites, and pet dander. It typically occurs during specific seasons when certain allergens are more prevalent. Here are key indicators of hay fever:
- Seasonal Pattern: Hay fever symptoms often appear during specific seasons, such as spring (tree pollen), summer (grass pollen), or fall (weed pollen).
- Itchy, Watery Eyes: Persistent itchiness and redness in the eyes are common symptoms of hay fever.
- Sneezing and Runny Nose: Frequent sneezing and a runny or stuffy nose are hallmark signs of hay fever.
- No Fever: Despite its name, hay fever does not cause an actual fever.
Distinguishing Cold from Hay Fever:
Colds, on the other hand, are viral infections caused by different viruses and can occur at any time of the year. Here are some key differences between colds and hay fever:
- Duration: Colds typically last for about a week, while hay fever symptoms may persist throughout an entire season.
- Fever and Body Aches: Colds can cause mild fever and body aches, which are not present in hay fever.
- Phlegm and Cough: Colds often produce phlegm and a cough, which are rare symptoms of hay fever.
