Ragweed is a type of weed that produces large amounts of pollen, which can trigger allergies in some people. The pollen season for ragweed in Nepal typically starts in late August and lasts until October. During this time, people who are sensitive to ragweed pollen may experience symptoms such as sneezing, runny nose, itchy eyes, and throat irritation. Ragweed is often found in open areas such as fields, roadsides, and vacant lots. It can grow up to 5 feet tall and has small greenish-yellow flowers that produce copious amounts of pollen. While ragweed may not be harmful to everyone, those with allergies should be aware of its presence during pollen season and take necessary precautions to avoid exposure. If you are planning to spend time outdoors during ragweed season in Nepal, it is recommended that you wear a mask to filter out pollen, avoid outdoor activities during peak pollen times (usually midday), and take antihistamines as directed by your doctor. If you experience severe allergy symptoms, seek medical attention immediately.
