Science 4 Everyone: How does allergy medicine work to relieve symptoms? | NBC4 Washington
SUMMARY: Allergies occur when the body reacts to foreign proteins like pollen, food, or insect bites. This triggers the immune system to produce histamine, which binds to H1 receptors on cells to initiate a protective response. Allergy medications, called antihistamines, work by blocking histamine from attaching to these receptors, preventing symptoms such as itching, watery eyes, or even severe reactions like anaphylactic shock. Antihistamines act quickly—within 20 minutes to a few hours—and are effective as long as the allergen remains present, requiring continued use to prevent symptoms. — Ryan Miller, meteorologist and science teacher.
On this Science 4 Everyone, Storm Team4 Meteorologist (and science teacher!) Ryan Miller explains what happens in the body when someone has an allergic reaction and how allergy medicine works to relieve its symptoms.

Restoration efforts on the Elizabeth River are making an impact, experts say
SUMMARY: Once declared dead nearly a century ago, the Elizabeth River is showing signs of revival thanks to ongoing restoration efforts. Long known as one of the most polluted waterways on the East Coast, it’s now a vital part of Norfolk’s waterfront and economy. Efforts led by the Elizabeth River Project, including rain gardens, tree plantings, oysters, and infiltration trenches, have improved water quality. The river now holds an overall C grade, with tributaries like the Lafayette Branch showing marked improvement. In areas like Muddy Point, fish species have increased from 4 to 26. Experts say continued work is still needed.
For decades, the Elizabeth River was seen as one of the most polluted waterways on the East Coast. But it’s seen as the heart of Norfolk’s waterfront. Work to restore, maintain, and improve the river includes partnerships across city, state, and federal lines — all contributing to a healthier, more resilient river system. The latest State of the River Report gives the river an overall C grade, but key areas like the Lafayette branch are now scoring higher.
