It’s springtime, which means your allergies may already be causing a runny nose, watery eyes, sneezin

Allergies occur when your immune system reacts to a foreign substance such as pollen, bee venom or pet dander. Your immune system produces substances known as antibodies. Some of these antibodies protect you from unwanted invaders that could make you sick or cause an infection. When you have allergies, your immune system makes antibodies that identify your particular allergen as something harmful, even though it isn't. When you come into contact with the allergen, your immune system's reaction inflames your skin, sinuses, airways or digestive system.

Whats the best way to stop a mosquito bite from itching?

Its a simple anti-histamine pill. A mosquito bite triggers your immune system to respond. The mosquito's saliva has anti-coagulants that make your blood easier to drink.

Your body sends anti-bodies to fight these foreign enzymes. The anti-bodies set off the production of histamines which causes the blood vessels and surrounding skin to swell, making the bite red and itchy too.

Anti-Histamines block histamines from causing inflammation. Oral doses of anti-histamines have been shown to work best.
