How does climate change contribute to worsening allergy seasons?

• By shortening the duration of pollen seasons

• By increasing CO2 levels and temperatures

• By reducing the number of allergy-inducing plants

• By decreasing pollen production

How do changing wind patterns affect allergy sufferers?

• They decrease pollen production

• They have no effect on pollen

• They increase pollen spread over long distances

• They reduce pollen spread

What role does histamine play in the body's reaction to bug bites?

• It reduces allergic reactions

• It prevents blood clotting

• It strengthens the immune system

• It causes inflammation and itching

Which gene is known to suppress inflammation and is more active in summer?

What environmental factor is linked to the seasonality of skin cancer diagnoses?

• Humidity levels

• Ultraviolet radiation from the sun

• Air pollution

• Soil quality

Which of the following is NOT a factor in the seasonality of cardiovascular diseases?

• Thyroid hormone levels

• Sunlight exposure

• Dietary changes

Why is flu more prevalent during winter months?

• Higher humidity levels

• Increased sunlight exposure

• More outdoor activities

• Cool air and low humidity

What is the main reason for needing a new flu vaccine each year?

• The virus is eradicated annually

• The vaccine is only effective in summer

• The vaccine expires quickly

• The virus mutates rapidly

What is a potential consequence of low vitamin D levels in winter?
