Can You Be Allergic To Sunlight?

The video discusses the dangers of UV radiation, including DNA damage and sun allergies like solar urticaria and polymorphous light eruption (PMLE). Solar urticaria causes hives due to an immune response, while PMLE results in delayed rashes. Both conditions are rare, with PMLE being more common. The video also explores theories about these allergies and offers additional resources for learning about immune system reactions.

What is a potential consequence of UV radiation from the sun?

• Increased energy levels

• Enhanced skin hydration

• DNA damage

• Improved eyesight

What is solar urticaria?

• A type of sunburn that heals quickly

• A condition where sunlight improves skin texture

• A rare allergy causing hives from sun exposure

• A common cold triggered by sunlight

How does the immune system typically respond to allergens?

• By producing more red blood cells

• By releasing histamine

• By increasing body temperature

• By reducing blood pressure

What is a characteristic of polymorphous light eruption (PMLE)?

• It causes permanent scarring

• It appears immediately after sun exposure

• It can improve with repeated sun exposure

• It is triggered by cold temperatures

How is PMLE different from solar urticaria?

• PMLE causes immediate hives

• PMLE is less common than solar urticaria

• PMLE is caused by food allergens

• PMLE has a delayed reaction time
