"Sun disease" isn't a single, formally recognized medical term. Instead, it's an umbrella term encompassing several conditions triggered or worsened by sun exposure. These range from common problems like sunburn to rare genetic disorders.
Conditions Related to Sun Exposure:
Several conditions arise from sun exposure, including:
- Sunburn: The most common effect of excessive sun exposure. It's characterized by red, tender skin, sometimes with blisters. [Source: Canada.ca First Aid Advice for Sunburn]

Importance of Sun Protection:
Protecting yourself from the sun is crucial to preventing these conditions. This includes:
- Using sunscreen with an SPF of 30 or higher.
- Seeking shade during peak sun hours.
- Wearing protective clothing.
Sunlight, while essential for Vitamin D production, also carries harmful UV radiation. Excessive exposure increases the risk of skin cancer and other health problems. [Source: CDC Sun Safety Facts]
