You can check the UV index using the EPA's SunWise UV Index, which helps you determine how safe it is to be outside without sun protection.
Understanding UV Index
The UV index measures the strength of the sun's ultraviolet (UV) radiation. This can help you take necessary precautions to protect yourself from overexposure.
- Low UV Index (0-2): Minimal sun protection is needed.
- Moderate UV Index (3-5): Sun protection, such as sunscreen and sunglasses, is recommended.
- High UV Index (6-7): Sun protection is crucial; seek shade during midday hours.
- Very High UV Index (8-10): Take extra precautions; stay indoors if possible during peak hours.
- Extreme UV Index (11+): Avoid sun exposure; very high risk of harm.
