How to protect yourself from different UV rays?

The UV Index was developed by the U.S. National Weather Service and the U.S. Environmental Protection Agency to provide information that would be useful in planning activities and preventing the risk of overexposure to the sun.

The UV index is determined daily and predicts the intensity of UV radiation, which reaches the earth's surface, on a scale from 1 to 11+. 1 means low risk, and 11+ means extreme risk. In determining it, several factors are taken into account such as: degree of cloudiness, height of the sun, latitude, altitude, presence of ozone in the atmosphere, reflection from certain surfaces and other local conditions that affect the UV radiation that reaches the surface on Earth.

The UV index varies throughout the day. Thus, in the summer months, in the morning and in the evening, the risk of UV radiation is low, until 11 am and after 5 pm it is moderate, and it is highest in the afternoon.

UV Index  Risk   Recommendations
Lower than 2     Low risk  There is a possibility that the snow will increase the reflection and lead to damage to the skin and eyes. Use sunscreens. On sunny days, wear sunglasses
3-5 Medium risk This is a common example when the weather is cloudy, but be careful because 80% of UV rays can pass through the clouds.     Use sunglasses with UV protection. Use creams with the appropriate factor.
 
6-7 High risk Children are especially susceptible to sunburn when carelessly exposed to the sun when the UV index is at high risk.     Practice wearing light white cotton clothes. Use creams with an appropriate sunscreen. Stay in the shade. Limit your stay outdoors from 11 am to 4 pm.
8-10 Very high risk Damage to the skin can occur very easily.     Be careful when you are on the beach because the sand and water further increase the UV index. Use sunscreen agents with an appropriate SPF. Avoid staying outdoors between 11am and 4pm.
11 + Extreme risk    Damage to the skin can occur very easily, and fair skin burns in just a few minutes if not properly protected.     Take complete protection measures (apply a cream with a high protection factor, cover the child's body with white cotton clothes, be sure to protect the head with a hat and wear sunglasses with UV protection) - do not stay outdoors in the period from 10-16 o'clock.
