As the sun moves higher in the sky and temperatures start to rise, so does the UV index.

With a forecasted temperature just below 30 degrees Wednesday and Thursday, the UV index will be very high. 

"The UV index goes from low, which is 0-2; moderate, which is 3-5; high, which is 6-7; very high, which is 8-10; and extreme which would be 11," shared Warning Preparedness Meteorologist for Environment Canada Natalie Hassell. "Exposure to these elements can lead to harmful effects. The UV, or the ultraviolet radiation, that we get from the sun can lead to acute effects, short-term, but usually very painful scenarios. Things like sunburns, in particular, can be quite painful."

She added that chronic sunburns or chronic tanning can also lead to serious consequences such as premature ageing, eye damage, immune suppression and skin cancer. Hassell suggests seeking shade or bringing an umbrella or wide-brimmed hat for protection. 

"We suggest using sunscreen that is labelled broad spectrum and water resistant and an SPF of at least 30."

Hassell also recommends reapplying sunscreen often, even if it's cloudy. 

"Protect your eyes. Wear sunglasses, or if you have eyeglasses, request the ones that have UV lenses."

She added that babies have more sensitive skin and can burn easier than adults.
