Even when it is not hot outside, heat related illnesses can still be contracted! A car can reach up to 110 degrees on a 60 degree weather day. 
Heat exhaustion can take place when the outside temperature is only 57 degrees. It is important to be aware of the temperature outside and what type of environment you will be working in.
Wearing a jacket or sweater outside when it is not hot is a smart idea, but always remember that the temperature indoors will most likely be warmer. Always bring an extra lighter weight shirt or something to change into for working conditions. To learn more, please visit Health Research Funding or read more here.
