Hot summer temperatures can be especially harmful for those who work or play outdoors in direct sunlight or in hot environments, making them susceptible to heat-induced illnesses such as heat stress, heat exhaustion or the more serious heat stroke.

In high temperatures, many people keep working (or playing) in conditions until sweating is not enough to sufficiently cool their bodies. At this point, they may experience heat cramps or life-threatening heat exhaustion, which if not dealt with immediately can easily lead to a potentially fatal medical emergency: heat stroke.
