Heat Exhaustion Vs. Heat Stroke:  Know the Signs, Know the Difference

Continuing our theme of summer safety, do you know the difference between heat exhaustion and heat stroke? Would you be able to spot the symptoms in someone who is experiencing either of these conditions? Knowing the signs - and the difference between the two - could mean saving someone's life.

Even your own.

Heat Exhaustion

Heat Exhaustion can occur when someone has been exposed to high temperatures and is often accompanied by dehydration. Two types of heat exhaustion exist: water or salt depletion. Water depletion symptoms include excessive thirst, weakness, headache, and loss of consciousness. Salt depletion symptoms include nausea and vomiting, muscle cramps, and dizziness.

Other symptoms of heat exhaustion can include fatigue, sweaty, clammy skin, and a rapid heartbeat.

It is important to treat heat exhaustion, as it can lead to the more serious heat stroke, if ignored. If you or a fellow worker is experiencing any of these symptoms, stop working, get to the shade or an air-conditioned room if possible, drink plenty of water, and rest. It can also help to take a cool bath or shower.

Heat Stroke

From WebMD: "heat stroke is the most serious form of heat injury and is considered a medical emergency. If you suspect that someone has heat stroke -- also known as sunstroke -- call 911 immediately and give first aid until paramedics arrive. Heat stroke can kill or cause damage to the brain and other internal organs."

Signs of heat stroke include red, hot, and dry skin; fever, confusion, convulsions, and/or fainting.

If someone is experiencing heat stroke, call for paramedics and then cool the person's body down by moving them to an air-conditioned room (or shade), and by using fans and ice packs until help arrives.

As always, prevention is the best policy. When the temperatures are on the rise, drink plenty of water and pace yourself. Stay safe!
