Heatstroke First Aid

The signs of, and treament for, heatstroke

Heatstroke is the most serious and deadly form of heat-related illnesses. Your body temperature gauge bascially breaks, and you keep getting hotter without the natural ability to cool down again.

This can happen quickly, and the best defense is just to stay hydrated and not overwork yourself in the heat.

Heatstroke can come on suddenly by itself, or arise as a complication or worsening of heat exhaustion.

Heatstroke is very serious, and untreated can result in brain injury, organ injury, or death.

How to avoid heatstroke

• Layer your clothing. This allows you to remove or add layers as needed to regualte your temperature.
• As you get warm, take off layers.
• Stay hydrated. Drink plenty of water, frequently sipping it throughout the day.
• Do not overexert yourself in the heat. This may sound silly or impossible—we often go hiking on hot summer days. The keys is to pace yourself and not over-exert. It is important to keep that in mind and not push too hard when it is really hot out.
• Keep an eye on each other. Pay attention to the well being of the person on either side of you and everyone has at least three people watching out for them (themselves and two others). Also, since confusion and reduced cognitive abilities are symptoms of many outdoors-related ailments and illnesses, you are never the best judge of how sick you might be.
