Hot VS. Cold Basics
The prefix "hyper-" in hyperthermia means this.
What is over / too high / above normal?
The clear liquid your body produces on your skin to help you cool off when you get hot.
What is sweat?
The main thing your body does automatically—shaking your muscles rapidly—to warm you up when cold.
What is shivering?
True or False: Your heart rate speeds up when you get dangerously hot.
What is True?
The simple liquid you should drink to help prevent heat exhaustion on hot days.
What is water?
The prefix "hypo-" in hypothermia means this.
What is under / too low / below normal?
When your body turns flushed or red in the heat, it is because blood vessels near your skin do this to release heat.
What is open up / widen (or vasodilation)?
When you are cold, blood vessels near your skin tighten up so warm blood stays near these vital body parts.
What are organs (or heart/brain/lungs)?
True or False: Shivering speeds up when severe hypothermia gets extremely dangerous and late-stage.
What is False (shivering stops in late severe hypothermia)?
The first thing you should do for someone showing signs of overheating outdoors.
Move them into the shade / air conditioning / cool area?
This 11-letter word describes the body's natural state of keeping internal conditions balanced and stable.
What is homeostasis?
Painful muscle tightness in your legs or stomach caused by heavy sweating and dehydration in heat.

What is confusion / altered mental state?
Why you should rewarm a freezing person slowly instead of throwing them into hot water right away.
Fast warming can cause shock / heart problems?
The main brain region that acts like your body's built-in thermostat.
What is the hypothalamus?
The most dangerous, life-threatening heat emergency where your body stops sweating and overheats completely.
What is heat stroke?
Why you should get out of wet clothes immediately when exposed to cold weather.
Because wet clothes pull heat away from your body much faster.
