    Although it is a good idea to have a heat reflective blanket in any first aide kit, there are many other ways to use them.  They can be used to regulate body temperature, build a shelter if you get lost that will keep the hot air out if the shiny side is faced outward, or signal for help. 

    Even companies have designed heat wear using a similar technology.  Columbia's OmniHeat, for example, uses a shiny material on the inside of their coats to help keep in the body heat.  There are other companies who are using linings on the inside of boots and gloves and even pants.  These are great items to keep handy in case of an emergency or a vehicle breaks down in the cold and have to wait for help.

There are many more ways to use heat reflective blankets to your advantage.  If camping on a cold ground, heat blankets make a good bed that keeps the heat around reflected back towards the body to prevent heat loss.   Also placing the blanket behind you when sitting around a fire will increase  the warmth tenfold.

Here are some good uses:

Wrapping it in your sleeping bag for warmth.

Place inside clothing

Placing inside gloves or boots

Make a shelter

Mylar melts at 254 degrees Celsius so you can warm food or boil water if done carefully

Use as a reflective flag to signal for help
