Many people include emergency blankets in their first aid and survival kits. Their lightweight and compact nature have made them popular with many outdoor enthusiasts. Be sure to understand what to look for when shopping for emergency blankets.

Do Emergency Blankets Keep You Warm?

Also known as, space blankets, emergency blankets are essential staples for first aid personnel and outdoor enthusiasts. Emergency blankets are designed to keep users warm and to prevent hypothermia.

A threefold action enables emergency blankets to keep you warm:

  • The airtight foil prevents heat loss through convection.
  • It prevents heat loss through perspiration and evaporation.
  • Emergency blankets prevent heat loss through thermal radiation.

The design of emergency blankets prevents heat loss in multiple ways. Their impermeable metallic layer prevents radiated heat loss. 

Emergency blankets keep you warm with the heat you generate in many ways. Once wrapped, emergency blankets provide a barrier between the exposed sections of the skin and the environment, which prevents heat loss and keeps the user warm. 

Things to Consider When Buying Emergency Blankets

Emergency blankets come in many shapes, sizes, and brands. Consider various factors when shopping for emergency blankets because they are not the same.

Length and Weight

The best emergency blanket should be long enough to cover a 6 feet adult. Most emergency blankets come in a standard length of 82 to 84 inches.

Many emergency blankets measure 52 to 54 inches wide and can be used as groundsheets in an emergency or first aid situation. A lightweight emergency blanket is an ideal option to have on the go. 

For outdoor activities, consider getting an emergency blanket that weighs between 2 and 2.5 ounces. However, it is important to understand that lightweight emergency blankets sacrifice comfort. 

Material 

When buying an emergency blanket, consider what material the blanket is made of. Consider choosing emergency blankets made of lightweight and insulating materials. 

Although wool blankets are more comfortable, they can be relatively heavier than other materials. Mylar is a popular emergency blanket material because of its heat retention and lightweight nature. 

Mylar is quite affordable compared to blankets made from other materials. Also, it is compact when folded, which means you can take as many as you want on a camping trip or rescue mission. 

Waterproofing 

Emergency blankets should keep you relatively warm even in the stormiest of weather. Be sure to choose one that is also waterproof.

One of the ways we lose heat from our bodies is through conduction. A soaked up blanket will cause you to lose heat faster, which makes it unsuitable for use in storms, floods, or tornados. 

An excellent emergency blanket should be made from a material that is 100 percent waterproof. Such a blanket will not only keep you warm, but it will also keep you dry.

Windproof

When the wind blows on your skin, it carries away surface heat through convection. This is why it can get chilly when it is windy.

Go for emergency blankets with windproof properties. They provide the best insulation against the wind.

Snow and rain are not the only elements that can make you cold. Strong winds can also send you into a hypothermic shock if your body has poor heat retention.

Durability 

Unfortunately, the most lightweight emergency blankets are not the most durable. Light emergency blankets measuring 12 microns thick or less are likely to last a shorter period. 

When thinking long-term, consider getting emergency blankets that are at least 80 percent wool. Although they are heavy and bulky, they are also more durable.
