Quick Answer
A survival blanket can be a wise choice in cold weather as it can help retain body heat and reduce heat loss, but it should be used in conjunction with other survival techniques such as finding or creating a shelter and starting a fire.
Choosing the Right Blanket
When selecting a survival blanket, look for one that is lightweight, compact, and has a high thermal retention rating. The Space Blanket is a popular choice, weighing in at around 6 ounces and measuring 84 inches by 52 inches. It is also inexpensive and can be easily stowed away in a backpack or pocket.
Using the Blanket Effectively
To maximize the benefits of a survival blanket, use it to cover your body, starting with your head and neck. This can help retain up to 90% of body heat. You can also use the blanket to create a makeshift shelter by draping it over a tree branch or a makeshift frame. However, be sure to avoid creating a “tunnel” effect, which can trap cold air and reduce heat retention.
Signal Fire Considerations
When using a survival blanket in cold weather, it’s essential to consider the risks of creating a signal fire. If you’re lost, a fire can be a lifesaver, but in cold weather, it can also consume valuable fuel and reduce the effectiveness of your survival blanket. If possible, try to start a fire in a protected area, such as a rock overhang or a cave, to reduce wind exposure and conserve heat.
