## Introduction

Mylar blankets, also known as space blankets, are often seen in emergency kits and outdoor survival gear. They’re lightweight, compact, and exceptionally versatile, making them an indispensable tool for anyone venturing into the great outdoors or preparing for potential emergencies. But how exactly do they work, and how can you utilise them effectively in an emergency situation? This blog post will detail everything you need to know about using Mylar blankets in emergencies.

## Understanding Mylar Blankets

### What is a Mylar Blanket?

A Mylar blanket is made from a thin sheet of plastic, usually PET film, coated with a metallic reflecting agent. This design allows it to return up to 90% of an individual’s body heat back to them. Although they’re thin and lightweight, they’re incredibly durable and waterproof, making them an excellent resource for a variety of survival situations.

## How to Use Mylar Blankets in Emergencies

### Maintaining Body Temperature

The most common use for Mylar blankets is to maintain body temperature during cold conditions. When wrapped around the body, the blanket reflects back body heat, helping to prevent hypothermia. In emergencies, it’s crucial to keep warm to avoid shock and other potential health issues.

### Signalling for Help

In addition to keeping you warm, Mylar blankets can also be used as a signalling device. The reflective surface can catch the sun and be used to signal aircraft or rescuers in the distance. This could be a lifesaver if you’re stranded in a remote area.

### Shelter Building

The durability and waterproof qualities of Mylar blankets make them ideal for emergency shelter building. They can be used as a roof to protect from rain or as a groundsheet to insulate from the cold, damp ground.

### Collecting and Purifying Water

A Mylar blanket can be shaped into a makeshift bowl to collect rainwater or morning dew. You can also use it in conjunction with sunlight to purify collected water through solar disinfection, a process that involves exposing water-filled containers to the sun.

## Other Uses

While less common, Mylar blankets can also be used for first aid purposes such as splinting broken bones or creating a sling. They’re also a great addition to a pet’s emergency kit, providing them with warmth and comfort in stressful situations.

## Conclusion

Mylar blankets are a vital tool for anyone looking to prepare for emergencies or outdoor adventures. Their ability to retain heat, signal for help, provide shelter, and even aid in water collection and purification make them a valuable asset in any survival situation. So, whether you’re planning a wild camping trip in the Scottish Highlands or compiling an emergency kit for your home, don’t forget to pack a Mylar blanket! Your safety and comfort may depend on it.
