The best thermal blankets

Thermal blankets have long been recognised as an essential for outdoor enthusiasts, emergency responders, and anyone braving the cold - indoors or out. Whether it’s winter and you’re heading outdoors with your fire pit, or you’re going out for a summer evening stroll and the temperature is dropping, having some of the best bedding and blankets for your needs can be extremely useful.

Unlike a standard blanket, thermal blankets are lightweight and compact and are often made of heat-reflective, thin plastic sheeting, which helps reduce body heat loss. You’ve most likely seen them used by people working in the emergency services, but if you’re someone who regularly spends time outdoors or on the road, then a thermal blanket is a pretty handy thing to have on hand. Most of them are very portable, too and fold up small enough to fit inside the smallest of rucksacks or even your pocket.

Thermal blankets are mostly used for outdoor use, but there are also blankets made to keep you warm at home too. Although electric blankets have become a staple for those who want warmth without the bulk. These blankets come equipped with heating elements that can be adjusted to your desired temperature, ensuring a cosy sleep environment during colder nights. Also, weighted blankets offer a unique sensation of being hugged or swaddled, keeping you cosy and warm.

FAQs: Best thermal blanket

What is a thermal blanket?

A thermal blanket is a special type of blanket designed to retain heat and prevent body heat loss. It's often made of heat-reflective materials, such as thin plastic sheeting, to provide warmth in cold conditions.

How do thermal blankets work?

Just like thermal socks, thermal blankets work by reflecting back the body's own heat, preventing it from escaping. The heat-reflective material acts as a barrier, trapping warmth and keeping the user warm.

Are thermal blankets the same as emergency blankets?

Yes, thermal blankets are often referred to as emergency blankets, especially when used in survival or emergency situations. They are commonly used by emergency responders and are included in many first-aid kits.

Can I use a thermal blanket as a regular blanket at home?

While thermal blankets are primarily designed for outdoor use or emergencies, they can be used at home, especially in situations where extra warmth is needed. However, they might not provide the same comfort as traditional blankets depending on what type of thermal blanket you have.
