Hello and welcome to Earth Unplugged. We're here at Mar Lodge in the Kangorms in the Eastern Highlands of Scotland for winter watch. We're filming with the Selex Merlin, a military spec thermal imaging camera that can capture heat as it's lost from my [Music] body. When wrapped up warm, you can see I'm only losing heat from my face and my hands. When I remove my gloves, this shows up as red. This is when it gets serious. My previously insulated chest starts to rapidly lose heat as it's exposed to the freezing [Music] conditions. Animals that call these mountains home have adapted to minimize heat loss by insulating their bodies with feathers or fur to allow them to survive in such bitterly cold winter conditions. [Music] Humans on the other hand need to wrap up in warm clothes to prevent hypothermia which can be deadly in these conditions. [Music] Notice how the snowball is dark blue because it's so cold. As I press my cold hand against my chest, I'm cooling my skin, which is shown as a blue handmark. [Music] The spots on my skin are caused by falling snow hitting my body and cooling it [Music] down. This thermal imaging camera allows you to vividly see how cold conditions can be so perilous. [Music] Check out more from Winter Watch by using the # winterwatch on Twitter.
