Fact or Fable? Most body heat is lost through the head

Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.

Why do we get Hiccups?

why do we get hiccups

Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?

What are Hiccups?

Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat.

The British Skeleton Team – Sliding to Victory

skeleton olympic

How would you like to slide down a very steep and winding track of ice on something very similar to a tea tray at around 140km per hour? Yes, no, maybe. Well, there are people out there who can and do want to. And what’s more, they’re really rather good at it.
 Alongside Bobsleigh and Luge, the Skeleton is one of three sliding sports that take place on artificially refrigerated ice tracks. It’s a really white knuckle experience as each skeleton athlete pushes their sled one handed away from the start before lying down with their face first as they travel the track, using their shoulders, knees and toes for steering.
