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.
How to Clean Water
With poor living conditions and water shortages increasing every year across the world, the question of how to clean water efficiently is becoming ever more important.
Does Everyone Have Clean Water?
When you have clean, safe water available at the turn of a tap it’s very easy to take it for granted. But almost 750 million people don’t have access to clean water; that’s one person from every ten in the world’s population. There are many reasons for this, from poverty to poor management by governments.
