PRINCETON, NJ (WKOW)-- Have you ever wondered why elephants have hair on their heads?
A team of Princeton University scientists have the answer. It's to keep them cool. The hairy covering of other animals helps keep them warm during cold weather. But, the Princeton study found the elephant's hair helps keep heat away from the animal's skin.
The team found that in a breeze, the hair can help them lose up to 23 percent of their body heat.
