Body rhythms

If you take off your watch for a whole day and only eat when you’re hungry or sleep when you’re tired, you’ll find that you are more or less following the same pattern as you’ve anyways done. You might not know what time it is, but your body certainly does. These daily life patterns are called circadian rhythms. In short, they are our body clocks. New discoveries are helping scientists to know more about the working system of these clocks. This can help scientists answer questions like, why do people wake up in the middle of the night after travelling across time zones. In fact, scientists believe that kids shouldn’t stay up late as that would make them do worse in tests and for adults, working night shifts can lead to higher rate of heart diseases and obesity.
