The sound you choose to wake up to sets the tone for your day. What’s the best choice? Researchers at the Royal Melbourne Institute of Technology say that neutral (non-melodic) sounds can increase the length of time you experience morning grogginess. That means the wrong alarm sound could make you feel sleepy well into your day. The scientists discovered that each person has a different preference. You can try a favorite song, animal sounds, or whatever you like. Give each a try until you hit on the right combo.
