Kalamazoo Public Schools issued the following announcement on Feb 17.
Social Emotional Learning: One of the concepts students explore in SEL is kindness. “The warm feeling of wellbeing that washes over you when you've done something kind isn't just in your head.
It's in your brain chemicals, too. Acts of kindness can release hormones that contribute to your mood and overall well being. The practice is so effective it's being formally incorporated into some types of psychotherapy.” Happy National Kindness Day!
