Let’s be honest. Most of us have sung in the shower at some point, and the singing is not always of the greatest quality. You might wonder why I include this suggestion in a list of productivity tips. Well, it turns out that singing in the shower gives us a whole lot of physical and mental health benefits. You may not remember it, but your mother probably sang lullabies to you as a baby. So when you sing it takes you back to what was a fundamental learning period of your life. Physically, singing leads to a higher immune competence, meaning you are less likely to catch bugs. People who sing also have lower cortisol levels, meaning less stress, and better hearts.
