I do Yoga in the morning. Can I consider that an excercise?

After brushing is better because you’ll have protected the enamel of your teeth from the food you’ll be eating! Brushing a 2nd time or simply rinsing after eating is helpful as well.

Yes! It helps stretch your muscles after being immobile when asleep. It also gives you the right amount of energy boost you need to continue the day ahead.
