How to calm down after a long day
Breathe deeply to help you unwind.
Breathing can be very calming and therapeutic. You take so many breaths each day without ever thinking about it, but most of that breathing is shallow and only reaches the chest.
Deep breathing requires you to measure your breathing patterns and take long, slow breaths that extend all the way down into your belly. Breathe in slowly through your nostrils to the count of four.
