During these times it is a good idea to perform the One Hundred Breathing daily. Try 3 sets of breaths with 5 count inhale, 5 count exhale. 3 sets with 5 count inhale, 10 count exhale. 3 sets of 10 count inhale, 10 count exhale. It brings new air in, old air out. Like house cleaning for your lungs! It keeps your lungs pliable. You can also use it as an indicator to check how you feel during it over the months. How does it feel today? how does feel next week? If it gets significantly harder, then maybe you can make a call to your health professional. You can perform the One Hundred breathing, sitting or standing or anywhere.
