Alternate Nostril Breathing

This breathing exercise variation has been practiced for thousands of years as a form of meditative breathing. As you inhale, place your finger over your right nostril and only breathe through your left. On the exhale, switch nostrils and only breathe through your right. You can breathe at whatever pace is comfortable for you, either a 5-8 ratio, a 4-7-8 ratio or whatever pace feels most relaxing for you (see "counted breathing," above). Repeat this exercise for up to five minutes.

If you’re too lazy to read the previous one:

Inhale to the count of four, hold for a count of seven, then exhale to the count of eight. Repeat three times
