When your head is aching from sinus congestion and your nose is plugged up, going to yoga class is probably not the best option. Rather than completely neglecting your yoga practice, opt for a minisequence at home to open up your chest and improve your circulation.
If you are looking for a little more of a workout, simply complete a few rounds of Sun Salutations between each congestion-soothing posture.
