As the winter sky becomes darker, we can always illuminate ourselves from within with simple sun breaths. To try: From Mountain pose, relax your belly, then take 5–10 complete breaths using your full lung capacity. Try to let each inhale and each exhale last around six counts. Inhale and slowly raise your arms out to the sides and up overhead, bringing your palms together. Then exhale and slowly draw your palms down the midline of your body until your thumbs rest at the center of your chest. Integrate your movement and breath so that one full inhalation brings your arms all the way up and one complete exhalation takes your arms all the way down. With each breath, focus on filling and emptying your lungs completely. Repeat this for several minutes. Then relax your body, soften your breath, and place one hand on your belly and the other hand on your chest. Feel for your heartbeat and connect with the warmth of your own internal flame.
