If you get sick all the time, you may be able to blame your immune system. Yoga can help stimulate the four main physiological systems that are linked to the immune system: the circulatory, digestive, nervous, and endocrine systems, says Surya Kolpakov, a certified yoga therapist and author at Yoga Lifestyle Coach.

Poses that affect at least one of these four systems help bolster immune function, says Kolpakov, who teaches workshops on yoga for immunity. “For example, I’ve found that bow pose is one of the best ways to stimulate digestion and improve immunity,” he says.

To help stave off colds and other bothersome bugs, he recommends these immunity-boosting yoga poses.

Down Dog Vinyasa

This short dynamic sequence, targeting the circulatory system, is an excellent all-around warm-up. It stretches and strengthens most of the major muscle groups, promoting circulation and helping white blood cells move through the body to fight invaders.

Begin in plank pose splaying your fingers out wide on the mat to create a firm base.

Downward-Facing Dog Pose

Lift your hips up into downward-facing dog pose (adho mukha svanasana). Take a couple of long breaths here.

Back To Plank Pose

Slowly lower the hips and bring the body parallel to the floor, returning to plank pose.

Upward-Facing Dog Pose

If comfortable, lower the hips even further bringing the chest through the upper arms into upward-facing dog pose (urdhva mukha svanasana) or cobra pose (bhujangasana). In either cobra or up dog, avoid locking your elbows, keep your back long, and stretch the whole front of the body by gently lifting the chest. Keep your neck in line with your spine, gently stretching your chin forward without pinching your neck. Take another long breath here.
