With the sedentary lifestyle, keeping a laptop on our desk, watching something or typing something, or just bending our head for too long to look down at our phone can cause neck pain. Sometimes when you are travelling and do not have a comfortable train or a bus seat can also lead to a stiff neck. So what to do when you have such pain? Try these 5 yoga poses:Extended Triangle PoseThis should help relieve pain and tension in your neck, shoulders and upper back. Stand on your mat with feet hips-width apart. Turn your right toes forward and left toes out at right angle. Bring your arms up, parallel to the floor with your palms facing down. Reach forward with your right arm and hinge at your right hip. Lower your right arm and lift your left arm up towards the ceiling. Turn your gaze in any direction or do gentle neck position. Hold the pose for a few breaths, then repeat on the other side.Cat-Cow PoseIt flexes and extends the neck and allows release of tension. Begin on all four limbs and hands under your shoulders and knees under your hips. Inhale and arch your spine, look up and drop back slightly. Exhale, and turn to your right shoulder and hold your gaze, then to your left shoulder. Return to the centre and shake your head from side to side and come back. Seated Neck StretchesIt stretches and releases your sternocleidomastoid muscle. Sit down and turn your head to your right, on your right shoulder. Now, lift your chin slight, pause for 3 to 5 breaths. Feel the stretch on the left side of your neck and shoulder. Breathe. Repeat on the other side.Camel PoseIt strengthens your front neck muscles and your chin is slightly tucked and also eases tensions from your back, neck and shoulders. Begin kneeling with your knees and feet hip-width apart. Press tip of your feet on the mat. Keep your pelvis neutral. Lift your chest, arch your back and press your pelvis forward. Bring your fingertips to your heels and blocks placed on either side of your ankles.Side PlankIt is one of the optimal neck endurance exercises. Start in a seated position and bring your right forearm to the floor. Roll onto your right hip and straighten your legs. Use your feet for support. Press into your right forearm and lift your hip off the mat. Turn your gaze up or down, whatever is most comfortable to you.Pause for a few breaths and repeat on the other side.
