Chest muscles(lengthening)

The broad muscles spanning your chest from your breastbone to your upper arm (pectoralis major and minor) receive a gentle, sustained stretch as the rib cage lifts. This extension helps to counteract the habitual rounding of the shoulders from daily activities like sitting or driving. Energetically, this opening releases tightness that can constrict the heart space, inviting a feeling of courage and emotional freedom. Regular practice helps restore optimal length, improving shoulder mobility and breathing capacity.

Front of the neck muscles(lengthening)

The muscles running from behind your ears down to your collarbones and breastbone (sternocleidomastoid and scalenes) are gently elongated as the head extends back. This passive stretch helps to release chronic tension often held in the anterior neck, which can contribute to headaches and restricted head movement. In yogic terms, this opens the throat chakra (Vishuddha), facilitating clear communication and self-expression, while also stimulating the thyroid gland. It encourages a sense of release in the often-overworked muscles responsible for holding the head forward.

Hip flexors(lengthening)

The deep muscles connecting your lower back and pelvis to your inner thigh (iliopsoas) are subtly lengthened as the spine extends and the legs remain flat on the floor. While not as intense as other hip-opening poses, this gentle traction helps to release the chronic shortening often seen in these muscles from prolonged sitting. Releasing the iliopsoas can alleviate lower back pain and improve pelvic alignment, allowing apana vayu (downward energy) to flow more freely, grounding the practitioner. This gentle unwinding promotes a feeling of ease through the entire anterior chain.

Neck Injury / Cervical Issues

Looking up, bearing head weight, or unsupported neck rotation can compress cervical vertebrae and irritate nerves.

Do not allow the head to drop back unsupported; keep the chin slightly tucked and look forward rather than up.

High Blood Pressure

Vigorous effort and inverted positions temporarily raise blood pressure in the head, increasing strain on blood vessels.

Limit the depth of the backbend, breathe smoothly, and avoid holding the pose for extended periods.

Headache / Migraine

Physical exertion, inversions, and strong breath work can intensify an existing headache or trigger a migraine.

Avoid inversions and strong pranayama; rest in a supported, restorative posture with a cool cloth on the forehead.

Insomnia

Stimulating pranayama and energising poses can activate the sympathetic nervous system, making sleep harder if practised late in the day.

Practise calming, exhalation-focused breath work; avoid stimulating postures or pranayama close to bedtime.
