Yoga for Insomnia

Insomnia affects nearly 30% of adults, and chronic sleep deprivation is linked to increased risk of cardiovascular disease, diabetes, depression, and weakened immunity. Modern life with blue light from screens, irregular schedules, and chronic stress disrupts the natural circadian rhythm. A study in the Journal of Clinical Sleep Medicine (2020) found that regular yoga practice improves both sleep latency (the time needed to fall asleep) and overall sleep duration and quality. Iyengar yoga offers a specific approach to insomnia through restorative poses with props. These poses — in which the body is fully supported by blankets, bolsters, and blocks — activate the parasympathetic nervous system in a way that is difficult to achieve simply through "lie down and relax". The support from props allows the muscles to physically release without effort, which is the key difference. B.K.S. Iyengar devoted a significant portion of "Light on Yoga" to the therapeutic effect of pranayama (breathing practices) on sleep, emphasising that extended exhalation is the most powerful tool for calming the mind before sleep.

For the brain to fall asleep, it must transition from beta waves (active thinking) to alpha and theta waves (relaxation and drowsiness). Yoga practice accelerates this transition through several pathways. Gentle forward bends (Prasarita Padottanasana with head on support) stimulate the parasympathetic system through compression of the abdominal organs and stimulation of the vagus nerve. Legs-up poses (Viparita Karani) improve venous return and lower the pulse. Gentle muscle stretching releases physical tension accumulated during the day. The focus on breathing interrupts the "thought carousel" — the most common cause of insomnia. The key is to practise at the right time: 30-60 minutes before the desired bedtime. The practice must be gentle and restorative — no stimulating poses (strong backbends, unsupported inversions, fast sequences). The room should have dimmed lighting and a comfortable temperature.

This 30-minute sequence is designed to prepare the body and mind for sleep. Start with Tadasana (2 minutes) — simply stand with eyes closed and count 10 long exhalations. Move to Utthita Trikonasana with a tall block (1 minute per side) — slowly and without effort. Parsvottanasana with hands on a wall and head extended forward (1.5 minutes per side) — the head is at heart level, creating a calming effect. Prasarita Padottanasana with head on a chair (3-5 minutes) — this is the key pose, hold it as long as comfortable. Viparita Karani (legs on a wall with a bolster under the pelvis, 5-8 minutes) — allow the legs and mind to be completely passive. Savasana (10 minutes) — blanket over the body, eye pillow, small blanket under the knees. In Savasana, focus on extending the exhalation: inhale for 4 seconds, exhale for 8. After practice, go directly to bed without checking your phone or computer.

Yoga practice is most effective when it is part of overall sleep hygiene. Maintain a regular schedule — go to bed and wake up at the same time every day, including weekends. Avoid caffeine after 2 PM and alcohol 3 hours before bed (although it helps with falling asleep, alcohol disrupts REM sleep). Reduce blue light exposure 1-2 hours before bed. Keep the room cool (18-20°C is optimal). If you cannot fall asleep within 20 minutes, get up and do a gentle pose — Viparita Karani on the bedroom wall for 5 minutes, then return to bed. Nutritional supplements such as magnesium (300-400 mg before bed) can complement the effect of yoga practice. For chronic insomnia (longer than 3 months), consult a sleep specialist — cognitive-behavioural therapy for insomnia (CBT-I) combined with yoga produces the best results.
