What is Savasana and Why Does It Matter More Than the Rest of Your Practice?
What is Savasana,
and why it matters
Most people think of savasana as the reward at the end of class, a few minutes of lying still before they roll up the mat and get on with the day. They are missing the point entirely. Savasana is not rest. It is the most neurologically important pose in the whole practice.
What is savasana?
Savasana, pronounced sha-VAH-sah-nah, translates from Sanskrit as corpse pose. You lie flat on your back, arms slightly away from the body, palms facing upward, eyes closed. Nothing moves. It is the final posture of almost every yoga class, held for anywhere from two to fifteen minutes.
On the surface it looks like nothing. That is precisely why it is so misunderstood, and so frequently skipped, shortened, or spent planning dinner rather than actually done.
After more than fifteen years of practising and teaching, in London and in West Sussex, savasana is the pose I talk about most. It is also the one students find hardest. Not physically, but neurologically.
"Savasana is not the end of yoga. It is where yoga actually happens, where the nervous system integrates everything the practice has built."
What it does to your nervous system
Throughout a practice, particularly in dynamic styles like vinyasa or ashtanga, the body is in a state of controlled activation. The sympathetic nervous system, often called fight or flight, is engaged. Heart rate is elevated. Cortisol and adrenaline are in circulation. Muscles are contracting and releasing under load.
Savasana is the transition point. It is the moment the body shifts from sympathetic dominance to parasympathetic, the rest and digest mode that governs recovery, repair and deep relaxation. This shift is mediated by the vagus nerve, the longest nerve in the body, running from the brainstem through the heart, lungs and digestive system.
When you lie still, heart rate slows, breathing deepens, blood pressure drops and the brain begins producing alpha waves, the same brainwave state associated with meditation, creativity and the moments just before sleep. This is not metaphor. It is measurable physiology.
What it means in practice is that savasana is when the body consolidates the benefits of everything that came before it. The flexibility gains, the strength adaptations, the nervous system reset. Skipping savasana is like doing the work and refusing the payment.
The benefits
Even five minutes of conscious relaxation has been shown to reduce salivary cortisol, the primary stress hormone, measurably. Over time, regular practice lowers the baseline level throughout the day.
Parasympathetic activation has a direct effect on cardiovascular function. Blood pressure drops during the pose, and regular yoga including savasana has been found to produce lasting reductions in resting blood pressure.
The alpha brainwave state induced during savasana is the same one the brain enters moving from wakefulness into sleep. Regular practice trains the nervous system to make that transition more efficiently.
The vagus nerve acts as a brake on the fight or flight response. Strengthening vagal tone through practices like savasana builds a more resilient stress response over time.
Motor learning research shows rest periods after physical practice are essential for consolidating new movement patterns. Savasana gives the neuromuscular system time to encode what it has just learned.
Why it is harder than it looks
Most students find savasana genuinely difficult, not because of any physical demand but because of what it asks of the mind. To lie still, in silence, with eyes closed, and do nothing, is an unusual and increasingly rare experience.
The mind wanders. Planning begins. Discomfort with stillness emerges. The urge to check a phone is almost physical. This restlessness is not failure. It is simply what happens when a nervous system accustomed to constant stimulation is asked to be still. It gets easier with practice.
"The difficulty of savasana is not physical. It is the challenge of allowing the body to receive what the practice has given, without immediately reaching for the next thing."
How to get more from it
The single most effective tool I use, in my own practice and in every class I teach, is an aromatherapy eye pillow. The reasons are both sensory and neurological.
The gentle weight over the eyes activates pressure receptors in the eyelids and around the orbital bone, triggering the oculocardiac reflex, a measurable slowing of the heart rate. That alone accelerates the shift into parasympathetic mode. The darkness eliminates visual stimulation, reducing the brain's processing load. And lavender and chamomile act on the limbic system, the brain's stress regulation centre, through the olfactory pathway, the fastest route to calm in the body.
These are the eye pillows I make and use, through my own aromatherapy range at Spritz Wellness.
How long should it be?
The traditional guidance is one minute of savasana for every five minutes of active practice. A one hour class should include ten to twelve minutes. In reality most studio classes offer two to five, which is better than nothing but not enough time for the full parasympathetic shift to occur.
If you practise at home, give yourself the time. Set a gentle timer if you need to. Five minutes feels long when you first begin. After a few weeks it will feel like the most natural thing in the world, and leaving it out will feel like leaving the most important thing undone.
In short: savasana is where the practice lands. It is where cortisol falls, where the nervous system shifts, where the body integrates what movement has built. It is not a reward for getting through the hard part. It is the hard part, done differently.
If you are pregnant, rest matters even more. See the benefits of pregnancy yoga, or the Golden Thread Breath for a practice that settles the nervous system in minutes.
