Shirodhara involves pouring warm oil in a slow, steady stream across your forehead for half an hour or more. Described like that, it sounds closer to a ritual than a treatment, and I understand why people raise an eyebrow. Yet when researchers have measured what happens in the body during a session, they have found real changes in the chemistry of stress. The studies are small, and I’ll be clear about their limits, but the physiology turns out to be more concrete than the description suggests.
What shirodhara is
The name comes from two Sanskrit words: shiro, meaning head, and dhara, meaning a stream or flow. Shirodhara belongs to Ayurveda, the traditional medicine of India, which uses it to settle an overactive, restless mind.
You lie on your back on a treatment couch. Above your head, a vessel releases warm oil, traditionally sesame oil and often infused with herbs, in a thin, continuous stream onto the centre of your forehead. The stream moves slowly from side to side, and the oil runs back over your scalp and into your hair. In my clinic the pouring lasts 30 to 45 minutes. You have nothing to do except lie still.
The Ayurvedic view
Ayurveda describes the point between and just above the eyebrows as a marma, one of the body’s vital points, and yogic tradition links the same spot to the ajna, or third eye. In Ayurvedic terms, a racing mind, poor sleep and anxiety often reflect an excess of vata, the principle associated with air and movement. The warmth, weight and steady rhythm of the oil aim to counter that, bringing heaviness and stillness where there is too much movement.
I find this framework useful, in much the same way I find the Five Elements useful: it describes patterns that people recognise in themselves. It remains a traditional model, though, and the research tells us something narrower.
What the research has measured
The most detailed study came from the University of Toyama in Japan. Uebaba and colleagues, writing in the Journal of Alternative and Complementary Medicine in 2008, used a robotic system to deliver shirodhara with sesame oil under controlled conditions. In a randomised, controlled experiment with 16 healthy women, they compared 30 minutes of shirodhara with 30 minutes of lying in the same position without it. After shirodhara, compared with lying still, the women showed:
- lower anxiety scores
- higher scores on a questionnaire that measures altered states of consciousness, including a trance-like absorption
- a larger fall in noradrenaline, a chemical messenger of the body's fight or flight response
- warmer feet, a sign of better circulation to the skin, which tracked with how much their anxiety fell
The authors concluded that shirodhara eases anxiety and damps down the body’s stress response. They also found that the more deeply someone sank into that absorbed state, the further their anxiety fell.
A second study, from Okayama University in 2016 (Tokinobu and colleagues, in the same journal), looked at sleep. Twenty people with sleep problems had seven 30-minute sessions over two weeks with sesame oil and, after a gap of at least two months, the same course with warm water, in random order. Fifteen completed the study. After the sesame oil course, people rated their sleep quality better than after the water course. The study found no benefit for daytime sleepiness, though, or for sleep measured by a monitoring device.
In 2015 the Malaysian Ministry of Health’s health technology assessment team reviewed the evidence. They found seven small studies, concluded that there was very limited evidence that shirodhara reduces anxiety, insomnia and mental stress, and pointed out that the studies were too short to show any long-term effect. They also noted that some participants reported headache, chills or other discomfort under extreme test conditions.
Taken together, these studies show measurable relaxation and some promising early findings on sleep, but the evidence remains too thin to call shirodhara a treatment for anxiety or insomnia. I offer it for deep rest and a calmer mind. If you’re living with persistent anxiety, low mood or insomnia, please talk to your GP as well, and think of shirodhara as something that can sit alongside that care.
Why it feels the way it does
Most bodywork keeps changing: hands travel, pressure shifts, one area follows another. In shirodhara the sensation stays almost the same from one minute to the next, with the same warmth, the same weight and the same slow sweep across the forehead. With nothing new to follow, attention tends to settle on the sensation itself, and the usual stream of thought often slows and fades.
Nobody has yet shown exactly why this happens, and I’d be wary of anyone who claims to know. That explanation is consistent with the Toyama findings, though, and with the stillness Ayurveda sets out to create.
Before and after a session
A few practical points help you get the most from it.
- Mention any allergies beforehand, especially to sesame or nuts, along with any scalp or skin condition, a recent head or neck injury, and whether you're pregnant or currently unwell.
- Expect oily hair. You can leave the oil in for a few hours and wash it out at home. Applying shampoo to dry hair first, before you add water, makes this easier, and a hat or scarf helps on the way home.
- Give yourself time afterwards. You may feel drowsy and slow for a while, so avoid booking anything demanding straight after, and wait until you feel fully alert before you drive.
For people whose minds rarely stop, half an hour of lying still under a stream of warm oil can be a real relief. The early research suggests that the body’s stress response settles along with the mind, which is a good reason to take this old treatment seriously while we wait for larger studies.
