Where it comes from

Ruesi dat ton (ฤๅษีดัดตน) means roughly 'hermits stretching themselves'. A ruesi is a hermit or sage (rishi), and the exercises are traditionally shown as postures performed by these figures. One account links the stretches to relieving the body after long periods of meditation.

The best-known record is at Wat Pho (Wat Phra Chetuphon) in Bangkok. King Rama III, who renovated and enlarged the temple from 1832, commissioned 80 hermit statues in exercise positions, each said to relieve particular ailments, and had the postures recorded in illustrated verse (khlong) on Thai folding books; a Thai stamp catalogue dates this book to 1838. The statues were made of stucco and, according to K.I. Matics (1977), only around 18 survive. A 2021 study by art historian Orawan Chueanoi dates the oldest group of statues to the early Rattanakosin period.

Wat Pho's stone inscriptions (1831–1841), which preserve a wide range of Thai knowledge including massage texts, were registered by UNESCO in its Memory of the World programme in 2011. Today the Department of Thai Traditional and Alternative Medicine (Ministry of Public Health) promotes a simplified set of 15 basic postures for the general public.

The principle

Ruesi dat is a form of Thai traditional self-care: slow stretching postures performed by oneself, without equipment, linked to the breath. Each traditional posture carries a name describing the discomfort it was meant to ease, for example tiredness, chest tightness or stiff shoulders.

Thai researchers describe the practice as built on the relationship between posture, movement and breathing: you breathe in and out deeply and slowly while moving into a posture, hold it briefly, then release. It is a low-intensity activity that can be done standing, sitting or lying down.

What people come for

Stretching stiff muscles, for example after sitting or driving for a long time
Gentle daily exercise that needs no equipment
Calm, slow breathing and relaxation
Staying mobile with age
Discovering a part of Thai cultural heritage

How it works on the body

Ruesi dat combines slow stretches and gentle self-pressure with deep breathing, moving each part of the body in turn.

A session, step by step

01
Preparation
Sit or stand comfortably, relax the shoulders and take a few slow breaths.
02
Enter the posture
Move slowly into a stretch while breathing in, for example interlacing the hands and pushing the arms forward.
03
Hold briefly
Hold the stretch for a moment without forcing, keeping the breath calm.
04
Release
Return slowly to the starting position while breathing out.
05
Repeat and change sides
Repeat each posture a few times (around 5–10 in public-health guidance) and on both sides, then move on to the next posture.

Precautions

Move slowly and stay within a comfortable range: stretches should never be painful. Some traditional postures are complex and are often simplified for beginners, older people and children.
If you have a recent injury, joint replacement, osteoporosis, or neck or back problems, ask a doctor or a Thai traditional medicine practitioner which postures suit you.
Avoid holding the breath during effort, especially if you have high blood pressure or a heart condition; stop if you feel dizzy.
During pregnancy, check with your health professional first and avoid postures that press on or twist the abdomen.
Research on ruesi dat is still limited (mainly small Thai studies), so it should be seen as gentle exercise, not as a treatment, and should not delay seeing a doctor.

Complementary practice: does not replace medical advice.

In Thailand

Ruesi dat is part of Thai traditional medicine and is promoted by the Department of Thai Traditional and Alternative Medicine of the Ministry of Public Health, which has publicised a set of 15 basic postures and, for example, recommends a few simple postures to travellers during Songkran. It is taught in Thai traditional medicine courses, community health groups and some temples and spas; the hermit statues can still be seen in the grounds of Wat Pho in Bangkok. Thai universities have run small studies, for example a three-month programme with older adults in Ubon Ratchathani that reported better quality-of-life scores, but these studies are small and uncontrolled.

Frequently asked questions

Is ruesi dat the same as yoga?

It is sometimes called 'Thai yoga' because both use postures and breathing, but ruesi dat is a Thai tradition with its own history, recorded at Wat Pho and promoted today by Thai traditional medicine.

Do I need a class to learn it?

Simple postures can be learned from official Thai public-health materials and done alone. A class or a Thai traditional medicine practitioner is useful to learn more complex postures safely or if you have health problems.

Can I see the hermit statues?

Yes, a number of the hermit statues remain in the grounds of Wat Pho in Bangkok, though many of the original 80 have been lost.

Is there scientific evidence?

Only limited evidence so far: mostly small Thai studies without control groups, for example on quality of life in older adults. It is best viewed as gentle exercise and a cultural practice.
