yoga
Meaning of yoga: What a yoga study measures depends on the style tested, since a restorative class and a heated flow class share little beyond the name.
Definition of yoga
Yoga is a practice combining physical postures, breath control and meditation, developed in India and now used worldwide in many forms. Styles range from slow restorative sessions supported by props to fast, physically demanding sequences. Within healthcare it is studied and offered as a complementary practice, most often for stress, sleep, balance and long-standing pain.
What does a practice consist of?
Three elements recur in almost every style, in different proportions. Postures, held or flowed between, provide the physical loading and the work on balance and flexibility. Breath control regulates the rhythm and depth of breathing, and it is the component most often linked to the effect on stress, since slow breathing shifts the balance of the nervous system toward its resting side. Meditation or focused attention completes it. Removing any one changes what the practice is, which is why yoga is classed as a mind-body exercise rather than as stretching.
How do the styles differ?
| Style | Emphasis |
|---|---|
| Hatha | Slower, posture by posture, a common introduction |
| Vinyasa or flow | Continuous movement linked to breath; more aerobic |
| Iyengar | Precise alignment, long holds, props such as blocks and straps |
| Restorative and yin | Few postures, supported and held for minutes at a time |
| Hot styles | Practiced in a heated room, which adds cardiovascular strain |
What is it used for, and what are the risks?
Research is strongest for stress, anxiety, sleep quality and long-standing low back pain, where it performs comparably to other structured exercise. It is also studied for balance in older adults and for fatigue during cancer treatment. Evidence is weaker or absent for many broader claims. Modified programs overlap with physical therapy, and the meditative component overlaps with practices such as transcendental meditation. Injuries do occur, most often to the wrists, shoulders, knees, hamstrings and lower back, usually from forcing a position; and inverted postures, deep spinal extension and heated rooms interact with conditions such as glaucoma, uncontrolled high blood pressure and recent joint surgery.
Used in a sentence

Good to know
Yoga is generally studied and used as a complementary practice alongside standard medical care rather than as a replacement for it, a distinction that affects how its role in a treatment plan is generally understood.
