Yoga is generally low-risk, with about 1.18 injuries per 1,000 practice hours, but it carries real downsides that rarely get airtime in a culture that treats it as universally beneficial. The risks range from overuse injuries and joint damage to rare but serious events like stroke. Whether yoga is “bad” depends on the type you practice, your body’s specific vulnerabilities, and how (or whether) an instructor accounts for them.
The Most Common Injuries
A systematic review of more than 7,400 yoga practitioners found an overall injury prevalence of about 7%. That number climbs dramatically by style: Ashtanga Vinyasa practitioners reported injuries at rates as high as 62%. Nearly two-thirds of all yoga injuries affect the lower body, specifically the hips, hamstrings, knees, ankles, and feet. Upper body injuries account for about 13%, and head and trunk injuries make up the remaining 23%.
One of the most widespread overuse injuries has earned its own nickname: “yoga butt.” This is proximal hamstring tendinopathy, an irritation of the thick tendons that attach your hamstring muscles to the sit bones. It happens when you repeatedly force deep forward folds, especially when your muscles aren’t warmed up. The hamstring tendons serve as a bottleneck, connecting large thigh muscles at a small attachment point on the pelvis. If you stretch too aggressively, a protective reflex causes the muscle to contract while you’re pulling it in the opposite direction, sending damaging tension straight into the tendon. The frustrating part is that tendons have far fewer blood vessels than muscles, so they heal much more slowly. A useful rule of thumb: if you feel the stretch in the middle of your thigh, that’s the muscle working. If you only feel a tug right at the sit bone, you’re stressing the tendon.
Wrist and Nerve Damage
Your wrists are small, complex joints built for grip and fine motor tasks, not for bearing your full body weight repeatedly. Poses like plank, chaturanga, and downward dog force the wrist into an extended position under load, increasing pressure on the small bones, ligaments, and the narrow carpal tunnel through which nerves pass. For people who already have carpal tunnel syndrome or arthritis, prolonged weight-bearing on the wrists can worsen symptoms significantly.
Nerve compression can also happen at the knee. In kneeling poses like vajrasana (a seated position with legs folded beneath you), the common peroneal nerve gets compressed where it wraps around the head of the fibula, the small bone on the outer side of your knee. Repetitive compression can slow the nerve’s ability to send signals, leading to numbness along the outer shin and top of the foot, and in serious cases, a condition called foot drop, where you lose the ability to lift the front of your foot. Documented cases in yoga instructors have shown measurable nerve damage on electromyography testing, with muscle wasting in the affected foot.
Rare but Serious Spinal and Vascular Risks
Headstands, shoulder stands, and deep backbends place extreme mechanical stress on the cervical spine. Case reports have linked these poses to vertebral artery dissection, a tear in the artery wall at the back of the neck. When the inner lining of the artery tears, blood can pool and form a clot that travels to the brain, causing a stroke. These events are rare, but they’ve been documented repeatedly in the medical literature, specifically in connection with poses involving cervical hyperextension or forceful rotation of the neck.
For people with osteoporosis or low bone density, the risks extend beyond the neck. A Mayo Clinic study identified 29 bony injuries in yoga practitioners, including compression fractures, vertebral slippage, and disk degeneration. The most harmful postures were those involving extreme flexion (rounding the spine forward) or extension (arching backward), both of which concentrate pressure on weakened vertebrae. If you have osteoporosis, these aren’t poses to “modify.” They’re poses to skip entirely.
Why Hot Yoga Pushes Your Body Too Far
Bikram and other hot yoga styles are practiced in rooms heated to about 105°F with 40% humidity. Research from the University of Wisconsin-La Crosse found that participants’ core body temperatures rose to an average of 103.2°F during a single hot yoga session. Seven participants exceeded 103°F, and one reached 104.1°F. For context, normal body temperature is 98.6°F, and typical exercise raises it to around 100 or 101. At 104°F, you’re in the danger zone for heat stroke, seizures, and vomiting.
Heat also makes your connective tissues more pliable, which feels like increased flexibility but actually means your body’s natural warning signals are muted. You can push past your safe range of motion without realizing it, particularly in the ligaments and joint capsules that don’t bounce back the way muscles do. This is a compounding problem: each session in extreme heat allows slightly more overstretching, gradually loosening structures that are meant to hold your joints stable.
The Hypermobility Trap
People with naturally flexible joints, including those with Ehlers-Danlos Syndrome, are often drawn to yoga because they’re “good at it.” This is precisely the problem. Hypermobility means your joints already move beyond the typical range due to differences in collagen structure. Your joints lack the natural brakes that tell most people they’ve reached their safe limit. Practicing yoga without accounting for this means you’re reinforcing the instability patterns that cause pain and injury in the first place.
When you consistently stretch to your maximum range, you train your nervous system to accept extreme positions as normal, even when those positions are slowly destabilizing your joints. Your muscles have to work overtime to compensate for what your ligaments can’t provide. Yin yoga, which involves long-held passive stretches, is particularly risky for hypermobile people because it targets the very connective tissues that are already too lax. Combine that with a hot yoga environment, and the problem accelerates.
Eye Pressure and Glaucoma Risk
Inversions like headstands cause a uniform two-fold increase in intraocular pressure, the fluid pressure inside your eyes. For most people, this temporary spike resolves when you come out of the pose. For people with glaucoma, it’s a different story. Elevated intraocular pressure is the most significant modifiable risk factor for glaucoma progression, and research published in PLOS One found a relationship between posture-induced pressure fluctuations and visual field loss in glaucoma patients. If you have glaucoma or are at risk for it, inversions pose a real and measurable threat to your vision.
Psychological Downsides of Yoga Culture
Yoga’s risks aren’t purely physical. The culture surrounding modern yoga can encourage a phenomenon called spiritual bypassing, where meditation, breathwork, and the language of “letting go” become ways to avoid confronting difficult emotions rather than processing them. As a defense mechanism, it looks healthy on the surface. You’re practicing self-care, cultivating mindfulness, seeking balance. But underneath, you may be using the practice to check out from feelings that need direct attention, not transcendence.
This isn’t a flaw in yoga itself. It’s a pattern in how people use it. Spiritual bypassing is, as one Psychology Today analysis put it, “an equal opportunity defense mechanism” that has more to do with what people bring to a practice than the practice itself. The risk is highest when yoga becomes someone’s only coping strategy, replacing therapy, honest conversation, or the uncomfortable work of sitting with fear, grief, or anger without trying to breathe it away.
