Patients with dizziness and nausea in yoga practice mainly consider the following reasons: firstly, it may be caused by improper posture of patients, which is generally related to patients with cervical spondylosis, when improper posture may lead to the protruding cervical discs compressing the vertebral artery, which will cause patients to have insufficient blood supply to the brain, and patients will have dizziness and nausea. The third aspect is that the dizziness and nausea of patients practicing yoga may be caused by excessive exertion, sweating and failure to replenish water in time, which may lead to a decrease in effective blood circulation and dizziness and nausea, or low blood sugar caused by heavy activity, which may also cause dizziness and nausea.
