The study did not focus on the calorie-burn of yoga, but rather on the way yoga influenced eating habits. In a survey of over 15,000 participants, researchers found that people who participated in a minimum of one 30 minute yoga session once a week either maintained or lost weight over a 10 year time frame.
A transient ischemic attack (TIA) occurs when blood flow to a part of the brain stops for a brief time. A person will have stroke-like symptoms for up to 24 hours. In most cases, the symptoms last for 1 to 2 hours.
It is important to know that: 1  A TIA is a warning sign of a future stroke. 2  A TIA is a medical emergency, just like a major stroke. 3  Strokes and TIAs require emergency care. 4  There is no way to know in the beginning whether symptoms are from a TIA or from a major type of stroke. 5  Like ischemic strokes, blood clots often cause TIAs.
