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.
A transient ischemic attack (TIA for short) and stroke are very similar. In fact, a TIA is also known as a transient stroke, or mini-stroke.. The difference between a TIA and stroke comes down to timing. By definition, a stroke produces symptoms that last for at least 24 hours. A TIA produces symptoms that improve after a shorter period of time (usually within 30 minutes).
