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.
Migraines and TIA. TIA is the short name for transient ischemic attack, which is sometimes called a mini-stroke or a warning stroke. A TIA happens because a blood clot momentarily clogs an artery. This temporarily prevents vital blood from getting to a portion of the brain. The lack of fresh blood cause symptoms to come on and then go away quickly when blood flow is restored. When the TIA is over there is no lasting, long-term brain damage that is seen with a stroke.
