The heart is a muscular pump with four chambers – two atria which receive blood and two ventricles which pump out blood. The right side of the heart (right atrium and right ventricle) deals with deoxygenated blood (low in oxygen) while the left side (left atrium and left ventricle) handles oxygenated blood (rich in oxygen). There are four valves in the heart which play the vital role of preventing backward flow of blood through the heart and great blood vessels. This essentially ensures that the blood flows in one direction only. Deoxygenated blood enters the right atrium and passes into the right ventricle. It is then pumped out to the lungs where it is oxygenated. The oxygen rich blood then enters the left atrium of the heart and is passed to the left ventricle. From the left ventricle it is pushed out to the rest of the body.

The few minute of intense exercise in a week are more potent than the half-hour of routine exercise in reducing the risk of type 2 diabetes, a new study indicated.

“You can easily get health benefits of 7 to 8 minute vigorous exercise in a week if you don’t find the time to perform regular exertion. However, it is against the established perspective of the physical exertion.” Dr. James A. Timmons said.

Researchers find out those inactive young men who do only 15 min intense exercise in two weeks, develop the ability to metabolize blood glucose more efficiently. Conventional aerobic exercises may also increase insulin sensitivity in the body. The heavy exercise did the same but also directly causes reduction in the men’s bloog sugar level, this is the edge of the heavy physical work out.

A team of researchers in USA said on Friday that they have found two nonsurgical therapies effective to counter symptoms of acid reflux disease including heartburn. This therapy works for the patients who are not cured with medications.

The therapies mentioned in a recent study were published in Archives of Surgery journal.Therapies namely Full-thickness Plication and Radio Frequency Therapy include a procedure in which a long instrument; endoscope is inserted through mouth to reach the esophagus.

In full-thickness plication the endoscope is used. The in between junction of stomach and esophagus is tightened with sutures. Whereas in Radio Frequency therapy, heat is used to treat the function of in between valve of stomach and esophagus.

Joyful music and relaxing with the knowledge that your blood vessels are expanding wide open and the blood flowing freely can be quite healthier for your heart.

Dr. Michael Miller, who authored the study, says: “Often listening to music makes you feel good as well as it’s a good preventive measure for your heart health. The good thing about it is that it doesn’t have any downside as it’s simple, economic and make your heart healthy”

Dr. Carl Lavie, who is medical director of cardiac rehabilitation and prevention director of the Stress Testing laboratory, says: “It’s a short-term study, but it suggests that laughter and listening to relaxing music can prove heart-healthy. However, the question is whether regular performance of this or similar activity has long-term benefits on the cardiovascular system.”
