'Heartbreak': How Rejection Literally Stops Your Heart


Heartbreak is not a myth or some mystical notion devised by grieving lovers. A new study has proven once and for all that heartbreak is a real physiological phenomenon—the one that makes one’s heart stop, literally. Your levels of cortisol, a stress hormone, fluctuate when you think you're being rejected.

It really can have a physical effect, scientists have found. The study is published in Psychological Science, a journal of the Association for Psychological Science. A Noida based physician and head of Redix Hospital, Dr.Ravi Malik says that many young boys and girls visit him in order to address their `ailment`. “After failure in love, they feel very sad and dejected. They deserve pep talk," Dr.Malik concludes.

The effect on the nervous system explains why some of us find ourselves unable to eat or sleep after a break-up. And the more rejected we feel, the slower the heart rate becomes, a joint study by scientists at the University of Amsterdam and Leiden University in the Netherlands has found. To test the theory the researchers asked a group of volunteers to take part in an experiment which, unbeknown to them, tested their heart rate when rejected by others. First the participants were asked to send in photos of themselves.

They were told that for a study on first impressions, students would look at the photo to decide whether they liked the volunteer. This was just a cover story for the real experiment. Each volunteer then had wires placed on their chest for an electrocardiogram, was shown a face on screen and was then asked to guess whether that student liked them.

Each participant’s heart rate fell in anticipation before they found out the person’s supposed opinion of them. Heart rate was also affected after they were told the other person’s opinion. If they were told the other student did not like them, the heart rate dropped further, and was slower to get back up to the usual rate. `Unexpected social rejection could literally feel `heartbreaking, ` as reflected by a transient slowing of heart rate, ` the researchers said.

Like most Psychological Science articles, this one suggests no antidote to the physical problems associated with rejection. But the findings help explain how evolution programs human sociability. We are meant to find comfort in one another — through chemical means, if necessary — and not to be loners.

If you ever find yourself suffering from heartbreak, therefore, comfort yourself with knowing that while the pain is real, it is only transient in nature.

Findings About Breast Cancer


This is my own research to find out what research is being done about the scourge. Well, this is what i found out.

A Breakthrough in Breast Cancer! Breast cancer vaccine was found to be successful in mice and researchers are anxious to start testing it on human patients. The vaccine did not only breast cancer tumors but also stalled the growth of already existing tumors.

An old drug used in treating blood cancers may help fight aggressive breast cancer {triple negative breast cancer}.

Broccoli and Brussels sprouts have been proven to contain cancer-fighting components. Research showed that these super-foods contain a substance that breaks down a cancer-causing molecule.

Women who drank Scandinavian boiled coffee more than four times a day, compared to women who drank less than one cup a day, have a lower risk of developing the disease.

A new method for treating breast cancer may help scores of patients beat the disease without experiencing debilitating side effects, according to BBC News. Scientists are attempting to target the genetic makeup of tumors and kill it without damaging other healthy cells.

A new study out of the Washington University School of Medicine suggests that a bone-strengthening drug may also help fight off metastatic breast cancer.

A new chemotherapy drug has shown some real progress in the fight against the disease. The drug, called Bavituximab, is an antibody that is specifically designed to build a patient's immune system. It cures the disease by fighting off tumors and its blood vessels.

Study ties tumor cells to breast cancer survival. A new study has revealed that the number of tumor cells circulating in the blood of metastic breast cancer patients does affect their survival, reports BusinessWeek.

Bitter melon extract, which is a popular dietary supplement, may eventually become a preventative treatment for breast cancer. Findings suggest that bitter melon extract . . . Induces breast cancer cell death," said lead researcher Ratna b. Ray.

Vitamin D might even be beneficial in the fight against breast cancer. It is recommended that individuals eat a diet rich in foods such as fish, milk and eggs to ensure optimal vitamin D absorption, and make sure that they have enough exposure to sunlight on a daily basis.

A lot of research is going on around the world to discover the cure for cancer and to also make life easier for terminally ill patients.
Let’s hope the cure is found soon enough!

To women fighting breast cancer, please do not lose hope!
