March 23, 2011 -- Regular exercise and a low-sodium diet are two lifestyle changes that are often recommended to lower high blood pressure.

Now a new study shows that one appears to influence the other.

Specifically, physical activity appears to help keep blood pressure from climbing after people eat eye-popping amounts of salt -- 18,000
milligrams a day to be exact. That’s about 10 times the recommended
daily intake for sodium. As a visual aid, picture 18 salted soft
pretzels like the kind sold at mall food courts.

March 28, 2011 -- Rejection really does hurt. That’s the message of a new study that suggests physical pain and the pain of rejection may “hurt” in the same way.

Researchers found that physical pain and intense emotional pain,
such as feelings of rejection after a bad breakup of a relationship,
activate the same “pain” processing pathways in the brain.

"These results give new meaning to the idea that social rejection
'hurts,'" says researcher Ethan Kross, PhD of the University of
Michigan, in a news release.
