To Heal or Not to Heal

Comparison of blisters on stressed individual and non-stressed individualSmall differences in marital strife made big differences in the healing time.

Most people think a good marriage will make you happy. But can a good marriage keep you healthy, as well? In "To Heal or Not to Heal," researchers at Ohio State University explore links between the psychological health of a marriage and the physical health of the couple.

Exposure to New Experiences Rewarding

Exposure to New Experiences Improves Memory And Could Help Treat Memory Problems

Could this research help explain the Coolidge Effect too? And why we need to keep our intimate relationships rewarding by (1) reinforcing positive, oxytocin-producing contact, and (2) avoiding dopamine fluctuations brought on by sexual satiation?

new rewards...Dr Duzel said: "When we see something new, we see it has a potential for rewarding us in some way. This potential that lies in new things motivates us to explore our environment for rewards. The brain learns that the stimulus, once familiar, has no reward associated with it and so it loses its potential. For this reason, only completely new objects activate the midbrain area and increase our levels of dopamine."

NEW YORK (Reuters Health) - The manner in which husbands and wives argue over such hot-button topics such as money, in-laws, and children, may be a factor in their risk of developing coronary atherosclerosis, or hardening of the arteries of the heart.

Parallels to sex?

ATLANTA, Dec. 11 (UPI) -- The pleasure of shopping is chemical -- and fleeting -- it's all about the means and not the ends, say U.S. scientists.

The surge of excitement from shopping involves dopamine, a chemical associated with pleasure. As shoppers first see a product and then consider buying it -- the anticipation rather than the buying itself -- discharges the chemical and drives the process, reported the Sunday Telegraph.

However, this surge of pleasure drops sharply as soon as the product has been bought, which can result in a sense of let-down -- or "buyer's remorse" -- shortly afterwards.

Study suggests infidelity could be part of evolutionary call for desirable mates

Women who feel an urge for sex outside of their marriages might be hearing an evolutionary call to improve the species.

New research suggests that during ovulation, when women are ready to conceive, nature may encourage them to look beyond their male partners for a better gene pool, but only if they don't find their mates sexually attractive.
