Health briefs: Wedlock weight

Marriages tend to work better when a man is heftier than his wife, according to a new study of 169 newlyweds. The study, published in the July issue of Social Psychological and Personality Science, tracked the couples over four years. Researchers found that when husbands had a higher body mass index than wives, husbands were more satisfied soon after vows were exchanged and wives were more satisfied over the long term than if the situation was reversed.

Beware heat ills

If you exercise or work in hot weather, beware of signs of heat-related illness, such as headache, dizziness, rapid pulse, nausea and confusion. The number of heat-related exertional injuries treated in emergency rooms more than doubled in the past decade, according to a recent study in the American Journal of Preventive Medicine. Men are more than twice as likely as women to be affected.
