More Sleep Helps Shed Pounds E
njoying more zzz’s is not usually asso- ciated with weight loss, but a growing number of epidemiological studies suggest that insufficient sleep may be linked to a greater risk of weight gain. The latest results from a study presented at the 2012 annual meeting of the Society for the Study of Inges- tive Behavior points out that sleep behavior influences body weight by affecting not only how many calories we consume, but also how much energy we expend. When researchers at Tübingen and Lübeck universities, in Germany, and Up-
psala University, in Sweden, investigated the effect of short-term sleep deprivation on hunger, physical activity and energy levels, they discovered that insufficient sleep increased the participants’ sensations of hunger by raising the level of the “hunger hormone”, ghrelin. The less sleep a person had, the hungrier they felt. After only one night of disrupted sleep, the volunteers moved around less and burned off fewer calories in their resting state than their counterparts that enjoyed a good night’s sleep.

WORKING OUT HOT FLASHES
ne of the most common and uncomfortable symptoms of
menopause may respond positively to a simple, no-cost measure. Health researchers at Penn State report that menopausal women that exercise may experience fewer hot flashes in the 24 hours following physical activity. In this first-time study of objective versus sub- jective, or self-reported, hot flashes, the Penn- sylvania research- ers studied 92 meno- pausal
women for 15 days.
