    Should You Put Antiperspirant On at Night? What Experts Advise

    Most of us put antiperspirant on after a morning shower.

    Sleep Apnea After Menopause: Why the Risk Rises, What Studies Found

    Snoring, morning headaches and daytime sleepiness after menopause often get blamed on hormones alone. But in a Wisconsin sleep-lab study of 589 women, postmenopausal women had 2.6 to 3.5 times the odds of sleep-disordered breathing, even after accounting for age and weight.
