Team sport lowers blood pressure in postmenopausal women
Team sport effectively counteracts diminished vascular function in women with high blood pressure, even several years after the onset of menopause. Estrogen loss associated with transition into menopause increases women's risk of developing cardiovascular disease and reduces their ability to benefit from training. However, a new study from the Center for Team Sports and Health at the Department of Nutrition, Exercise and Sports, University of Copenhagen demonstrates that postmenopausal women do benefit from playing small-sided floorball twice a week.

Abnormal blood pressure levels while sleeping increase risk of heart disease, stroke
Nighttime blood pressure levels that are higher than daytime levels, as well as a pattern of blood pressure rising at night (rather than decreasing slightly), were associated with higher risk of cardiovascular disease and heart failure. Even when blood pressure is well controlled during the day, patients who experienced extreme dips in their blood pressure while asleep had a significantly greater risk of stroke compared to those who had normal blood pressure while sleeping.
