De plus,
He and student research assistants Kimberly Fairbrother and Ben Cartner tracked blood pressure levels and sleep patterns of individuals ages 40 to 60, who exercised moderately for 30 minutes, three times a week. The research volunteers walked on a treadmill at 7 a.m., midday (1 p.m.) and in the evening (7 p.m.).
In all cases, those who exercised at 7 a.m. experienced about a 10 percent reduction in blood pressure that carried through the remainder of the day. They also had about a 25 percent dip in blood pressure at night, slept longer and had more beneficial sleep cycles than when they exercised at other times of the day..
