What is the best time of day to exercise for heart health?

Morning physical activity is associated with the lowest risk of heart disease and stroke, according to a study in more than 85,000 individuals published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology. The findings were consistent regardless of the total amount of daily activity.

“It is well established that exercise is good for heart health, and our study indicates that morning activity seems to be most beneficial,” said study author Ms. Gali Albalak of Leiden University Medical Center, the Netherlands. “The findings were particularly pronounced in women, and applied to both early birds and night owls.”

The study used data from the UK Biobank. It included 86,657 adults aged 42 to 78 years who were free of cardiovascular disease at baseline. The average age was 62 years and 58% were women. Participants wore an activity tracker on their wrist for seven consecutive days. Participants were followed for incident cardiovascular disease, which was defined as the first hospital admission or death related to coronary artery disease or stroke.

During six to eight years of follow up, 2,911 participants developed coronary artery disease and 796 had a stroke. Comparing peak activity times across a 24 hour period, being most active between 8 am and 11 am was linked with the lowest risks of both heart disease and stroke.

In a second analysis, the investigators divided participants into four groups based on the peak time of physical activity: 1) midday; 2) early morning (~8 am); 3) late morning (~10 am); and 4) evening (~7 pm). The categories were selected according to peak times of activity in the study population, rather than being predetermined before the study began. Associations between peak time of activity and incident cardiovascular disease were analysed using midday as the reference group.

    Interesting BUT don’t get bogged down with details. Just move and sweat a little most days! As Tony says, “Eat less. Move more.” You’ll be fine.

    This is an interesting finding. I prefer exercising in the morning because it is a great day to start the day. Also the longer in the day I wait, the easier it is to come up with excuses!
