In a new study, researchers found that even a short reduction in daily time spent in lying or sitting could have several cardio-metabolic health benefits for adults.
The beneficial effects could be seen in insulin level, blood lipid and glucose, and body mass index.
The research was conducted by a team at the University of Oulu in Finland.
During a 24-hour day, people spend their time in sleep, sitting or lying, and physical activities.
It is already well-established that the optimal amount of sleep for adults is 7-9 hours per night.
Current recommendations for physical activity encourage adults to engage in at least 150 high-intensity physical activity per week such as brisk walking, a workout in the gym, skiing, swimming, or running.
However, adults also spend much of their time during a 24-hour cycle in sedentary activities including sitting and lying, which is recommended to be minimized for better cardio-metabolic health. But how and how much?
The study was part of the Northern Finland birth cohort 1966 program, consisting of 3,443 participants, who underwent a clinical examination and completed extensive health and lifestyle questionnaires at the age of 46 years.
Physical activity and sedentary time were measured with an activity monitor for a period of two weeks.
The team found even 10 minutes less daily time spent in lying or sitting could be beneficial for these people’s cardio-metabolic health.
They suggest that this could be achieved by performing more high-intensity activities, or, based on these novel findings, also with accommodating more light activities on a 24-hour day.
Convenient walking, housework, shopping, cooking, easy gardening, and standing around are all examples of activities usually categorized as light intensity.
