The 8-8-8 rule — splitting your day into sleep, work and rest may extend your life

The 8-8-8 principle divides the day into three equal parts: eight hours of sleep, eight hours of work, and eight hours for physical activity, relationships, rest and daily tasks. Contemporary research suggests this model can benefit heart health, brain function and longevity. Experts highlight that the approach requires no expensive supplements or restrictive diets.
