Final answer:
Sitting has been linked to higher mortality in humans, with prolonged periods of being sedentary associated with increased health risks and chronic diseases.
Step-by-step explanation:
The activity that has been linked to higher mortality in humans is sitting. Extensive research indicates that long periods of sitting can have various negative health effects, including an increased risk of chronic diseases like obesity, heart disease, and diabetes, which can lead to a higher mortality rate. While standing up from a seated position is an action of physical movement, and activities such as walking, sprinting, and running generally contribute to better overall health and fitness, prolonged sitting is the one associated with negative health outcomes.
Studies have shown that individuals who spend the majority of their day sitting are at a higher risk of developing chronic conditions and experiencing premature death compared to those who engage in regular physical activity. It's important to incorporate regular movement and exercise into our daily routines to promote overall health and reduce the risk of mortality.
