As the director of Orange County California-based Walker Physical Therapy & Pain Center, occupational and physical therapist, and nutritionist, Dr. Grace Walker offers wellness advice to her patients and through her practice’s blog. Physical therapist Dr. Grace Walker believes strongly in the power of movement and cautions against a sedentary lifestyle. According to ABC News, a number of Americans currently spend as much as 15.5 hours daily in a sitting position.
In fact, Dr. Hidde van der Ploeg and the University of Sydney in Australia have found that 11 or more hours of daily sitting can lead to a 40 percent increase in one’s risk of death.
Physiology supports such a claim. When the lower half of the body is still, the brain receives signals to increase blood sugar and decrease its reliance on stored fat for fuel. At the same time, metabolism reduces to less than 34 percent as compared to periods of activity. Data also suggests that every two hours of sitting correlates with a 7 percent increase in diabetes risk, while this sedentary time also contributes to the weakening of spinal support muscles and tightening of the hamstrings and hip flexors. It seems that only a lifestyle that incorporates regular standing and moving can mitigate these risks and help the body’s systems work optimally.
