Atherosclerosis: Stress, Lack Of Sleep & Exercise And Poor Diet Raise Risks

Swirski acknowledged that “there is no question” that genetics play a role in cardiovascular health, but in the last several years, four risk factors — stress, sleep interruption or fragmentation, diet, and sedentary lifestyle — have been clearly identified as contributing to atherosclerosis, commonly referred to as hardening of the arteries, which can lead to a variety of complications, including death.

Exercise: The Evolution Of Human Physical Activity

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species?

Herman Pontzer explores the evolution of human metabolism and its role in our evolution and health. From an evolutionary perspective, life is a game of turning energy into offspring. The strategies that species use to acquire energy, in the form of food, and allocate energy to the essential tasks of growth, maintenance, movement, and reproduction, are incredibly diverse and reflect the ecological pressures and opportunities encountered. There is a deep evolutionary history of the human metabolic strategy and our divergence from other apes.
