While we’re on the topic of exercise and your health, let’s turn our attention to sitting—one of the many enemies of good health.In addition to reaching the recommended amount of daily active time, it’s also important to reduce the amount of sitting you do. You may already know that excessive sedentary time —time spent sitting or lying down— is a physical health menace, increasing the risk of heart disease, diabetes, and other chronic illnesses. But did you know that sedentary behavior is a threat to neurological health as well? Sedentary behavior is associated with lower cognitive performance and may also affect parts of the brain that are critical to memory. When you do have to sit for along time, give yourself a 2-minute walking break every 30 minutes to get blood flowing properly to the brain.
