Importance of Exercise

Humans, like other animals, are designed for movement. Our bodies are meant to walk, run, and engage in physical activities. Our ancestors walked long distances while hunting, gathering food, and moving to new places. Their nomadic lifestyle played a crucial role in keeping them physically fit.

When we don’t move enough and lead sedentary lives, we can experience negative effects like low energy and weight gain. Sitting for too long can be risky for our health. It increases the chances of obesity, heart problems, and high cholesterol. It can also cause back pain, bad posture, and even contribute to diabetes and poor mental health. To stay healthy, it’s important to take breaks, move around, and exercise regularly.

Author Kelly McGonigal mentions about “Runner’s high” in her book, “The Joy of Movement”. It is a state of euphoria or deep relaxation that occurs after intense workouts, especially in activities like running. It was initially believed to be caused by endorphins, the “feel-good” chemicals released during exercise. However, recent research suggests that endocannabinoids, specifically anandamide, may also play a role. Thus, both endorphins and endocannabinoids contribute to the pleasurable effects of exercise. Kelly highlights the importance of collective actions, such as dancing or walking together as they create a stronger bond and bring joy. Similar behavior can be observed in animals like chimpanzees, baboons, and gorillas, who groom each other to strengthen their social ties. The act of social touch releases endorphins, making their relationships stronger. Sharing food and providing support during conflicts further strengthens their bond.

Prominent neuroscientist and author, Wendy Suzuki has conducted extensive research on the effects of exercise on the brain. Suzuki’s research suggests that exercise can enhance memory and cognitive abilities. She explains that aerobic exercise, in particular, promotes the growth of new neurons in the hippocampus, a brain region critical for memory formation. Regular exercise improves both short-term and long-term memory, leading to better learning and retention. She explains that exercise promotes neuroplasticity. This plasticity is vital for maintaining brain health and resilience, particularly as we age. Physical activity increases the release of neurotransmitters like norepinephrine, which play a role in regulating attention and focus. Performing exercise before engaging in mentally demanding tasks can improve concentration and productivity.

Remember to exercise in moderation for a healthy approach. Find a balance that suits your fitness level and goals, listen to your body, and avoid pushing yourself too hard. Consistency and sustainability are key for long-term benefits and injury prevention.
