The COVID-19 pandemic not only removes the person’s life but also damages the day-to-day chores of the person. The lockdown in various countries has resulted in limited movement and makes them idle in the home for several months. Most of the people work from home by sitting in one place, and students sit in Zoom for countless hours, spending their time only on the internet and television with no physical activity. The harmful effects of too much sitting are cardiovascular problems, type 2 diabetes, cancer as per certain studies.
Some questions arose whether reclining is better or not than sitting upright, and the unexpected answer is no. The physiologist says it should be called sedentary behavior, which is more equivalent to waking behavior. It requires minimal usage of energy like in case of sitting, reclining according to 2018 Physical Activity guidelines.
How much physical activity is important
A person should either indulge in moderate physical activity for 60 to 75 minutes or do vigorous workout for 30 to 40 minutes in a day. A study in 2016 showed that the people who sat a lot had a great risk of mortality. And those people who underwent moderate or vigorous physical activity had the least risk.
Physical activity is all about the expenditure of energy, and this happens when we walk in the home or do works in movements. Exercise is a type of physical activity used to flex the muscles and provide balance to the person. It also promotes cardiovascular coordination. The effects due to the exercise include a lower chance of getting some metabolic disorder and also improves the brain by reducing dementia, stress.
However, the above said sedentary behavior doesn’t fit for sleep. While sleeping, our body slows down, but it also enters the repair mode. The harmful metabolites in the brain are taken away by the Glymphatic system during sleep. Sleep deficiency results in dementia, suicide, depression, stroke, high BP, and also promotes obesity. This is because it increases the ghrelin level (The hunger hormone), which leads to more food intake.
Especially for children, sleep is important (9 to 12 hours) as it increases the Growth Hormone (GH) level in the blood, which makes them grow stronger. So, everyone engage yourself in physical activity, workout by yourself, sit for less time, and improve your memory.
