I often joke with my husband that most people ought to have square eyes as they spend so much time either in front of the TV or the computer screen. Some people I know easily spend a minimum of 6-8 hours daily just slouched before the goggle box. Often, they’re not even watching any television programs, but snoozing.

Call me restless, but sitting still throughout a TV show is a challenge for me, let alone indulging in TV marathons. The minute the commercial break comes on, I like to get up to do something active and productive, such as washing the dishes and tidying up. Given a choice between watching TV and going for a walk, I choose the walk every time. Unless the program is really educational or inspiring, it seems like such a waste of life to spend hours in front of the television set.

I had a really nice walk yesterday when I visited my sister-in-law’s resort home. While everybody else stayed indoors to – you guessed it – watch TV, I enjoyed a lovely, invigorating walk along the coastline. The weather was cool and the sea breeze was refreshing. There were many interesting plants, trees and flowers to discover along the way, as well as beautiful homes to admire. Of course, I sometimes stopped to pat the occasional cat or dog. Gazing across the sea into the distance was a good break for my eyes, accustomed as they are to near-sight activities like reading and working on the computer. The setting sun also gave me my daily dose of Vitamin D as well as therapeutic far infrared rays. What a wonderful, rejuvenating walk that was!

In January, a six-year Australian study reported that living a sedentary lifestyle can shorten your life. Surprise, surprise. Researchers from the Baker IDI Heart and Diabetes Institute in the state of Victoria traced the lifestyle habits of 8,800 adults aged 25 and older. They found that each hour spent in front of the TV daily increased the risk of dying earlier from cardiovascular disease. Published in Circulation: Journal of the American Heart Association, the study found every hour in front of the TV was associated with an 11% increased risk of death from all causes, a 9% higher risk of cancer death, and an 18% increased risk of death related to cardiovascular disease (CVD).

The researchers said: “Compared with people who watched less than two hours of television daily, those who watched more than four hours a day had a 46% higher risk of death from all causes and an 80% increased risk of CVD-related death”. They said this association held regardless of other independent and common CVD risk factors, including smoking, high blood pressure and cholesterol, unhealthy diet, excessive waist circumference and leisure exercises.

The findings suggested that any prolonged sedentary behavior, such as sitting at a desk, may pose a health risk. Said researcher Professor David Dunstan, head of the institute’s physical activity laboratory in the division of metabolism and obesity: “The human body was designed to move, not sit for extended periods of time. For many people, on a daily basis, they simply shift from one chair to another – from the chair in the car to the chair in the office to the chair in front of the television set.”

These findings applied not only to the overweight but also to those of a healthy weight: “Even if someone has a healthy body weight, sitting for long periods of time still has an unhealthy influence on their blood sugar and blood fats. In addition to doing regular exercise, avoid sitting for prolonged periods and keep in mind to ‘move more, more often’. Too mush sitting is bad for health.”

I’m off to walk my dog now!
