Is Sitting Really The New Smoking?
You may have heard the media headlines that 5 or more hours of sitting is the new smoking, but is this really true or is it just another sensationalist headline?
Office workers spend 70-85% of their time sitting at work which means they are currently one of the most sedentary populations. Even when adults meet the physical activity guidelines, sitting for prolonged and unbroken periods of time has been associated with an increased risk of heart disease, diabetes and even weight gain 1, 2.
What’s more, a recent systematic review and meta-analysis which included 1184 participants showed that if a 65kg person were to substitute sitting with standing for 6 hours per day they would expend 54 more calories each day which would translate to a fat loss of 2.5kg in one year 4. People who sit for long periods of the day have been shown to have a higher rate of diabetes and cardiovascular disease and this risk is increased irrespective of weight gain.
What’s more, sitting for extended periods of time cooped up behind a dark desk may negatively affect mental health and moral. Research has shown that fresh air and nature are associated with greater vitality which is why exercise such as walking meetings can even improve mood and even self-esteem. What’s more, exposure to daylight can increase the production of our happy hormone serotonin, and is particularly important for those suffering from seasonal affective disorder (SAD) 4, 5.
Whilst it’s too early to put sitting and smoking within the same bracket, there is a wealth of research to support the benefits of sitting less. Research published in the British Medical Journal (BMJ) found that sit-stand workstations could improve markers of health and even boost work performance. These height-adjustable stations were implemented in the trial which involved 146 NHS staff. Over a 12 month period, results showed an improvement in job performance, work engagement, occupational fatigue, presenteeism, daily anxiety and quality of life 3.
