Editorial | Children are in need of less screen time

There is growing consensus in society that excessive use of mobile phones and tablets is harmful to health, but that does not stop people of all ages from fiddling with such gadgets. Chances are that you are also one of those who are hooked on their screens. However, even more disturbing is the fact that some parents have been using them as babysitting devices, thereby exposing future generations to possible addiction and health risks.

In a belated move, the World Health Organisation has issued guidelines for the first time in this respect, and it has said that those under the age of two should not be exposed to mobile phones and tablets at all. The screen time for children aged between two and five should be limited to no more than an hour a day, the less the better. The directions were developed as part of broad guidance on physical activity, sedentary behaviour and sleep for children.

It does not take a paediatrician or optometrist to show prolonged screen time harms the growth of children, in particular their eyesight and brain development. Yet it says something about the severity of the problem when the WHO needs to weigh in with advice. Increasingly, it is not uncommon to see infants being entertained with such devices. Their parents are likely to be heavy users and believe there is nothing wrong with raising them in such a way.

Some experts contest there is still insufficient evidence to prove screens are harmful to child development. Be that as it may, it is better to err on the side of caution. As the WHO rightly pointed out, prolonged use of such devices results in a sedentary lifestyle and insufficient exercise, which may lead to obesity and other health problems. Children less than a year old should spend at least half an hour each day on their stomachs, and those that are older should get at least three hours of physical activity daily.

Given that digital devices have become an integral part of modern living, it is impossible for children to steer clear of such gadgets and, when used properly, they may be beneficial to learning and communication. The WHO guidelines point the way forward. Adults need to spend less time on their screens and set a good example if they want their children to do the same. Moderation is the key.
