The good news is that there is no evidence that we or our families are doing ourselves any harm, as long as we take sensible steps.

• Sitting properly, with a 90-degree elbow angle and a plenty of back support is one key step we can take to protect our muscles and joints from strain.

• It’s also important to say around 60cm away from the screen so that our eyes don’t have to struggle to focus.

• Take breaks every now and then when you can stretch your legs and rest your eyes – the perfect excuse for a cup of tea.

• One of the most common computer-related problems is repetitive strain injury and carpal tunnel syndrome, which are painful conditions caused by small, rapid movements – typing or mouse-clicking – over a long period of time, so try clenching and unclenching your fists a few times to help ease the stress on your hands and wrists.

• Don’t forget to blink! Dry eyes are a major cause of eye strain.
