Are you one of the many typical zombie-fied cellphone-addicted people, connected in the modern digital world of emails, social media and the internet?
Nowadays, it’s difficult to pinpoint something that can’t be found, bought or watched online, directly from our smartphone or tablet in the palm of our hands. With a whole list of possibilities at our fingertips, it’s not surprising that many of us develop a dependency on ourlittle pocket-rockets. Each day, people spend hours looking down at their hand-held device, whether it be for work, education, social or just to fill the time.
What many people fail to realise is that frequent overuse of such technology, in conjunction with poor ergonomics, can be responsible for a number of health issues. The consequences are usually musculoskeletal based (joints, muscles, nerves, ligaments etc), but has also less commonly been linked to cases of ill-health and sickness. Make yourself aware of the risks associ
ated with using a smartphone or tablet to reduce the impact it can have on your body.
Hold or position the device at eye level
As your head tilts forwards to look down at your phone or tablet, you are putting a great deal of force on your cervical spine (neck). This delicate structure houses your spinal cord, which sends messages from the brain to all areas of your body. When you hold the device directly in front of you, your head will retain its healthy and neutral position, and therefore minimises the strain on your neck. If you can’t do anything about the positioning, move your eyes to look down and not your neck.
Alternate between thumb and fingers to type
Constantly using your thumbs to type, particularly on smartphones, can lead to undesirable repetitive strain injury otherwise known as De Quervain syndrome. The repeated action of pressing buttons, virtual or on a keypad, will cause a gradual onset of pain in the thumbs and wrists. To avoid this, alternate between using your thumbs and fingers to type – it may feel unnatural at first, but it doesn’t take too long to master. Tip: Turn your device on its side to reveal a larger keyboard, making it easier to type with your fingers.
Keep wrists as relaxed as possible
Ensure your wrists are straight and relaxed using a comfortable neutral grip of the device. If they are bent or twisted, not only will it cause strain in the wrists but your fingers and thumbs will have to work a lot harder when pressing the screen / buttons.
Adjust the device settings
Smartphones and tablets are usually equipped with a number of adjustable settings ideal for ergonomics. Reduce the brightness on the device when you are in a dimly lit or dark environment to reduce the common issue of headaches and eyestrain. You are also able to adjust the size of displayed text, meaning those with poor eyesight won’t have to struggle to read smaller lettering.
Other adaptable features to reduce eye strain include the option of bold text, magnifier camera tool, contrast tuning and zoom.
Use the devices’ digital assistants
Many smart devices can now respond to the sound of your voice. The inbuilt digital assistants (more familiarly known as Siri, Alexa, Cortana or Google) can carry out various handy actions by voice instructions, including composing and sending texts, ringing contacts,adding reminders to your calendar and searching the internet. Using these features will mean you can control your device without even having to touch it, eliminating all risks of related injury.

Use supported accessories
You can purchase low cost supporting accessories for all of your devices, including things like a folding case tablet stand for the table, an easy-grip case, or a portable ergonomic keyboard. Earphones with inbuilt microphones, hands-free sets and auxiliary cords are useful for avoiding awkward positions, especially for those who engage in frequent phone calls as part of their job.
Take frequent breaks
Allowing yourself to take frequent breaks when using any illuminated device is crucial for giving your eyes a rest. Staring for long periods of time at the illuminated screen can cause eye strain and headaches, as well as more serious problems like Computer Vision Syndrome (CVS).
Stretching the individual parts of your body that are involved in your device use (such as your fingers, wrists and forearm) will help you stay loose and avoid pain occurring.There are apps available for download to help you with stretching exercises and ergonomics tips. Healthyworking+ is a free ergonomics management app offering videos & guides with the aim to prevent the development of musculoskeletal disorders in regular phone, tablet and computer users.
Decrease the amount of time spent on devices
The use of your phone or tablet may be unavoidable in work, school or social situations; nevertheless, you should try and reduce the amount of time you spend on your devices whenever possible. Many of us have made checking the timeline a standard part of our routine, with regular scrolling from the moment we wake up until we fall asleep. Use libraries instead of the internet, meet up with friends instead of video calling them, or go and experience the great outdoors instead of lying around on social media.
