Screen Time from Head to Toe 

By Caleb Hill and Randen Morisako 
In our high speed, high tech and highly global word, we may find ourselves doing more of what you are doing right this second – looking at screen. Like me, you are probably longing for the offline world to resume what is so important for developing children. An analog world of using your hands to create art with a paint brush, gain insight from a newly opened book or give a task-affirming high five just cannot be recreated through eLearning 
Teachers, parents and students alike need to manage this carefully in order to avoid overuse, stress and yes, injury.  
EYES 
If we aren’t mindful of screen time many of us are at risk to develop what ophthalmologists call “digital eyestrainFor children and adults this can lead to dry eye, eye strain, headaches, and blurry vision. While some symptoms may be temporary; they can persist if breaks are not taken. These symptoms do not mean special glasses are required or that an eye condition if forming; instead it could mean they aren’t taking enough breaks.   
Most doctors recommend what’s called the “20-20-20 rule” – Every 20 minutes, take a 20 second break and look at something that is 20 feet away (about 6 meters).

If you find you oyour child’s eyes are drying out quickly you may need to place a humidifier close to your eLearning space, use eye drops, and drink more water. The level of lighting in a room when using a computer or iPad should be roughly half as bright as other activities such as writing on paper. Decrease the brightness on your screens and try to position computers so that light from uncovered windows, lamps and overhead light fixtures aren’t shining directly on them.  
If you find dry eyes persist it could also be an issue as simple as not blinking enough. Blink!  
MIND-BODY CONNECTION 
Adults and children need to be moving. School has changed over the years and rarely at ISB will you find a group of students all sitting at desks for long periods at a time (exam time excluded). Students are missing that up and down interaction with their classmates and teachers and it adds a lot of extra pressure on parents. That’s why its so important to TAKE BREAKS. 
There are zero negative side effects to taking a physical activity break when you are working. It will help you work smarter and more efficiently after getting your heart rate up. As mentioned by Lissa in Strategies to Survive Working at Home its important to move your body. Students should take AT LEAST ten-minute break once every hour to rest their eyes and move their bodies. Set a timer to limit yourself and take breaks.

PE teachers are providing workout videos or activity suggestions multiple times a week and encouraging students to get at least 60 minutes of activity every day with 30 minutes of vigorous activity. This means that they are raising their HR and potentially getting hot and sweaty too.  
If you can safely do it, getting outside and taking a walk is more than enough to get your blood pumping. Get out for a morning walk before you start your eLearning, breathe some fresh air and look out the window to give your eyes a break. 
NECK AND SPINE 
Do you find yourself bending your head down to look at your screen? This is called “text neck.” For every 15 degrees of downward gaze your spine experiences an additional increase in stressYou can limit the risk of text neck by monitoring the amount of time, you spend staring down at your phone.   
Another strategy is to ensure that your laptop or computer monitor is set up at the right height. Your monitor should be set up so that the top of your monitor is perpendicular with your gaze. This ensures that you should be able to see the bottom of the screen with no more than 15-degree downward gaze.

WRISTS 
When using a keyboard and mouse we are at extended risk of carpal tunnel syndrome. This is an overdevelopment of the wrist/forearm muscles and causes irritation the nerves in the lower arm causing pain, numbness, and even tingling. Making sure that your hands and wrist are in the right position while working may prevent carpal tunnel syndrome. Periodically massaging or stretching your forearm muscles may also prevent muscle tightness in the forearm.

A simple forearm stretch is to straighten one arm out in front of you with your palm facing out and fingers pointed to the sky. Using your other hand, apply light backward pressure to the tips of your straightened hands finger. You can repeat this stretch with your fingers pointed down for a different muscle group. 
LOWER BACK 
Long bouts of sitting may cause back pain especially in the lower back. Be sure to sit properly with a straight spine. Using a lumbar support chair or small pillow on your lower back may support muscles there and keep your back from slouching.

During this time, one technique may be to try using a standing table. If you decide to do so make sure that the desk is high enough so that you don’t have to look down at your monitor and develop text neck. 
Sciatica is characterized by pain, numbness, or tingling that runs through the lower back, through the buttocks, and sometimes down the lower leg.  
By using a well cushioned chair and making sure that each buttock is evenly on your chair are some strategies to prevent sciatica. Other strategies include taking periodic breaks and including stretching or foam rolling of the glute muscles to make sure they do not get overdeveloped from prolonged sitting. 
Staying physically active during this time is extremely important. With a regular dose of physical activity, we can help limit the effects of prolonged sitting and screen time. Your eyes, brain and body will all thank you. Now… take a break!
