We live a very digitized life, where every day it becomes more challenging to put the phone down. Not only are most people working in front of a screen all day, but most do it at home too. Several people go home after work and sit in front of the TV and browse their phones until the day ends. Last time, we spoke about the history and current state of our digital lives, and how things got to be this way. Today, I’ll go into the impact our tech-focused world has on your health.
A group of studies is starting to demonstrate the impact of technology on our bodies. It is safe to say that we are very limited in the knowledge and research about the long-term effects of technology. As people age with social media and wireless technology, we will likely have more discoveries that change our relationship with the digital world. For now, here are a few known issues.
Unsurprisingly, obesity, and screen time are connected. A large study of over 90,000 participants concluded that independent of physical activity, it was observed that obesity and screen time are positively correlated. A longitudinal study showed that 60% of overweight incidence in their study was attributable to excess television viewing.
Another impact on our physical health is our vision. A growing body of research indicates that around 50% of the population will experience Digital Eye Strain (DES). DES is a syndrome that causes a person to have various symptoms like sore, dried, tired, burning or itching eyes, headaches, sore neck, or even a difficulty keeping your eyes open. It can undoubtedly be treated, but no studies demonstrate the long-term impact on our vision.
Screen time can also impact your posture. A study by Harvard, Brigham and Women’s Hospital, and Microsoft show that spending too much time on small devices like a phone can strain muscles, nerves, tendons, ligaments, and spinal discs.
Finally, one of the most prevalent physical health impacts of too much screen time is the lack of quality sleep. Research has now demonstrated that the screen light (called blue light) of our device can stimulate the cells in our eyes and reset our internal clock, which is the circadian rhythm. Not only does this affect our sleep, but it could also cause some health issues since circadian rhythm issues are connected to cancer, metabolism issues, and cognitive dysfunctions. Since sleep is a big challenge for many people, next time will provide you with tips on how you can improve your bedtime routine and get more sleep every night.
