The Dark Side of Screens: Exploring the potential cancer risks

Screens dominate our lives today. A common habit is using phones, tablets, computers, TVs. As a result, some are concerned because they wonder what screens are doing to our well-being, particularly in relation to cancer. So, does screen time increase the risk of developing cancer?

Academics have researched whether there is a connection with screen time and cancer. One major concern is blue light, the type of light emitted by screens. This light diminishes melatonin, a hormone that contributes to good sleep. Lack of sleep has been associated with an increased risk of some cancers, including breast, colon and prostate cancer.
What does the Studies Show?
Some research suggests a correlation between screen time and cancer, but there’s no evidence right now. That’s partly because the studies don’t always measure screen time in the same way.


While we don’t fully understand the relationship between screen time and cancer, there are steps we can take to safeguard our health. Here are some practical tips:
Use the 20-20-20 rule: Every 20 minutes, pause, hold for some time and focus on something 20 feet away for 20 seconds.
Wear glasses or apps that delete blue light from screens.
Avoid screens before bedtime; read or choose to read or relax instead.
Maintain a routine sleeping schedule to ensure you sleep well.

In summary, although there is some evidence to suggest a potential connection between screen use and cancer risk, further extensive research is required. Putting these handy tips into action can actually help with healthier living overall. Paying attention to how much time we are spending on screens and restricting blue light exposure can help us have healthier habits and perhaps lower our risk of cancer
