A doctor has warned about the harmful effects of excessive screen time on phones, linking it to various health issues such as obesity, anxiety, and brain damage. According to Wales Online, screen time has been associated with a range of problems including joint and muscle pain, weight gain, cognitive decline, anxiety, eye strain, and insomnia. The average screen time in the UK is reported to be over five hours per day, with a significant number of people expressing concerns about spending too much time on their smartphones.
Dr Catherine Carney, a psychiatrist and addiction expert, highlighted the concept of “digital sugar” where individuals become increasingly reliant on technology, leading to similar physiological responses seen in substance addiction. She explained that the constant stimulation from social media can create a dopamine-driven cycle, impacting mental health and behaviour. Dr Carney emphasised the importance of recognising the signs of tech addiction and taking steps to address the issue.
One of the major concerns raised by health professionals is the impact of high screen time on cognitive function. Research funded by the National Institutes of Health has shown that children who spend long hours on screens may experience premature thinning of the brain cortex, affecting their learning abilities. Dr Carney pointed out that excessive screen use can also lead to posture-related problems such as “text neck,” where the head leans forward, causing strain on the neck muscles and spine.
In addition to cognitive and physical health issues, excessive screen time can also contribute to a sedentary lifestyle, increasing the risk of weight gain, obesity, diabetes, and heart disease. Dr Crystal Wyllie from ZAVA Online Doctor highlighted the negative effects of prolonged screen use on eye health, leading to eye strain, headaches, and poor posture. She emphasised the importance of taking breaks and setting limits to reduce the strain on the eyes.
Moreover, the psychological impact of heavy social media use was discussed, with Dr Carney noting that platforms like social media can exacerbate feelings of inadequacy and anxiety. The quest for likes and validation can create a cycle of seeking approval, affecting self-esteem and mental wellbeing. Dr Carney also raised concerns about the potential decline in social skills as individuals become more dependent on virtual interactions, leading to a disconnect from real-world relationships.
The disruption of sleep patterns due to late-night screen use was highlighted as a common issue, affecting melatonin production and subsequently impacting overall sleep quality. Dr Wyllie noted that poor sleep can lead to cravings for unhealthy foods and decreased concentration levels during the day. To address these issues, experts recommended strategies such as implementing screen-free zones, setting time limits, and adhering to the 20-20-20 rule, which involves taking breaks every 20 minutes to rest the eyes.
In conclusion, the growing reliance on digital devices has raised concerns among health professionals about the long-term impact of excessive screen time on physical and mental well-being. It is important for individuals to be mindful of their screen use habits, recognise the signs of addiction, and take proactive steps to mitigate the negative effects. By implementing strategies to manage screen time and prioritise real-world interactions, individuals can safeguard their health and well-being in an increasingly digital age.
