The Influence of Technology on Physical Exercise

Written by Kaitlyn. A | Accredited Exercise Physiologist 

How has technology progressed over the last 5 years?

Since the COVID-19 pandemic there has been a dramatic increase in technology being used across all age groups (Hassinger-Das et al., 2020). In 2017 a study was conducted that showed children under eight years spent more than two hours per day participating in various screen time such as TV, mobile phones, smart toys and devices. Which has only increased with the pandemic shifting from in person schooling to virtual via a computer (Hassinger-Das et al., 2020). Over the years technology use has increased as the world has involved using smartphones, tablets, ipas and computers all associated with increased periods of sitting (Jones et al., 2021). In 2021, Jones et al found that 45-80% of children and adolescents are not meeting the screen time recommendations. For an individual to reduce screen time, behaviour change strategies have shown to be effective. Examples of this include: goal setting, reviewing goals, social support and self monitoring have shown the most benefinacal (Jones et al., 2021).

What impact does screen time have on our health?

Exposure to screens from a young age has been associated with increased risk of developing health conditions as a result (ROGOVIĆ1, ŠALAJ and PUHARIĆ3, 2022). The use of technology has led to conditions such as developmental delays, attention issues, sleep disturbances, poor food choices leading to increased cardiovascular risks, high blood pressure, insulin resistance, increased weight, higher levels of depression and poor posture (Rohanachandra, 2022; Hassinger-Das et al., 2020). The ability to focus at school or work can also be impacted with increased fatigue, eye discomfort and blurry vision (Rohanachandra, 2022). This impact transitions into the quality of sleep and irregular sleep patterns affecting everyday life. A study showed that one hour of screen time was associated with 16 mins of sleep lost in children (Rohanachandra, 2022) demonstrating the association with screen time negatively impacting sleep quality. Therefore the use of technology has a negative impact on overall health and trying to reduce the use of screen time where possible is recommended to improve all aspects of wellbeing (Jones et al., 2021).
