Study Notes
Screen Time and Its Effects
- The average daily screen time is over 5 hours, not including text messages or listening to music, which is a quarter of the day.
- Screen time can be broadly categorized into two buckets: one that blames smartphones, video games, and social media for increases in depression, anxiety, and obesity, and another that suggests screen use can improve self-esteem by keeping people connected.
Limitations of Screen Time Research
- The term "screen time" is not useful because it doesn't specify what activity is being done on the screen.
- Context matters, as spending time creating a video is different from watching cat videos.
- Researchers need to break down variables such as specific screen activity, passive or active engagement, and duration to understand the effects of screen time.
Physical and Mental Health Impacts
- Screen time can take a physical toll, including bad sleep, concentration difficulties, and irritability.
- Multiple studies have shown that using phones before bed leads to bad sleep.
- In 1991, 26% of teens got less than 7 hours of sleep, compared to over 40% today.
- Teens who spent 5 hours online were 50% more likely to not sleep enough compared to those who spent only 1 hour online.
Addiction and Feedback Loops
- Researchers use the term "addiction" to describe how people interact with devices, including video games and social media.
- Interacting with devices can create short-term dopamine-driven feedback loops, leading to constant craving for the next pleasure boost.
- There is debate on whether this is a bonafide addiction like gambling.
Depression and Suicidal Thoughts
- A 2017 study found that the more time people spent in front of screens, the more it affected their wellbeing, increasing their chances of developing depression and suicidal thoughts.
