A new study, co-authored by Dr. Kushlev, revealed that reducing—not eliminating—mobile internet use can significantly improve mental health, attention, and overall well-being. Researchers conducted a two-week trial where participants blocked internet access on their smartphones while still being able to call and text. Results showed that 91% of participants experienced positive changes, such as better focus and increased engagement in offline activities like exercise and in-person socializing.
However, many participants struggled to fully comply with the restriction, highlighting that complete disconnection may not be necessary. Instead, the study suggests setting boundaries—like limiting mindless scrolling and disabling notifications—can yield meaningful benefits. Rather than a full digital detox, small changes in phone habits may be the key to a healthier, more balanced life.

This week we are welcoming two new research assistants to our lab: Kace Boland and Zara Niazi! Both Kace and Zara will assist with onboarding sessions for our NIMH-funded study assessing the effect of initial exposure to social media on adolescent mental health.

Happy Tech Lab researchers Dexter King, Kibum Moon, and Kostadin Kushlev recently tested the impact and effectiveness of time-specific digital detox interventions among college students, intending to reduce digital device use before and after sleep…
“Results indicated that participants found it difficult to comply even with such brief digital detox practices, and that there was no difference in daily affect between those who were assigned an intervention compared to the control group. However, when students successfully practiced digital detox before bed, they used their phones less and felt better the following day compared to control participants, and practicing digital detox in the morning more often was associated with better daily affect. Future research should examine how to help people practice digital detox more effectively, with a particular focus on curbing phone use at critical times of day, such as before and after sleep.”
