A study found that deactivating Facebook and Instagram for six weeks before the 2020 US election led to a small but significant improvement in users' emotional state, with a 0.060 standard deviation improvement in happiness, depression, and anxiety for Facebook and 0.041 for Instagram. The study suggests that the effect of Facebook deactivation is driven by people over 35, while the Instagram effect is driven by women under 25. The study's findings are based on two large randomized experiments. The results have implications for understanding the impact of social media on mental health.
