A recent survey explored the impact of health tracking on Americans' sleep and mental health. The survey, which included 2,009 adults, examined the metrics people track and how often they do so. It found that more tracking does not always lead to less worry, and some individuals experience what is referred to as "optimization anxiety."

This anxiety appears to affect sleep the most. While some people use tracked data to build better habits, others become fixated on specific numbers.

Further details on the survey's findings are available, providing insight into the effects of health tracking on mental well-being and sleep.
