ABSTRACT: While there was a necessary initial focus on physical health consequences of the COVID-19 pandemic, it is becoming increasingly clear that many have experienced significant social and mental health repercussions as well. It is important to understand the effects of the pandemic on well-being, both as the world continues to recover from the lasting impact of COVID-19 and in the eventual case of future pandemics. On March 20, 2020, we launched an online daily survey study tracking participants’ sleep and mental well-being. Repeated reports of sleep and mental health metrics are being collected from participants ages 18–90 throughout the pandemic (March 20 – present). Given both the comprehensive nature and early start of this assessment, open access to this dataset will allow researchers to answer a range of questions regarding the psychiatric impact of the COVID-19 pandemic and the fallout left in its wake. Data collection is ongoing and regular updates with additional data will be made when possible Link to Data Descriptor Paper: [HERE][1] ****PLEASE SEE RELEVANT README FILES BELOW TO LEARN MORE ABOUT THE VARIABLES COLLECTED AND DATA AVAILABLE FOR USE**** [1]: https://www.nature.com/articles/s41597-021-00886-y.epdf?sharing_token=hL1Up0AF-2s6i8wFyPQZc9RgN0jAjWel9jnR3ZoTv0MfemC_yDXXjuv4C4a6hn17rqPfFOkst3mTFJFri1_23bnEfWEaEw2yt4Z7YYVOCSW30BWtpVc-Miujs2w_UmjU2BEs_tFFERlUM55DHQpZqIki6WEExB2jkKGO1KoOvJ8=
