The literature on this topic is very recent, given the pandemic and the uncertainty of virtual and face-to-face work modalities. This study aimed to examine the effects of adults\u2019 prolonged exposure to screens on sleep quality, the type of devices used according to age and gender, periods of access to such devices and the impact on performance in the context of telework due to COVID-19. Specifically, the study analyzed the differences in the use of devices and in the time spent using them during and after teleworking between genders and age groups. A total of 127 Portuguese participants answered the Pittsburgh Sleep Quality Index and a questionnaire that we specifically developed to characterize teleworking habits. The results showed differences between men and women regarding the use of devices and its impact on sleep quality, as well as differences in terms of age. These results are discussed in terms of how the current work context may affect performance, sleep, gender differences and the adverse effects of exposure to screens during and after work hours.<\/jats:p>","DOI":"10.3390\/ijerph192114305","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T03:36:44Z","timestamp":1667360204000},"page":"14305","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Psychological Research on Sleep Problems and Adjustment of Working Hours during Teleworking in the COVID-19 Pandemic: An Exploratory Study"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5152-4467","authenticated-orcid":false,"given":"Sandra","family":"Figueiredo","sequence":"first","affiliation":[{"name":"Department of Psychology, Psychology Research Centre (CIP), Universidade Aut\u00f3noma de Lisboa, Foundation for Science and Technology (FCT), 1169-023 Lisbon, Portugal"}]},{"given":"Raquel","family":"Jo\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Psychology, Universidade Aut\u00f3noma de Lisboa, 1169-023 Lisbon, Portugal"}]},{"given":"Laura","family":"Alho","sequence":"additional","affiliation":[{"name":"Think Wise, 3810-133 Aveiro, Portugal"},{"name":"Mind\u2014Clinical and Forensic Institute, 1990-019 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8929-0945","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Hip\u00f3lito","sequence":"additional","affiliation":[{"name":"Department of Psychology, Psychology Research Centre (CIP), Universidade Aut\u00f3noma de Lisboa, 1169-023 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Beckel, J., and Fisher, G.
