• The use of circadian-informed lighting, where artificial lighting is synchronised to the natural biological rhythms or a person’s ‘body-clock’, significantly improves quality of sleep and work performance for night shift workers, a major new trial has found. https://academic.oup.com/sleep/advance-article/doi/10.1093/sleep/zsae173/7724228?login=false 9 comments 26/9/2024 science
• Research found drinking even a small amount of alcohol before bed can adversely affect sleep quality. People who do not get enough REM sleep can experience emotional problems, mental acuity difficulties and memory issues. https://academic.oup.com/sleep/advance-article-abstract/doi/10.1093/sleep/zsae003/7515846?login=false&redirectedFrom=fulltext 90 comments 28/1/2024 science

• Study using light-detecting wearables finds that irregular lighting patterns are associated with irregular sleeping patterns. Adolescents with the most consistent lighting patterns had longer and earlier sleep times. https://academic.oup.com/sleep/advance-article/doi/10.1093/sleep/zsad001/6982548 5 comments 29/5/2023 science
