A July 2022 study by the Guangdong Provincial Key Laboratory of Food, Nutrition and Health and Sun Yat-sen University in Guangzhou, China said, “People with poor nighttime sleep and prolonged daytime napping have the highest risk for developing fatty liver disease,” and “Our study found a moderate improvement in sleep quality was related to a 29% reduction in the risk for fatty liver disease.”
Poor “sleep hygiene” included
late bedtime
snoring
daytime napping for over 30 minutes
“Our study provides evidence that even a moderate improvement in sleep quality is sufficient to reduce the risk for fatty liver disease, especially in those with unhealthy lifestyles,”
“Given that large proportions of subjects suffering from poor sleep quality are underdiagnosed and undertreated, our study calls for more research into this field and strategies to improve sleep quality.”
