A study on Wednesday proved a suspected link between poor sleep and metabolic dysfunction-associated steatotic liver disease (MASLD). 

MASLD (formerly known as non-alcoholic fatty liver disease) is the most common liver disorder: it affects 30 per cent of adults and between 7 per cent and 14 per cent of children and adolescents. This prevalence is predicted to rise to more than 55 per cent of adults by 2040.
