  • 2

    Increased daytime light exposure and reduced nocturnal light exposure are associated with a lower risk of MASLD and its progression.

  • 3

    Each additional hour of daylight exposure above 6000 lux correlates with a 9% lower risk of MASLD.

  • 4

    A favorable 24-hour rest-activity rhythm profile is linked to improved life expectancy in individuals with MASLD.
