Late-night lifestyle may be quietly damaging your liver

In fast-paced cities, staying awake well past midnight has become the new normal. Office deadlines stretch into the night, global work schedules demand odd hours, and binge-watching a favourite web series often feels impossible to stop after just one episode. Add a packet of chips, sugary snacks, caffeine, or even a late-night drink, and what seems like an ordinary evening may actually be placing extra stress on your liver.
According to Dr Shruthi H.S. Reddy, Consultant – HPB & Liver and Pancreatic Transplant Surgery and Robotic Surgery at Manipal Hospital, Old Airport Road, these modern lifestyle habits are quietly affecting liver health. While many people focus on diet and exercise, they often overlook one major factor—sleep. Experts say the relationship between sleep and liver health is closely connected, with poor sleep affecting liver function and liver problems, in turn, disturbing sleep quality.
The human body follows a natural 24-hour cycle known as the circadian rhythm, which regulates sleep, digestion, hormone production and metabolism. When people stay awake late regularly, this internal clock becomes disrupted.
This disruption can affect the body’s ability to process food efficiently and regulate blood sugar and fat metabolism. Over time, it may increase the risk of Metabolically Associated Steatotic Liver Disease (MASLD), commonly known as fatty liver disease. Studies suggest that poor sleep quality plays a significant role in this condition.
Many people believe they can make up for lost sleep by sleeping the next morning. However, experts say daytime naps do not completely reverse the effects of repeated sleep deprivation. Weekend catch-up sleep may help partially reset the body’s clock, but it should not become a substitute for consistent, good-quality sleep. Doctors recommend getting around seven to eight hours of quality sleep every night. Regular exercise and spending time in natural sunlight can also help restore the body’s internal rhythm.
Sleep is only part of the problem. What people eat during late-night hours also matters.
Stress, long work shifts and entertainment often encourage people to reach for calorie-rich snacks, fast food, sugary treats or caffeinated drinks. These foods are typically high in fat and sugar, making them harder to digest when the body is preparing for rest.
Poor sleep can also increase cravings for unhealthy foods, creating a cycle where lack of sleep leads to overeating, and unhealthy eating further affects sleep quality. Over time, this combination can contribute to fatty liver disease, which may progress to liver inflammation, scarring and even cirrhosis if left unmanaged. Source: India Today
