New study finds reducing sleep by just 80 minutes per night harms your health: Neurologist Dr Sudhir Kumar explains

A study published today links reducing nightly sleep by as little as 80 minutes to adverse health effects, including weight gain. Researchers at Columbia University Irving Medical Center highlight disrupted sleep patterns—such as those caused by late-night events like the FIFA World Cup—as a contributing factor. The findings align with broader warnings from neurologists, including Dr.

Sudhir Kumar, who emphasize sleep’s role in metabolic health despite other healthy habits like diet and exercise. Coverage from *The Economic Times*, *Firstpost*, and *Hindustan Times* frames the study as a wake-up call for adults prioritizing work or entertainment over sleep. *The New York Post* and *Columbia University Irving Medical Center* focus on the metabolic consequences, noting even minor sleep reductions may alter hunger hormones and increase fat storage. No specific mechanisms or long-term health risks are detailed beyond weight gain.

Watch for follow-up studies on sleep duration thresholds and public health guidelines. Media may amplify the findings during major sporting events or late-night cultural moments, where sleep disruption is common. Clinical trials on sleep interventions could emerge as a response.
