A new study has found that sitting or lying down for more than 30 minutes at a time may increase the risk of dying from cancer.

Researchers discovered that prolonged, uninterrupted sitting is linked with higher cancer mortality rates.

Each additional hour of continuous inactivity was associated with around a 10% rise in risk.

However, breaking up sitting time with light activities like walking or household work significantly reduced the danger.

Even short bursts of movement each day were shown to improve health outcomes and lower risk levels.

Experts say regular movement breaks, even during office hours, are essential for better long-term health.
