Excessive TV watching increases the risk of major depression, particularly for middle-aged adults. However, a study of 65,000 people found a simple solution: swapping just one hour of daily screen time for sports, sleep, or active commuting can lower depression risk by 11% overall. For those in middle age, the benefits are even greater, with a two-hour swap slashing risk by 43%. By making this small daily change, people can significantly protect their mental health and boost their overall well-being.
