A surprising finding from researchers at the University of Leicester: spending over two hours driving each day may impair cognitive function similarly to excessive TV watching. In a study involving 500,000 adults aged 37 to 73, driving emerged as the daily activity most detrimental to IQ, our key measure of intelligence.
Prior research has shown long drives (over three hours) harm cardiovascular health due to stress. Now, evidence points to impacts on brain function. The brain becomes idle during extended driving, much like passive TV viewing, because it receives minimal stimulation. Notably, this isn't tied to physical inactivity—activities like video gaming or computer use keep the mind engaged. Instead, driving-induced stress and fatigue contribute to cognitive downtime.
Opt for public transport next time: it's a chance to read, observe, and stimulate your mind.
