Overreliance on GPS May Dull Spatial Memory, Experts Advise Navigational Exercise
Studies show habitual GPS use can weaken the brain's navigation center, prompting experts to recommend occasional map-free travel and traditional wayfinding techniques.
A 2020 McGill study of fifty participants linked regular GPS reliance to diminished spatial memory and shrinking of the hippocampus, the brain area also tied to episodic recall and stress regulation. Neuroscientist Louisa Dahmani cautions that prolonged neglect of this region may raise long-term dementia risk. To counteract the effect, travel author Tara McAndrew deliberately navigates without digital assistance after reaching her destination, blending modern apps with personal orientation.
Indigenous knowledge keeper Brenda Holder teaches using environmental landmarks such as sun position and river flow, warning against overdependence on technology. Meanwhile, disruptions to satellite navigation in conflict zones have spurred a resurgence of legacy systems like ground-based LORAN and renewed teaching of celestial navigation in naval academies.
Why it matters
Understanding GPS's impact on brain health encourages habits that preserve navigation skills and may reduce dementia risk.
