A recent study conducted by the University of Manchester has identified a simple and cost-free habit that can improve cognitive functioning: regular exposure to natural light. In a week-long study involving 58 adults, it was found that those who spent more time in natural daylight performed 7% to 10% faster on reaction tests, demonstrating heightened attention and reduced mental fatigue compared to those who had less exposure.

The investigation highlights the benefits of natural light, suggesting that simple actions like opening curtains, working near a window, or stepping outside for a few minutes can profoundly impact mental alertness and information processing. Unlike traditional forms of cognitive enhancement like caffeine or nutritional supplements, which many people rely on, this habit is accessible to everyone and does not come with any financial costs.

The findings point to a growing recognition of the importance of our environments on mental health and performance. By harnessing the power of natural light, individuals can foster better focus and cognitive processing, suggesting a need for greater awareness and adaptation of daily routines to incorporate these beneficial practices.
