As societies become more urbanized and densely populated, understanding how our environmental surroundings shape human cognition is increasingly critical. Growing evidence suggests that urban noise pollution can hinder learning, whereas spending time in peaceful green spaces can alleviate mental fatigue and restore attentional capacity. This study investigates how these different environments affect the brain and impact an important aspect of memory that depends critically on mental downtime. Brief periods of wakeful rest provide opportunistic windows for memory consolidation, an automatic process that engages whenever the mind is free from goal-directed task demands. It is during these moments of rest that recently learned experiences are unconsciously replayed and stabilized into durable memory traces. To evaluate how nature versus urban environments affect this crucial consolidation window, we designed an experiment where participants first listen to a narrative story to establish an initial learning experience. Shortly after learning, participants either experience a period of wakeful rest in a peaceful botanical garden setting or in a noisy urban setting, or else complete an active control task. During these sessions, we use portable electroencephalography (EEG) to record brain activity and physiological monitoring to measure arousal levels. This allows us to track how different surroundings modulate the brain’s automatic offline processing, helping us determine how distinct environmental experiences influence later memory recall. By examining whether noise-limited natural contexts are more likely to promote brain processes conducive to wakeful consolidation than urban environments, this research aims to uncover the mechanisms linking environmental factors to memory while highlighting the potential benefits of equitable green spaces in our communities.
