Biological rhythms and reading habits influence sleep and cognitive performance

Research suggests that reading before bed can significantly improve sleep quality by providing a calming mental rhythm that replaces the stimulating blue light emitted by digital screens. Unlike smartphones, which disrupt melatonin production, books help reduce mental noise and anxiety by distracting the brain from daily stressors. Establishing a consistent reading routine serves as a psychological signal to the body that it is time to rest.

Additionally, cognitive performance is heavily influenced by individual biological rhythms rather than a universal peak time. While attention, memory, and learning abilities fluctuate, neuroscientists note that an individual's internal clock determines when their brain processes information most effectively. Morning types perform best during early hours, while evening types show peak neurological connectivity and alertness much later in the day. Success in cognitive tasks depends on aligning activities with these personal biological rhythms.
