Blue Light Not Main Sleep Disruptor, Says Czech Sleep Researcher

Blue light from electronic devices is not the primary threat to quality sleep that many people believe, according to diabetologist Michal Dubský from Prague's IKEM institute, who also conducts sleep research. Dubský recommends maintaining consistent sleep and wake times every day, including weekends, for optimal body function. He also advises avoiding food for three to four hours before bedtime to improve sleep quality. The researcher's findings challenge common assumptions about digital device usage and its impact on sleep patterns.
