Sleep is a vital component of athletic performance, recovery, and overall health. Variability in sleep quality among athletes is influenced by factors such as chronotype (individual differences in circadian rhythm), training schedules, competition levels, and sex. The study, “Chronotype, Sleep Hygiene, and Sleep Characteristics Among Athletes of Different Disciplines,” investigates these variables to identify differences in sleep patterns and hygiene across sport types (team vs. individual), competition levels (elite vs. non-elite), and sexes, while also exploring correlations among chronotype, sleep hygiene, and sleep quality
