芬兰研究显示每晚睡7至9小时者减重最成功

Core Insights - A recent study in Finland indicates a strong correlation between sleep quality and weight management, highlighting that sleep duration, circadian rhythm, and daytime alertness significantly impact weight loss outcomes [1] Group 1: Study Findings - The research involved over 1,800 adult participants in a digital lifestyle intervention program, tracking weight changes alongside sleep duration, circadian rhythm, daytime alertness, and sleep apnea occurrences [1] - Participants who slept 7 to 9 hours per night achieved the best weight loss results, while those sleeping less than 7 hours experienced poorer outcomes [1] - Individuals with early sleep and wake times showed better weight loss results compared to those who stayed up late and woke up late [1] Group 2: Additional Observations - The presence of sleep apnea was associated with smaller weight loss, indicating its negative impact on weight management [1] - Higher daytime energy levels and alertness were linked to more significant weight loss, suggesting the importance of overall well-being in weight management [1] - The study also concluded that digital lifestyle interventions can effectively support weight management efforts [1]
