A study by China-based researchers has found that a specific number of hours and minutes per night can best control insulin resistance. The study, which used data from over 10,000 participants, found that less than the optimal seven hours and 19 minutes a night was associated with a higher eGDR, or less risk of diabetes, particularly for women and those aged between 40 and 59. The researchers also found that "weekend catch-up sleep," or sleeping in on the weekend to make up for a weekday sleep deficit, was beneficial in moderation for those with sleep debt but potentially harmful for others. The results also highlighted the importance of personalized sleep recommendations for patients with metabolic concerns.
