According to Healio, losing 5% or more of your body weight is linked to improved sleep quality and duration.
Sleep quality and duration were evaluated using the Pittsburgh Sleep Quality Index questionnaire, and mood by the Patient Health Questionnaire-8. Both were assessed at baseline and at months 6 and 24. Sleep and mood changes were evaluated by treatment group and based on participants who lost at least 5% of initial weight vs. those who lost less.
