Sleep Hygiene

Sleep hygiene refers to healthy habits and environmental practices that promote consistent, restorative sleep and support weight management.

Sleep hygiene is about creating the right habits and environment for good-quality sleep — like keeping a regular bedtime, avoiding screens before bed, and making your bedroom cool and dark. Poor sleep can make you hungrier, crave unhealthy foods, and feel too tired to exercise. Getting 7 to 9 hours of quality sleep each night is an important but often overlooked part of managing your weight.

Sleep hygiene encompasses a set of behavioural and environmental recommendations designed to promote healthy sleep duration and quality. Insufficient sleep — defined as less than 7 hours per night in adults — is associated with dysregulation of ghrelin and leptin, increased cortisol levels, impaired glucose tolerance, and reduced resting metabolic rate, all of which contribute to weight gain and difficulty losing weight.

Sleep is often the missing piece in weight management. At NuLifeCare Singapore, Dr. Joseph Wang evaluates sleep patterns as part of a comprehensive weight assessment, because addressing poor sleep can significantly improve the results of diet and exercise interventions.
