Getting enough good-quality sleep is often overlooked in weight management discussions, but as a GP, I've seen how it can make or break someone's efforts. In Australia, where around two-thirds of adults are overweight or obese, poor sleep can disrupt hormones, increase cravings, and reduce energy for healthy habits. This article explores the impacts of sleep on weight, touching on key angles like sleep apnoea, shift work, mental health, and environmental factors such as screen time. Drawing from reliable evidence, we'll look at how these issues interplay and offer practical tips to improve sleep for better health.
