Sleep plays a crucial role in weight and metabolic health. Insufficient sleep disrupts hunger hormones, increases cravings, and lowers metabolism, promoting fat storage. Prioritizing quality sleep supports appetite control and complements diet and exercise for better health.

A chronic lack of sleep is becoming a global problem, with many recent studies suggesting that our increased use of technology is partly to blame. Screen devices such as smartphones and tablets can affect our shut-eye by emitting blue spectrum light, which suppresses the melatonin production we need to sleep.
