Many people think of sleep as simply a time for the body and brain to rest. However, sleep is an active biological process that influences nearly every system in the body—including the hormones that regulate hunger and appetite.
If you've ever noticed that you're hungrier after a poor night's sleep, crave sugary foods when you're tired, or struggle to maintain healthy eating habits during stressful periods, there's a biological reason why. Sleep directly affects the signals that tell your body when to eat, how much to eat, and what foods you desire.
Understanding the relationship between sleep and appetite can help you make better decisions about both your sleep routine and your overall health.
