Sleep disturbances significantly correlate with weight gain. Poor sleep quality can disrupt the hormones that regulate hunger, increasing cravings for high-calorie foods. Furthermore, insufficient sleep can lead to decreased energy levels, making individuals less likely to engage in physical activity. Chronic sleep deprivation is often linked to higher levels of cortisol, a stress hormone associated with fat accumulation, especially in the abdominal area. Addressing sleep issues is essential for effective weight management, as improved rest can regulate appetite and enhance metabolic function.
