Sleep quality significantly impacts hormone levels, particularly those that regulate appetite and stress. Poor sleep can disrupt hormones like ghrelin and leptin, which control hunger, often leading to increased cravings and overeating. Additionally, sleep deprivation raises cortisol levels, the stress hormone, which can impact metabolism and overall health. Regular, restorative sleep helps maintain hormonal balance, supporting weight management and mental wellbeing. Prioritizing quality sleep is crucial for optimizing physiological functions and enhancing fitness performance.
