Your body’s internal clock, or circadian rhythm, influences everything from sleep to metabolism. Disrupting it—through late-night screen use, irregular sleep schedules, or poor lighting—can lead to fatigue, weight gain, and even chronic diseases. To optimize your circadian rhythm, aim for consistent sleep and wake times, get morning sunlight exposure, and limit blue light at night. Eating meals at regular times and avoiding late-night snacking can also improve metabolic health. Prioritizing your circadian health can enhance energy, focus, and overall well-being, making small lifestyle changes a powerful tool for long-term health
