    Sleep plays a critical role in regulating energy levels and preventing lethargy. Adequate sleep supports brain function, hormone balance, and cellular repair, helping individuals feel alert and productive. Insufficient or poor-quality sleep disrupts circadian rhythms, leading to fatigue, reduced concentration, and weakened immunity. Chronic sleep deprivation may also affect metabolism, increasing feelings of sluggishness. Healthcare discussions, including topics like cephalexin capsules wholesale, sometimes highlight how proper rest supports recovery and medication effectiveness. Establishing consistent sleep schedules, limiting screen exposure, and maintaining a relaxing bedtime routine significantly improves overall vitality and reduces daytime lethargy for long-term health benefits and wellness outcomes.
