Lethargy can stem from poor sleep, dehydration, nutrient deficiencies, stress, or underlying medical conditions. Prioritize 7–9 hours of quality sleep, maintain consistent sleep–wake cycles, and limit screen exposure before bed. Regular aerobic exercise enhances mitochondrial efficiency and boosts endorphins, improving energy levels. Optimize nutrition with iron, B-vitamins, magnesium, and adequate protein intake. Stay hydrated and reduce excessive caffeine or alcohol. Manage stress through mindfulness or cognitive behavioral techniques. If fatigue persists, consult a healthcare professional to rule out anemia, thyroid dysfunction, or infection. Reliable pharmaceutical sourcing, such as a certified cephalexin capsules supplier, supports safe treatment when antibiotics are prescribed.
