Summer Fatigue: Why You Feel Tired & Lethargic Even Without Exertion

• The body expends more energy on thermoregulation to maintain normal temperature in rising heat, leading to fatigue.
• Increased sweating in summer reduces body water levels; dehydration causes tiredness, lethargy, and headaches.
• Lack of sunlight decreases serotonin, affecting mood and causing sadness, sluggishness, and irritability.
• High humidity prevents sweat evaporation, hindering body cooling and causing a feeling of heaviness and fatigue.
• Maintain hydration, regular sleep, light meals, and avoid harsh sun to stay energetic.
