Stay Energized During Long Fasts: Top Hydration Tips to Beat Fatigue, Headaches, and Dizziness

Hydration Tips to Beat Fatigue, Headaches, and Dizziness During Long Fasts.

Fasting—whether for health, religious, or cultural reasons—can strain the body’s fluid balance, often causing fatigue, dizziness, and headaches. Dr. Ajay Shah, Chief of Lab at Neuberg Ajay Shah Laboratory, shares strategies to stay hydrated and safe.

Pre-Fast Hydration: Drink plenty of fluids before fasting and eat water-rich foods like cucumbers, melons, and soups. Coconut water or water with a pinch of rock salt helps maintain electrolytes. Avoid caffeinated and sugary drinks during the fast.

Monitor Your Body:

Electrolytes: Track sodium and potassium to prevent cramps and weakness.

Blood Pressure: Watch for sudden drops when standing.

Kidney Health: Monitor creatinine, BUN, and urine concentration.

People with hypertension, diabetes, or kidney issues should consult a doctor before prolonged fasting. Combining smart hydration with monitoring helps prevent dehydration, sustain energy, and safeguard long-term health.
