Hydration is the proper intake of fluids to support vital body functions such as temperature regulation, nutrient transport, detoxification, digestion, and cognitive activity. Water is the main component of the human body, accounting for about 60% of the body weight of an adult.
Importance in the post:
During intermittent fasting or black fasting, hydration is essentialto prevent symptoms such as headaches, dizziness, constipation and decreased mental or physical performance. Since fasting reduces food intake, much of the water that normally comes from food is missing, so water consumption should be increased.
Plain water, mineral water (for natural electrolytes), unsweetened herbal infusions and occasionally water with a powder of quality salt (pink Himalayan salt, sea salt) are recommended.
Signs of improper hydration:
- Dark urine
- Sharp fatigue
- Dry mouth
- Muscle cramps
- Dizziness or difficulty concentrating
Recommended sources of hydration in fasting:
- Plain water (filtered or spring)
- Mineral water with natural magnesium and sodium content
- Herbal teas (mint, ginger, yarrow, etc.)
- Natural electrolytes — non-iodized salt + water + lemon juice (optional)
