Hydration and Your Cycle
Why water needs change throughout the month
Your Fluid Needs Aren't Static
Your body's fluid needs fluctuate throughout your menstrual cycle. Hormonal changes affect how your body retains and uses water.
During the follicular phase, estrogen increases blood volume. During ovulation, your body produces water-based cervical mucus. In the luteal phase, progesterone causes significant fluid retention. During menstruation, you're losing blood.
The same 8 glasses might be insufficient at some points and adequate at others.
Hydration by Phase
Menstrual: Increase water slightly due to blood loss. Warm liquids (herbal teas, broths) are soothing.
Follicular: Standard hydration is usually sufficient. Increase if you're more active.
Ovulation: Slightly increase to support cervical mucus production and manage temperature increase.
Luteal: Most important phase for hydration. Drinking more water actually reduces bloating by signaling your kidneys to release excess fluid. Aim for 9-10 glasses and reduce sodium.
Signs You're Not Drinking Enough
Dehydration symptoms can mimic PMS: headaches, fatigue, difficulty concentrating, constipation, dizziness.
Check urine color — pale yellow indicates good hydration. Dark yellow means you need more water.
Water-rich foods (watermelon, cucumber, oranges), herbal teas, and coconut water all count toward your intake. Add lemon, lime, or mint to water for flavor without added sugar.
