If during your period you feel like your body is holding onto water, the pain is more intense than usual, or you simply don't feel comfortable in your own skin, hydration may be an important part of the answer. It's not just about drinking more water. It's about understanding how your body uses and needs fluids differently throughout your cycle, and giving it exactly what it needs at each phase.
NIH guidelines recommend women consume 2.7 liters of total water per day, but during menstruation and the luteal phase, that need can be even higher.
Why hydration reduces menstrual pain
Research shows that a lack of hydration increases pain sensitivity during the menstrual cycle. When you're well hydrated, the body produces more endorphins — its natural pain relievers — creating an analgesic effect that reduces pain perception. Put simply: staying properly hydrated is one of the simplest and most accessible interventions for making those days more manageable.
How your cycle hormones affect hydration and water retention
The main hormones of your cycle — estrogen, progesterone, luteinizing hormone, and follicle-stimulating hormone — don't stay constant. They shift continuously according to which phase your body is in:
- Follicular phase (days 1–14): Estrogen starts low but rises sharply toward the end of menstruation, along with luteinizing hormone. Progesterone stays low. Water retention in this phase is generally less pronounced.
- Luteal phase (days 15–28): Progesterone rises significantly. This is the phase where hormonal changes directly affect fluid regulation in the body: a hormone called arginine vasopressin (antidiuretic) increases water retention in the kidneys. Additionally, other hormones promote sodium accumulation, further worsening retention.
This explains why in the second half of the cycle, many women feel more bloating, heaviness, and general discomfort — it's not in your head, it's your biology.
Throughout the entire cycle, maintaining proper hydration helps eliminate excess retained fluid, support lymphatic drainage, and reduce the fatigue, lack of focus, and mood changes associated with each phase.
Hydration during menopause: what changes and how to adapt
Hydration is equally critical during menopause. A 2024 meta-analysis confirms that women in this stage have a 20% higher risk of chronic dehydration due to the decline in estrogen and its effect on renal sodium regulation. During menopause, hormonal imbalance affects fluid regulation and increases hydration needs — manifesting not only in dry skin but in more intense hot flashes, greater fatigue, and persistent water retention.
If you're navigating this stage, Santo Remedio's Hormonal Balance can help support natural hormonal balance while you hydrate correctly.
How to hydrate properly during each phase of your menstrual cycle
Beyond simply drinking more water, the key is mineral balance. Here's a practical plan:
Increase water intake — consistently: make it a habit to drink even when you don't feel thirsty. In the phases with more retention, your body needs more water to eliminate the excess, not less.
Replenish electrolytes: during the cycle, a mineral imbalance occurs — potassium, magnesium, and calcium drop while sodium increases. Santo Remedio's Hydration Plus is the most complete option for maintaining this balance throughout your entire cycle — providing essential electrolytes for real hydration, beyond water alone.
Prioritize magnesium: 2023–2024 research confirms that magnesium losses during menstruation directly contribute to cramps and mood changes. Santo Remedio's Magnesio can make a noticeable difference on those harder days.
Reduce sodium: replace table salt with spices, iodized salt, or seaweed salts. This not only reduces water retention but also increases iodine — a mineral that tends to drop during the first week of your period. Seafood and fish are also natural iodine sources.
Increase fiber and water through food: apples, raspberries, lettuce, squash, and mushrooms are rich in water and fiber that support gut transit and cellular hydration. Entalla Skinny Yummy Gummies are a practical and delicious way to add fiber to your daily routine. For mornings, Super Cafe provides energy with metabolic support.
Support your mood: the cycle doesn't only affect your body — it also affects how you feel emotionally. Ashwagandha and Té de Pasiflora are natural allies for the days when irritability and stress intensify.
Your body works in an incredibly intelligent way throughout every phase of your cycle. Giving it the right hydration and minerals at the right time is one of the most powerful ways to support it. You have time to make adjustments that make a real difference in how you feel every month.
Let's be healthier, together.
