Understanding Hydration During Menstruation: Can You Drink Too Much Water?

When it comes to periods, there are plenty of questions that arise, among which, one is about hydration. Is it possible to drink too much water during your period? How much is too much? And most importantly, how does hydration affect your menstrual cycle?

Hydration and The Menstrual Cycle: The Connection

The human body is about 60% water, and that water plays a critical role in maintaining bodily functions. During your menstrual cycle, hydration becomes even more critical. Your body goes through a lot of changes and losing fluids during your period can make you dehydrated. This can lead to headaches, fatigue, and even increase menstrual cramps.

Drinking plenty of water not only helps replace the lost fluid, but it can also alleviate bloating, a common premenstrual and menstrual symptom. When your body is dehydrated, it tends to hold onto water, resulting in bloating. By drinking more water, you help your body maintain a proper fluid balance, thereby reducing bloating.

Can You Drink Too Much Water During Your Period?

Yes, you can. Although it is essential to stay hydrated during your period, it is also possible to drink too much water. This condition is known as water intoxication or hyponatremia. When you consume too much water in a short period, your kidneys can’t excrete the excess water. The extra water can dilute the electrolytes in your blood, especially sodium, leading to low sodium levels. Sodium plays a vital role in your body, helping your nerves and muscles function correctly. Low sodium levels can lead to nausea, headache, confusion, seizures, coma, or even death in severe cases.

It’s important to note that cases of hyponatremia are relatively rare and typically occur when individuals drink extreme amounts of water in a short time.

How Much Water Should You Drink During Your Period?

Staying hydrated is crucial during your period, but how much water should you drink? The general recommendation is to drink at least eight 8-ounce glasses of water per day, which equals about 2 liters, or half a gallon. This is known as the 8×8 rule and is easy to remember.

However, during your period, you might need to drink a little more than this to counteract the fluid loss. Listen to your body; if you’re thirsty, drink, and remember to increase your water intake if you’re experiencing symptoms of dehydration, such as dry mouth, fatigue, or dizziness.

Keep in mind that hydration doesn’t only come from water. Fruits, vegetables, and herbal teas also contribute to your daily fluid intake.

Tips to Stay Hydrated During Your Period

  • Start your day with water: Before you have your first cup of coffee, have a glass of water.
  • Keep a water bottle handy: This can be especially useful when you’re on the go or at work.
  • Eat water-rich foods: Foods like cucumbers, oranges, watermelon, and strawberries can help boost your hydration levels.
  • Avoid or limit diuretics: Beverages like coffee, alcohol, and certain teas can dehydrate your body. Try to limit your intake of these, especially during your period.


While it’s important to stay hydrated during your period, you also need to ensure that you’re not overdoing it. Maintaining a balanced water intake can contribute to your overall health and comfort during your menstrual cycle. Listen to your body’s needs, stay hydrated, but remember not to over hydrate. Your body will thank you for it!
