Drinking 1-2 Bottles of Water on Waking May Harm Kidneys

Kidney Health: Drinking water after waking up is healthy, but having 1–2 bottles at once can strain your kidneys. Start with one glass and sip more through the day.

Drinking Water for Kidney Health: How Much Is Too Much in the Morning?

Water plays a vital role in keeping the kidneys healthy. Adequate hydration helps flush out toxins from the body, making it easier for the kidneys to filter waste without overworking. Experts recommend drinking around 3 liters of water daily, which can also include other healthy liquids. Warm water in the morning is considered beneficial for digestion and overall health, but gulping down large quantities at once—especially right after waking up—can actually harm the kidneys.

Many people make the mistake of drinking one or two full bottles of water immediately after getting out of bed. According to doctors, this habit puts unnecessary strain on the kidneys. Dr. Sanjeev Saxena, Head of Nephrology at PSRI, explains that instead of chugging large amounts, you should start your day with 1–2 glasses of warm water. This is enough to hydrate the body and activate internal organs without causing pressure on the kidneys.

How Much Water Should You Drink in a Day?

To maintain healthy kidneys, a balanced diet and proper hydration are essential. On average, 3 liters of water per day is sufficient for most adults. This helps the kidneys efficiently filter out harmful substances. However, many people—especially those working in air-conditioned offices—forget to drink enough water throughout the day.

You can monitor your hydration level through your urine. If you produce around 2 liters of urine daily, you’re likely drinking enough water. If it’s significantly less, it’s a sign you need to increase your intake. Inadequate hydration can lead to toxin buildup, affecting overall health.

The Right Way to Drink Water

Instead of drinking large amounts at once, space your water intake throughout the day. For example:

Morning: 2 glasses of warm water after waking up
Before meals: 1 glass of water
30 minutes after meals: 1 glass of water
Before bedtime: 1 glass of warm water

If you work outdoors, in hot conditions, or sweat excessively, you should increase your water intake accordingly.

Bottom Line: Drinking water is essential for kidney health, but moderation is key. The best approach is to hydrate steadily throughout the day rather than overwhelming your kidneys with too much water at once, especially in the morning.
