Most of us don’t think about our kidneys until something goes wrong. These two bean-shaped organs quietly filter about 50 gallons of blood every single day, helping remove waste, balance fluids, and regulate blood pressure. But what if some of our everyday habits are unknowingly making their job harder? While serious kidney problems often take years to develop, small daily choices can have a big impact over time. In this article, we’ll explore 10 common habits that may strain your kidneys—and simple tips to protect these vital organs for the long run.
Why Kidney Health Matters
Your kidneys are essential to your body’s natural detox system. When they’re functioning well, you likely feel fine without even thinking about them. But when they’re under stress, waste can build up in the body and silently impact your energy, hydration, and even heart health.
According to the National Kidney Foundation, more than 1 in 7 American adults have chronic kidney disease—and many don’t even know it. That’s why it’s so important to be mindful of the small things we do every day that can either help or harm these hardworking organs.
Let’s take a closer look at which daily habits may quietly put your kidney health at risk.
1. Not Drinking Enough Water
Hydration is one of the simplest yet most overlooked ways to support your kidneys.
When you don’t drink enough water, your kidneys have to work harder to filter waste and maintain fluid balance. Over time, this strain may contribute to the development of kidney stones or other issues.
Helpful tip:
-
Aim for 6–8 cups of water a day, more if you’re physically active or in hot weather
-
Choose water over sugary drinks to avoid added strain
2. Eating Too Much Salt
A high-sodium diet can increase blood pressure, which is one of the leading causes of kidney damage. Many Americans consume far more sodium than recommended, especially from processed and fast foods.
To reduce salt intake:
-
Read labels on canned goods, sauces, and snacks
-
Cook at home using herbs and spices instead of salt
-
Be mindful of takeout meals, which often contain high levels of sodium
3. Relying on Over-the-Counter Pain Relievers
Using medications like ibuprofen or naproxen occasionally is generally safe, but long-term or high-dose use may harm kidney tissue, especially if you’re dehydrated or already have underlying conditions.
Safer practices include:
-
Talking to your doctor about long-term pain management
-
Staying hydrated when using any medications
-
Considering natural alternatives like warm compresses or light stretching when possible
4. Skipping Fruits and Vegetables
Colorful fruits and vegetables are rich in antioxidants, potassium, and fiber—all of which help support kidney health. A diet lacking in these foods may increase your risk of metabolic imbalances, which can eventually impact your kidneys.
Simple ways to add more produce:
-
Include a side salad or steamed veggies with lunch and dinner
-
Snack on apples, cucumbers, or berries
-
Blend spinach or kale into a smoothie
5. Eating Too Much Processed Meat
High intake of processed meats—like bacon, sausages, and deli slices—has been linked to higher levels of sodium and phosphorus, which can be hard on the kidneys.
Healthier swaps include:
-
Grilled chicken, salmon, or legumes
-
Home-cooked meals with fresh ingredients
-
Limiting red meat to a few times per week
6. Ignoring High Blood Pressure
High blood pressure is a major risk factor for kidney damage, yet many people don’t experience obvious symptoms until it’s advanced.
To manage blood pressure naturally:
-
Reduce sodium and processed foods
-
Stay active with walking, stretching, or low-impact exercises
-
Monitor your blood pressure at home regularly if advised by your doctor
7. Holding In Urine Frequently
While it’s not dangerous occasionally, making a habit of holding in urine for long periods may increase the risk of urinary tract infections and pressure on the kidneys.
Quick tips:
-
Use the bathroom when you feel the urge
-
Stay hydrated so your body can flush out toxins regularly
-
If you’re frequently unable to go, consider speaking with your healthcare provider
8. Consuming Too Much Sugar
Sugary drinks and desserts can lead to weight gain, insulin resistance, and elevated blood sugar—all of which are risk factors for kidney disease, particularly diabetes-related kidney damage.
Better choices include:
-
Choosing water, herbal teas, or sparkling water with lemon
-
Reading food labels to spot hidden sugars
-
Treating sweets as occasional indulgences instead of daily staples
9. Smoking or Exposure to Secondhand Smoke
Smoking reduces blood flow to the kidneys and increases the risk of kidney disease over time. Even secondhand smoke exposure can contribute to overall health decline.
If you’re trying to quit:
-
Seek support groups or talk to your doctor about cessation plans
-
Avoid places where you’re exposed to smoke
-
Replace the smoking habit with deep breathing, walking, or chewing gum
10. Not Getting Enough Sleep
Your body repairs itself during sleep—including the kidneys. Chronic sleep deprivation may contribute to inflammation and metabolic imbalances that strain kidney function.
For better rest:
-
Aim for 7–8 hours of sleep per night
-
Create a calming bedtime routine
-
Limit screen time an hour before sleep
Bonus: When to Get Your Kidneys Checked
If you have risk factors like high blood pressure, diabetes, a family history of kidney problems, or are over age 60, it’s a good idea to ask your doctor about kidney screening. A simple urine test or blood test can help detect early signs of trouble—even before symptoms appear.
