Drinking water that’s been sitting in a bottle for an extended period can pose health risks due to potential bacterial growth and chemical leaching. It’s essential to understand how long water can be safely stored and the factors that impact its quality.
How Long Can You Safely Drink Bottled Water?
Bottled water is generally safe to drink if consumed within a few days of opening. Unopened bottles can last indefinitely if stored in a cool, dark place. However, once opened, the water should ideally be consumed within a week to prevent contamination.
What Happens to Water in a Bottle Over Time?
Bacterial Growth: Once a bottle is opened, bacteria from the air or your mouth can enter the water, leading to potential contamination. This is especially true if the bottle is left at room temperature or exposed to sunlight.
Chemical Leaching: Plastic bottles can release chemicals like BPA or phthalates into the water over time, especially when exposed to heat. These chemicals have been linked to health issues, making it crucial to store bottled water properly.
Tips for Storing Bottled Water Safely
- Keep it Cool: Store bottles in a cool, dark place to minimize bacterial growth and chemical leaching.
- Avoid Sunlight: Direct sunlight can increase the temperature inside the bottle, accelerating chemical leaching.
- Use Glass or Stainless Steel: Consider using reusable glass or stainless steel bottles to avoid chemical exposure from plastics.
Is It Safe to Reuse Plastic Water Bottles?
Reusing plastic water bottles is generally not recommended due to the risk of bacterial contamination and chemical leaching. If you must reuse a plastic bottle, wash it thoroughly with soap and hot water after every use.
How to Properly Clean Reusable Bottles
- Rinse with Hot Water: After each use, rinse your bottle with hot water to remove any residue.
- Use Soap: Apply a small amount of dish soap and scrub the interior with a bottle brush.
- Air Dry: Allow the bottle to air dry completely before storing or refilling.

How Does Temperature Affect Bottled Water?
High temperatures can cause plastic bottles to release chemicals into the water and promote bacterial growth. Always store bottled water in a cool environment.
Is It Better to Drink Tap Water or Bottled Water?
Both tap and bottled water have their pros and cons. Tap water is more environmentally friendly and cost-effective, while bottled water is convenient. Ensure your tap water is filtered if you’re concerned about contaminants.
Conclusion
In summary, while drinking water from a bottle that’s been sitting for a short period is generally safe, it’s crucial to be mindful of storage conditions to avoid health risks. Opt for reusable bottles made of safer materials like glass or stainless steel, and always prioritize proper cleaning practices. By understanding the potential risks and taking preventive measures, you can enjoy safe and healthy hydration.
