Why is there an expiration date on packaged water? Read when drinking bottled water becomes dangerous.

News Topical, Digital Desk : We drink water every day, but have you ever wondered if water can expire? Yes, it sounds strange, because water is a natural substance that doesn't spoil. However, if stored improperly or in the wrong container, it can be harmful to our health. Let's find out how.

Does bottled water really expire?

Water bottles often have an expiration date printed on them. This date is usually two years after bottling, but the truth is that the water itself doesn't spoil; rather, the plastic in the bottle begins to dissolve over time.

In fact, chemicals like bisphenol-A (BPA) and antimony can slowly leach into water from plastic bottles, especially when the bottle is exposed to sunlight or heat. Consuming such water over a long period of time can affect the body's hormonal balance, immunity, and digestive system.

How safe are reusable bottles?

If you reuse water bottles frequently, be careful. Once opened, bacteria and mold can quickly grow in the water. Every time we drink from the bottle, germs from our mouths enter the bottle, and within a few days, a layer called biofilm begins to form on the walls.

This is why old bottles can sometimes smell bad or the water can taste strange. Drinking this water can cause stomach pain, diarrhea, or even infection.

It is important to keep these things in mind

If you want your water to always be safe, it is important to adopt some simple habits-

• Wash your reusable bottle daily with hot water and soap.
• Clean with vinegar or baking soda once a week to prevent bacteria from growing.
• Use steel or glass bottles, as chemicals do not dissolve in them and bacteria also grow less in them.
• Avoid leaving bottles in sunlight or hot places, especially in the car for long periods of time.
• If the water tastes or smells strange, appears sticky, or has mold, throw it away immediately.

Water itself isn't perishable, but its storage method and container determine its safety. If you regularly clean your bottles, drink fresh water, and don't keep old water for long, you can stay hydrated without worry.
