For this reason, you should never reuse a plastic bottle after the water has been used up

This is a habit that has been adopted by a large number of people, and yet it could not be worse. Find out why you shouldn’t refill a plastic water bottle after you’ve emptied it. This gesture can expose you to dangers to your health!

When we run out of our plastic water bottle, we may be tempted to refill it. Only this gesture can harm our body. One thing is for sure: you won’t do this again if you know what happens when you start this habit.

On hot days we need to drink lots of water to stay hydrated. Only if you are one of those people who reuse water bottles could you harm your health. This is because single-use plastic bottles can contain toxic compounds and harmful bacteria.

types of plastic bottles

Most water bottle packaging has a number printed inside a triangle to indicate what type of plastic it is. You can also use this number to determine how safe it is to reuse.

Here are three of the most common types of plastic found in water bottles.

Polyethylene terephthalate (PETE or PET):

If you notice a “1” on your bottle, it means polyethylene terephthalate. This lightweight plastic is useful for water bottles and containers like sauce bottles, nut butter containers, and other food packaging.

High Density Polyethylene (HDPE):

If your bottle shows a “2”, the plastic is High Density Polyethylene (HDPE). HDPE is a stronger and more durable plastic. This makes it a good material for detergent bottles, soap bottles and 3.5L liquid containers.

The “7” is the identification code for plastic materials that do not fit into any other category. Some water bottles in this category may contain Bisphenol A, also known as BPA. This is a chemical that has been linked to disruptions in the endocrine system, which is responsible for regulating hormones. Many people avoid products that contain BPA because of its potential hormonal effects.

chemical leaching

A common problem when reusing bottled water is chemical leaching. This is when the chemicals in the plastic mix with the liquid you put in it. But with the right storage and the right plastic, this is usually not a problem with plastic bottles.

However, when these types of plastic are stored at extremely high temperatures, there is a risk of leaching a chemical called antimony. However, the risk of chemical leaching is low if you store the bottles properly. It is best to store these bottles at room temperature and out of direct sunlight to minimize all of these risks.

Plastic bottles and the composition of bacteria

Plastic bottles can harbor harmful bacteria, which is why most manufacturers recommend using them only once. Bacterial growth in bottled water is a much bigger problem than chemical leaching.

Bacterial growth can occur quickly if you put your mouth to your bottle during normal use. Even room temperature drinks can allow bacteria to grow throughout the day. It’s best to reuse plastic water bottles and wash them thoroughly as germs spread quickly.

These chemicals can negatively impact hormone balance, but the potential dangers of plastic water bottles don’t stop there.

To stay safely hydrated, avoid reusing disposable bottles. It is better to recycle after drinking or buy a BPA-free plastic bottle or a glass bottle.
