2 secrets about plastic bottles of water that many people would wish for 'I'd rather not know'

Do not just drink it all and then pour new water to drink it day after day. Sometimes such things accidentally affect your health without your knowledge.

Plastic bottles are popular for us thanks to their low cost, convenience and reuse.

However, how to use them well and safely is something few people think about. Let's take a look at some tips on using plastic bottles to ensure your own health.

1. Not all bottles can be reused

Depending on the plastic material, bottles can decompose to create many dangerous chemicals mixed into the water. So, not all plastic bottles can be reused.

To know what kind of reuse is allowed, please pay attention to the symbols at the bottom of the bottle.

If the bottle has a No. 1 label (PET or PETE): it is only safe for one use. When it comes to air oxygen or high temperatures (like sunlight), these types of bottles decompose into toxic substances.

Avoid using plastics with labels labeled 3 or 7 (PVC and PC), because they are two toxic chemicals and easily mixed in food and drinking water. Long-term use of this bottle may even cause serious health problems.

Plastic bottles made from polyethylene (numbers 2 and 4), and polypropylene (5 and PP) are suitable for repeated use. However, keep in mind that they are only safe if you use them to store cold water and must clean them regularly.

2. The amount of bacteria is equal . the toilet

According to scientists, drinking water from a used plastic bottle may contain a quantity of bacteria equivalent to dog toys, even . toilet seats. The amount of bacteria in those bottles often exceeds the prescribed safety threshold.

Why? Because we have created the perfect development environment for bacteria by grasping the bottle by hand dirty, then re-use it without going through the cleaning step, or cleaning too sketchily.

To limit this situation, wash the plastic bottle regularly with warm soapy water, vinegar or bactericidal mouthwash. In addition, a study has shown that most bacteria are usually in the screw cap - where you cannot wash it well. So to be safe, drink water with a straw.
