Water is an essential element for us to maintain our health and life, and everyone is aware of this. Therefore, we often discuss what kind of water to drink is healthier, and how much water to drink every day is good for the body, but we rarely discuss the impact of drinking cups on health.
In 2020, an article titled “Study Finds: Glass Bottles Are 4 Times More Harmful than Plastic Bottles, Leading to More Environmental and Health Problems” became popular in the circle of friends, subverting everyone’s concept that glass is healthier.
So, are glass bottles really not as healthy as plastic bottles?
1. Is it true that glass bottles are 4 times more harmful than plastic bottles?
Don’t worry, let’s take a look at what this article says first.
Scientists have evaluated common beverage packaging such as plastic bottles and glass bottles. After considering factors such as energy consumption and resource exploitation, they finally believe that glass bottles are far more harmful than plastic bottles, nearly four times more harmful.
But note that this does not refer to the seriousness of the impact on human health and the environment when the glass bottle is used up, but also refers to the fact that it can consume more resources and energy during the production process. For example, it needs to mine soda ash and silica sand. , dolomite and other materials, and if these substances are excessively exploited, the consequences will be relatively serious, which may cause dust pollution, pollution of rivers in the surrounding area, etc.; or sulfur dioxide, carbon dioxide and other gases will be produced when making glass, do not underestimate these Gas, which is the “culprit behind the scenes” that triggers the greenhouse effect, can cause global climate anomalies; and these consequences are obviously much more serious than the harm caused by plastic.
Therefore, evaluating which of glass bottles and plastic bottles is more harmful depends on your perspective.
If you only consider it from the perspective of drinking water, drinking water from a glass is actually very healthy.
Because the glass does not add any messy things such as chemicals during the high-temperature firing process, so you don’t have to worry about “mixing” things in when drinking water; and the surface of the glass is relatively smooth and adheres to the Impurities on the surface are easy to clean, so you can consider drinking water from a glass.
2. “Hot water goes in, poisonous water goes out”, does the thermos cup also cause cancer?
In 2020, CCTV News had a related report about the “insulation cup”. Yes, 19 models are unqualified because the content of heavy metals exceeds the standard.

It should be emphasized that the carcinogenicity of the thermos cup mentioned in the report refers to the substandard (severely exceeded metal) thermos cup, not all the thermos cups. Therefore, as long as you choose a qualified thermos cup, you can drink with peace of mind.
Generally speaking, if you buy and use a stainless steel liner thermos marked with “304″ or “316″, you can drink with confidence. However, when using a thermos cup to drink water, it is best to only use it for white water, not for juice, carbohydrate drinks and other liquids, because fruit juice is an acidic drink, which can aggravate the precipitation of heavy metals on the inner wall of the thermos cup; and carbonated drinks are easy to produce gas. As a result, the internal pressure rises, forming an instant high pressure, causing serious consequences such as the cork not being opened or the contents “spouting”, hurting people, etc.; therefore, it is best to only fill the thermos with plain water.
