Why should we avoid Hot Tea in Plastic Cup
Millions of people all around the world love drinking hot tea. It provides warmth, comfort, and a refreshing start to the day. Many of us might not think much about the sort of cup we use when we’re sipping on a warm cup of tea. However, it’s important to consider the materials we use to drink hot tea. Even if they are convenient, plastic cups can be dangerous for your health if they are exposed to extreme temperatures. In recent years, concerns have been raised regarding the potential hazards of consuming hot tea in plastic cups. In this post, we’ll look at the reasons why should we avoid hot tea in plastic cup and some alternatives that can guarantee both taste and safety.
Plastic cups are frequently used to drink hot tea due to their lightweight and low cost. However, the materials used to make plastic cups can harm the environment and our health. When it comes to choosing the correct container for our hot beverages, it is critical to understand these hazards and make informed decisions.
Understanding Plastic Composition
Before we know why should we avoid hot tea in plastic cup, let’s first understand about composition of plastic. Polymers generated from petrochemicals are used to create the synthetic substance known as plastic. Most plastic types, including Styrene from polystyrene, plasticizers from PVC (polyvinyl chloride), and Acetaldehyde from PET (polyethylene terephthalate), have been observed to contaminate food. Polystyrene and polyethylene terephthalate (PET) are two common synthetic polymers used to make plastic cups. These materials are a preferred option for disposable cups since they are affordable, lightweight, and strong. When exposed to hot beverages (such hot chocolate, tea, or coffee), plastic’s composition may cause more concern than when it is exposed to cold beverages.
Harmful Effects of Hot Tea on Plastic cup
-
Potential Chemical Leaching
One of the main issues with plastic is its tendency to leach dangerous chemicals into the substances with which it comes into contact. When hot tea is poured into a plastic cup, the heat may accelerate the leaching process, causing trace amounts of chemicals from the plastic to transfer into the tea, which can then be swallowed when consumed. The higher the temperature of the liquid, the greater the possibility of chemical transfer.
As polystyrene is the main component of plastic cups, the leaching of plastic material is styrene monomers, and styrene enters the human body and metabolizes through multiple pathways. The most significant metabolic pathway in humans is the mono-oxygenize system in liver microsomes, which uses cytochrome P450 to convert styrene to styrene epoxide. The biotransformation of styrene monomer to styrene epoxide and the generation of peroxide radicals is potentially dangerous for human health. With a hot beverage, a polystyrene cup containing around 0.025% styrene can be transmitted to the human body. According to the findings of a 2014 study, the leaching of plastics into hot tea and the amount of plastic material leached was in the range of 1.5 – 2.0 mg per cup from <1gram of cup. The temperature and duration are the main factors affecting how much plastic is leached into hot tea.

Toxins release
Plastic cups may additionally contain additives like colorants and stabilizers that can be released when comes in contact with heat. These additives may not be meant for direct intake and can be dangerous when consumed in significant amounts. Toxins might be released into your tea due to the environment that is created by the combination of heat and plastic cups.
Health Hazards of Drinking Hot Tea in Plastic Cups
- Bisphenol A, and Phthalates: An Endocrine Disruptor
Bisphenol A (BPA) is a chemical frequently used in the manufacturing of plastics, while phthalates are a different group of chemicals that are used to soften plastics. BPA and phthalates are also referred to as endocrine-disrupting chemicals (EDCs), due to their capacity to modulate the endocrine system. Endocrine disruptors are substances that have the potential to interfere with the regular functioning of hormones in the body. When the hot beverage comes into contact with plastic cups, the heat may cause the leaching of these chemicals into the beverage. Long-term exposure to endocrine disruptors may cause hormonal imbalances, alter normal breast development, reproductive issues, and some types of cancer. Plastic cups with a high BPA concentration weaken our body’s natural immunity. To reduce the risk of consuming these dangerous substances, it is best to avoid using plastic cups for hot tea.
- Carcinogenic Concerns
Formaldehyde is a preservative found in many disposable tea cups. Styrene and formaldehyde are two compounds that can be found in plastic cups that have been identified by numerous health organizations as potentially carcinogenic. When these chemicals are exposed to hot tea, they are more likely to leach into the beverage, raising the chance of long-term health consequences. According to a National Institute of Health report, formaldehyde has been associated with both leukemia and a rare form of nasal cancer (National Toxicology Service, U.S. Department of Health and Human Services, 2014).
Styrene exposure over a prolonged period of time can lead to:
-
- Accumulation of Styrene in the brain tissues, spinal cord, and peripheral nerves has a neurotoxic effect that results in fatigue, behavioral changes such as uneasiness and anxiety, and other chronic disorders of the nervous system.
- Chronic styrene exposure may the liver and nerve tissues.
- The newborn may be exposed to styrene through breast milk.
Environmental Impact
Plastic cups not only pose health risks but also significantly worsen environmental pollution. Plastic needs hundreds of years to decompose and is not biodegradable. By using plastic cups for hot tea, we contribute to the accumulation of plastic garbage which ends up in landfills or pollutes our oceans. We can lessen our carbon footprint and safeguard the environment for future generations by avoiding the use of plastic cups.
Safer Alternatives for Enjoying Hot Tea
It is essential to take into account alternate materials for your cups in order to reduce the potential risks related to drinking hot tea. Here are some safer alternatives:
- Porcelain and Ceramic Cups
For sipping hot tea, porcelain, and ceramic cups are great choices. Ceramic is a non-reactive material, so no undesirable flavours or chemicals are transmitted to your tea. These cups also retain heat well, helping you to enjoy your tea at the ideal temperature for an extended period of time.
- Glass Cups
Glass cups are a good alternative to plastic for drinking hot tea. They are inert, which means they do not leach any dangerous compounds into the beverage. Glass additionally retains heat well and being transparent, allowing you to completely appreciate the color and aroma of tea. Glass cups are also easy to clean and reuse, making them eco-friendly.
- Stainless-steel cups
Hot tea is best served in stainless steel cups because of their durability and insulating properties. They can prevent any chemicals from leaking into the tea while keeping it heated for a long time. Stainless steel is a safe and hygienic material that cannot retain or transfer flavors, allowing you to enjoy the pure taste of your tea.
