While, technically, it is, but the packaging might make it harmful for us. As per a November 2024 study published in Chemosphere, researchers tested three different brands of tea bags for exposure of microplastics, which are also degraded plastic bits that do not breakdown and found that it could impact human health.
The team found that brewing tea in polypropylene, essentially plastic bags, or a common tea bag material actually released over a billion particle per milliliter of tea. In fact, what we think as the paper bags, made of cellulose and mesh nylon bags also shed millions of plastic particle per milliliter.
John Meeker, a professor of Environmental Health Sciences and Global Public Health at the University of Michigan School of Public Health said finding such high amounts of micro and nanoplastics in a product that is supposed to be consumed is a cause of concern.
The researchers first extracted plastics from brewed tea and then exposed them to human intestinal cells that absorbed the plastic particles. It showed that microplastics could remain in the body even after drinking the tea.
The study author Alba Garcia-Rodriguez, a researcher in the Department of Genetics and Microbiology at the Universitat Autonoma de Barcelona said the research calls attention to the path of substantial exposure to plastic particles which are also found in everyday lives. "We have to be concerned about the huge number of single-use plastic that humans are exposed to daily," she said.
Similar tests have been conducted previously. In 2019, a Canadian study was the first one to test nylon and polyethylene tea bags which released 11.6 billion microplastics and 3.1 nanoplastics, measuring less than a micron into a single cup of tea.
In another study from 2023, conducted by Garcia-Redriguez and colleagues, one brand of tea bags were tested that was made of polylactic acid, a biodegradable plant-based plastic. The study showed that it released 1 million nanoplastic particles per tea bag.
For this 2024 study, the research team set broadened their scope by testing out for various materials. They obtained empty tea bags made from three commonly used materials: polypropylene, nylon, and cellulose.
The team simulated typical tea-brewing conditions (without tea leaves) by steeping the bags in sterile water heated to 95°C (203°F) while stirring continuously. They then measured how many plastic particles each material released.
The results revealed that polypropylene bags shed the highest amount of microplastics—approximately 1.2 billion particles. Cellulose paper bags came next, releasing 135 million particles per milliliter, while nylon mesh bags released 8.18 million particles.
The study revealed that hot temperature water exposure and also the stirring of spoon can cause tea bags to "leach plastics".
When the plastics were exposed to humans, it showed that cells absorbed the microplastics, including the mucus cells, as they had the highest uptake of particles. After 24 hours, the particles reached the nucleus of the cells, which houses the DNA.
Experts find the results concerning, as ingested microplastics could enter the bloodstream after targeting tissues in the gastrointestinal tract, potentially spreading to other organs. While chemicals added during plastic production have been linked to issues like endocrine disruption and cancer, the health effects of ingested microplastics remain unclear. Scientists caution against drawing conclusions, noting that human studies on microplastics are still limited and much more research is needed.
How can one reduce the exposure to plastics? The best way possible is by buying loose leaf, even when you are using green tea, which, is mostly used in tea bags, as a way to make it instantly. In case you are in rush, you can always use the steel infuser to use it as a replacement of plastic tea bags for an instant cup of tea.

Sugary drinks are a very soothing option in summer, but come with several health-related issues like diabetes, fatty liver, and heart disease, to name a few. And now this list is getting a new addition, as a new study claims that sugary beverages can cause brain aging. This research is linked to the Framingham Heart Study.
As the Indian summer is in full sway, the demand for cold sugary drinks is also rising along with it. During the hot summer, people use these beverages as cooling drinks, and consumption also goes through the roof.
The researchers from the Boston University School of Medicine studied participants in the Framingham Heart Study Offspring and the Third Generation Study. The research was done on the possible impacts that sugar-sweetened beverages (SSBs) and artificially sweetened beverages (ASBs) have on the brain.
The study finds that consuming a large amount of sugary drinks was associated with a smaller total size of the brain and reduced volume of the hippocampus, which is a critical region in the brain essential for learning and memory.
The research points out that consuming too many sugary drinks can lead to inflammation, poor blood vessel function, and high blood sugar, which in turn might harm the brain.
Sugary drinks or sugar-sweetened beverages (SSBs) are drinks that are added with sugar, sweeteners, or syrups. Some of the common sugary beverages are carbonated soft drinks, energy or sports drinks, and fruit-flavored drinks.
Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.
You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor. Make this your new habit.

The data from the Centers for Disease Control and Prevention (CDC) shows that almost half the population of the United States has high blood pressure, numbering around 119.9 million people, who are suffering from this disease. The data also reveals that over 660,000 deaths occur every year. Thus, keeping your blood pressure under check is a necessity, and beetroot, along with some leafy greens, can help you in this.
A recent study conducted by the University of Exeter found that drinking beetroot juice twice daily can help lower blood pressure in older adults in just a fortnight. The findings of this study were published in the journal Free Radical Biology and Medicine.
The study was conducted with 75 volunteers from different age groups. They belong to the age bracket of 30s to 60s and 70s. The researchers asked each person to complete two separate two-week trials. In one of the two weeks, they were given nitrate-rich beetroot juice, and in the other week, it changed to a placebo version with the nitrate removed.

Summer brings not just a temperature change, but also a change in energy. Ayurveda, the ancient Indian study of life and health, says that each season has its main dosha, or bio-energetic force. Summer is the time of Pitta — the dosha ruled by the elements of fire and water. Dr Mandeep Singh Basu, Director, Jagat Pharma, in an interview with Health and Me, listed some of the best desi foods that can help you beat the heat and stay hydrated even in peak summer.
In summer, the goal is to favour sheeta (cooling), laghu (light), and snigdha (mildly unctuous) foods. They balance Pitta's hot, furious, and acute qualities. In Ayurveda, there are six tastes: sweet, sour, salty, pungent, bitter, and astringent. All six tastes have a relationship with Pitta. Sweet, bitter, and astringent are the flavours of summer.
Coconut Water
The most famous summer drink in Ayurveda is probably coconut water. It is categorised as a tridoshic drink. It balances all three doshas but is highly prized for its capacity to soothe Pitta and restore ojas, the vital essence of immunity and vigour. Coconut water is packed with natural electrolytes, potassium, magnesium, and sodium, replenishing what perspiration leaves behind.
Drink fresh tender coconut water in the mid-morning or as an afternoon refresher. Do not drink it cold from the refrigerator. Room temperature or slightly cool coconut water is recommended for the best absorption.
Cucumber
More than 95% of a cucumber is water, and it is known for its cooling energy, which Ayurveda has long understood. It cools internal heat, soothes irritated digestive tissue, and improves renal function, all of which are important in summer when the body is under heat stress.
Modern nutritionists would say that cucumber is also a source of silica for skin health, vitamin K, and antioxidants like cucurbitacins. But in Ayurveda, its Pitta-shamaka (Pitta-pacifying) quality is most appreciated — it literally cools the gut, the blood, and the skin from the inside out.
Have cucumber slices with a pinch of rock salt (sendha namak) and fresh mint. Mix it into raita with cooling coriander and cumin. According to Ayurveda, you should not consume cucumber at night as it may slow digestion.
Watermelon
Tarbuj is known for its sweet, cooling, and hydrating nature. One of the most generous gifts of summer is watermelon, a fruit that contains approximately 92% water and is a source of lycopene, a potent antioxidant that helps protect against UV damage. Watermelon is a natural Pitta pacifier and a mild urinary tract detoxifier in Ayurveda.
It is classed as sheeta virya (cold potency) and is considered helpful for burning sensations in the body, such as heartburn, skin redness, and excessive thirst. The seeds, which are generally discarded, are treasured in Ayurveda. They are dried, powdered, and consumed as a kidney tonic.
Eat watermelon on its own. It is best eaten alone in the late morning. Ayurveda also recommends against pairing watermelon with dairy, cereals, or other fruits because it digests best alone. A squeeze of lime and a pinch of black salt may be added for flavour.
Mint
Ayurvedic Quality: Cool, light, pungent in taste but cooling in effect.
Mint is one of Ayurveda's most fascinating paradoxes — it tastes pungent (which would ordinarily aggravate Pitta), but its virya, or post-digestive potency, is deeply cooling. This makes it uniquely suited for summer use. It stimulates digestion without generating heat, relieves nausea, clears the respiratory tract, and cools the mind. Modern science confirms that its menthol content activates cold-sensing receptors in the body, creating a genuine cooling sensation.
You can consume mint in the form of freshly brewed mint tea (cooled to room temperature), blend it into chutneys with coriander and coconut, or add it to cooling drinks like aam panna or shikanji. Mint-infused water kept in a clay pot (matka) is a classic Ayurvedic cooling remedy.
Amla (Indian Gooseberry)
Amla is one of the most remarkable foods in the Ayurvedic pharmacopoeia. Its virya is cooling, meaning it has a unique ability to soothe rather than inflame, even though it is sour — a taste that normally aggravates Pitta. It is the main constituent in two of the most revered Ayurvedic formulations, Chyawanprash and Triphala.
Amla is the richest natural source of vitamin C among fruits, containing about 600–700 mg per 100 grams. A large proportion of this vitamin C is heat-stable because tannins in the berry protect it during digestion and cooking. It safeguards the liver, enhances skin clarity, and bolsters immunity — all of which are challenged by the demands of summer.
