Tea bags are a convenient option but hide health and environmental risks. Most tea bags contain plastics, adhesives, and chemicals that release harmful substances when hot water is applied. Some research indicates that steeping some tea bags can release billions of microplastics, which have been associated with inflammation and even endocrine disruption issues. Additionally, chemicals such as epichlorohydrin and bleaching agents may leach toxins into the beverage, thereby raising cancer concerns. On the environmental level, non-biodegradable tea bags contribute to plastic pollution that eventually harms ecosystems. Loosening tea habit: Opt for loose-leaf teas, biodegradable tea bags or environtmentally friendly brands.
