When tap water has an unusual smell or taste, many people turn to bottled water. While bottled mineral water may taste better, it comes with an expiration date. This date typically applies to the plastic bottles themselves when filled with natural mineral water. Increasing research shows that microplastics—tiny, invisible plastic particles—can leach into the water from these bottles. These particles, sometimes numbering up to 100,000 per bottle, enter the body and interfere with its systems, particularly the hormonal system, negatively impacting fertility.
Microplastics cause oxidative stress, disrupting the balance between harmful free radicals and antioxidants, which can degrade egg quality (2) and alter hormone levels (3). Due to their small size, they can easily penetrate reproductive cells and tissues, potentially affecting the immune system (3)(4). Therefore, reducing plastic bottle usage is not just an environmental issue; it could also influence family planning. This is one of the reasons why relying solely on bottled water isn’t ideal. Opt for tap water if it’s good quality, or consider investing in a water filter.
