Why We Should Be Concerned About Plastic: Insights from Dr. Dhanya Nambiar
Plastic has become an integral part of modern life, but its widespread use has led to unintended consequences, particularly in the form of microplastics. Dr. Dhanya Nambiar sheds light on the hidden dangers of plastic and why individuals should reconsider their daily plastic consumption.
The Hidden Threat of Microplastics
When plastic was first invented, it was primarily used for products like polyethylene bags. Over time, the definition of plastic has expanded to include various types, such as recyclable and reusable plastics. However, the major concern today is the breakdown of plastic into microplastics—tiny particles measuring less than five millimeters in size, often invisible to the naked eye.
These microplastics are now found everywhere: in water, air, food, and even on human skin. Dr. Nambiar warns that microplastics act as hormonal and gut disruptors, posing significant health risks.
Sources of Microplastics in Daily Life
Dr. Nambiar highlights several common sources of microplastics:
Cosmetics: Many face scrubs contain microbeads made of plastic, which enter water systems when washed down the drain.
Clothing: Synthetic fabrics like Lycra and polyester shed plastic fibers when washed, contaminating oceans and rivers. When worn, these fabrics also expose the skin to microplastics.
Plastic Water Bottles: Heated plastic bottles release microplastics into the water, which are then ingested. Dr. Nambiar strongly advises against drinking from plastic water bottles, especially those left in hot environments.
Takeaway Coffee Cups: Many disposable coffee cups contain plastic linings that leach chemicals into hot beverages, adding to plastic consumption.
The Impact on Health and the Environment
Microplastics disrupt the body's normal functions because they cannot be broken down or expelled efficiently. According to Dr. Nambiar, these particles can:
Affect liver function
Disrupt gut health
Interfere with hormonal balance
Accumulate in the brain, potentially leading to cognitive issues
Additionally, plastic pollution is detrimental to the environment. The breakdown of plastics in water systems affects marine life, and microplastics have been found in the food chain, posing risks to human health.
Rethinking Daily Habits
Dr. Nambiar suggests simple but effective ways to minimize exposure to microplastics:
Choose Natural Fabrics: Opt for clothing made of cotton (at least 40% or more) instead of synthetic materials.
Use Reusable Water Bottles: Replace plastic bottles with those made of stainless steel or copper.
Avoid Plastic-Lined Coffee Cups: Bring a reusable ceramic or stainless steel cup when purchasing coffee.
Reduce Plastic in Cosmetics: Look for skincare and hygiene products without microbeads or synthetic additives.
Adopt Sustainable Laundry Practices: Use cold water to wash synthetic clothes and consider a microplastic filter for washing machines.
Detoxifying the Body from Microplastics
While complete detoxification from microplastics is challenging, some theories suggest that prolonged fasting and clean eating may help reduce stored toxins in fat cells. However, Dr. Nambiar emphasizes that prevention is more effective than attempting to remove microplastics after exposure.
The Need for a Cultural Shift
Dr. Nambiar recalls a time when ceramic and reusable items were the norm, stressing that sustainability was once an inherent part of daily life. She urges individuals to prioritize reducing plastic use over recycling, as recycling processes remain inefficient. Her suggested hierarchy is:
Avoid plastic whenever possible.
Reduce plastic consumption.
Reuse plastic items before disposal.
Recycle only as a last resort.
Plastic pollution is not just an environmental issue but a serious health concern. Dr. Nambiar's insights underscore the urgent need for lifestyle changes to minimize plastic exposure. By making informed choices, individuals can protect their health and contribute to a cleaner, safer planet.
