Summary of Key Points
  • While concerns have been raised about EMFs (electromagnetic fields) and 5G, the science is still evolving. Taking simple steps to reduce our exposure—like keeping our distance from devices or switching to airplane mode—is a highly effective approach.
  • While it's difficult to completely avoid pesticide residues, we can definitely reduce our exposure by taking simple steps like washing our produce, peeling it, and using the EWG's list as a guide when we shop. Research also suggests that washing with ingredients like baking soda can help reduce these residues.
  • Because there are concerns that phthalates and BPA can disrupt our endocrine system, it's best to avoid using plastic when heating food. Instead, reaching for glass or stainless steel containers is a much better choice (as noted in reports from sources like Harvard Health).
  • Because PM2.5 is known to affect our heart and lungs, it's highly effective to wear an N95 or KN95-equivalent mask when you're outdoors and to use a HEPA filter indoors.

Invisible risks are right next to us in our everyday lives.

In our everyday lives, the things that can negatively impact our health aren't always visible. The smartphones and appliances we use daily, the vegetables we buy at the supermarket, our food storage containers, and even the air outside—hidden within these are things like EMFs, pesticide residues, plastic-derived chemicals, and PM2.5 that can affect our health without us even realizing it. In this article, based on the latest findings, we have put together a simple, easy-to-understand guide on what you need to know and the steps you can take starting today. We will also be sharing our own personal experiences and how we felt after trying a few of these out in our own daily routines.

EMFs and 5G — Scary, But Here's How to Reduce Your Exposure Without the Stress

What is considered to be the problem?

While some studies raise concerns about the potential impact of electromagnetic fields (EMF) emitted by our computers, smartphones, and wireless devices on our DNA, nervous system, immune system, and heart, it remains an area where the science isn't completely settled. The debate surrounding the safety of 5G technology is also ongoing, with additional research and regulatory reviews currently taking place all over the world.

Practical Strategies

  • Avoid carrying your phone in your pocket, and keep it away from your bedside when you sleep.
  • When you aren't using your device, put it in airplane mode or turn it off. We also put ours in airplane mode at night, and we've felt a real improvement in our sleep quality.
  • When talking on the phone, use the speakerphone or wired earphones to reduce exposure to your head.
  • For fixed sources like routers and base stations, being mindful of where they are placed and keeping your distance is the simplest and most effective approach.

Pesticide Residues — It May Be Hard to Eliminate Them Completely, but Let's Find Ways to "Reduce" Them

Risks and the Current Situation

While pesticides are essential for growing crops, the residues left behind can potentially pose a health risk. Because usage regulations vary by country, there are even cases where pesticides permitted in Japan are restricted overseas. Public organizations like the Tokyo Metropolitan Bureau of Social Welfare and Public Health state that these residues are at "a level that does not affect health through normal washing and cooking." Even so, we recommend making mindful choices to reduce this daily accumulation.

How to Cut Down Effectively

  • Wash the surface thoroughly under running water. Research, such as studies published in the Journal of the Brazilian Chemical Society, reports that washing with baking soda is effective at removing certain pesticides. When we tried it ourselves, we also felt it washed things off much more easily than just using water alone.
  • Make sure to peel fruits where residue tends to linger on the skin (like apples and tomatoes), and remove the outer leaves of your leafy greens.
  • I refer to the EWG (Environmental Working Group)'s "Dirty Dozen" (produce with high pesticide residue) and "Clean Fifteen" (produce with low pesticide residue) as a helpful guide when making choices at the grocery store.
  • Whenever possible, choosing organic or domestically grown seasonal produce can sometimes mean fewer pesticides are used.

Plastics (Phthalates, BPA, etc.) — Be Careful with Heating and Long-Term Storage

Why is this a problem?

Phthalates and bisphenol A (BPA) have been flagged as endocrine disruptors, meaning they can potentially impact our reproductive health and hormone balance. Sources like Harvard Health Publishing also highlight the risk of these chemicals leaching from plastics into our food.

Everyday steps you can take

  • Avoid microwaving your food in plastic containers (especially those that are old or worn out).
  • Choose glass or stainless steel for your storage containers. We made the switch to glass containers ourselves, and it has really reduced our worries about lingering odors and wear and tear.
  • Even if a product is labeled "BPA-free," other alternative chemicals may still be used, so it's important to be mindful of how we use these items to reduce our exposure.
  • Paying close attention to the ingredients in our cosmetics and hair care products, and choosing to avoid fragrances and anything labeled as "phthalates," is also an effective step we can take.

PM2.5 and Air Pollution — Reducing Exposure Outdoors and Through Indoor Management

Impact on Health

PM2.5 is a fine particulate matter known to take a toll not only on our lungs, but also on our cardiovascular system. Its primary sources are combustion (such as fossil fuels, open burning, factories, and vehicles) and fires.

Remedies

  • On days with poor air quality, try to avoid going outside, or wear an N95 or KN95-equivalent mask.
  • Use an air purifier with a HEPA filter indoors, and try to ventilate your home during times of the day when the outside air is relatively clean.
  • When exercising outdoors, be sure to check the wind direction and traffic conditions. We also make it a point to carefully choose the time of day when running in the city.

Conclusion

While it is difficult to completely eliminate invisible health risks, making small, consistent efforts to reduce them in our daily lives can significantly lighten the long-term burden on our bodies. Keeping your distance from EMFs, washing, peeling, and carefully selecting produce to avoid pesticides, rethinking how you heat and store food in plastics, and using masks and air purifiers to block out PM2.5—these are all steps you can start taking today. These small habits that we've personally adopted and felt the benefits of really do add up to make a big difference. Try incorporating them into your life one step at a time, starting with whatever feels most doable for you.
