Too Much Time Indoors Is Hazardous to Your Health



Snuggling inside a comfy blanket on the sofa with a warm drink on a blustery chilly day sounds wonderful. But as temperatures drop and daylight hours diminish, resist the urge to enter a state of hibernation. Remember that it's still important to get outside!

That's because humans aren't designed to spend the entire day inside. We need to spend time outside to stay healthy and happy. Sunlight (especially in the morning) improves mood and regulates circadian rhythms. Being outside promotes good vision by protecting against myopia. Plus, the air is cleaner! According to the EPA, "a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities."


Make Time Every Day to Do the Things You Love

On a walk around 7:30 pm. The kids should have been getting ready for bed, but oh well.

Once upon a time I taught elementary school for many years in Los Angeles. Although working with kids was often rewarding, there was plenty about teaching that I did not enjoy. Some of the required curriculum was decidedly lackluster. Then there was the endless paperwork, the depressing home situations, the demoralizing staff meetings (your test scores still suck!), the discipline issues, the test prep, and the staff politics. Worst of all, I felt like a failure almost every day. In the beginning, I just didn't know what I was doing. And even later when I did, there was simply not enough time in the day to do everything, and certainly never enough time to do it well.

But despite the overwhelming pressures of teaching in low-income under-performing schools (often in danger of being "taken over" by the state), I decided for my own sanity to spend some time each day doing things that I enjoyed and considered important, even if nobody else cared that I did them (or even if my principal and other higher ups actively discouraged me from doing them). I read aloud to my students every day. We exercised every day. And we talked about poetry and sang songs every single day.

Turns out that learning to cope with an incessant sense of failure and always having more to get done than can possibly get done were excellent preparation for being a parent. Now as a parent of three little ones, when the sense of failure becomes especially overwhelming, I remember this lesson from my teaching days: make time every day to do the things that you love.

Use Eco-friendly and PVC-free Yoga Mats to Avoid Phthalates and Other Toxic Chemicals



Once I began exercising again after my third child was born, I decided it was time to retire my decade-old yoga mat and invest in a new one. My old yoga mat was very thin and not very high quality (it came free with a yoga DVD), but still usable. However, after years and years of using it, it dawned on me that it was almost certainly made of vinyl (PVC).

PVC is arguably the most toxic plastic. It's made with toxic chlorine which results in toxic dioxin being released into the environment. PVC products are also made using toxic additives such as lead and endocrine-distrupting phthalates, additives which readily migrate and off-gas during the use of PVC products. I especially wasn't comfortable with exposure to phthalates, which are added to PVC to make it soft and flexible (like a yoga mat), and which readily migrate to the surface of PVC products in which they are found. Phthalates also readily pass from mother to fetus through the placenta and are also found in breastmilk.

Phthalates are endocrine disruptors and have been linked to:
  • lower testosterone levels
  • decreased sperm counts
  • poor sperm quality
  • malformations of the male reproductive tract and testicular cancer
  • obesity
  • reduced female fertility
  • preterm birth and low birthweight
  • a worsening of allergy and asthma symptoms
  • behavior changes

Natural (PVC-free) Yoga Mats


Ten years ago, I'm guessing it was pretty difficult to find a PVC-free yoga mat. But now, thankfully, there are many PVC-free options. I wanted a natural rubber mat, and also a thicker one that would give me some decent cushion on top of my hardwood floor. I ended up purchasing the Gaiam Sol Power-Grip Yoga Mat made of natural rubber (note: I remember that it smelled strongly of rubber initially). It is pretty thick (4 mm) and has a nice grip to it too. I use my mat for beginning yoga but also for general exercise (while barefoot on hardwood) that includes pilates, weights, cardio, and stretching. I do not get super sweaty when I workout and am not terribly concerned about slippage. If you are a serious yogi, see the reviews below by yoga experts.

Some other natural (PVC-free) yoga mats include:


TPE and PER Plastic Yoga Mats


There are also less expensive synthetic yoga mats made from Thermoplastic Elastomer (TPE) and Polymer Environmental Resin (PER). TPE is a synthetic rubber that is touted as a healthy alternative to PVC. According to Thinksport, TPE is "free of BPA, PVC, Lead, Phthalates, Dioxins, and biologically toxic chemicals." What exactly TPE is I couldn't tell you. But I feel confident stating that it is far better than traditional PVC.

Probably the least expensive alternative to traditional PVC is Polymer Environmental Resin (PER), which is touted as a less-toxic form of PVC. According to one manufacturer, which describes PER as "clean PVC," PER is free of "phthalates, dioxins and furans, phenal, or heavy metals and has a ecologically safer method of production which is better for the workers and the environment."

For my daughter, who often likes to "exercise" with me, I got a smaller mat so it wouldn't take up as much room. I purchased the Namaste Kid's Eco-friendly Kids Yoga Mat (made of PER). It measures 24" by 48" and is much thinner than mine, but suitable for my toddler, 4yo or even 6yo. It's main purpose is really to keep them off my mat and out of my way. I actually didn't realize PER is a form of PVC when I bought it. I couldn't find a small-sized rubber yoga mat. In retrospect, I would have preferred a TPE mat such as the Little Yoga Mat for my kids, but I don't feel strongly enough about it to stop using the PER mat.

Pregnancy, Pain, and Prenatal Exercise DVDs



If ever there was a good time to get serious about regularly exercising, it's pregnancy! Exercise during pregnancy decreases your chances of preeclampsia, builds endurance for labor and delivery, and allows for a quicker postpartum recovery. In addition, exercise also helps regulate your blood sugar levels and can be as effective as medication in treating gestational diabetes. For me, exercise was an important way to cope with the discomfort and pain of pregnancy at a time when I wanted to avoid taking pain relief medications.
