Step Count Doesn't Matter (And Other Myths We Need to Bust)

Episode Script

Thanks Toni. We've got some serious myth-busting to do today.

I'm looking at three pieces of research that completely flip common assumptions about our health. And honestly, one of them made me rethink my entire relationship with my step counter.

First up - that vitamin D deficiency so many of us deal with after menopause. We've all heard the advice: get outside, take more walks, move your body. All good advice, but researchers just published something in PubMed that changes how we should think about this.

They strapped accelerometers on postmenopausal women - not the kind that just count steps, but the sophisticated ones that track exactly how you move throughout the day. What they found was fascinating. Your total step count? Basically irrelevant to your vitamin D status. But the amount of time you spend sitting? That's what correlated with lower vitamin D levels.

This study was led by Domingo-Molina and published just yesterday. They specifically looked at sedentary behavior versus daily step count in postmenopausal women. The results challenge everything we think we know about exercise and vitamin D.

Now, vitamin D isn't just made when you exercise - it's made when your skin is exposed to sunlight. So this makes sense when you think about it. You could hit 10,000 steps on a treadmill in a dark gym, but if you're spending the rest of your day parked at a desk, you're not getting that sun exposure your body needs.

What this research suggests is that breaking up sitting time might be more important than logging steps. Getting up every hour, stepping outside for a few minutes, working at a standing desk - these things could matter more for your vitamin D than that evening power walk.

I find this oddly liberating. The pressure to hit step goals can be intense, especially when you're dealing with joint pain or fatigue that makes long walks feel impossible. But getting up from your desk every hour? That feels doable.

Speaking of myths we need to bust - The Guardian just published a piece that tackles one of the biggest misconceptions about perimenopause. How many of you have gone to your doctor asking for "the test" to see if you're in perimenopause?

Dr. Keren Landman explains why that blood test you're hoping for probably won't give you the answer you want. Hormone levels fluctuate wildly during perimenopause. You could test normal on Monday and be in full hormonal chaos by Thursday.

The article describes this perfectly - there's a "special frisson" to period changes in your mid-40s. Every missed cycle, every heavier flow, every weird symptom sends you down a mental rabbit hole. Am I or aren't I?

But doctors typically diagnose perimenopause clinically, based on your symptoms and your age, not on blood work. If you're in your mid-40s and your periods are changing, if you're having hot flashes or sleep disruption or mood swings - that's usually enough information.

This doesn't mean blood tests are useless. They can help rule out other conditions or guide treatment decisions. But the idea that there's one simple test that will definitively tell you where you are in the menopause transition? That's a myth that needs to die.

The Guardian piece also points out something important - not every period change in your 40s is perimenopause. Stress, weight changes, thyroid issues, other health conditions can all mess with your cycle. This is why working with a healthcare provider who understands menopause is so important.

Now, the third study I want to talk about connects some dots that I hadn't considered before. Researchers looked at women with a history of primary infertility and found something striking - these women reached menopause about a year earlier than women without fertility struggles.

This was published in the NAMS journal Menopause, and it followed women longitudinally - meaning they tracked the same women over time, which gives us much better data than just taking a snapshot.

Primary infertility means you've been trying to conceive for a year or more without success, and you've never been pregnant before. The researchers found that women with this history had an increased risk of early menopause overall.

This makes biological sense. Both infertility and early menopause can be related to ovarian reserve - essentially how many viable eggs you have. If you have fewer eggs or they're declining more rapidly, that could affect both your ability to conceive and when you reach menopause.

But what strikes me about this research is how it highlights connections in our reproductive health that we don't always talk about. If you struggled with fertility, it might be worth having conversations with your healthcare provider about menopause timing. Not to worry unnecessarily, but to be prepared and informed.

Early menopause - before age 45 - comes with increased health risks, including higher chances of cardiovascular disease and osteoporosis. Knowing you might be at risk gives you time to discuss preventive strategies.

This research also validates something that women who've dealt with infertility often feel but can't quite articulate - that their reproductive system works differently. It's not about blame or fault. It's about understanding your body's patterns so you can make informed decisions about your health.

All three of these studies remind me why I love doing this show. So much of what we think we know about women's health is based on assumptions that don't hold up when you actually study women's bodies carefully.

Your step counter might be tracking the wrong thing. That blood test might not give you the answers you want. And your fertility history might tell you something important about your menopause timeline that nobody thought to mention before.

What other health "facts" do you think we should be questioning?
