Our Philosophy
Why we focus exclusively on nutrition, exercise and sleep
These aren't random choices. They're the three lifestyle factors with the strongest evidence for improving hormonal health, and the three things entirely within your control.
You can't control your hormones directly, but you can control the inputs that shape them.
The Core Belief
Behind everything we do at HerRhythm
Why I Built This
When I lost my period in 2023, my GP told me there was nothing I could do. Just wait and hope. That felt deeply wrong, so I went looking for answers.
Two years later, with a Master's in Health Psychology from King's College London specialising in women's health, I can tell you: that advice was incomplete.
The research is clear. While we can't directly manipulate our oestrogen, progesterone or insulin levels, we absolutely can influence the lifestyle factors that shape how our bodies produce and respond to these hormones.
The Three Pillars
What the research tells us about the lifestyle factors that matter most for hormonal health
Nutrition
What you eat directly shapes your hormonal environment
Exercise
Movement that works with your cycle, not against it
Sleep
The often-overlooked foundation of hormonal balance
Why These Three?
The "lifestyle medicine triad" isn't a marketing term. It's what the science consistently points to.
They're Modifiable
Unlike genetics or age, you can change what you eat, how you move, and how you sleep starting today. Health psychology research shows that interventions people can control themselves lead to better adherence and sustainable outcomes.
They're Interconnected
Poor sleep makes you crave sugar. Poor nutrition saps your energy for exercise. Lack of exercise disrupts sleep quality. These three form a feedback loop, and improving one naturally supports the others.
They Have the Strongest Evidence
A 2018 meta-analysis in The Lancet Global Health found these three factors contribute to more preventable health issues than any other modifiable factors. The American College of Lifestyle Medicine identifies them as core pillars.
They Change Throughout Your Cycle
Generic advice ignores that your body has different needs on day 3 versus day 18. Iron needs peak during menstruation. Exercise tolerance varies with oestrogen. Sleep requirements shift in the luteal phase.
What We Don't Do
Staying focused means saying no to things that don't serve you
Sell Supplements
We recommend magnesium if research supports it, not because we profit. No affiliate links, no product partnerships.
Give Medical Advice
HerRhythm is educational, not medical. We help you understand research for informed conversations with your healthcare provider.
Overpromise Results
We show what the evidence says, including when it's limited or mixed. Evidence quality ratings help you know what's well-established.
Built on Health Psychology
HerRhythm isn't just a collection of tips. It's built on principles from my Master's in Health Psychology at King's College London, specialising in women's health.
Health psychology teaches us that sustainable behaviour change comes from understanding, not just instruction. When you know why iron absorption matters during menstruation, you're more likely to actually pair your spinach with vitamin C.
That's why every HerRhythm recommendation comes with an explanation. We're not just telling you what to do; we're helping you understand your body so you can make informed choices that actually stick.
