Transcript Kia ora and hello, welcome to the Living Midlife Well podcast. I’m Janine Lattimore, a wellbeing writer and coach here to help people in midlife get off the treadmill of stress and exhaustion, rediscover their joy, and create a life that is aligned with who they really are and what they really want. Today we are diving into a topic that I think is one of the most important — and most overlooked — conversations in midlife health. We’re talking about stress and hormones, and specifically, the hidden role that chronic stress plays in making your midlife hormone experience so much harder than it needs to be. If you have ever felt like you’re doing everything right and still feeling terrible, or you’ve had tests come back clear but you know something is wrong, then this episode is for you. Stay with me — because by the end of this conversation, a lot of things are going to start making sense. When we start talking about hormones in midlife, most people think of women experiencing issues — but men, stay with me, because you experience hormone issues in midlife too. Just like the teenage years, midlife is a time of significant reproductive hormone shift for both male and female bodies. And as if dealing with this transition in your forties and fifties isn’t enough, stress frequently plays a big role in driving even more hormone havoc. The result: fatigue that won’t lift, belly fat that won’t shift, brain fog, mood swings, and disturbed sleep that doesn’t restore you. These aren’t just signs of getting older. They’re signs of a hormone system under stress — and once you understand how those two things are connected, you can begin to do something about it. So let’s start at the beginning and clarify the hormone transitions happening in your body during midlife — for both male and female bodies. In midlife, female bodies transition into perimenopause and then menopause. This transition can start as early as a person’s mid-thirties or as late as their mid-fifties, but the majority of women go through the transition from their late forties to early fifties. Essentially, it is the process of the female body ceasing to produce eggs for reproduction. It is commonly known that during this time, the female body begins to produce less estrogen and progesterone, the two key female hormones. What is less well known, is that as the ovaries gradually produce less estrogen and progesterone, the adrenal glands help compensate by producing precursor building blocks that the body then converts into a weaker form of estrogen. This is very important in the link between hormones and stress — which I will get to shortly. And now for the men. The chief male hormone is testosterone. In a male body, testosterone is at its highest level during adolescence and early adulthood. It starts to decline from about age thirty. For some men, the decline is gradual and changes aren’t very noticeable. For others, the decline accelerates in their forties and fifties and the shift is more dramatic. Many of the symptoms of male midlife hormone shifts are similar to females, such as fatigue and low energy; mood swings or depression — low testosterone can lead to changes in mood, making you more irritable, anxious, or prone to depression and what’s sometimes called “irritable male syndrome”. It can also cause brain fog, forgetfulness, and concentration issues — low levels of testosterone can affect the brain’s executive function and things like decision-making, focus, and memory. Declining levels of testosterone also causes loss of muscle mass and strength — lifting weights feels harder, and gains are harder to maintain; It also leads to weight gain, particularly around the midsection; and low libido and sexual dysfunction. Many of these symptoms are chalked up to being just general aging, but are actually connected to hormonal shifts or imbalances. The issues involved in a “midlife crisis” are likely to be physiological as well as psychological. Experiencing these symptoms is not “just part of aging” and is not inevitable. People in traditional cultures do not experience these symptoms of hormone change at midlife to the degree that most people in industrial cities do — so what is the difference? There are three main ones: a whole food versus a processed food diet, active versus sedentary lifestyles, and levels of stress. One of the key things that impacts our hormonal health is the level of stress we manage almost every moment of the day. Which brings me to the heart of today’s episode. How exactly does stress impact your hormones in midlife? And why does it matter so much more in your forties and fifties than it did before? Stress affects hormones in midlife more than most people realise, and more than most doctors discuss. During the hormonal transitions of your forties and fifties, chronic stress doesn’t just pile on top of what you’re already dealing with. It actively depletes the raw materials your body uses to make sex hormones, suppresses the signals that trigger their production, and makes your body far less able to regulate its own stress response. The result is a feedback loop where midlife hormone shifts make you more sensitive to stress, and stress makes your hormone symptoms worse. If you’re navigating midlife and wondering why everything feels harder than it should, this is a big part of why. During midlife, there is a natural decline in estrogen and progesterone in female bodies and testosterone in male bodies, which can cause a number of challenging physical symptoms. Stress lowers levels of these hormones even further and makes these symptoms worse. For women, the adrenal glands — which take over producing the building blocks for estrogen — are also responsible for producing cortisol, your primary stress hormone. If your body is dealing with chronic stress, the adrenals may prioritize making cortisol at the expense of sex hormone precursors, which can worsen perimenopausal and menopausal symptoms. Over and above this, stress has a more direct impact on one of the most common symptoms of menopause transition: hot flushes. Psychological stress causes the body to release norepinephrine, which narrows the thermoneutral zone — that’s the body’s comfort temperature range. As a result of this narrowing, even minor increases in core body temperature cause the brain to trigger a hot flash. For men, there are three issues. Firstly, both cortisol and testosterone require the same precursor — cholesterol — to be produced. During prolonged stress, your body prioritizes immediate survival and produces cortisol at the expense of testosterone. Secondly, elevated cortisol blocks testosterone from properly binding to target cells and tissue receptors, limiting its effect in the body. Thirdly, chronic stress and systemic inflammation can upregulate the enzyme aromatase, which accelerates the conversion of testosterone into estrogen and causes further hormone imbalance. Now I want to get really specific, because stress doesn’t just affect your hormones in one general way — it disrupts them through several distinct biological pathways. Here are Seven Ways Chronic Stress Hijacks Your Hormones in Midlife Number one. Stress depletes your body’s resources to make sex hormones. Sustained stress keeps cortisol elevated, which redirects the raw material your body uses to make estrogen, progesterone, testosterone, and thyroid hormones — toward cortisol production instead. Number two. Stress reduces your body’s signalling to produce sex hormones. Elevated cortisol suppresses gonadotropin-releasing hormone which reduces the signals for estrogen and progesterone production. Number three. Stress interferes with thyroid hormone production. Elevated cortisol interferes with the conversion of T4 — the inactive thyroid hormone — to T3, which is the active form. It also increases reverse T3, which blocks T3 from doing its job. This is why people under chronic stress often develop symptoms that look like hypothyroidism such as fatigue, cold hands and feet, hair loss, and weight gain even when standard thyroid labs come back normal. Number four. Stress promotes food cravings and belly fat. Cortisol raises blood sugar, and chronic elevation can promote insulin resistance — which is a precursor to diabetes and metabolic syndrome. Abdominal fat gain, changes in appetite hormones, and excessive blood sugar highs and lows are all exacerbated by chronic stress. Number five. Stress promotes mood swings and brain fog. Cortisol influences neurotransmitters such as serotonin, dopamine, and GABA which are chemicals that regulate your mood and cognition. Number six. Stress increases loss in bone density. Estrogen plays a vital role in bone remodelling, and as estrogen levels drop, the breakdown and reabsorption of bone outpaces bone formation. Testosterone is also a critical hormone for bone health in both male and female bodies. It stimulates bone-building cells and maintains bone mineral density. In male bodies, a significant portion of testosterone converts into estrogen, which is essential for preserving bone structure. In both male and female bodies, sustained high cortisol inhibits the cells that create new bone, accelerates bone breakdown, and reduces calcium absorption. And number seven. Stress makes you more sensitive to pain and muscle soreness. Chronically elevated cortisol sensitizes the nervous system. It lowers your pain threshold, prolongs physical recovery, and causes muscles to chronically tighten — increasing the risk of spasms, and it can be connected to restless leg syndrome. Now here is the part that I really want you to hear — because this is where it gets both more complex
