Every day I get emails from women who are thinking about joining me on the MyMT programmes [Circuit-Breaker’ for thinner women and ‘Transform Me’ for women who want to lose weight], because they feel over-whelmed with night sweats and hot flushes. Women in their 40’s right through to their 60’s. I am astounded by how many are on HRT or Bio-identical hormones …. the same medical interventions that are supposed to help them reduce their hot flushes and night sweats. Clearly, these interventions are not working for them and because I had this experience too, I now better understand why.
When my own hot flushes and night sweats were frustrating me, I was on HRT (Menopause Hormone Replacement Therapy) too. They seemed to get worse in the evening making me vent my frustration to the family, with the lone, desperate cry of the menopausal woman – “Is it hot in here, or is it just me?” Their response was always, “It’s just you Mum!”
At the time I was 50 years old – bang on the average age that our ovaries begin to lose oestrogen-making cells and our oestrogen production starts to drop – and wondering why on earth my body was over-heating, why my energy levels were plummeting, why my sleep was filled with night sweats, why I was putting on weight, why my joints were sore, why dark clouds were filling my normally upbeat moods and why oh why, were the lovely HRT tablets not doing their job.
When nobody else had the answers I sought and the endless supplements I bought for menopause were not working I decided to put on my ‘physiology-hat’ and really get to the bottom of understanding what was going on when we can’t beat the heat. Most importantly, I was desperate to discover what was going on in a body that was not coping with the ‘change of life’. I’m so pleased that I did.
If you’re feeling like this too, then take a couple of minutes to read what I have to say … because I know that many of you are just like I was at the time – coping with work, busy-days, family matters on the home-front, exercising when you can and trying to cope with a body that’s taking it’s own course as you go into or through menopause. You feel a bit stressed. So, to start with, I have a question for you:
Did you know that when you are experiencing hot flushes and/or night sweats, this is a sign that your body is under dis-stress and trying to cool down?
As I began to unravel the physiology of hot flushes, it wasn’t too long before I realised that because our temperature regulation is under the control of our hormonal system, then when oestrogen lowers in peri-menopause, temperature-regulating hormones in the pituitary region of the brain and our thyroid are affected too.
You see, what’s missing from the conversations about menopause symptoms, are that all hormones in the body ‘talk’ to each other in order to keep you functioning. When oestrogen and progesterone produciton decline, our thyroid, pituitary and adrenal hormones are affected too.
Can you see from this image that our pituitary and thyroid glands are connected? The powerful hormones secreted by these glands also send messages to our adrenal glands and ovaries too.
Hormones all work together to keep our body functioning. They are chemical messengers which control all sorts of functions in the body, from heat management, to blood pressure control, to blood sugar regulation to our sleep cycles and feelings of hunger!
That’s why, when our oestrogen production decreases during menopause, this has a flow-on effect on other hormones in your body as well. This includes your heat regulation hormones too.
If you can’t beat the heat, no matter the temperature outside, then please have a read of my ‘top-10’ factors that increase your hot flushes:
It’s not just about reducing sugar and processed food as we age. In menopause, my emphasis is on reducing protein as well. Yes, I know that this goes against what you may have heard, but the amount and timing of your protein intake is crucial. Protein is ‘thermo-genic’ which means ‘heat-generating’. I learnt that years ago in the fitness industry and when I was trying to understand why my hot flushes were so bad, I remembered that high protein diets cause too much stress on the thyroid, liver, kidneys and gut. The result? Lots of sweat as your body tries to cool down.
and this isn’t just emotional, but is also related to the physical stress on your cells and tissues. For decades, our cells and tissues have been accumulating inflammatory changes, especially if you have been doing a lot of high intensity exercise for decades. When you reach menopause and your blood vessels become more constricted with the loss of oestrogen and you aren’t sleeping which is when you recover overnight, then all of this inflammation sitting deep in your tissues (especially in your muscles, gut, bowel and liver) keeps your chronic stress hormone, called cortisol, higher than normal. When cortisol stays around all day, then your thyroid hormones overwork too. An unhappy thyroid combined with menopause hormonal changes causes your temperature and blood pressure to increase, which then has you wiping your brow with excess sweat as your body tries to get rid of the heat.
Moderation is everything and during menopause, both too much and too little exercise can cause more hot flushes. If you aren’t sleeping but you are doing lots of heavy, high-intensity exercise most days or you work in a physically-demanding job such as nursing, then your body doesn’t recover overnight. This means that your chronic stress hormone called cortisol stays elevated. As I explained earlier, then this causes your blood pressure and heart rate to stay higher than normal and you sweat more. The same can also be said of women who are mainly sedentary. If you aren’t doing some activity, then there is a risk that you aren’t boosting your cells and tissues with oxygen. This can lead to fatty liver, poor cardiac health and more hot flushes.
When our heart rate and blood pressure is higher than normal, this increases heat production in the body. Part of the reason for this, is because as we transition through menopause and we are ageing, our blood vessels become more constricted. Not only are they ageing, but we are losing muscle density as well. What this means is that our muscles (and our sweat glands) change when we lose oestrogen, so our ability to regulate heat and sweating changes too.
New genetic research shows that we all have DNA that are receptive to living in either hot or cooler climates. If we are out of sync with the genetically-set DNA, then in menopause, this can cause more discomfort and hot flushes. I have women on my programme from Alice Springs in Australia – as one of the hottest places on the continent, I am so thankful that they have come on board. One of the problems with living in such a hot climate is that we tend to live inside in air-conditioning and this changes our Vitamin D absorption which can dive-down in menopause. Vitamin D is a hormone and because our skin is the largest organ in the body and has numerous oestrogen receptors in it, menopause affects our Vitamin D absorption too. When levels are low, then hot flushes become worse and so too, does calcium absorption, so it’s important that women get their Vitamin D levels checked – even more so when it’s so hot outside that it’s cooler to live inside.
I think many of you would have already discovered that it’s a catch-22 between not sleeping and night sweats – on one hand the night sweats wake you up, but on the other hand, when you can’t stay asleep, your hot flushes, night sweats and feelings of anxiety become worse. Yes? Well, there is a reason for this. When we aren’t sleeping, we aren’t recovering and restoring our immune system overnight. We also aren’t fat-burning or recovering from our day-to-day activities. What then happens, is that our adrenal glands make more cortisol. To do this, they use our lovely calming progesterone, which is also why women in menopause experience more anxiety as well – and it’s also why in both of the MyMT 12 week programmes, the first module you listen to, is how to sleep all night. It’s that important.
All of these powerful nutrients are needed to restore hormonal health as you transition through menopause. For example, the beautiful trace mineral called iodine, is a vital component of hormones produced by the thyroid gland that are responsible for a number of important functions in your body. This includes metabolism, nerve and muscle function, regulation of body temperature and blood cell production. If you don’t get enough iodine-rich foods, your hot flushes can become worse. This is why I have a nutritional programme in the MyMT programmes, that is rich in iodine and all the other nutrients that we need during menopause and into the years beyond. My nutritional information comes out of women’s healthy ageing research.
Leaky gut affects the entire body and whilst I do recommend seeing a suitable health practitioner in case you have certain medical concerns, so many women have developed leaky-gut (as I did too), that I have researched what to do to turn this around. If this is you, then the continual presence of inflammation in your gut and bowel increases heat in the body too. When heat and inflammation remain high, then this leads to poor sleep which sets off night sweats.
When we go into peri-menopause, it’s a little bit like puberty and pregnancy – our hormones are changing and our body is trying to adjust. It took me hours and hours of research to figure out how to reduce our symptoms in menopause and allow our body to adapt to this changing hormonal environment, whilst still living the life we love to live. Re-adjusting our hormones to match our biological ageing is key and it’s why, if we keep doing the same old things that we have done in the past, then often we are fighting against this new hormonal environment.
When my own hot flushes were troubling me DAY and NIGHT, I knew I had to get to the bottom of the science of them. Today, hot flushes no longer control me or define me. This is the same for many of the women who are following the strategies I have researched and you can read their Success Stories here.
I don’t want you to still be experiencing hot flushes in your post-menopause years and if you are on HRT, then research suggests that 5 years is long enough. So, if you are not coping with your heat regulation, sleep, anxiety, weight or joint problems, then will you join me? No matter where you live in the world, you can come on board.
All you do is purchase on any sales page on the My Menopause Transformation website. Whichever programme you choose [Circuit-Breaker for thinner women or Transform Me for women who want to lose weight] then there are 3 monthly payments of $99NZ. This includes my private coaching as well. If hot flushes and night sweats are getting you down, I hope you can join me and the hundreds of women already on the programme.
