Have you ever been stuck in a relationship that just isn’t working? It’s an endless loop of dysfunction: one of you gets frustrated, the other responds with frustration, and on it goes. That’s exactly how I describe the relationship between sleep and hormonal balance to clients. Just like in that relationship fraught with misunderstanding, the cycle is exhausting and frustrating. And if you don’t take the time to examine what’s really going on, there’s no hope of fixing the problem.
Sleep and Hormones: “It’s Complicated”
The relationship between sleep and hormones is complex and often confusing. Your body is full of hormones carrying messages — and they are all connected to one another. That means if levels of one aren’t optimal, it may skew others.
Several of these chemical messengers are impacted by how much sleep you get; too little sleep can have a big negative effect on hormone levels. At the same time, imbalance hormone levels can directly affect your ability to get to sleep – or stay asleep – at night. See what a quandary that creates?
I have dozens of articles that detail what the various hormones in your body do in my health library. For this article, I’ll focus on those that are most impacted by lack of sleep (while also making sleep elusive).
Sex hormones
When I bring up hormones, many women automatically assume I mean estrogen, progesterone or testosterone. These are the hormones we hear about so often in the media – especially as we draw closer to the typical age of menopause. And they are important to consider when it comes to sleep. If your sex hormones are out of balance, you are very likely to experience a range of symptoms that can make sleeping difficult, such as hot flashes and night sweats.
A dip in progesterone, which promotes sleep, can result in difficulty falling asleep, and if estrogen decreases too much you might be more likely to encounter environmental or other stressors that interrupt sleep patterns. Hormonal shifts in these important hormones can cause depression or mood swings, which also impact sleep.
Human growth hormone (HGH)
Sleep is when your body naturally restores and repairs itself. HGH, which stimulates cell reproduction and regeneration, is released into your bloodstream while you sleep. HGH helps maintain healthy body tissue, promotes healthy metabolism, enhances physical performance, and could help you live longer. Released in pulses, HGH is produced by your pituitary gland.
Research shows that much of the HGH your body produces is released during sleep. A healthy person typically sees most release occur during the first part of deep sleep. Deep sleep, also known as slow wave sleep, is the most restorative sleep; If you don’t get enough your body will constantly be fighting to recover from everyday stresses of life. Typically, you cycle through the stages of sleep four to five times per night, and HGH is released the first few times you enter the deep sleep phase. If you are suffering from sleep disturbances, this can impact your sleep cycles, as well as how much HGH is released.
Cortisol and adrenaline
Cortisol and adrenaline are released in response to stress of any kind – and in today’s busy world, stress is almost constant. When your body is continually calling for more cortisol, it can’t keep up with production of other crucial hormones. And when you’re on high alert (and who isn’t these days?), sleep is usually the last thing on your mind. After all, you wouldn’t lay down for a nap if you were being chased by a tiger. The problem is, your body can’t tell the difference between real danger and other types of stress (like those worried thoughts). Adrenaline sets your heart racing and gives your body a surge of energy, making settling into sleep near impossible at times. Cortisol levels are tied to your natural circadian rhythm – with higher levels during the day and lower at night. When the cycle is disrupted or upside down, sleep problems can result.
Ghrelin and Leptin
These two hormones are directly related to your appetite. Ghrelin stimulates your appetite, making you feel more hungry, and leptin suppresses appetite, signaling to your body that you are full. Lack of sleep has been linked to both a decrease in leptin and an increase in ghrelin. That’s a double whammy to your appetite — and after too many sleepless nights you might find yourself seeking out extra snacks in response to the signals your brain is receiving. And here’s the big issue with that: these cravings are for carbohydrates and sugar, which can send your hormone levels into a tailspin.
Melatonin
This hormone is an essential part of our natural body clock. Melatonin is released with the reduction of light to tell our body it’s time for bed. But with the modern ability to artificially light things up around the clock, our bodies can become confused and hinder release of melatonin. Often I hear about people taking artificial melatonin to help them sleep, which can certainly help, but I advise that you do so under the guidance of your health care practitioner. If you take the wrong amount, or your timing is off, you can actually exacerbate, rather than solve, your problem.
Breaking free from an endless loop
Addressing hormonal imbalance and sleep issues is a lot like being stuck in a traffic circle — if you just keep going around, you’ll never get anywhere. To stop going in circles, you have to take an exit. The same is true with sleep and hormones. You can go around and around, stuck in a loop of hormonal imbalance and sleepless nights, unless you “take the exit” and find steps to address both lack of sleep and hormone levels.
You know that it’s hard to sleep when your hormones are imbalanced, and you know it’s hard to regain balance when you aren’t sleeping. So how do you find the exit? Let me be the GPS that guides you.
Balance hormones naturally
For more depth, check out the articles in my health library about balancing hormones naturally. To get you started, here are a few of my top tips:
- Pay attention to the nutrients you receive, including eating plenty of healthy fats
- Reduce consumption of processed foods, sugar and carbohydrates.
- Use adaptogen herbs to promote hormonal balance.
- Reduce stress and tension whenever possible.
- Don’t ignore emotional issues that may be present – some from very long ago.
- Avoid environmental toxins and endocrine disruptors.
- Try targeted supplements if you need additional support.
Seek restful sleep
I have also offered information about dealing with insomnia in previous newsletters and articles on my site. The first, most crucial step to addressing trouble sleeping is making sure your hormones are balanced.
Other key factors in avoiding sleep deprivation include:
- Establish a set night time routine.
- Unplug from electronics at least an hour before bed
- Create a comfortable sleep haven in your bedroom.
- Avoid large meals before sleep; try to eat your last meal 3 hours prior to sleeping.
- Natural sleep aids can go a long way towards avoiding frustration around sleep.
With a little information about the connections between sleep and hormonal balance, and attention to the tips that can help you create better sleep and natural balance, you can end the dysfunctional relationship once and for all. The freedom you’ll feel is so worth it!
Sleep and hormones are intimately linked – balance both to feel your best!
With some understanding of the connection between sleep and hormones, you can make some adjustments. Just as both parties in a relationship can impact the health of the relationship, both sleep and hormones can have a huge effect on your overall health. And you can’t fix problems with one without also addressing the other. Take time to slow down, boost hormonal health, and start sleeping better. When you do, you’ll wake up refreshed and ready to take on the world!
