Why Can't I Sleep Anymore?

Understanding Sleep in Midlife—and Why Rest May Be the Best Medicine Your Body Needs

One of the most common things I hear from women in midlife is "I just don't sleep like I used to."

Sometimes they fall asleep without much trouble, only to find themselves staring at the ceiling at three o'clock in the morning. Others wake up several times a night feeling warm or restless, while some sleep for what seems like plenty of hours but wake feeling as though they barely slept at all.

If you've found yourself wondering what happened to the effortless sleep you used to enjoy, you're certainly not alone.

Sleep changes as we get older, but I don't believe poor sleep is simply something women should accept as an inevitable part of aging. Like so many of the symptoms we've talked about throughout this series, changes in sleep are often your body's way of asking for a closer look.

One of my favorite questions to ask patients isn't, "How many hours are you sleeping?" Instead, it's, "When did your sleep begin to change?"

That question often opens the door to a much bigger story.

For many women, the answer begins with the hormonal shifts of perimenopause and menopause. As estrogen and progesterone fluctuate and eventually decline, sleep often becomes lighter and more fragmented. Some women are awakened by hot flashes or night sweats. Others don't experience those symptoms at all, yet still find themselves waking repeatedly for reasons they can't quite explain. Progesterone also has calming effects within the brain, so declining levels may contribute to difficulty staying asleep, even in women who have never struggled with sleep before.

But hormones are rarely the entire story.

Midlife is often one of the busiest and most demanding seasons of life. Careers may be at their peak. Children are growing into adults while aging parents begin needing more support. Relationships evolve. Some women are navigating divorce, caring for loved ones, grieving losses, or adjusting to an entirely new chapter of life. Even wonderful changes can bring stress, and our minds don't always know the difference between preparing for tomorrow and trying to fall asleep.

I sometimes tell patients that our brains can become very productive at exactly the wrong time of day.

Sleep is also deeply connected to our overall health. Blood sugar fluctuations, thyroid disorders, chronic pain, anxiety, depression, certain medications, alcohol, and even digestive health can all influence the quality of our sleep. One condition that deserves particular attention is sleep apnea. Many women are surprised to learn that the risk increases after menopause, even in women who don't fit the stereotype of someone with sleep apnea. Waking with headaches, feeling unusually tired during the day, or simply never feeling refreshed after a full night's sleep can all be clues that it's worth looking more closely.

That's one reason I encourage women not to assume that every sleep problem is "just hormones."

As a licensed naturopathic doctor, I like to take a step back and look at the whole picture. I want to understand when your sleep changed, what else changed around that time, how your stress levels have been, what your evenings look like, how much caffeine or alcohol you're consuming, whether your thyroid or blood sugar might be contributing, and whether there are signs that another medical condition deserves attention. Sometimes the answer becomes surprisingly clear once we connect all the pieces together.

One of the things I find fascinating about sleep is how quickly it influences nearly every other aspect of our health. When we don't sleep well, we often feel hungrier the next day, crave more sugary foods, have less motivation to exercise, and find ourselves becoming more impatient, emotional, or forgetful. We may struggle to focus at work or find ourselves reaching for another cup of coffee just to get through the afternoon.

Sleep isn't simply about feeling rested.

It's during sleep that our brains organize memories, our muscles recover from the day, our immune system does much of its repair work, our hormones are regulated, and even our skin begins its nightly renewal. Every night, while we're resting, our bodies are incredibly busy taking care of us. That's why I believe sleep is one of the most overlooked pillars of good health.

The encouraging news is that improving sleep often begins with understanding why it changed in the first place. For one woman, that may mean treating bothersome hot flashes that are disrupting her rest. For another, it may involve identifying previously unrecognized sleep apnea. Someone else may discover that improving blood sugar regulation, addressing thyroid health, reducing evening alcohol, or managing chronic stress dramatically improves the quality of her sleep.

Sometimes lifestyle changes are enough. Sometimes botanical medicine, nutritional support, cognitive behavioral therapy for insomnia, or prescription treatments have an important role. There isn't one right answer because there isn't one reason people struggle with sleep.

I don't believe in one-size-fits-all solutions.

Simple habits can certainly help. Keeping a consistent bedtime, getting outside into morning sunlight, limiting screens before bed, exercising regularly, and creating a cool, comfortable sleeping environment all support healthy sleep. But if you've already been doing those things and you're still waking up exhausted, don't assume you simply have to live with it. Your body may be asking for a deeper conversation.

One of the most rewarding parts of helping women improve their sleep is seeing what happens next. Their energy begins to return. They think more clearly. Their mood improves. They have more patience with the people they love. Exercise feels easier. Food cravings become more manageable. They begin feeling like themselves again.

That's because sleep isn't separate from health. It is health.

If your sleep has changed, don't hesitate to bring it up with your healthcare team. A licensed naturopathic doctor or another qualified healthcare professional can help you understand what may be contributing and develop a plan that's personalized to your needs. You don't have to accept restless nights as your new normal.

You deserve to wake up feeling rested, restored, and excited for the day ahead.

Because while sleep may appear quiet from the outside, it's one of the most extraordinary things your body does for you every single night.
