Perimenopause Hot Flashes: How to Sleep Better

Key Takeaways:

• The hormonal fluctuations of perimenopause can result in uncomfortable symptoms, including night sweats, that make it hard to sleep.
• Avoiding triggers and tweaking your sleep environment can help keep you cool as your body temperature rises.
• Hatch Sleep Clock helps you create calming routines for better sleep using your own sleep trends.

Waking up sweaty? You’re definitely not alone, especially if you’re going through the perimenopause, the years leading up to your final period. One of the most common symptoms — and one you may already be experiencing — is hot flashes. When these sudden body temperature surges happen at night, they can impact your sleep, creating a frustrating cycle that may worsen your symptoms during the day.

As your hormones and body temperature ebb and flow, there’s a lot you can do to keep your body comfortable — and to protect your sleep. Below, learn more about perimenopausal sleep disturbances, how to sleep with hot flashes, and how Hatch Sleep Clock can help.

Why Do Hot Flashes Disrupt Sleep During Perimenopause?

During perimenopause, fluctuating levels of estrogen can affect the hypothalamus, the area of the brain that helps regulate body temperature. These hormonal shifts shrink your body’s thermoneutral zone, the small temperature range in which you feel comfortable without needing to sweat or shiver. As a result, even a slight rise in core body temperature can trigger a hot flash, causing sudden warmth, flushing, and sweating.

Hot flashes at night, often called night sweats, can interrupt sleep by triggering brief awakenings or making it harder to fall back asleep afterward. Sleep naturally depends on a gradual decline in your core body temperature, so repeated periods of heat and sweating can work against that cooling process. Hot flashes and poor sleep can also feed into each other during perimenopause. The more frequent or intense your hot flashes are, the more likely they are to wake you up throughout the night and make it harder to get restful sleep.

How to Sleep With Hot Flashes

Deep breaths: You may not be able to change what’s happening in your body (if only!), but you can change your surroundings in a way that makes it easier to stay cool throughout the night (and, as a result, get better sleep). Here are a few places to start.

Keep Your Bedroom Cool

Yes, it’s obvious. But it’s also important! Keeping your room temperature as cool as possible can make it easier to withstand the physiological temperature fluctuations that happen at night. If you can, set your bedroom thermostat to 60-67°F. A cooler environment also supports the natural drop in core body temperature that helps signal to your body that it’s time to sleep. If 60–67°F isn’t comfortable or realistic, aim for a temperature that feels comfortably cool to you, and use a fan or open window to increase airflow.

Surprisingly, keeping your room cool doesn’t necessarily mean every part of you needs to be cold. Warming your hands or feet — think your favorite cozy socks rather than a hot bath — may help your body release heat through the skin, supporting the natural drop in core temperature that happens as you fall asleep.

Choose Breathable Bedding and Sleepwear

If you’re waking up covered in sweat, skip the heavy blankets and stick with lightweight, breathable bedding and PJs. Materials like bamboo, linen, and cotton can be especially comforting if you sleep hot. Moisture-wicking fabrics can also help pull sweat away from your skin so you feel cooler and drier when a hot flash hits. Consider layering lighter blankets instead of using one heavy comforter, so you can quickly adjust your bedding without fully waking up. It may also help to keep a clean set of sheets or two on hand if you sweat overnight.

Identify and Avoid Hot Flash Triggers

Certain habits can worsen or trigger hot flashes, so doing your best to avoid them throughout the day (and especially the evening) can go a long way. Common hot flash triggers include spicy food, alcohol, caffeine, and stress. Tight clothing can also hike up your core body temp, so keep your nightwear loose along with breathable.

Hot flash triggers aren’t the same for everyone, so pay attention to patterns in when your symptoms tend to show up. If you notice that a glass of wine or spicy dinner consistently leads to a sweatier night, adjusting the timing or cutting back may help you sleep more comfortably.

Create a Bedside Cooling Kit

You may not be able to prevent every nighttime hot flash, but you can make it easier to recover from one without fully waking yourself up. Keep a few cooling essentials, like a small fan, cooling towel, cold pack, or fresh sleep shirt, within arm’s reach of your bed. That way, you can cool down and get comfortable again without turning on bright lights or wandering around the house, both of which can make it harder to drift back to sleep.

Create a Calming, Consistent Bedtime Routine

With so much change happening in your body during perimenopause, a consistent routine can feel grounding. Plus, keeping a predictable evening routine can make it easier to fall and stay asleep (one less bedtime hurdle to worry about). Hatch Sleep Clock contactlessly tracks your sleep from your bedside table, then suggests personalized routines that fit your life to help you get better sleep.

For example, if it notices you’re tossing and turning more on nights you only unwind for a few minutes, it may suggest you add calming sleep music or a relaxing meditation to your nighttime ritual. When so much feels out of control — during perimenopause and beyond — taking time to calm your mind and body can feel like a much-needed respite from all the ups and downs.

Frequently Asked Questions

Do hot flashes get worse at night?

Hot flashes don’t necessarily become more severe at night, but they may feel more disruptive because they can wake you from sleep. Nighttime hot flashes, often called night sweats, can make it harder to stay asleep and feel rested the next day.

What temperature should you sleep at during perimenopause?

There’s no single ideal bedroom temperature for everyone, but a cool sleep environment can make nighttime hot flashes more manageable. Many sleep experts recommend keeping the bedroom around 60-67°F, then adjusting based on what feels comfortable for you.

How long do perimenopause hot flashes last?

An individual hot flash typically lasts a few minutes, but vasomotor symptoms can continue for several years during the menopause transition. How often they happen and how long they persist varies widely from person to person.
