Cooling Sheets for Postpartum Night Sweats (and the Years After): A Real Guide
By Rebecca Schwartz Smith, Founder & CEO of Mamala Organics
I'm Rebecca. I built Mamala Organics, a nutrition brand for women in hormonal transition. Our real-food Support Snacks™ are formulated for every stage, from menstruation to menopause, when your body is asking for functional whole foods and you often don't have the time to get them in.
I've had two kids. I have a lot of friends in perimenopause. And I've been through the postpartum night sweat phase twice. (The kind where you wake up in the middle of the night convinced your bedroom is a sauna and your partner somehow isn't even warm.)
When the team at ettitude asked me to write a cooling guide, I had a lot to say.
And honestly, I'm writing this for two versions of myself. The postpartum one who was drenched at 2AM with a newborn on her chest. And the future one I'm already thinking about, because I'm at the age where my friends are starting to talk about hot flashes, and I'm paying close attention. This guide is for both of us.
Here's what I've learned: there's no single fix. But there is a setup that actually helps.
Why Your Body Does This
Postpartum night sweats are not a sign that something's wrong. They're your body doing exactly what it's supposed to do (ugh). During pregnancy, estrogen and progesterone surge, then, within days of birth, they crash. That hormonal drop triggers your hypothalamus, your internal thermostat, to misread your body temperature and overcorrect by sweating. If you're breastfeeding, prolactin suppresses estrogen even further, which is why night sweats can stretch for weeks or months postpartum.
Most women assume it's just part of the deal and don't mention it to their provider. It is part of the deal. It's also miserable. Both things are true.
The perimenopausal version works similarly — estrogen drops, the hypothalamus misfires, the sweating begins. Different chapter, same mechanism. Which is why the setup that got me through postpartum is the same one I'm building for what comes next.
The Foundation
ettitude Cooling Sheets—
Non-negotiable. I was already an ettitude customer before this collaboration, which is the only reason I said yes to writing this. Bamboo lyocell regulates temperature in a way that regular cotton just doesn't — it wicks and releases where cotton absorbs and holds. If you're waking up soaked, your sheets are either helping or making it worse. These help.
Washable Pee Pad—
OK, might sound crazy but when you're soaking through the sheets this prevents the need to also wash your mattress cover on repeat. And in a few years, when you're potty training a toddler, it'll come in handy again. We're all about sustainability here.
The Toolkit
Cozy Ice Pack
Ice on the back of the neck is the tried and true cooldown method and this ice pack is made for just that. If you opt for a bedside mini freezer, even better.
Mini Bedside Fan
Small. Quiet. Pointed directly at your face. Essential. I even travel with this little guy.
Magnesium Spray
Magnesium supports muscle relaxation and sleep quality, both relevant when your body is in hormonal flux. Apply before bed to the soles of your feet.
The Mist
A cooling facial mist on your nightstand is a critical element of my cooldown — a bit of freshness to soothe me back to slumber. My pick is super clean: True Botanicals. But it's also very simple to make yourself — distilled water plus rose petals, cucumber, or aloe, depending on your preference, in a spray bottle, chilled. Voila.
What I Actually Eat Before Bed
This is where Mamala comes in. Night sweats and hot flashes both increase fluid loss and interrupt rest. Mamamellow, our evening Support Snack™, is made with hydrating whole-food ingredients, plant-based protein, and functional mushrooms to support relaxation, replenishment, and rest. Not a cure. But real-food support during the transitions that disrupt sleep.
The Questions I Get Asked Most — I'm not a Dr. but I know a lot of them!
How long do postpartum night sweats last? For most women, two to six weeks. If you're breastfeeding, they can stretch to three months or longer because nursing keeps estrogen suppressed. Once you wean or reduce night feeds, most women notice improvement within a few weeks. That being said, postpartum stretches way beyond the fourth trimester — it's dependent on the individual.
Why does my partner sleep fine while I'm drenched? Because this has nothing to do with room temperature and everything to do with hormones. Your hypothalamus is misfiring, not your thermostat. That's also why blasting the AC doesn't fully solve it. You need to manage heat at the layer closest to your body: sheets, sleepwear, and how you cool down when you wake up.
Does bamboo actually help with night sweats, or is that marketing? I was skeptical too. The difference is real. Bamboo lyocell has a moisture-wicking structure at the fiber level that moves sweat away from your body faster than cotton (17% faster to be exact). When you're producing that much heat, what your sheets are made of genuinely matters.
What should I wear to bed during postpartum night sweats? As little as feels comfortable. Loose, lightweight, breathable. The goal is minimal fabric between your skin and what you're sleeping on. I wear the Eterne set — light enough that it almost doesn't feel like anything, plus it's incredibly chic so if I'm having one of those around-the-house days, I feel better about it entirely.
Will night sweats come back during perimenopause? It certainly is likely, and earlier than most women expect. Hot flashes and night sweats affect the majority of women during perimenopause, which can begin in your late 30s or early 40s. The setup that got me through postpartum is the same one I'm building now. That's why I wrote this for both versions of myself.
The honest version: no product eliminates hormonal sweats entirely. But the right setup means you wake up less, recover faster, and get back to sleep. That's the goal.
Nosh well and stay cool.
