Menopause and perimenopause come with a host of changes—physical, emotional, and hormonal. As your body adjusts, your clothing choices, especially your undergarments, matter more than ever. If you’re waking up in a sweat, experiencing sudden hot flashes, or dealing with unpredictable temperature shifts, you’re not alone. That’s why we’ve partnered with the perimenopause and menopause specialists at Midi Health to explain why breathable underwear and breathable bras are more than just a comfort upgrade—they’re essential for your everyday wellbeing.
During perimenopause and menopause, hormonal fluctuations—especially drops in estrogen—can cause symptoms like hot flashes, night sweats, and skin sensitivity. These shifts can make your go-to bras and undies feel uncomfortably hot or clingy, especially if they trap moisture or lack airflow.
Our trusted friends and experts at Midi Health explained that about 75% of women experience vasomotor symptoms during the menopause transition, which includes hot flashes, night sweats, and palpitations. “Hot flashes can go on for years and take a toll on a woman’s health and well-being,” explains Dr. JoAnn Manson, professor of women’s health at Harvard Medical School and professor of epidemiology at Harvard School of Public Health.
The body’s natural system for maintaining a stable internal temp is called thermoregulation, and during menopause, this system can become unpredictable. According to experts at Midi Health, “Hot flashes occur when the brain’s thermoregulatory center (the hypothalamus, which controls heat production and loss), struggles to do its work. As estrogen levels change, the hypothalamus becomes more sensitive to slight changes in body temperature. Thrown off by hormone fluctuation, the brain thinks the body is too warm and triggers a series of mechanisms meant to bring down temperature, including expanding blood vessels near the skin’s surface, increasing blood flow and heart rate, and activating sweat glands. So, essentially, a hot flash is your body doing a great job of cooling you off when you’re not actually overheated.”
While frequency and severity of hot flashes decreases with age, Midi Health provides an arsenal of effective treatments that can help. One simple example is lifestyle changes, which Midi Health describes as avoiding triggers such as dietary choices that make things worse such as alcohol, caffeine, and spicy food.
Another obvious lifestyle change is staying away from tight, non-breathable clothing. This is where breathable underwear and lightweight bras make all the difference. The right fabric can cool you down and help reduce irritation throughout the day and night, regardless of how long this particular symptom impacts your life.
So–what is breathable underwear and what is it made of? Breathable undergarments are made with fabrics that promote airflow, absorb sweat, and dry quickly. Traditional materials like cotton and modal are already well-known for their moisture-wicking and breathable properties.
But Thirdlove’s TempSync™ Collection takes innovation further with cooling bras and underwear for menopause powered by 37.5® Technology.
The TempSync™ Collection is Thirdlove’s answer to the real needs of women experiencing menopause and perimenopause. Powered by 37.5® Technology, it’s the first-ever line of cooling bras for menopause and breathable underwear that actively combats hot flashes and chills. While this tech has been seen in men’s apparel for years, Thirdlove is the first to ever make it available in intimates.
This groundbreaking fabric uses active particles derived from volcanic minerals to respond dynamically to your body’s temperature. It speeds up the evaporation of sweat next to the skin and helps delay overheating—keeping you in your ideal comfort zone longer. Unlike wicking materials that simply distribute moisture, the temperature regulating fabrics and materials with 37.5® Technology actually remove it.
This smart fabric is also soft, stretchy, and lightweight. The bras in Thirdlove’s TempSync™ collection feature perforated fabric and breathable foam to enhance airflow. It’s the first time ever that this kind of temperature-regulating technology has been available in intimates—and it’s specifically designed for women navigating hormonal changes.
Whether you’re heading to work, running errands, or winding down for bed, this collection offers support, softness, and cooling comfort all day (and night) long. Designed with breathable, mineral-infused fabrics, our TempSync™ collection intelligently balances body heat and keeps you dry—even before you start sweating.
When your body is going through constant changes, comfort, confidence, and proper support become non-negotiable. Thirdlove’s bras and underwear are thoughtfully designed to meet the unique needs of women navigating this life stage—without compromising on fit or function.
Our bras and underwear are designed with your body’s comfort in mind—featuring soft fabrics, flexible support, and a tagless, irritation-free design. We offer both breathable cotton bras and innovative TempSync™ temperature regulating styles for all-day ease.
