Best Cooling Products for Hot Flashes During Perimenopause
Find the best cooling products for hot flashes in perimenopause, from cooling pillows and fans to wearable tech and bedding solutions.
Managing Hot Flashes with the Right Products
Hot flashes are the most commonly reported perimenopause symptom, affecting up to 80 percent of women to some degree. They occur when declining estrogen disrupts the hypothalamus, the brain region responsible for temperature regulation, causing it to misread normal body temperature as overheating and trigger a rapid heat-release response. While HRT remains the most effective medical treatment, the right combination of cooling products can dramatically reduce the impact of hot flashes on daily life and sleep quality. The products below cover different situations, from night sweats to flashes at work, so you can build a toolkit that fits your lifestyle.
Cooling Pillow Cases and Pillow Inserts
Night sweats wake many women multiple times a night, and the pillow surface is often the first point of discomfort. Cooling pillowcases made from bamboo, Tencel, or phase-change materials absorb and dissipate body heat more effectively than cotton or synthetic fibres. Phase-change cooling technology, originally developed for NASA, contains materials that absorb heat as they change from solid to liquid state at body temperature, then release it as they cool. Brands such as Slumber Cloud and Coop Home Goods offer well-reviewed options. Cooling gel pillow inserts or pillows with latex or buckwheat fill also sleep significantly cooler than memory foam. A practical minimum is one cooling pillowcase on your pillow, which costs less than 20 pounds and makes a noticeable difference.
Cooling Mattress Toppers and Bedding
The mattress surface is the biggest heat-trapping factor in bed. Memory foam is the worst offender, retaining heat throughout the night. A cooling mattress topper made from latex, wool, or copper-infused foam addresses this without requiring a new mattress. Wool is particularly effective because it regulates temperature bidirectionally, keeping you cool when hot and warm when cold. Specialist cooling duvets with low tog ratings (2.5 to 4.5 tog) or moisture-wicking fill materials such as bamboo or eucalyptus fibre are worth investing in if night sweats are disrupting sleep regularly. Bamboo sheets are a widely available, affordable upgrade that many women with hot flashes notice immediately.
Personal Fans and Cooling Devices
A small personal fan on the bedside table or desk can interrupt a hot flash quickly by increasing air movement across the skin. For the desk or office, compact USB-powered fans are discreet and powerful enough to provide cooling without drawing attention to yourself during a flash at work. Handheld misting fans combine fine water spray with air movement for rapid evaporative cooling and are particularly useful in hot weather or during exercise. The Dyson Pure Cool range offers more powerful room cooling for the bedroom alongside air purification. A simpler option that many women swear by is a small floor fan pointed at the bed, angled upward. Running at low speed through the night maintains air movement and reduces the waking impact of night sweats significantly.
Cooling Towels and Wrist Wraps
Cooling towels made from PVA or specialised synthetic fabrics are used by athletes but work equally well for hot flashes. You wet the towel, wring it out, and snap it in the air to activate the cooling effect. Draped around the neck or wrists, they lower core body temperature perception within minutes. The wrists are a particularly effective cooling point because large blood vessels run close to the skin surface, meaning cooling this area affects overall body temperature quickly. Dedicated cooling wrist wraps designed specifically for hot flashes are available and discreet enough to wear in the office. Some women keep a damp cooling towel in the fridge during summer for a fast-access solution.
Cooling Sleepwear
What you wear in bed affects how well any other cooling product works. Tight-fitting synthetic sleepwear traps heat and moisture. Loose-fitting, moisture-wicking fabrics allow sweat to evaporate efficiently. Bamboo pyjamas are the most popular choice among women in perimenopause: bamboo fabric is naturally temperature-regulating, soft against skin that may be more sensitive during hormonal fluctuation, and more effective at moisture management than cotton. Brands such as Magnolia Lounge, Bamboo UK, and LNDR offer options across different budgets. Layering a lightweight camisole under or instead of a pyjama top allows you to remove a layer quickly during a night sweat without fully waking your partner.
Smart Cooling Devices
For women with frequent and severe night sweats, dedicated sleep cooling technology offers more reliable relief. The Chili Pad and BedJet are two well-known options that circulate cool water or air directly through the mattress or bed covers. They allow precise temperature control and some models support dual zones so a partner is not affected. These products represent a higher investment (typically 200 to 600 pounds) but are consistently rated highly by women with severe sleep disruption from night sweats. Wearable cooling devices such as the Embr Wave use thermoelectric cooling applied to the wrist to send cooling sensations to the brain, reducing perceived hot flash intensity. Clinical trials on wrist-cooling technology show modest but real benefits for hot flash severity scores.
