Night sweats and hot flashes can feel like invisible heat waves stealing the comfort out of your nights. One moment you’re asleep, the next you’re overheated, damp, and wide awake — stripped of the deep rest your body craves. Whether the cause is hormonal changes, stress, or simply heavy synthetic bedding trapping too much heat, these nighttime temperature spikes are your body’s way of signaling imbalance.
The good news? You have more control than you think.
By understanding why night sweats and hot flashes happen — and how your bedroom environment, bedding, and nightly habits influence them — you can relieve discomfort naturally and wake up feeling refreshed instead of wrung out.
This guide breaks down the real causes, natural remedies, and the sleep-supporting power of breathable, moisture-balancing bedding for cooler, calmer rest.
What Causes Night Sweats and Hot Flashes?
Night sweats and hot flashes share a common theme: your body is struggling to regulate temperature. When your internal thermostat misfires, it can trigger sudden heat surges, sweating, and restless wake-ups.
Hormonal Shifts (The Most Common Trigger)
Hormones — especially estrogen in women and testosterone in men — play a major role in thermoregulation. When these hormones fluctuate, your internal temperature control can easily overreact.
This is why:
Women often experience night sweats during perimenopause and menopause
Men can experience “andropause”-related temperature instability
Both can experience temperature spikes from thyroid shifts or cortisol surges
These hormonal dips and spikes explain why “night sweats women” and “night sweats men” are major search categories — and why so many people feel alone in this, even though it’s incredibly common.
Stress and Anxiety
Stress isn’t just mental — it’s physiological. Elevated cortisol increases heart rate, raises core temperature, and triggers sweating. If your days feel stressful, your nights may too.
Medications
Some medications list sweating, overheating, or hot flashes as side effects:
Antidepressants
Hormone therapies
Fever reducers
Steroids
If symptoms started after a medication change, your doctor can help assess alternatives.
Infections
Certain infections — from flu to more serious bacterial conditions — can cause temperature spikes. This is less common but worth noting.
Sleep Disorders
Conditions like sleep apnea raise heart rate and respiratory effort, which can cause night sweats and overheating. Even mild sleep disruptions can elevate core body temperature.
When Bedding Is the Real Culprit
One of the most overlooked causes?
Synthetic bedding and down alternatives that trap heat and moisture.
If you’re sleeping under:
Polyester
Microfiber
Memory foam toppers
Down-alternative comforters
…you’re likely creating a humid microclimate that amplifies night sweats.

Hot Flashes vs Night Sweats: Why They Feel Different — But Are Connected
Hot flash: A sudden surge of heat that can happen anytime — day or night.
Night sweat: Excessive sweating that occurs while you’re asleep.
Many people experience both, especially during hormonal shifts.
Why?
Because hot flashes can trigger night sweats, and night sweats can mimic hot flash heat surges — making them feel interchangeable even though they’re slightly different physiologically.
Understanding this overlap helps you target the right solutions.
How Temperature Affects Your Sleep Stages
During healthy sleep, your core temperature naturally drops by about one degree. This drop helps your body transition into deep, restorative sleep stages.
When you overheat:
Your brain gets “wake up” signals
Deep sleep becomes shallow sleep
You wake groggy even after 8 hours
Your body struggles to reset
This is why “why do I wake up sweating at night?” is one of the most commonly searched variations around night sweats.
Lifestyle Factors That Make Night Sweats Worse
Some triggers are surprisingly simple:
Overheated Bedroom
The ideal sleep temperature is 60–67°F (15–19°C). Many bedrooms run several degrees hotter, especially in summer.
Heavy or Synthetic Sleepwear
Breathability matters. Sweating into polyester traps heat against your skin.
Caffeine, Spice, or Alcohol Before Bed
All stimulate thermogenesis — your body's heat production.
Late-Night Exercise
Your core temperature can stay elevated for hours.
Poor Ventilation
Closed windows, no airflow, or stacked layers make escaping heat nearly impossible.
The Best Natural Remedies for Night Sweats and Hot Flashes
Here is where your bedding becomes the real hero.
Switch to Breathable, Moisture-Balancing Bedding
Synthetic and down-alternative comforters create a hot, humid bubble around your body. Natural fibers — especially regenerative wool — do the opposite.
Wool doesn’t just trap air.
It moves moisture vapor, helping your body maintain its natural temperature rhythm.
This means:
No damp sheets
No clammy wake-ups
No heat pockets
No “kick off the covers at 2am” cycles
Organic wool is one of the best natural treatments for night sweats because it supports thermoregulation instead of fighting it.
Organic Cotton Sheets for Breathable Comfort
Lightweight organic cotton promotes airflow and reduces overheating. It pairs perfectly with wool because it stays cool against the skin and dries quickly.
Adjust Your Bedroom Environment
Use fans or cross-ventilation
Blackout curtains to block heat
Breathable mattress topper (not foam)
Keep a steady nighttime routine
Hydrate Throughout the Day
Hydration helps your body regulate temperature more effectively.
Relaxation Techniques
Lower evening stress = fewer cortisol spikes = cooler sleep.
When Medical Advice Is Important
If night sweats or hot flashes are:
Sudden
Severe
Paired with fever, weight loss, or extreme fatigue
Persistent after lifestyle changes
…it’s time to check in with a healthcare professional.
This protects your health and rules out underlying conditions.

FAQs on Wool Duvet Inserts, Comforters & Sustainable Bedding
What causes night sweats and hot flashes at night?
Night sweats and hot flashes are often caused by hormonal changes, stress, warm bedroom temperatures, heavy or synthetic bedding, medications, or disrupted sleep cycles. When your internal thermostat becomes sensitive or overstimulated, your body produces sudden heat surges that can wake you up drenched or overheated.
What’s the difference between night sweats and hot flashes?
Hot flashes are sudden waves of heat that can happen anytime, while night sweats refer specifically to excessive sweating during sleep. Many people experience both, especially during hormonal shifts, because hot flashes at night can trigger intense sweating while you’re asleep.
Why do women experience night sweats and hot flashes more often?
Women commonly experience night sweats and hot flashes during perimenopause and menopause due to fluctuations in estrogen, which plays a major role in temperature regulation. These hormonal shifts can make the body more sensitive to heat and cause sudden temperature spikes during sleep.
Can men also get night sweats and hot flashes?
Yes. Men can experience night sweats and hot-flash-like heat surges due to stress, low testosterone, medications, infections, or sleep disorders. While less common than in women, hormonal changes in men can also affect temperature regulation and cause overheating at night.
Do natural bedding materials help with night sweats and hot flashes?
Yes. Natural fibers like wool and organic cotton breathe better, wick moisture away, and prevent heat from getting trapped around your body. Wool is especially effective because it regulates temperature and moves moisture vapor, helping you stay cool, dry, and comfortable during night sweats and hot flashes.
How can I stop night sweats and hot flashes naturally?
You can reduce symptoms naturally by keeping your bedroom cool, using breathable bedding, lowering evening stress, staying hydrated, avoiding heavy meals and alcohol before bed, and choosing moisture-wicking sleepwear. Many people find that switching to natural wool bedding offers quick relief.
When should I talk to a doctor about night sweats or hot flashes?
You should contact a healthcare professional if night sweats or hot flashes are severe, sudden, paired with fever or weight loss, or affecting your daily life. Persistent symptoms may need medical evaluation to rule out underlying health conditions or medication effects.
Why do night sweats feel worse with synthetic bedding?
Synthetic materials like polyester and down alternatives trap heat and moisture, creating a warm, humid microclimate around your body. This intensifies sweating and makes it harder for your body to cool down naturally. Natural fibers allow heat to escape and moisture to evaporate, preventing that sticky, overheated feeling.
What type of comforter is best for night sweats and hot flashes?
A lightweight, breathable comforter made from natural wool is ideal. Wool regulates temperature, manages moisture vapor, and prevents heat buildup through the night. Organic cotton duvet covers also improve airflow, creating a cooler and drier sleep environment for hot sleepers.
Can my sleep environment trigger night sweats and hot flashes?
Yes. A warm bedroom, lack of airflow, heavy bedding, memory foam mattresses, and overheated sleepwear can all trigger or worsen night sweats and hot flashes. Optimizing your sleep environment — especially your bedding — is one of the fastest ways to reduce nighttime overheating.
