Waking up hot, sweaty, and suddenly desperate to get the covers off is one of the more frustrating ways perimenopause can interfere with sleep.
A fan won’t stop hot flashes from happening. But when a hot flash occurs at night, having cool air where you need it can help you feel more comfortable without having to lower the temperature of the entire bedroom.
You don’t necessarily need the biggest or most expensive fan.
For some women, a quiet tower fan that keeps air moving across the bed makes the most sense. If you tend to overheat and sweat underneath the covers, a system that circulates air through the bed may be worth considering.
If you regularly wake up hot or sweaty and want to understand why, our guide to night sweats during perimenopause explains common causes and what may help.
After comparing the options, these three stood out for different reasons — from simple, targeted airflow to more advanced under-cover cooling.

If you’re looking for a straightforward recommendation, the Dreo Tower Fan 518 is the most versatile option for most bedrooms. It provides plenty of control over airflow without requiring a complicated setup or a major investment.
For those who regularly wake up with damp sheets or feel particularly hot underneath the covers, the BedJet offers a more targeted approach by circulating air directly through the bed.
For simple, targeted airflow at a lower price, the Honeywell QuietSet HTF210B is a compact option that can be positioned beside the bed.
Best Overall: Dreo Tower Fan 518
Best for: Quiet, adjustable airflow throughout the bedroom
The Dreo Tower Fan 518 combines strong airflow with plenty of control, making it a versatile option for nighttime hot flashes.
It has nine speed settings, four modes including Sleep and Auto, 90-degree oscillation, and airflow reaching up to 28 ft/s.
Having several speed settings can be particularly useful at night. A low setting may provide gentle airflow while you sleep, while a higher setting can provide more immediate cooling when a hot flash occurs.
The included remote also makes it easy to adjust the airflow without getting out of bed.
Why It Works Well for Hot Flashes
One of the main advantages of a tower fan is its ability to circulate air across a larger area rather than directing it toward one small part of the bed.
The Dreo 518 has 90-degree oscillation, allowing airflow to move across the sleeping area. It can also be used without oscillation when more targeted airflow is preferred.
The 12-hour timer is another useful feature for nighttime use, particularly compared with fans that are limited to shorter timer settings.
Sleep Mode is designed for quieter nighttime operation, while the multiple speed settings make it easier to balance airflow and noise according to personal preference.
Things to Consider
At 42 inches tall, the Dreo 518 requires some floor space beside or near the bed.
It also costs more than a basic personal fan. For someone who only needs a small amount of targeted airflow, a compact fan may be sufficient.
Like any conventional fan, it does not lower the actual room temperature in the way an air conditioner does. Instead, moving air helps the body feel cooler and can support faster evaporation of sweat.
Independent testing of the Dreo 518S measured noise levels at approximately 26.8 dB on the lowest setting, increasing as the fan speed was raised. This makes the lower settings particularly relevant for overnight use, when even relatively small differences in fan noise can become noticeable.
Pros
- 9 fan speeds
- 4 modes including Sleep Mode
- 90° oscillation
- Up to 28 ft/s airflow
- 12-hour timer
- Remote control
- Suitable for wider bedroom airflow
Cons
- Requires more space than a personal fan
- More expensive than a basic fan
- Does not lower the actual room temperature
Bottom line: The Dreo Tower Fan 518 is the most versatile option of the three and a good choice for anyone looking for adjustable airflow throughout the bedroom.

Best for Under-Cover Cooling: BedJet
Best for: Direct airflow underneath the bedding
BedJet works differently from a conventional bedroom fan.
Instead of circulating air around the room, the unit sits beside or underneath the bed and sends air through a hose directly underneath the bedding.
This makes it particularly relevant when overheating and sweating occur mainly under the covers rather than because the entire bedroom feels too warm.
BedJet does not refrigerate the air like an air conditioner. Instead, it circulates room air through the bed, helping to move heat and moisture away from the sleeping area.
What Does the Research Say?
BedJet stands out from the other products in this guide because the system has been studied specifically in women experiencing menopausal hot flashes and night sweats.
A small 2018 study titled The Efficacy of the BedJet Climate System for Peri-Menopausal Night Sweat and Hot Flash Symptoms and Corresponding Impact on Sleep included 46 peri- and postmenopausal women experiencing hot flashes, night sweats, and sleep disturbances.
After using the system for at least three weeks, 85% reported significant improvement in hot flashes and night sweats, while 94% reported improved sleep.
These results are interesting, but they should be interpreted with caution. The study was small and was published as an abstract rather than as a large randomized controlled trial. It therefore does not establish BedJet as a treatment for menopausal hot flashes.
It does, however, provide some relevant research on this particular type of cooling system in women experiencing these symptoms.
Why Under-Cover Airflow May Help
A conventional fan primarily circulates air around the room and across exposed skin. BedJet instead targets the warmer, more humid environment that can develop underneath bedding.
This may be particularly useful when night sweats leave sleepwear or sheets damp.
Keeping air moving can help moisture evaporate more quickly rather than allowing bedding to remain warm and damp for long periods.
Faster drying may also help bedding feel fresher and more comfortable after a night sweat. However, airflow does not prevent odor on its own, and damp sleepwear and bedding still need regular washing.
BedJet can be used with regular mattresses and bedding. An optional Cloud Sheet is also available to distribute the airflow more evenly.
The system includes heating as well as cooling functions, which may be useful for women who feel chilled after a night sweat or once a hot flash has passed.
Things to Consider
The main consideration is cost. BedJet is considerably more expensive than a conventional fan and is unlikely to be necessary for occasional or relatively mild nighttime hot flashes.
It also requires more equipment than a standard fan, including the unit, hose, and air nozzle.
Most importantly, BedJet should not be confused with an air-conditioning system. It circulates ambient room air rather than actively chilling it below room temperature.
Pros
- Directs airflow underneath the bedding
- Targets heat and moisture where they can accumulate during sleep
- Adjustable airflow
- Works with an existing mattress
- Has been studied in women with menopausal hot flashes and night sweats
- Includes both cooling and warming functions
Cons
- Considerably more expensive than a conventional fan
- Requires more setup
- Does not actively chill the air
- Menopause-specific research is limited
Bottom line: BedJet is the most targeted option in this guide and may be worth considering when under-cover overheating and night sweats remain a problem despite ordinary bedroom cooling.

Best Budget: Honeywell QuietSet HTF210B
Best for: Affordable, targeted airflow beside the bed
The Honeywell QuietSet HTF210B is a compact personal fan designed for smaller spaces such as a desk or nightstand.
It has four cooling levels — Sleep, Calm, Refresh, and Power Cool — as well as oscillation and 2-, 4-, and 8-hour auto-off settings.
Its smaller size makes it particularly useful when airflow is needed close to the bed rather than throughout the entire room.
Why It Works Well for Hot Flashes
A personal fan can be particularly useful when only one person in the bed wants additional airflow.
Rather than circulating air throughout the bedroom, the Honeywell can be positioned near one side of the bed and directed toward the person who needs it. This may also be helpful when a partner prefers a warmer sleeping environment.
The four cooling levels provide flexibility between gentle continuous airflow and stronger cooling when needed.
Its compact size also makes it easy to move between rooms.
Things to Consider
The Honeywell does not provide the same level of whole-room air circulation as a full-size tower fan.
Positioning is therefore important. It works best relatively close to the person using it rather than across a large bedroom.
The timer is also limited to eight hours, and unlike the Dreo, this model does not include a remote control.
Pros
- Affordable
- Compact enough for many nightstands
- 4 cooling levels
- Sleep setting
- Oscillation
- 2-, 4-, and 8-hour timer
- Suitable for targeted airflow
Cons
- Less powerful than a full-size tower fan
- Intended for personal rather than whole-room airflow
- No remote control
Bottom line: The Honeywell QuietSet HTF210B is a practical choice for anyone who wants simple, targeted airflow without the cost or size of a full bedroom fan.

Can a Fan Help With Hot Flashes at Night?
A fan cannot prevent hot flashes, but it can help make them more comfortable when they occur.
Hot flashes and night sweats are vasomotor symptoms associated with hormonal changes during the menopause transition. A fan does not address the underlying cause and should therefore be considered a comfort measure rather than a treatment.
Moving air across the skin can support evaporation and heat loss, which may help when the skin suddenly feels hot or becomes sweaty.
The Menopause Society notes that cooling strategies, including changes to clothing and environmental temperature, are commonly used to manage hot flashes. However, there is limited clinical evidence that these approaches reduce vasomotor symptoms themselves.
A fan is therefore best viewed as a comfort measure rather than a treatment for hot flashes.
If hot flashes or night sweats are frequent, severe, or regularly interfere with sleep, it may be worth discussing them with a healthcare provider. Both hormonal and nonhormonal treatment options are available.
Which Type of Fan Is Best for Hot Flashes?
The most suitable option depends largely on where and how cooling is needed during the night.
Tower Fan
A tower fan is a good option when airflow is needed across the bed or throughout the bedroom.
Oscillation can distribute air over a wider area, while multiple speed settings make it possible to use gentle airflow during sleep and increase it when needed.
This is likely to be the most versatile option for many bedrooms.
Bed Cooling System
A bed cooling system may be more suitable when overheating occurs primarily underneath the bedding or when night sweats leave sleepwear and sheets damp.
Instead of circulating air around the room, a system such as BedJet directs airflow into the bed itself.
The main disadvantage is the considerably higher cost.
Personal Fan
A personal fan works well when cooling is needed in a smaller, more targeted area.
It can be particularly useful when one person in the bed experiences hot flashes while the other does not want additional airflow.
Personal fans are also generally the least expensive and easiest option to set up.
What to Look for in a Fan for Nighttime Hot Flashes
A few features are particularly useful when choosing a fan for nighttime use.
Multiple Speed Settings
Cooling needs can vary considerably throughout the night.
A lower setting may be sufficient during normal sleep, while stronger airflow can feel more comfortable during a hot flash. Several speed settings provide greater control over both airflow and noise.
Low Noise
Fan noise can become more noticeable in a quiet bedroom.
Look for a fan that performs well at lower speeds rather than relying solely on the manufacturer’s lowest advertised decibel figure.
Remote Control
A remote control makes it possible to adjust the airflow without getting out of bed when a hot flash occurs.
Sleep Mode and Display Lights
Bright displays can be disruptive in a dark bedroom.
Sleep modes that reduce both noise and unnecessary lighting can therefore be useful for overnight use.
Timer
A timer is useful when the fan does not need to run continuously.
If the intention is to use it throughout most of the night, check that the maximum timer duration is long enough for your normal sleep period.
Oscillation
Oscillation distributes airflow over a wider area and can prevent a continuous stream of air from being directed at the same part of the body.
For targeted personal cooling, however, a stationary fan may sometimes be preferable.
Is It Okay to Sleep With a Fan On All Night?
For most people, sleeping with a fan on throughout the night is generally fine.
However, positioning and maintenance can make it more comfortable.
Continuous strong airflow directed at the face may contribute to dry or irritated eyes, nose, or throat. Positioning the fan so that air moves across the bed or body rather than directly toward the face can help.
A lower setting or oscillation may also be more comfortable for prolonged use.
Fans should also be cleaned regularly. Dust can accumulate on blades and grilles and may be circulated through the room when the fan is running.
For nighttime hot flashes, consider keeping the fan on a low setting and directing the airflow across the body rather than toward the face. If the fan has a remote, keeping it beside the bed makes it easy to temporarily increase the airflow when a hot flash occurs.
Strong airflow may not be necessary throughout the entire night.
Other Ways to Stay Cooler at Night
A fan can be combined with other changes to create a cooler sleeping environment. If you’re looking beyond fans, our guide to the best products for night sweats covers several other options for staying cooler and more comfortable at night.
Lightweight, breathable bedding can help reduce heat buildup, while moisture-wicking pajamas may be useful when night sweats are a significant problem.
Cooling sheets and more breathable mattress materials can also help if heat tends to become trapped around the body during sleep.
These strategies are primarily intended to improve comfort. If hot flashes are significantly disrupting sleep or quality of life, environmental cooling should not replace appropriate medical advice or treatment.
Frequently Asked Questions
What type of fan is best for menopause hot flashes?
For many people, a quiet tower fan with several speed settings is a practical place to start.
A personal fan may be sufficient when cooling is only needed on one side of the bed, while a bed cooling system may be worth considering when overheating and sweating occur mainly underneath the covers.
Should a fan be pointed directly at you while sleeping?
It can be, but continuous airflow directly toward the face may feel drying or uncomfortable over several hours.
Directing the airflow across the body, using a lower setting, or turning on oscillation may be more comfortable for overnight use.
Is a tower fan better for hot flashes?
A tower fan can be particularly convenient in a bedroom because it provides wider airflow while taking up relatively little floor space. Many models also include oscillation, timers, sleep modes, and remote controls.
However, a personal fan may be more suitable when targeted airflow is preferred.
Can a fan stop night sweats?
No. A fan cannot prevent the hormonal processes associated with menopausal night sweats.
It can help the body feel cooler and support evaporation when sweating occurs, which may make nighttime symptoms more comfortable.
If night sweats are severe, persistent, or accompanied by symptoms that concern you, talk to your healthcare provider.
Is BedJet worth considering for menopause?
BedJet may be worth considering when overheating underneath the bedding or significant night sweats continue despite using a conventional fan.
Its under-cover airflow provides a different type of cooling from a standard bedroom fan.
A small 2018 study also reported improvements in hot flashes, night sweats, and sleep among women using the system, although larger controlled studies are needed before firm conclusions can be drawn.
Final Verdict
The best fan for hot flashes at night depends on your needs and how you tend to experience overheating while you sleep.The three products in this guide offer distinctly different approaches to nighttime cooling.
Dreo Tower Fan 518 is the most versatile option for general bedroom airflow, with multiple speeds, oscillation, Sleep Mode, and remote control.
BedJet provides targeted airflow underneath the bedding and is the most specialized option for women who experience significant under-cover overheating or night sweats.
Honeywell QuietSet HTF210B offers a simpler and more affordable solution when targeted airflow beside the bed is all that is needed.
For most bedrooms, a good tower fan is a sensible place to start. More specialized under-cover cooling may be worth considering when ordinary airflow does not provide enough relief.
Whichever option you choose, a fan should be viewed as a way to improve nighttime comfort rather than a treatment for hot flashes themselves.
