If you have experienced a hot flash during menopause, you’ve probably realized it’s unmistakable and quite remarkable. The sudden burst of warmth experienced specifically in the upper neck, chest and face, the increased heart rate, the flushed skin: hot flashes can range in intensity and happen out of nowhere. Whether you’re approaching menopause or in your postmenopausal years, know that you’re not alone: 60-80% of women experience hot flashes at some point during their transition.1

Here, we’ll cover everything you need to know about hot flashes, including what causes hot flashes, what menopause hot flashes feel like, and what you can take to reduce menopausal hot flashes.

What Are Hot Flashes Anyway?

Simply put, hot flashes are the iconic symptom of the menopausal transition. Night sweats are hot flashes that occur during sleep.  Hot flashes are referred to as vasomotor symptoms (VMS). The term “vasomotor" usually refers to blood vessel action i.e. constriction (narrowing) or dilation (widening) of blood vessels. Estrogen, among other  hormones, does have an impact on blood vessels, which is why it has an effect on these symptoms. VMS are very common; in fact, it’s estimated that by 2025, 21 million women in the US and 1.1 billion women worldwide will experience them.2  

Contrary to past generations, menopause and its related symptoms are not thought of as a disease, but rather as just another life stage. And the menopause taboos are lifting, slowly but surely.

Every woman’s experience with menopausal hot flashes can vary; in many cases, hot flashes are truly disruptive to day-to-day life, while in others, they are a mere inconvenience. And for a lucky few, they may be essentially nonexistent.

What Causes Hot Flashes?

Truth be told, the underlying cause of hot flashes is still poorly understood. In very basic terms, hot flashes occur when the master thermostat in the brain, aka the thermoregulatory zone in the hypothalamus, goes awry. Women have a very small window of temperature tolerance during this time, and even a slight variation in environmental temperature can cause a hot flash. Diminishing estrogen levels are clearly involved in this intolerance to temperature changes. Specific neurons and receptors in the brain, neurotransmitters including serotonin, and vascular changes are also all influential on the thermoregulatory zone as well. 

What Do Hot Flashes Feel Like?

Hot flashes are not fun! When asked about how their hot flashes feel, my patients often say, “it’s like a furnace is erupting inside me.” In general, if you’re wondering what hot flashes feel like, women mostly report a sudden and incredibly intense feeling of heat.  This overwhelming sensation typically starts in the chest and neck and then moves quickly to the face.  The face may become beet red.  Excessive perspiration, followed by chills can occur.  Timing, frequency, and severity of hot flashes can vary, and they can be visibly noticeable to others. 

Most hot flashes last from 1-5 minutes. They can occur occasionally or seem constant throughout the day and night. There really is no “normal” number of hot flashes day-to-day, but most women note individual patterns and triggers.  

But, what exactly does a hot flash feel like, and is it the same for everyone? Symptoms may vary in levels of severity and intensity:

  • Mild hot flashes: a sensation of heat without perspiration
  • Moderate hot flashes: a heat sensation combined with sweating but not interfering with activity
  • Severe hot flashes: flashes disrupt activity and can be truly debilitating and life altering

What Age Do Hot Flashes Start?

Hot flashes usually start during perimenopause. This is the approximate 4-8 years prior to menopause when hormone fluctuations are notable. 

Menopause is often acknowledged in hindsight since it’s defined as 12 consecutive months without menses. The average age of menopause is 51 years in the US but can range from age 40 to the late 50s.You may find a genetic association to when your hot flashes begin; many women experience a similar age of onset and experience as their mothers or sisters, barring any significant lifestyle differences.  

How Long Do Hot Flashes Last?

On average, 60-80% of women will experience hot flashes throughout menopause. Data suggests hot flashes last on average 7.4  years but have been reported for upwards of 15 years total. In addition, data suggests frequency and duration do vary by  ethnicity, with Black and Hispanic women reporting increased symptom duration, followed by White and then Asian women.3   

What Causes Feelings of Hot Flashes, Other Than Menopause?

Hot flashes can be symptoms associated with certain medical conditions that are completely unrelated to menopause; therefore, it’s vital to identify and exclude these potential causes. These could include things like:

  • infections
  • diabetes
  • cancer
  • thyroid disorder
  • certain medications

If you are a woman younger than age 40 and experiencing drenching sweats at night, random fever and chills, and rapid weight change, ensure you address this with your healthcare provider.  A good medical history, physical exam, blood work and imaging might be in order before blaming your hormones. 

Are There Common Hot Flash Triggers?

Lifestyle habits might be to blame for the frequency and severity of hot flashes.  Consider your diet carefully.  Caffeine, artificial sweeteners, large meals and spicy foods are common culprits.

Always have plenty of cool water on hand, since adequate hydration tends to mitigate feelings of hot flashes.  Alcohol, particularly red wine, can bring on hot flashes.  Smoking also triggers hot flashes: in fact, regular smokers tend to experience menopause at an earlier age and have more severe symptoms.  

Sedentary lifestyle and obesity are directly correlated with hot flash occurrence. Choice of clothing material and fit can make those with flashes more or less comfortable. My hot flashing patients often tell me that they have given away all their turtlenecks and avoid silk in fear of perspiration. Finally, stress is an incredibly common trigger.

Hot Flash Feelings at Night

Hot flashes that happen at night can definitely disrupt sleep.  Women report a myriad of symptoms including difficulty both falling asleep and staying asleep.  Constant awakening interrupts normal sleep patterns, leaving many women feeling unrested, groggy and foggy during daytime hours. Furthermore, constant awakening allows the “busy mind” to take over in the middle of the night, which can make getting back to sleep torturous. Good sleep hygiene practices include a cool, ambient room temperature, moisture wicking sleep clothes, a comfy mattress and avoidance of screen time just before bed – which all can help to reduce feelings of hot flashes as well.

How to Handle Menopause Hot Flashes

Thankfully, there are numerous options available for the management of menopausal hot flashes.

Prescription Options for Dealing with Hot Flashes

  • The most common treatment for hot flashes is hormonal replacement therapy (HRT) also referred to as menopausal hormone therapy (MHT). The efficacy of HRT is excellent. HRT comes with some baggage however, causing the appetite for HRT to wax and wane over the years. Risks might include a heightened risk of breast cancer, uterine cancer and cardiovascular events including blood clots. The decision to use HRT is a shared one between a woman and her healthcare provider and should be individualized.
  • Prescription medications may help with managing menopausal hot flashes. Surprisingly, various antidepressants have been shown to reduce hot flash frequency.4 Potential side effects and individual circumstances must be taken into account when considering a prescription treatment for hot flashes, but this avenue has been particularly helpful for those who are dealing with underlying depression or anxiety.
  • Gabapentin, a prescription medication used in neurology for seizure control and nerve pain, has been shown clinically to reduce hot flashes.5
  • Vitamins and Dietary Supplements to Address Hot Flashes
  • If you’re looking for dietary supplements to take for hot flashes, black cohosh, evening primrose oil and other “phytoestrogens” are available over the counter; these are plant-derived, “estrogen-like” supplements, which have been commonly used for years. Most clinical studies however, suggest no favorable effect or only minimal relief above placebo – and they may also come with some hormonal side effects, so it’s best to always discuss the decision to include these types of supplements into your routine with your healthcare provide, first.
  • I also recommend a supplement called Relizen®, which is a hormone-free prescription-free product whose key ingredient is a proprietary blend of Swedish Flower pollen. This product has been clinically shown to reduce the frequency and intensity of menopausal hot flashes over time with consistent use.*

Lifestyle Changes That May Help with Hot Flashes

  • Lifestyle matters, as does what you eat. I typically recommend the Mediterranean diet, which is naturally low glycemic, heart healthy and helpful for weight management. Limiting carbs, processed food and sugar allows for steady glucose and insulin levels and diminished hot flashes as a result.
  • Adequate exercise is advised not only for caloric burn and heat dissipation, but also for weight management and stress relief. While exercise in and of itself does not minimize hot flashes, the secondary effects of exercise can. The standard recommendation is 150 minutes a week of cardio, with the addition of strength and flexibility training.  
  • Meditation, mindfulness exercises, and yoga allow for stress relief.

Menopausal hot flashes might be a non-issue for some but can be quite debilitating for others. They are incredibly common but likely won’t last forever, however, it’s important to remember that every woman's experience is different. Be proactive with lifestyle changes and open up a candid dialogue with your healthcare provider. Your quality of life is what’s most important.

I went through menapause at age 42, it happened one time, I became soaked, but never had hot flashes. For the past few years , only when I fall to sleep I get cold sweets,soaking wet. I don’t know if this will help, but I’m trying it. I have autoimmune disorders, and not one doctor can help with sweats.

Menopause started for me at 43. I took ERT for 15 years and had to stop as I got DCIS breast cancer. Got off ERT in 2010, I’m now 69 and these hot flashes day and night are killing me. I sure hope this helps.

I use Relizen for hot flashes. It was recommended by my gynecologist. This was one of the best decisions I’ve ever made. No more waking in the middle of the night needing to take off my sweat soaked pajama top! Thank you!
