Hot Flashes: Why They Happen and How to Manage Them

Hot flashes are sudden waves of heat that spread through the body, often affecting the face, neck, and chest. They can come on quickly and create a feeling of intense warmth, flushing, and sweating.

For many women, hot flashes are linked to menopause. They can also happen during perimenopause or other hormonal shifts. Each episode may last anywhere from a few seconds to several minutes.

Although hot flashes aren’t dangerous, they can disrupt your daily routine, your sleep, and make you feel uncomfortable in social or work settings. Learning how they play out in your body can make these moments less confusing—and much easier to manage.

 

Hot flash symptoms can vary, but many women experience similar physical sensations, such as:

• Sudden warmth spreading across the upper body
• Flushing or darkening of the skin, especially on the face and neck
• Intense sweating, particularly on the chest, back, or in the armpits
• A rapid or irregular heartbeat
• Feeling cold as the hot flash fades
  

 

Hot flashes can be triggered or made worse by different factors. Here are some of the common ones:

 

Hormonal changes

Hormonal shifts in perimenopause, menopause and after menopause can trigger hot flashes.¹ Research suggests that when estrogen levels fall, the body’s built-in “thermostat” (the hypothalamus) becomes more sensitive.¹ It can mistake tiny shifts in temperature as overheating, setting off a hot flash to bring your body back to balance.

Hot flashes can continue for several years during menopause. Some women also experience them after menopause, although they often become less frequent as time goes on.

 

Lifestyle factors

You might be surprised to learn that even everyday habits can influence how often hot flashes happen and how intense they feel. Common triggers include:

• Spicy foods
• Caffeine
• Alcohol
• Smoking
• High stress levels

Cutting back on caffeine, managing stress, or noticing which foods set off your symptoms can help you feel more in control and may reduce how often you get hot flashes.

 

Medical conditions and medications

In some cases, hot flashes may be linked to other health conditions or treatments.

• Thyroid conditions like hyperthyroidism²
• Certain medications¹
• Cancer treatments like chemotherapy or hormone therapy³

A healthcare professional can help you figure out if an underlying condition might be playing a role in your symptoms.

 

Age

Hot flashes are most common between the late 40s and early 50s, which is when menopause typically occurs.

 

Genetics and race

Family history may influence how likely you are to experience hot flashes. Research has also shown differences in how often women experience them across racial groups. Some studies suggest African American women may have hot flashes more frequently and find them more bothersome than Caucasian women.⁴

 

Many women experience hot flashes at night, which can interrupt their sleep and leave them feeling exhausted the next day.

Nighttime hot flashes happen because the body’s temperature regulation system becomes more sensitive during sleep. When a hot flash occurs, sweating may become more intense.

Cool bedding, breathable fabrics, and maintaining a comfortable bedroom temperature can sometimes help manage these nighttime symptoms.

 

Hot flashes and night sweats are closely related but not identical. Night sweats refer to episodes of excessive sweating during sleep. These may be caused by infections, medications, or hormonal changes.

Hot flashes at night are typically linked to menopause and involve the same sudden heat sensation experienced during daytime hot flashes.

 

Managing your hot flashes involves a mix of supportive care, lifestyle adjustments, and medical guidance when needed.

 

Medical treatments

Hormone replacement therapy (HRT) can help balance your hormone levels and ease hot flashes. Some non-hormonal options may also give you relief. A healthcare provider can find the approach that feels right for you, based on your health history and symptoms.

 

Dietary adjustments

Cutting back on spicy foods, caffeine, and alcohol can help, while focusing on balanced meals packed with nutrient-rich foods like fruits, vegetables, whole grains, and lean proteins supports your overall health. Staying well-hydrated throughout the day is also good for your health. Small tweaks to your daily diet add up and can really make a difference in how you feel.

 

Stress management

"Emotional stress, anxiety, or fear can trigger the body’s fight‑or‑flight response, activating sweat glands even at rest," says Unilever R&D Manager David Waters.

This is why practices such as yoga, meditation, gentle stretching, or deep breathing exercises are often recommended to help calm the nervous system and reduce the intensity of your symptoms. Making time for relaxation during the day can also help you sleep better at night.

 

Cool-down strategies

These easy habits can help you with your day-to-day comfort:

• Wearing lightweight, breathable clothing
• Using fans or opening windows for airflow
• Lowering the room temperature (if you have air-conditioning)
• Taking a cold shower

 

Managing sweating

Hot flashes with their unexpected bursts of sweat can leave your clothes damp and your skin feeling sticky.

Using gentle, breathable products that control odor while supporting your skin can help you feel fresher and more confident, even during the hottest moments.

Products like SheaMoisture Aloe Vera & Ceramides Sensitive Antiperspirant Deodorant Stick help you stay fresh and protected, no matter how your body temperature shifts throughout the day.

If sweating is more widespread, SheaMoisture Whole Body Deodorants are gentle enough for all-over use to help keep odor under control.

Although hot flashes are common, you don’t have to struggle by yourself if your symptoms are affecting your daily life. Your doctor can help you manage them better. Medical advice is also advised if your hot flashes:

• Disrupt your sleep regularly
• Occur alongside unexplained weight loss
• Include severe heart palpitations
• Feel unusually intense or sudden

Your doctor can identify the possible cause and treatment options to help you feel better and more in control.

How can you stop hot flashes quickly?

While it's not possible to stop hot flashes, certain strategies can help reduce their intensity. Cooling the body by drinking cold water, using a fan, or moving to a cooler environment may provide some relief.

 

Do hot flashes happen after menopause?

Yes, hot flashes after menopause are still possible. Although they are most common during perimenopause and menopause, some women continue experiencing menopause hot flashes for several years afterward. With time they can become less frequent and less intense, but lifestyle adjustments and supportive treatments can help manage symptoms if they continue.

Hot flashes are a common and natural experience for many women as their hormones shift. While they can be uncomfortable and sometimes disruptive, there are practical ways to make these episodes more manageable. By trying a few strategies, you can feel more comfortable, confident, and maybe even a little empowered as you navigate this phase.
