What Happens to Your Body During a Hot Flash?

Posted on September 11, 2026 by Patrick Hercules

A hot flash is a sudden warm feeling in the upper body, usually the most intense over the face, neck, and chest. Hot flashes are most commonly caused by menopause.

Menopause is when the menstrual period stops for good, with most women experiencing a hot flash about four and a half to five years after their last period. It is diagnosed after 12 months without having a menstrual period, vaginal bleeding, or spotting.

During a hot flash, a woman might feel like she is spiking a high fever, but physiologically, that isn’t what is happening. As women approach menopause and the ovaries begin to produce less estrogen, the hypothalamus, the brain’s internal thermostat, becomes hypersensitive to even small shifts in temperature.

When a woman experiences a hot flash, the body believes it is overheating, even when the actual temperature hasn’t changed much. In response to this, the body tries to cool down as blood vessels dilate, which is supposed to help dissipate some of that heat, triggering a sweating reflex.

How an individual woman experiences hot flashes varies greatly. Some women describe very mild symptoms, while others suffer from profuse sweating. Additionally, some women only have hot flashes during the day, while others have regular night sweats. According to the American College of Obstetricians & Gynecologists, about four in five women experience hot flashes at some point during the menopause transition.

Common triggers of hot flashes include:

Alcohol

Caffeine

High sugar intake

High processed foods

Stress

Black women are more likely to experience more severe and longer-lasting symptoms, sometimes up to 11 years, and research shows that women with more severe, longer-lasting hot flashes and night sweats appear to be at higher risk of cardiovascular disease.

For decades, hot flashes were blamed solely on the loss of estrogen, but that explanation left some questions unanswered because not every menopausal woman has night sweats. What’s more, it doesn’t explain why perimenopausal women experience hot flashes while they still produce estrogen.

Newer research has shown that when the brain recognizes that a woman’s estrogen levels are low, nerve cells in the hypothalamus called KNDy neurons become overactive, releasing neurotransmitters, which include kisspeptin, dynorphin, and neurokinin B.

For women in the middle of their hot flash years and the ten percent of menopausal women who continue to experience them, here are some strategies and tips that can help you manage your hot flashes:

Keep your core body temperature as cool as possible

Keep cool at night

Watch what you eat and drink

Refrain from smoking

Maintain a healthy weight

Reduce your stress

Exercise regularly

When you feel a hot flash coming on, take several slow, deep breaths and try to relax

Drink a glass of cold water and sit calmly until it passes

Wear layers you can easily take off when you feel yourself getting hot

Once a hot flash starts, there is no instant cure. Talk to your healthcare professional about medications and complementary therapies that make the most sense for you and your symptoms.

If you are experiencing hot flashes due to menopause, the most effective way to relieve the discomfort from them is to take estrogen, but taking it carries risks.

Other treatments for hot flashes can include:

Medications

Antidepressants, anti-seizure drugs, and other medications

Hormone therapy

Mind and body approaches

Cognitive behavioral therapy (CBT)

Hypnosis

Mindful meditation

Acupuncture

Dietary supplements

Menopause and Memory Issues

Posted on July 18, 2025 by Patrick Hercules

Menopause occurs when a person goes 12 consecutive months without a menstrual period. Memory lapses and trouble concentrating are common symptoms of menopause and even perimenopause. These menopausal symptoms are caused by the female sex hormone estrogen, which is necessary for maintaining sexual and reproductive health.

Low estrogen levels can cause temporary bouts of brain fog and impact verbal memory, including the ability to recall words and names. However, this type of menopause-related forgetfulness isn’t the same as the early signs of dementia.

Dementia is a general term that represents a group of diseases and illnesses that cause a decline in cognitive functioning to the point that it interferes with a person’s daily life and activities. It is caused by damage to the brain, affecting its nerve cells and destroying the brain’s ability to communicate with its various areas.

The first signs of dementia are typically things like getting lost in familiar places or confusion about how to perform everyday activities, such as driving home from the store, and inability to remember names.

Another key factor in someone affected by dementia is age. Alzheimer’s disease mainly affects people over the age of 65. Less than 10% of cases occur in people younger than 65, especially those without a family history of early-onset Alzheimer’s.

Menopause, on the other hand, usually happens in your mid-40s to mid-50s, and perimenopause can start years earlier.

Midlife “brain fog” can be frustrating and worrisome at times. However, with some extra care and attention to your health, it can be managed and controlled.

Here are some ways to cope with menopausal memory issues:

Get enough sleep

Eat a balanced diet that includes brain-enhancing foods, such as cruciferous vegetables rich in color, to serve as antioxidants

Create and stick to a regular exercise routine

Stop multitasking, as it can drain the brain’s abilities

Exercise your brain by doing activities that can improve your mental fitness, such as:

Doing crossword puzzles, board games, or chess

Going for a vigorous walk

Reading a novel

Taking up a new physical activity, such as ballroom dancing or boxing

Meditating

Starting a journal about positive experiences

Learning a foreign language

Trying tai chi

Understanding Menopause

Posted on October 6, 2020 by Jamaica Hospital Medical Center

The life stages of women’s reproductive health begin with puberty (menstruation) and end with menopause. Menopause marks the time when a woman stops having her period and is no longer able to reproduce. While this stage is a normal part of life it has its challenges as women may experience several, physical and emotional changes. Here are six simple facts to educate and help prepare you for potential changes ahead.

What is menopause?

Menopause is medically defined as the time in a woman’s life when she has not had her period for 12 months after her last menstrual cycle. Her ovaries will cease to further produce eggs.

When does it happen?

The average age for women living in the United States to experience menopause is 51 years old. However, in some cases, it can occur as early as a woman’s 30’s or as late has her 60’s. Symptoms can begin to present a few years earlier before the actual onset of menopause. This stage of your reproductive health is referred to as perimenopause.

What are the symptoms?

The symptoms of menopause may vary from person to person; they may include:

Hot flashes
Night sweats
A slowed metabolism and weight gain
Vaginal dryness
Mood swings
Trouble sleeping
Thinning hair
Incontinence

How to treat or cope with symptoms?

There are several treatments and lifestyle changes you can apply to help relieve symptoms, some of which are:

Hormone replacement therapy
Getting enough sleep
Strengthening pelvic floor muscles by doing Kegel exercises
Eating a balanced diet
Taking calcium and Vitamin D supplements, as recommended
Exercising regularly
Taking low-dose anti-depressants as prescribed

Can menopause lead to further complications?

Your risk for developing certain health conditions may increase after menopause. Examples of these include osteoporosis and cardiovascular disease

When should I speak to my doctor about menopause?

If you are experiencing unusual pain, other extreme physical or emotional symptoms which affect your quality of life, it is advised that you speak with your doctor as soon as possible. Your doctor may explore treatment options or suggest lifestyle changes. It is also recommended that you begin the conversation about menopause during perimenopause (early menopause symptoms). Your doctor can offer guidance on what to expect.
