You’re going about your life — putting together a work presentation or taking a walk around the block. All of the sudden you feel really hot. Then the sweating starts.

Oh no, is this another hot flash?
While hot flashes can be disruptive and embarrassing, there are things you can do to lessen their effects.
Internal medicine and women’s health specialist Andrea Sikon, MD, explains why hot flashes continue and what may trigger one.
This can vary from person to person. Typically, you may start experiencing hot flashes in your early 40s as your levels of estrogen and progesterone start to decrease. This triggers the start of perimenopause, the transitional period before menopause.
“You can experience hot flashes in perimenopause, before you go through menopause,” says Dr. Sikon.
Most individuals describe a hot flash as a sudden, intense period of heat that’s accompanied by sweating and discomfort. Sometimes, it’s followed by chills.
When they happen during the day, they’re called hot flashes and when they happen during the night, they’re called night sweats. And night sweats can disrupt your sleep, leaving you feeling fatigued, irritable and more forgetful.
You may not experience vasomotor symptoms (hot flashes and night sweats) during menopause. But for those who do, the severity and length of time of each hot flash can vary from person to person. One hot flash may be just a few minutes, while others may last for more than 5 minutes.
And when it comes to how many years you may have hot flashes, that varies as well.
“On average, they can last for four to seven years,” says Dr. Sikon.
It can be hard to predict when you may have a hot flash.
And unfortunately, there are a handful of things that can trigger a hot flash. But once you learn what triggers your hot flashes, you can work on avoiding or limiting them.
Common hot flash triggers include:
In addition to these common triggers, certain medications like tamoxifen, which is used for breast cancer, or raloxifene, an osteoporosis medication that can also be used for breast cancer prevention, and certain antidepressants can cause hot flashes as well.
Once you enter menopause, which is the cessation of your menstrual cycle, you stay in it forever, says Dr. Sikon.
Most individuals will experience hot flashes for about four to seven years before their symptoms stop. Some experience them for longer.
But can your hot flashes stop and then come back?
“It’s not typical,” says Dr. Sikon. “They can be episodic where you may not have one for months but then they come on again. This is especially true in perimenopause, when your periods may be starting and stopping. But once you’ve completely stopped having periods and are in menopause, it’s highly unlikely that hot flashes would be gone for years and then come back.”
In addition to learning what your triggers are, there are treatment options available. Talk to your doctor if your hot flashes are affecting your daily life.
Your doctor will discuss whether hormone therapy, prescription medication or alternative therapies are right for you. Make sure you talk to a provider who has experience in treating them, as there is a lot of misinformation on hormone therapy and a lack of training for many. Many options exist to help with the symptoms.
“Hot flashes are natural,” notes Dr. Sikon. “It’s easy to be dismissive of them but for some people, hot flashes can be very intense. Identifying your triggers and seeking medical treatment can help.”
