Getting a hot flash when rolling over in bed, especially at night, often points to menopausal hormonal shifts that make your internal thermostat oversensitive, with movement or small temperature changes triggering sudden warmth, flushing, and sweating because of estrogen drops affecting the brain's hypothalamus. Lifestyle factors, stress, and even your adrenal system can play a role, so speak with a doctor for diagnosis and treatment, as options range from hormone therapy to stress management or non-hormonal medications.
But most research suggests that hot flashes happen when lower estrogen levels cause the body's heat manager, also called the hypothalamus, to respond to slight changes in body temperature. When the hypothalamus thinks the body is too warm, it starts a chain of events in the form of a hot flash to cool down.
Basically, anything that causes your body to heat up can trigger a hot flash. Simple things such as bending over, blow drying your hair with heat, or even wearing tight clothing can cause hot flashes.
3. Jitters With this sensation, you either start to shake, or you might find that you get tingling sensations, electrical shocks, or pins and needles up your arms, and this tends to happen just before you get the hot flush. This one tends to be caused by something called an adrenal rush.
"Once a hot flash starts," Vinta says, "only cooling is going to stop it." The flipside of this equation is that heat can make things worse. Hot environments, spicy foods and cigarette smoke may trigger hot flashes, so it can help to avoid these things.
These familiar symptoms of menopause appear in most women around age 50. But if they arise before age 40—which happens for about 1 in 100 women—it's a sign that something's wrong.
Physicians need to be aware of medical conditions that may mimic hot flashes (26). These include flashing caused by systemic diseases such as carcinoid syndrome, systemic mast cell disease, pheochromocytoma, medullary carcinoma of the thyroid, pancreatic islet cell tumors, and renal cell carcinoma.
Women and men who are diagnosed with carcinoid tumors, medullary thyroid cancer, pancreatic cancer, or renal cell carcinoma may report hot flashes that are believed to be primarily due to tumor secretion, though detailed studies in the literature are lacking.
While menopause is one of the most common causes of hot flashes, thyroid disorders are also a common cause. Viral infections like the flu can cause hot flashes, too, as can certain medications. If you have hot flashes and aren't in perimenopause, another condition or factor could be responsible.
When I move or turn over in bed it seems to trigger a hot flush. Why? The nervous (adrenal) system often causes flushes/sweats in the menopause so in this case the actual movement of the body may be enough to cause the adrenal system to trigger a flush.
Your autonomic nervous system controls things you don't have to think about, like your breathing, heart rate, blood pressure, body temperature, and sweating. Anything that throws off how it works can cause flushing. That includes Parkinson's disease, epilepsy, MS, and spinal injury and nerve damage.
Four groups of symptom patterns emerged. The patterns included: early symptom onset, beginning 11 years before the final menstrual period and declining after menopause; onset of symptoms near the final period with a later decline; early onset with high frequency of symptoms; and persistently low frequency of symptoms.
Hormones out of whack can show up as mood swings, fatigue, unexplained weight changes, irregular periods, skin issues (like acne), hair loss, low libido, sleep problems, digestive issues (constipation/diarrhea), temperature sensitivity, and brain fog, affecting metabolism, energy, and emotional regulation. Recognizing these signs, like persistent fatigue, heavy periods, or new-onset anxiety, helps prompt a doctor visit for diagnosis and treatment.
Lifestyle changes to improve hot flashes
Start with these lifestyle changes, but if you're not seeing relief, consider talking to your gynecologist about prescription medication. You should always see a doctor about hot flashes if they are: Severe. Interfere with your sleep or daily life.
Some types of Hodgkin lymphoma and non-Hodgkin lymphoma cause night sweats and high temperatures that come and go with no obvious cause. This symptom, along with other tests can help diagnose what type of cancer you have. In Hodgkin's lymphoma, there is also a rare condition whereby you might have a fever in cycles.
Studies show that if a woman experiences late-onset menopause (after age 55), she is at greater risk for developing breast cancer and uterine (endometrial) cancer due to a longer lifetime exposure to estrogen.
Excessive sweating, overheating, and hot flashes are common experiences for people living with lupus, especially those with systemic lupus erythematosus (SLE), affecting many of the 1.5 million Americans with the condition.
Hot Flashes & Night Sweats
Hyperthyroidism can cause symptoms similar to hot flashes, such as excess sweating, high body temperature, and heat intolerance. For both people in the menopause transition and people with thyroid disorders, hot flashes can lead to overheating and sweating while you sleep.
Some diseases that can cause hot flashes include cancer of the ovaries, pituitary gland, uterus, and thyroid.
Some women experience an "aura," an uneasy feeling just before the hot flash, that lets them know what's coming. The flash is followed by a flush, leaving you reddened and perspiring. You can have a soaker or merely a moist upper lip. A chill can lead off the episode or be the finale.
Here are the top five vitamins essential for female wellness during menopause.
The peak symptom phase typically occurs during the transition between perimenopause and early postmenopause. Most women experience their worst symptoms for 4-5 years, though the entire menopause journey can last up to 14 years.
