Sleep disruptions due to night sweats: When should you see a doctor?
If you’ve woken up in the middle of the night drenched in sweat, it can be a bit scary.
You could be experiencing night sweats, which are usually associated with menopause.
But medical experts say the condition can be caused by other issues or situations as well.
GOOGLE SEARCHES FOR ‘SLEEP’ REACHED ALL-TIME HIGH IN 2023, NEW STUDY NOTES
To find out more, doctors weighed in during interviews with Fox News Digital to share insights into the hot topic of night sweats — and what to do about it.
What are night sweats?
Excessive sweating during sleep, or night sweats, occurs when there is a dysregulation of the body’s natural reaction to excess heat, said Jesus Lizarzaburu, M.D., a family physician with TPMG Grafton Family Medicine in Yorktown, Virginia.

“Symptoms include drenching sweats that may soak your bedding and sleepwear, unrelated to an overheated environment,” Lizarzaburu told Fox News Digital.
What issues can cause night sweats?
Night sweats may be triggered by a number of factors.
Hormonal changes. The most common cause of night sweats is hormonal changes, such as menopause in women, said Dr. Lizarzaburu.
He said this is not limited to females, however.

To a much lesser extent, low testosterone in men may cause night sweats, too.
Medications. Certain medications such as antidepressants, drugs used to treat diabetes (hypoglycemics), hormone-blocking drugs used to treat certain cancers and certain psychiatric drugs may be at the root of night sweats, Lizarzaburu also noted.

Hormone disorders. Conditions including hyperthyroidism or an overactive thyroid gland can cause night sweats, he explained.
Infections. Infections such as tuberculosis, HIV/AIDS, endocarditis (inflammation of the heart valves), osteomyelitis (inflammation within the bones) and even abscesses can cause night sweats, said Lizarzaburu.

“However, I would like to point out that with infections, other symptoms such as fever or localized swelling would be present,” he clarified.
How can night sweats be treated?
Treatment for night sweats really depends on the cause, noted Mike Sevilla, M.D., a family physician with Family Practice Center of Salem in Salem, Ohio.
He said treatment can include lifestyle modifications like avoiding night sweat triggers, sleeping in a cooler room and wearing more breathable clothing.
“I generally start with these initial steps,” Sevilla said.

“There are possible medication options,” he said. “However, I encourage people to check in with their family physician because there could be medical testing involved to rule out possible medical causes for the night sweats.”
There are a host of lifestyle modifications and non-medication options to treat night sweats, he also indicated.
FOR QUALITY SLEEP, TIMING IS EVERYTHING, EXPERTS SAY: HERE’S THE SECRET OF SUCCESSFUL SLUMBER
Here are some examples.
Watch food and drink triggers. “Avoid potential night sweat triggers before bedtime like alcohol, caffeine, nicotine, spicy foods and others,” Sevilla said.
Time your workouts. Increase exercise during your waking hours and not right before bedtime, he noted.
Stay hydrated. He suggests sipping cool water before bedtime.
Wind down before bed. “Consider relaxation techniques like meditation or controlled breathing exercises,” he said.

Create a favorable sleeping environment. Sleep in a cooler room and consider using a bedroom fan, said Sevilla.
Upgrade your bed dressings. Consider investing in a cooling pillow, cooling sheets or cooling mattress.
DO WEIGHTED BLANKETS REALLY DELIVER A SLEEP FIX? HERE’S WHAT YOU NEED TO KNOW
Wear breathable clothing. Wear loose-fitting, lightweight pajamas and dress in layers to name it easy to make adjustments during sleeping hours, he said.
Monitor your medications. Sevilla cautioned that some OTC vitamins and OTC supplements may cause night sweats and/or interfere with prescription medications.
“If you are unable to have a full night of sleep because of night sweats, eventually this disruption will affect your quality of life.”
Maintain a healthy weight. Staying active and being mindful of your diet may play a role in reducing the condition.
When is seeing a doctor warranted?
Seek medical care whenever your quality of life is affected, said Lizarzaburu of TPMG Grafton Family Medicine.
“If you are unable to have a full night of sleep because of night sweats, eventually this disruption will affect your quality of life,” he noted.
Aside from the effects on quality of life and sleep, patients should be concerned the most seriously when they are present along with lymph node swelling, fever and unexplained weight loss, as these can be symptoms of lymphoma, Lizarzaburu told Fox News Digital.
A doctor or health professional can help diagnose the cause of night sweats. (iStock)
A doctor or medical professional can help you diagnose the cause of your night sweats.
“For example, if menopause is the cause, one can start with supplements and escalate to hormone replacement,” said Lizarzaburu.

“If [it’s about] low testosterone in men, testosterone replacement can help.”
He added, “If hyperthyroidism (overactive thyroid) is the cause, medication can be prescribed to counter that.”
And, if medication is causing the night sweats, a prescriber can “re-evaluate the condition to look for alternative medication or to adjust the doses,” he said.

As snow blanketed parts of the U.S. this week, heart health experts have shared warnings of the physical strain shoveling can take — particularly for older adults.
A 2025 Mayo Clinic review found that just 10 minutes of heavy snow shoveling can push the heart to about 97% of its maximum rate. Exposure to cold air was also found to increase blood pressure and reduce coronary blood flow.
While there isn’t an official age that’s “too old” to shovel, some cardiologists recommend that individuals over 45 should exercise more caution to lower their chances of a cardiac event.
When to take caution
“While there’s no strict age cutoff, generally above the age of mid 40s and above, we tend to be a little more cautious — particularly in people who are less active [without] regular exercise,” Dr. Navjot Kaur Sobti, M.D., an interventional cardiologist at Northwell’s Northern Westchester Hospital in Mount Kisco, New York, told Fox News Digital.

“Certainly in people who are above the age of 65 — and who have risk factors for heart disease, such as high blood pressure, high cholesterol, diabetes, obesity or sedentary lifestyle — we recommend being very, very cautious about shoveling snow,” she advised.
Dr. John Osborne, M.D., a practicing Texas cardiologist and volunteer for the American Heart Association, shared similar guidance for people older than 45, especially males over 65.
SIMPLE NIGHTLY HABIT LINKED TO HEALTHIER BLOOD PRESSURE, STUDY SUGGESTS
“Unless you are in good cardiovascular shape and conditioned, it may be a good idea to ask someone for help,” he said in an interview with Fox News Digital.
The impact of snow removal is especially concerning for those with existing cardiovascular risks and a history of heart attack or stroke, according to the cardiologist. “People with these characteristics and those who have had bypass surgery or coronary angioplasty simply should not be shoveling snow in any conditions,” he said.

Osbourne said he often sees cardiac episodes in people who are typically sedentary and sit at a computer most of the day with little or no exercise. “Then once or twice a year, they go out and try to shovel the driveway after a heavy snowfall, and that unexpected exertion can unfortunately lead to tragedy.”
Hidden strain
The stress that is placed on one’s heart while shoveling snow is similar to what occurs during a cardiac stress test, Sobti pointed out, and may even exceed it.
Cold temperatures can cause blood vessels to constrict and blood pressure to spike — which, coupled with existing hypertension and the exertion of lifting snow, can significantly tax the heart, she warned.
“It’s almost like an at-risk person is putting themselves through an unsupervised maximal exertion stress test without a cardiologist actively monitoring them,” Sobti told Fox News Digital.

In addition to the exertion of shoveling, frigid temperatures can also strain the heart. Recent research has shown that cold exposure accounts for nearly twice as many cardiovascular deaths as heat exposure, including heat exhaustion.

That study, published in the Annals of Internal Medicine last month, also found that those over age 65 had higher rates of temperature-related deaths.
“So the risk is very, very high,” Sobti cautioned. “It’s really that sudden rise in blood pressure coupled with the physical stress of snow shoveling itself.”
Safer shoveling tips
The cardiologist said it’s ideal to have someone else help with snow removal — but if you do choose to use a shovel, she recommends pacing yourself and using a “pushing or sweeping” motion instead of heavy lifting.

To protect against the cold, Sobti also recommends covering your mouth, nose and extremities, wearing a hat and gloves, and using extra caution in windy conditions.
Using an automated snow blower can still raise the heart rate — up to 120 beats per minute, compared to 170 while shoveling, the American Heart Association states on its website.

It is also important to be aware of any symptoms of a potential cardiac issue while shoveling, Sobti emphasized.
If a person starts to experience warning signs such as chest pain, shortness of breath, a racing heart or palpitations, those should not be ignored.

Even if the symptoms resolve after a few minutes, a person “could still be experiencing symptoms of a heart attack” and should call 911 for evaluation, Sobti said.
“It’s better really to be safe than sorry.”

More than three-quarters of the global population is falling short on omega-3 intake, a nutrient gap that may increase the risk of heart disease, cognitive decline, inflammation and vision problems.
That’s according to an analysis published in Nutrition Research Reviews, in which researchers from the University of East Anglia, the University of Southampton and Holland & Barrett analyzed omega-3 intake patterns across multiple countries and age groups.
The review found that 76% of people worldwide are not meeting the recommended levels of two omega-3 fats that are essential for heart health: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
TREATING GUM DISEASE COULD REDUCE RISK OF HEART ATTACKS AND STROKES, STUDY SUGGESTS
The analysis considered recommendations from global health authorities and assessed how closely populations follow them.
Most adults should aim for at least 250 milligrams of EPA and DHA per day, though actual intake is far lower in many regions, according to the researchers.

To explore the health implications of low omega-3 intake, Fox News Digital spoke with Michelle Routhenstein, a New York–based preventive cardiology dietitian at Entirely Nourished.
HIGH-POTASSIUM FOODS COULD ‘SIGNIFICANTLY’ LOWER RISK OF HEART FAILURE, STUDY FINDS
Low omega-3 levels can have a noticeable impact on heart health, cognitive function and inflammation throughout the body, the expert confirmed.
Low intake can also increase the risk of heart attacks and sudden cardiac death, she added. It’s also associated with higher triglycerides, irregular heart rhythms and plaque in the arteries.

Inadequate omega-3 levels have also been linked to changes in brain function, including faster cognitive decline, a higher risk of Alzheimer’s disease and increased rates of depression.
Routhenstein noted that low levels may also worsen inflammation in autoimmune conditions such as psoriasis, and can negatively affect eye health, since omega-3s play a key structural role in the retina.
SITTING ALL DAY? NEW STUDY SAYS CERTAIN FOODS MAY PROTECT YOUR HEART FROM DAMAGE
To improve omega-3 levels, the expert said it’s important to understand how much is needed and where to get it.
“The richest dietary sources of EPA and DHA are oily fish, such as salmon, mackerel, sardines, herring, trout and anchovies,” Routhenstein told Fox News Digital.

Many people benefit from eating oily fish more frequently, often three to four times per week, Routhenstein noted. For individuals who do not eat fish regularly, supplements can help raise EPA and DHA to healthier levels.

For those taking omega-3 supplements, dosing should be based on lab results, medications, omega-3 levels and overall medical history, according to Routhenstein. Moderate, quality-controlled supplements are generally considered safe for most people.

There is also some evidence supporting prescription-strength omega-3 products.
“High-dose EPA, such as 4 grams per day of icosapent ethyl, has been shown to reduce major cardiovascular events in certain high-risk populations, while similar doses of mixed EPA/DHA have not consistently shown the same benefit,” Routhenstein said.
Omega-3 dosing should be individualized based on lab data, medication use, current levels and overall medical history. (iStock)
Testing omega-3 levels can also help determine whether intake is adequate. The omega-3 index, a blood test that measures EPA and DHA in red blood cells, is considered one of the most reliable ways to assess status.

“Levels around 8% are associated with lower cardiovascular risk, while levels below approximately 4% are considered low,” Routhenstein said.
Understanding baseline levels can help guide more personalized decisions about diet and supplementation.

Those who are unsure about their omega-3 status or whether supplementation is appropriate should speak with a healthcare provider to determine the best approach.
