Cold sweats happen when your body produces a clammy, chilled sweat without physical exertion or heat exposure. Getting rid of them depends entirely on what’s triggering them, because cold sweats are a symptom, not a condition on their own. The fix can be as simple as slowing your breathing during a panic attack, eating something when your blood sugar drops, or making changes to your sleep environment. In some cases, though, cold sweats signal something more serious that needs medical attention.
Why Cold Sweats Happen
Unlike regular sweating, which cools you down during exercise or hot weather, cold sweats are driven by your nervous system’s fight-or-flight response. Your body releases adrenaline, which raises your blood pressure, redirects blood flow to your vital organs, and activates your sweat glands all at once. The result is that damp, clammy feeling on cool skin.
This response can be triggered by a wide range of things. The most common culprits fall into a few categories:
- Low blood sugar (hypoglycemia): Especially common in people with diabetes who use insulin. Along with cold sweats, you may feel dizzy, confused, weak, or nauseous.
- Stress, anxiety, and panic attacks: Your fight-or-flight system fires up even when there’s no physical danger. Panic attacks can mimic heart attack symptoms, including sweating, chest pain, and nausea.
- Infections and fever: Viruses like the flu and COVID-19 raise your body temperature. As the fever breaks and your temperature drops, cold sweats often follow. More serious infections like sepsis can also cause them.
- Hormonal changes: Menopause and perimenopause commonly cause hot flashes followed by cold sweats as your body overcorrects its temperature. Some women experience more cold chills than hot flashes.
- Pain and shock: Severe pain triggers adrenaline release, producing cold sweats. If the sweating is accompanied by rapid breathing, pale skin, and dizziness, it can indicate shock, which is a medical emergency.
- Heart problems: Cold sweats can be a sign of coronary artery disease or even a heart attack. Some heart attacks are “silent,” presenting with sweating and shortness of breath rather than dramatic chest pain.
- Medications: Certain drugs, including hormone therapies and medications used to manage blood sugar, can trigger sweating as a side effect. An overactive thyroid, whether caused by medication or a gland disorder, speeds up your metabolism and increases sweating.
Immediate Steps to Stop Cold Sweats
When cold sweats hit, the fastest way to feel better depends on recognizing what set them off. But a few strategies help across the board.
Start with slow, deep breathing. Inhale for four counts, hold briefly, and exhale for six counts. This directly counteracts the fight-or-flight response by signaling your nervous system to calm down. It works whether the trigger is anxiety, pain, or a hot flash. If you suspect low blood sugar, eat or drink something with fast-acting carbohydrates: juice, glucose tablets, or a few crackers. You should start feeling better within 10 to 15 minutes.
Drink cold water. Sipping ice water helps regulate your core temperature and prevents dehydration, which can make cold sweats worse on its own. If you’re recovering from a fever, keep fluids close by throughout the day. Layer your clothing so you can remove a layer when sweating starts and add one back when the chill follows. Lightweight, breathable fabrics give your body the best chance to regulate itself.
Managing Stress-Related Cold Sweats
If anxiety or panic attacks are behind your cold sweats, the most effective long-term approach is addressing the anxiety itself. Deep breathing, meditation, and yoga all help reduce baseline stress levels, making episodes less frequent over time. These aren’t just generic wellness tips: they directly lower the nervous system activation that produces cold sweats in the first place.
Grounding techniques can interrupt a cold sweat mid-episode. Focus on five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste. This pulls your brain out of the threat-response loop and back into the present moment, which slows adrenaline production. Regular physical activity also helps calibrate your stress response so it doesn’t fire as easily.
Treating Hormone-Related Cold Sweats
For cold sweats tied to menopause or perimenopause, the first step is tracking your triggers. Keep a simple log of when episodes happen and what preceded them. Common triggers include spicy foods, alcohol, caffeine, emotional stress, and warm environments. Avoiding or reducing these can cut the frequency of episodes significantly.
Hormone therapy is the most direct medical treatment. For women still having periods, low-dose hormonal birth control can help. For those past menopause, menopausal hormone therapy relieves hot flashes and the cold sweats that follow them. The general guidance is to use the lowest effective dose for the shortest time needed. If hormone therapy isn’t an option, certain antidepressants, blood pressure medications, and epilepsy drugs have been found to reduce hot flashes even in people who don’t have those conditions.
Practical measures make a real difference too. Keep a fan running at night and at your desk. Dress in layers you can peel off quickly. Have ice water within reach. Losing weight can also help, since hot flashes and cold sweats tend to be more severe in people carrying extra weight.
Better Sleep When Cold Sweats Hit at Night
Nighttime cold sweats are particularly disruptive because they wake you up damp and chilled, and falling back asleep in wet sheets is miserable. Your bedding choices can make a significant difference.
Swap standard cotton sheets for moisture-wicking fabrics designed to pull sweat away from your skin and dry quickly. These use the same materials found in athletic clothing and are specifically marketed for night sweats. Layer your bedding so you can kick off a blanket during a sweat and pull it back when the chill sets in, rather than being stuck with one heavy comforter. For pajamas, look for moisture-wicking long underwear or lightweight exercise clothing made of breathable synthetic blends. Avoid non-breathable synthetics like standard polyester, which trap heat and moisture against your skin.
Bed climate control systems, which circulate cool or warm water through a mattress pad, are another option. They let you adjust your sleep surface temperature throughout the night without changing the room thermostat, which is especially useful if you share a bed with someone who sleeps at a different temperature.
When Cold Sweats Are an Emergency
Most cold sweats are uncomfortable but not dangerous. However, certain combinations of symptoms require immediate medical attention. Cold sweats paired with chest pain or pressure, especially if the pain radiates to your arm or jaw, can indicate a heart attack. Cold sweats with rapid breathing, a racing heart rate, pale or ashen skin, and confusion can signal shock.
Call 911 if cold sweats come on suddenly and are accompanied by any of the following: chest pain or tightness, nausea or vomiting, fainting or near-fainting, difficulty speaking, or bluish discoloration of the lips or fingertips. These symptoms can indicate that your organs aren’t getting enough blood, and minutes matter.
For cold sweats that keep coming back without an obvious cause, or that are getting worse over time, a medical workup can check for underlying conditions like thyroid disorders, rare adrenal gland tumors, or undiagnosed infections. Blood tests and a physical exam are typically enough to narrow down the cause and guide treatment.
