Night Sweats: Why They Happen and How to Find Relief

If you wake up drenched in sweat more than once a week, you’ve probably wondered what’s going on. Night sweats are just heavy sweating while you sleep, and they can mess with your rest, mood, and confidence. The good news is most of the time you can pinpoint a cause and take steps to feel cooler again.

Common Triggers You Can Spot

First off, think about what’s changed in your life. A hot bedroom, heavy blankets, or even a new pillow can raise your core temperature. Hormonal shifts are another big player – menopause, thyroid issues, and low testosterone often show up as night sweats. Certain meds, especially antidepressants, blood pressure pills, and fever‑reducers, have sweating listed as a side effect.

Infections that cause fevers (like the flu or TB) can also make you sweat at night. If you’ve been under a lot of stress lately, your body releases cortisol, which sometimes tricks it into overheating. Finally, lifestyle habits such as drinking alcohol before bed or eating spicy foods late in the evening add extra heat.

Quick Tips for a Cooler Night

Start with the bedroom itself. Keep the room around 65–70°F (18‑21°C) and use a fan or open a window if you can. Choose breathable fabrics – cotton sheets, moisture‑wicking pajamas, and light blankets are better than flannel or polyester.

Stay hydrated throughout the day; water helps your body regulate temperature. Avoid caffeine, alcohol, and big meals at least two hours before bedtime because they raise metabolism and trigger sweating.

If you suspect a medication is the culprit, talk to your pharmacist or doctor about alternatives or dosage adjustments. Some people find that adding a low‑dose melatonin supplement helps reset their sleep cycle and reduces sweating spikes.

When stress feels like a constant companion, try simple relaxation tricks: deep breathing, a short meditation session, or gentle stretching before you hit the sheets. These practices calm your nervous system and can lower night‑time heat production.

Even with these changes, keep an eye on any red flags. Persistent night sweats that come with weight loss, fever, unexplained pain, or blood in sweat deserve a medical check‑up. Conditions like lymphoma, diabetes, and chronic infections sometimes hide behind sweaty nights.

If you notice a pattern—say, sweats only during certain phases of your menstrual cycle or after starting a new drug—write it down. A clear record helps your doctor narrow down the cause faster.

Bottom line: night sweats are rarely a mystery. By tweaking your environment, watching what you eat and drink, and noting any medication side effects, you can often bring the temperature back to normal. When the sweating sticks around despite those tweaks, schedule a visit with a healthcare professional to rule out deeper issues. Sleep better, stay dry, and take control of those night sweats.
