Hormones & Glands
Night Sweats
Episodes of heavy sweating during sleep, most often hormone-related (menopause, thyroid), that can soak bedding and disrupt rest.
Also known as: Nocturnal sweating, Hot flushes at night, Sleep hyperhidrosis, hypoglycemia (definition: low blood sugar)
📝 At a glance
Likely root causes: Menopause and perimenopause — the most common cause in women; declining estrogen disrupts the body's heat-regulation center; Low testosterone in men; Overactive thyroid (hyperthyroidism).
First thing to try: Keep the bedroom cool (65–68°F / 18–20°C), use breathable cotton or linen bedding, and wear lightweight, moisture-wicking sleepwear
See a doctor if: Night sweats that are new, persistent several nights a week, and unexplained
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Menopause and perimenopause — the most common cause in women; declining estrogen disrupts the body's heat-regulation center
- Low testosterone in men
- Overactive thyroid (hyperthyroidism)
- Certain medications — antidepressants, hormone therapies, fever-reducing medicines, steroids
- Low blood sugar (hypoglycemia) at night
- Anxiety and stress, which heighten the nervous system's heat response
- Serious underlying causes in some cases: certain infections (TB), lymphoma (always with weight loss and fever)
Change what you can
- Keep the bedroom cool (65–68°F / 18–20°C), use breathable cotton or linen bedding, and wear lightweight, moisture-wicking sleepwear
- Avoid alcohol, caffeine, spicy food, and large meals close to bedtime — each can trigger a hot flush
- Keep a glass of cool water by the bed to sip during an episode and help the body cool down quickly
- Practice slow, deep breathing at bedtime and when a flush begins — this calms the nervous system and can shorten the episode
- A cool damp cloth on the wrists and forehead during an episode helps the body cool quickly
- If menopause-related, daily outdoor exercise and phytoestrogen-rich foods (whole soy, flaxseed, legumes) can noticeably reduce flush frequency

Simple first step that eases most night sweats.
How to do it ▾
Why it works: Lowering the room temperature and sleeping in light, breathable layers helps the body shed heat steadily through the night rather than in drenching surges.
- Keep the bedroom cool and well-aired; use a fan if needed.
- Choose lightweight, breathable cotton sleepwear and sheets.
- Layer bedding so you can shed covers without fully waking.
- Keep a glass of water and a dry change of nightclothes within reach.

Caution: This manages comfort; it does not address an underlying medical cause.
When to get help: Night sweats with unexplained weight loss, persistent fever, or swollen glands need medical evaluation to rule out infection or other serious causes.

Removes common dietary triggers.
How to do it ▾
Why it works: Alcohol, caffeine, and spicy foods raise body temperature and disrupt the thermostat that governs night sweating; removing them in the evening calms the surges.
- Avoid alcohol in the evening.
- Stop caffeine by early afternoon.
- Skip spicy or very hot foods at the evening meal.
- Keep dinner lighter and earlier.
Ongoing · Every evening
Caution: If sweats persist despite these steps, see a doctor to find the cause.

Traditional herbal option; effect is modest.
How to do it ▾
Why it works: Sage has a traditional and some clinical reputation for reducing excess perspiration; a cup in the day or early evening is the usual form.
- Steep 1 tsp dried sage in a cup of hot water for about 10 minutes.
- Strain and drink, once a day.
- Use for a couple of weeks to judge benefit.
- Combine with a cool room and trigger avoidance.
One cup daily · Once a day, for a few weeks
Caution: Avoid medicinal amounts of sage in pregnancy, breastfeeding, or with seizure disorders. Don't use high-dose sage long-term (thujone content); occasional tea is fine.

🌿 Overview
Night sweats are usually hormone-related — most often menopause in women — but can also signal thyroid problems, medications, or anxiety. A cool bedroom, breathable bedding, avoiding flush triggers, and stress management help most. Persistent night sweats with weight loss or fever need a doctor's check.
Night sweats are episodes of heavy sweating during sleep — enough to drench bedding and wake you up, even in a cool room. Occasional mild night sweating from a warm room or too many blankets is normal, but persistent, drenching night sweats that happen for no obvious reason are worth taking seriously. The most common cause in women is the hormonal shift of perimenopause and menopause — the brain's temperature-regulating center responds to dropping estrogen by triggering sudden bursts of heat and sweating. In men, low testosterone can cause a similar response. But night sweats also occur with thyroid overactivity, certain medications (especially antidepressants and hormone drugs), low blood sugar at night, and anxiety. Less commonly, persistent night sweats alongside unexplained weight loss and fever can signal a serious underlying illness. When night sweats are new, persistent, or come alongside other unexplained symptoms, see a doctor to rule out any underlying cause. Once addressed, cooling habits, dietary adjustments, and stress relief bring real relief for most people.
Common signs
- Heavy sweating during sleep that soaks clothing or bedding

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Cooling, plant-based whole foods: vegetables, fruits, whole grains, legumes
- Flaxseed and whole soy foods — plant estrogens (phytoestrogens) that may ease menopause flushes
- Magnesium-rich foods: leafy greens, nuts, seeds — magnesium supports sleep and can ease night sweating
- Plenty of water through the day to stay well hydrated
Go easy on
- Alcohol — a potent hot-flush trigger, especially red wine
- Caffeine in the afternoon and evening
- Spicy food and hot drinks close to bedtime
- Excess sugar and refined carbohydrates
A clean, plant-rich diet with plenty of magnesium and phytoestrogen-containing foods — flaxseed, edamame, tempeh — is the most consistently helpful dietary change for hormone-related night sweats.
⚖️ Good to know
- Night sweats with unexplained weight loss, persistent fever, or swollen lymph nodes need prompt medical evaluation.
- Do not assume menopause is the cause without a doctor's check — especially in men or young women.
- Some medications cause night sweats as a side effect; discuss this with your prescriber before stopping any medicine.
