Excessive Sweating at Night: Causes and Solutions

Everyone sweats during gut-wrenching moments like interviewing for a new job or speaking before a crowd. But if you experience excessive sweating at night, a deeper issue might be to blame.

Night sweats are incidents of excessive perspiration that happen while you sleep. Sweating while sleeping can drench your clothes and even your bedding, often requiring you to change your pajamas or sheets before morning. In a word, night sweats are miserable.

So what separates sweating in sleep from normal sweating, and what can you do about it? Today we’ll learn more about how to stop night sweats and wake feeling rested.

SWEATING WHILE SLEEPING? HERE’S WHY

How much you sweat depends on your DNA, medical conditions, stress and other factors. However, you might sweat more than others at night — regardless of temperature.

Here are a few reasons you might be sweating while sleeping.

1. HYPERHIDROSIS

It’s normal to experience night sweats when you’re sick or sleeping in hot weather, but some people sweat for no reason, at any time.

People with hyperhidrosis experience excessive sweating that’s unrelated to climate or other external circumstances. The underarms, forehead, hands and feet are the areas most commonly affected.

However, people with secondary hyperhidrosis (or diaphoresis) sweat due to an underlying condition. A telltale sign of secondary hyperhidrosis is excessive sweating all over, not just one specific area. You’re more likely to sweat while sleeping if you have secondary hyperhidrosis.

2. MEDICAL CONDITIONS

If you’ve recently been diagnosed with one of the following conditions, excessive sweating at night might be a side effect. The most effective way to stop medically-induced night sweats is to treat the underlying illness.

  • Menopause and pregnancy
  • Infections
  • Cancer
  • Hyperthyroidism
  • Hormone disorders
  • Neurologic conditions
  • Alcoholism

If addressing the illness or condition doesn’t eliminate your night sweats, consult your doctor about other possible solutions. Dermira and TheraVida manufacture treatments for secondary hyperhidrosis, though the long-term effects are still unknown.

3. MEDICATIONS

If you constantly sweat at night, it could be a side effect of a prescription drug. Common drugs attributed to secondary hyperhidrosis include:

  • Antidepressants
  • Pain medications, aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Blood pressure medications
  • Cancer treatments
  • Oral diabetes drugs and insulin
  • Antibiotics
  • Hormone treatments
  • Dietary supplements like zinc and iron.

If you suspect one of these medications is causing your night sweats, consult your doctor. Forgoing certain medications you rely upon could pose more significant health risks than sweating at night. It’s always wise to talk to your doctor before making any health-related decisions.

HOW TO STOP NIGHT SWEATS

Treating medical conditions can take time. But there are other lifestyle changes you can make today to stop sweating at night, including wearing cooling clothing or using sweat-wicking sleep products.

5. KEEP THE ROOM COOL

For optimal sleep, keep your bedroom temperature between 60 and 67 degrees Fahrenheit. While room temperature doesn’t cause sweating in sleep, it may make you feel worse. Lowering your thermostat keeps heat from building up around you during the night.

6. AVOID SWEAT-INDUCING FOODS BEFORE BED

Alcohol and caffeinated beverages increase your heart rate, blood pressure and body temperature, triggering a sweat response.

Hot and spicy foods stimulate nerve receptors in your mouth, tricking your body into thinking it’s hot. The not-so-surprising result? Sweat.

Avoiding sweat-inducing foods, especially in the evening, may reduce excessive sweating at night. Conversely, try adding sweat reducing foods into your diet.

7. REDUCE STRESS

Stress and a lack of exercise are other contributors to night sweats. Take proactive steps to reduce stress and work regular exercise into your routine to reduce excessive sweating at night.
