What Causes Night Sweats? Understand the Triggers and How to Sleep Better
Waking up drenched in sweat can be unsettling, but what exactly causes night sweats? Also known as nocturnal hyperhidrosis, night sweats go beyond normal temperature regulation and often point to underlying health conditions or lifestyle factors. Let’s explore the common causes of night sweats and practical steps you can take to sleep cooler and more comfortably.
Common Causes of Night Sweats
Fever and Infections
When your body fights infections, it often raises its temperature to create a fever (above 100.4°F or 38°C), which can trigger excessive sweating—even at night—as your body tries to cool down.
Diabetes
Both type 1 and type 2 diabetes can cause night sweats, usually related to low blood sugar (hypoglycemia) that activates the nervous system and increases perspiration. Additionally, nerve damage called autonomic neuropathy can disrupt normal sweat gland function, leading to excessive sweating.
Hormonal Changes
Hormonal shifts are a major factor, especially in women. Perimenopause, menopause, pregnancy, and premenstrual syndrome (PMS) often bring night sweats and hot flashes. Men with low testosterone can also experience similar symptoms, including night sweats, mood changes, and low energy.
Neurological Conditions
Diseases or injuries affecting the nervous system, such as Parkinson’s disease, stroke, or spinal cord injuries, can interfere with your body’s temperature control, resulting in night sweats.
Sleep Disorders
Conditions like obstructive sleep apnea (OSA), where breathing stops briefly during sleep, frequently cause night sweats. Oxygen dips during apnea episodes stimulate sweating as the body reacts to low oxygen levels.
Medication Side Effects
Many medications, including antidepressants (SSRIs), opioids like methadone, hormonal therapies, NSAIDs, and beta blockers, can trigger night sweats. Always consult your doctor before changing any medication.
Cancer and Other Serious Illnesses
Certain cancers (like lymphoma or prostate cancer) and their treatments can cause night sweats. If night sweats are persistent and accompanied by other symptoms like weight loss or fatigue, seek medical advice promptly.
Hyperthyroidism (Overactive Thyroid)
An overactive thyroid speeds up metabolism, raising body temperature and causing sweating, along with symptoms like weight loss, anxiety, and heart palpitations.
Other Factors
Anxiety, PTSD, chronic fatigue syndrome, obesity, acid reflux, caffeine withdrawal, and alcohol or drug use may all contribute to night sweats. Even environmental factors like a warm bedroom, heavy bedding, or tight sleepwear can cause nighttime sweating.
How to Stop Night Sweats and Improve Sleep Quality
Managing night sweats involves lifestyle changes and sometimes medical care. Here are actionable tips to help you sleep cooler and more comfortably:
- Cool your bedroom: Lower the thermostat and use fans or open windows to improve airflow and reduce heat buildup.
- Choose the right mattress and bedding: Opt for cooling mattresses and breathable sheets that wick moisture away.
- Wear breathable sleepwear: Loose, lightweight clothing made from natural fibers can help reduce overheating.
- Avoid triggers: Cut back on caffeine, alcohol, and spicy foods, especially in the evening.
- Maintain a healthy weight: Excess weight can increase sweating and worsen conditions like sleep apnea.
- Practice relaxation: Stress reduction techniques such as yoga or meditation can improve sleep quality and reduce night sweats.
- Review medications: Speak with your doctor if you suspect your medications contribute to night sweats.
Additionally, for those struggling with sleep disruptions related to mouth breathing—which can worsen night sweats and overall sleep quality—using Awesome Mouth Tape can promote nose breathing, leading to deeper, more restful sleep.
When Should You See a Doctor?
If night sweats are frequent, disrupt your sleep, or occur alongside other symptoms like weight loss, fever, or fatigue, it’s important to consult a healthcare professional. Proper diagnosis and treatment can significantly improve your quality of life and address any serious underlying conditions.
