Understanding and Managing Night Sweats

Imagine waking up in the dead of the night, soaked in sweat. If this is a frequent occurrence, you might be experiencing what's commonly known as “night sweats.”

While occasional sweating during sleep can be due to environmental factors, persistent night sweats often indicate a deeper issue. 

To help you navigate through this, we have gathered comprehensive information from authoritative health organizations like the Mayo Clinic, the Cleveland Clinic, the Sleep Foundation, and the International Hyperhidrosis Society, covering common causes, identifying symptoms, and providing practical solutions to manage night sweats.

What Are Night Sweats?

Night sweats or sleep hyperhidrosis, characterized by excessive sweating during sleep, are not simply a byproduct of a hot bedroom or heavy pajamas. According to the Mayo Clinic, true night sweats are severe hot flashes occurring at night that can drench your sleepwear and sheets, unrelated to an overheated environment.

Why Do Night Sweats Occur?

Night sweats can be linked to several causes, including medical conditions and lifestyle factors.

  • Menopause Symptoms: The hormonal fluctuations associated with menopause often lead to hot flashes and night sweats. The Cleveland Clinic identifies menopause as one of the most common causes of night sweats in women.
  • Sleep Disorders: Sleep disorders such as obstructive sleep apnea can cause night sweats. The National Sleep Foundation states that the effort it takes to breathe with this condition can lead to excessive sweating.
  • Hyperthyroidism: An overactive thyroid gland (hyperthyroidism) can stimulate an increased metabolic rate, leading to elevated body temperature and excessive sweating, as explained by the International Hyperhidrosis Society.
  • Certain Medical Conditions: According to the Mayo Clinic, specific medical conditions, including certain types of cancers, hypoglycemia (low blood sugar), GERD (gastroesophageal reflux disease, or acid reflux), and certain infections, can trigger night sweats.
  • Medications: Some medications, such as certain antidepressants, diabetes medication, hormone therapy drugs, can also lead to night sweats.

Symptoms: More Than Just Sweating

In addition to excessive sweating during sleep, there are a few other symptoms associated with night sweats:

  • Excessive Sweating: Waking up with soaked clothes and sheets is the primary symptom of night sweats.
  • Hot Flashes: As stated by the National Institute of Health, you may experience sudden, intense feelings of warmth spreading over the body, typically affecting the face, neck, and chest.
  • Irregular Sleep: Night sweats often lead to fragmented sleep, causing frequent waking and making it difficult to fall back asleep.
  • Associated Symptoms: Depending on the underlying cause, other symptoms such as unexplained weight loss, localized pain, or fever may be present.

Managing Night Sweats: Practical Tips and Medical Interventions

Dealing with night sweats can be a challenging task. Here are some strategies from our team of experts, as well as insights from the Mayo Clinic and the Sleep Foundation:

  • Cool Sleep Environment: Keeping your bedroom at a cooler temperature can help reduce night sweating. Adjust your room's temperature and consider investing in a fan or air conditioner.
  • Light and Breathable Sleepwear: Opt for lightweight, breathable fabrics for sleepwear and bed linen to help regulate your body temperature and decrease sweat production.
  • Dietary Modifications: Certain foods and beverages can exacerbate night sweats. Try to avoid known triggers such as spicy foods, caffeine, and alcohol, especially close to bedtime.
  • Regular Physical Activity: Engaging in regular physical activity can help regulate your hormones and manage your weight, potentially reducing night sweats.
  • Medical Therapies: Depending on the cause of your night sweats, specific treatments can be helpful. For instance, for women going through menopause, hormone replacement therapy might be recommended by their healthcare provider.

If your night sweats persist despite making these changes, it's essential to consult your healthcare provider. They can investigate potential underlying conditions and provide appropriate treatment recommendations.


The journey to understanding and dealing with night sweats can be a complicated one. But remember, with the right knowledge, support, and treatment from your healthcare provider, you can effectively manage this condition. Whether it involves modifying your lifestyle, changing your diet, or exploring medical treatments, always remember: there's help available, and you are not alone in this journey.
