Why Does My Partner Sweat Profusely While Sleeping?

Why do we sweat profusely while sleeping?

Dear Dr.
Hong: I personally feel neither particularly stuffy nor hot, just comfortable.
However, my husband, who sleeps next to me, wakes up drenched in sweat (on his chest and back), and the sheets and comforter are also significantly wet, which seems to happen more often than occasionally.
1.
Older generations say this is "cold sweat," which is a bad sign.
Is this true? 2.
What kind of "physical conditions" or "constitutions" might lead to this possibility? 3.
Are there any methods for improvement? Thank you!

Hello~ 1.
"Cold sweating" is a colloquial term in traditional folklore, and there is no detailed medical definition for it.
2.
Sweating can be classified as generalized or localized: (1) Generalized sweating is associated with the following conditions: autonomic nervous system disorders, metabolic diseases (such as thyroid disorders, glucose regulation abnormalities, menopause, gout, etc.), medication use (such as antidepressants, beta-blockers, etc.), chronic alcohol dependence, and pulmonary tuberculosis.
3.
Treatment methods: (1) Topical agents: alter the stratum corneum to reduce sweat gland secretion (consult a dermatologist).
(2) Oral medications: anticholinergic agents.
(3) Surgery: sympathectomy targeting areas of localized sweating.

More Info

Experiencing excessive sweating during sleep, known as night sweats, can be concerning for both the individual affected and their partner. There are several potential reasons why your husband might be sweating profusely while sleeping, and understanding these can help you address the issue effectively.

1. Understanding Night Sweats: Night sweats are defined as excessive sweating during sleep that can soak through clothing and bedding. While it can be alarming, it is important to note that night sweats are not always indicative of a serious health issue. They can occur due to a variety of factors, including environmental conditions, lifestyle choices, and underlying medical conditions.

2. Common Causes:
- Environmental Factors: The temperature of the bedroom, the type of bedding used, and even the pajamas worn can contribute to night sweats. If the room is too warm or if heavy blankets are used, this can lead to excessive sweating.

- Hormonal Changes: Hormonal fluctuations, particularly in men, can lead to night sweats. Conditions such as hyperhidrosis (excessive sweating) or hormonal imbalances can be culprits.

- Medical Conditions: Certain medical conditions can cause night sweats, including infections (like tuberculosis), autoimmune disorders, and malignancies (such as lymphoma). Additionally, conditions like sleep apnea can also lead to increased sweating during sleep.

- Medications: Some medications, particularly antidepressants, hormone therapies, and medications for diabetes, can have side effects that include night sweats.

3. Cultural Beliefs: The belief that night sweats are a sign of "cold sweats" or a bad omen is a common cultural notion. However, from a medical standpoint, while night sweats can be a symptom of underlying health issues, they are not inherently "bad." It is essential to differentiate between occasional night sweats and persistent ones that may warrant further investigation.

4. Who is Affected?: Night sweats can affect anyone, but they are more common in individuals with certain health conditions, those undergoing significant stress, or those with a family history of hyperhidrosis. Additionally, lifestyle factors such as alcohol consumption, smoking, and obesity can increase the likelihood of experiencing night sweats.

5. Improvement Strategies:
- Adjust the Environment: Ensure that the bedroom is well-ventilated and kept at a comfortable temperature. Consider using lighter bedding and moisture-wicking sleepwear.

- Lifestyle Modifications: Encourage your partner to maintain a healthy weight, reduce alcohol intake, and quit smoking if applicable. Regular exercise can also help regulate body temperature.

- Consult a Healthcare Professional: If night sweats persist or are accompanied by other concerning symptoms (such as weight loss, fever, or fatigue), it is crucial to consult a healthcare provider. They may recommend tests to rule out underlying conditions or adjust medications if necessary.

In conclusion, while night sweats can be a nuisance and may indicate an underlying issue, they are often manageable through environmental adjustments and lifestyle changes. If the problem persists, seeking medical advice is the best course of action to ensure your partner's health and well-being.
