What are night sweats?
Night sweats, medically known as sleep hyperhidrosis, refer to episodes of excessive sweating during sleep. They are characterized by intense sweating that can soak your sleepwear and bedding, often requiring you to change your clothes or bedding multiple times during the night. Night sweats are different from the normal sweating that occurs during the day or in response to physical activity or hot weather.
Night sweats can be quite bothersome and disruptive to sleep, leading to feelings of discomfort and fatigue. They may be accompanied by other symptoms such as hot flashes, rapid heartbeat, chills, or a feeling of warmth. Night sweats can occur in both men and women, but they are more commonly associated with menopause in women.
There are various potential causes of night sweats, including:
● Menopause:
Hormonal changes during menopause can lead to night sweats and hot flashes in women.
● Infections:
Certain infections, such as tuberculosis, endocarditis (infection of the heart valves), or HIV/AIDS, can cause night sweats.
● Hormonal disorders:
Conditions like hyperthyroidism (overactive thyroid) or pheochromocytoma (a tumor of the adrenal glands) can result in excessive sweating, including night sweats.
● Certain medications:
Some medications, such as antidepressants, hormone therapy drugs, or medications that lower fever (antipyretics), may cause night sweats as a side effect.
● Sleep disorders:
Night sweats can be associated with sleep disorders like obstructive sleep apnea.
● Anxiety and stress:
Emotional factors can trigger excessive sweating, including during sleep.
● Certain cancers:
Night sweats can be a symptom of certain cancers, such as lymphoma.
If you are experiencing frequent or severe night sweats, it is recommended to consult a healthcare professional for a proper evaluation. They can help determine the underlying cause and provide appropriate treatment or management strategies.
What causes night sweats in women?
Night sweats in women can be caused by various factors, and the most common cause is hormonal changes associated with menopause. During menopause, a woman's body undergoes significant hormonal fluctuations, particularly a decrease in estrogen levels. These hormonal changes can disrupt the body's temperature regulation, leading to hot flashes and night sweats.
However, there are other potential causes of night sweats in women that should be considered as well, including:
■ Hormonal disorders:
Conditions such as hyperthyroidism (overactive thyroid) or pheochromocytoma (a tumor of the adrenal glands) can cause night sweats.
■ Medications:
Certain medications, such as hormone therapy drugs, antidepressants, or medications that lower fever (antipyretics), may lead to night sweats as a side effect.
■ Infections:
Infections like tuberculosis or HIV/AIDS can cause night sweats.
■ Sleep disorders:
Night sweats can be associated with sleep disorders like obstructive sleep apnea.
■ Stress and anxiety:
Emotional factors can trigger excessive sweating, including during sleep.
■ Certain cancers:
Night sweats can be a symptom of certain cancers, such as lymphoma.
It's important to consult a healthcare professional if you are experiencing frequent or severe night sweats. They can evaluate your symptoms, conduct necessary tests, and provide appropriate diagnosis and treatment options based on your specific situation.
Premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD)
Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are two distinct conditions that affect some women before their menstrual period. They are characterized by a range of physical, emotional, and behavioral symptoms that occur in the days or weeks leading up to menstruation.
● Premenstrual Syndrome (PMS):
PMS refers to a collection of symptoms that occur in the luteal phase of the menstrual cycle, typically in the week or two before menstruation begins. Common symptoms of PMS include:
• Mood swings
• Irritability
• Fatigue
• Breast tenderness
• Bloating
• Food cravings
• Headaches
• Changes in sleep patterns
• Anxiety or depression
The severity of PMS symptoms can vary widely among individuals, and they typically subside shortly after the start of menstruation.
● Premenstrual Dysphoric Disorder (PMDD):
PMDD is a more severe form of premenstrual syndrome that affects a smaller percentage of women. It involves intense emotional and physical symptoms that significantly impact a woman's quality of life. Some symptoms of PMDD include:
• Severe mood swings
• Extreme irritability or anger
• Depression or feelings of hopelessness
• Anxiety or tension
• Fatigue or lack of energy
• Difficulty concentrating
• Changes in appetite or food cravings
• Sleep disturbances
• Physical symptoms like breast tenderness, bloating, or headaches
PMDD symptoms typically occur in the week prior to menstruation and significantly improve or disappear with the onset of menstruation.
The exact causes of PMS and PMDD are not fully understood, but hormonal changes during the menstrual cycle are believed to play a role. The fluctuations in estrogen and progesterone levels, as well as serotonin imbalances in the brain, are thought to contribute to the development of these conditions.
If PMS or PMDD symptoms significantly interfere with daily functioning or quality of life, it is advisable to consult a healthcare professional. They can help diagnose the condition, rule out other possible causes, and recommend appropriate management options, which may include lifestyle changes, medications, or psychotherapy.
Are menopause, perimenopause, PMS/PMDD and pregnancy the only causes of night sweats?
No, menopause, perimenopause, PMS/PMDD, and pregnancy are not the only causes of night sweats. While these are common factors associated with night sweats in women, there are several other potential causes to consider. Here are some additional causes of night sweats:
■ Infections:
Certain infections can cause night sweats, such as tuberculosis, endocarditis (infection of the heart valves), HIV/AIDS, and certain types of abscesses.
■ Hormonal disorders:
Apart from menopause and perimenopause, other hormonal disorders like hyperthyroidism (overactive thyroid) or pheochromocytoma (a tumor of the adrenal glands) can cause night sweats.
■ Medications:
Some medications, such as antidepressants, hormone therapy drugs, or medications that lower fever (antipyretics), can have night sweats listed as a side effect.
■ Sleep disorders:
Night sweats can be associated with sleep disorders like obstructive sleep apnea or night sweats due to excessive body heat during sleep.
■ Anxiety and stress:
Emotional factors, including anxiety and stress, can trigger excessive sweating, including during sleep.
■ Certain cancers:
Night sweats can be a symptom of certain cancers, such as lymphoma, leukemia, or carcinoid tumors.
■ Medication or drug withdrawal:
Withdrawal from certain medications or drugs, such as opioids, can sometimes cause night sweats as a temporary symptom.
■ Other medical conditions:
Various medical conditions like gastroesophageal reflux disease (GERD), chronic fatigue syndrome, autonomic neuropathy, and certain autoimmune diseases can occasionally lead to night sweats.
It's important to note that this list is not exhaustive, and there may be other causes of night sweats. If you are experiencing frequent or severe night sweats, it is recommended to consult a healthcare professional for a proper evaluation and diagnosis to determine the underlying cause in your specific situation.
How are menopause-related night sweats treated?
Menopause-related night sweats can be managed through various treatment approaches. The choice of treatment depends on the severity of symptoms and individual preferences. Here are some common strategies used to alleviate menopause-related night sweats:

Remember, these guidelines are not meant to replace professional medical advice. If you have concerns about your night sweats, it is always best to consult a healthcare professional who can evaluate your symptoms, take your medical history, and conduct any necessary tests to determine the underlying cause and provide appropriate guidance and treatment.
Do menopause-related night sweats ever end?
Yes, menopause-related night sweats typically do end over time. Night sweats are a common symptom during the menopausal transition and are primarily caused by hormonal fluctuations, particularly a decrease in estrogen levels. As women progress through menopause and their hormone levels stabilize, the frequency and intensity of night sweats tend to decrease.
The duration of night sweats can vary among women. For some women, night sweats may last for a few months to a couple of years, while for others, they may persist for a longer period. On average, night sweats associated with menopause usually resolve within a few years after the onset of menopause.
It's important to note that the menopausal transition can be different for every woman, and the duration of symptoms can vary. Some women may experience night sweats for a shorter duration, while others may find relief from them earlier or later in the transition. Additionally, other factors such as overall health, lifestyle, and genetics can influence the duration and severity of menopausal symptoms.
If you are experiencing prolonged or severe night sweats that significantly impact your quality of life, it is recommended to consult a healthcare professional. They can evaluate your specific situation, provide guidance, and discuss potential treatment options to manage your symptoms during the menopausal transition.
Can stress cause night sweats?
Yes, stress can be a contributing factor to night sweats. Emotional stress and anxiety can trigger excessive sweating, including during sleep. When you experience stress, your body's stress response system activates, which can lead to physiological changes, including increased heart rate, elevated body temperature, and sweating.
Stress activates the sympathetic nervous system, leading to the release of stress hormones like adrenaline and cortisol. These hormonal changes can affect your body's temperature regulation, potentially leading to night sweats. Additionally, stress and anxiety can disrupt sleep patterns, which may further contribute to night sweats.
It's important to note that while stress can cause night sweats, it is often just one contributing factor among others. Night sweats can have various causes, including hormonal changes, medications, infections, and underlying medical conditions. If you are experiencing frequent or severe night sweats and suspect stress as a potential trigger, it may be helpful to address stress management techniques such as relaxation exercises, mindfulness practices, regular exercise, and seeking support from healthcare professionals or therapists.
If night sweats persist or significantly interfere with your daily life, it's advisable to consult a healthcare professional for a comprehensive evaluation. They can help identify the underlying cause of your night sweats and recommend appropriate management strategies.
What cancers cause night sweats?
Night sweats can be associated with certain types of cancers. While night sweats alone are not specific to cancer and can have various causes, including non-cancerous conditions, they can sometimes be a symptom of an underlying malignancy. Here are some cancers that have been known to be associated with night sweats:
■ Lymphoma:
Night sweats are commonly associated with lymphomas, particularly Hodgkin lymphoma and some types of non-Hodgkin lymphoma. Night sweats in lymphoma are often described as drenching, severe, and recurrent.
■ Leukemia:
Certain types of leukemia, such as chronic myeloid leukemia (CML) or acute lymphoblastic leukemia (ALL), can sometimes cause night sweats as a symptom.
■ Carcinoid Tumors:
These rare tumors can produce hormones that cause a range of symptoms, including night sweats. Carcinoid tumors most commonly develop in the gastrointestinal tract or lungs.
