When to seek care for night sweats

Overview

Night sweats are episodes of heavy sweating that happen while you sleep, often soaking your clothes and sheets. They can be caused by many different things, ranging from harmless to serious.

Yes, night sweats are relatively common. Many people experience them at some point in their lives.

Night sweats can affect anyone, but they are more common in women during menopause, people taking certain medications, and those with infections or other medical conditions.

Symptoms

Common symptoms

• Waking up with your pajamas or bed sheets soaked in sweat
• Sweating that forces you to change clothes or bedding during the night
• Feeling hot and clammy while sleeping

Symptoms in children

• Night sweats in children can be normal, especially during growth spurts or mild illnesses.
• They may also be a sign of conditions like sleep apnea, anxiety, or an infection.

Symptoms in older adults

• Night sweats in older adults are more likely to be linked to medication side effects, chronic infections, or serious conditions like cancer.
• It's important to see a doctor if they persist.

Causes

Main causes

• Infections such as tuberculosis, HIV, or endocarditis (inflammation of the heart lining)
• Hormonal changes, like those during menopause or an overactive thyroid
• Side effects of certain medications, including some antidepressants and hormone therapies
• Anxiety or high stress levels
• Cancers such as lymphoma (a type of blood cancer) – though this is rare

Risk factors

• Being a woman in perimenopause or menopause
• Having a chronic illness or infection
• Taking medications that can cause sweating as a side effect
• Having a family history of certain cancers

When to see a doctor

See a doctor urgently if:

• See a doctor urgently (within a few days) if night sweats come with fever, weight loss, or persistent cough.
• Also seek urgent care if you have night sweats and a known illness like cancer or HIV.

Book a routine appointment if:

• Make a routine appointment if night sweats are occasional and you have no other concerning symptoms.
• Also schedule a visit if night sweats are linked to menopause and you want to discuss management options.

Diagnosis

Your doctor will ask about your symptoms, medical history, and any medications you take. They may also perform a physical examination to check for signs of infection or other issues.

Tests that may be done

• Blood tests to check for infections, hormone levels, or signs of inflammation
• Chest X-ray or CT scan if the doctor suspects a lung infection or cancer
• Thyroid function tests to check for an overactive thyroid

What to expect at your appointment

The doctor will try to find the underlying cause. This may take a few visits and tests. They will explain each step and what the results mean.

Treatment

Treatment for night sweats focuses on the cause. It may include managing an infection, adjusting medications, or making lifestyle changes.

Self-care at home

• Keep your bedroom cool and well-ventilated (e.g., use a fan or open a window)
• Use lightweight, moisture-wicking pajamas and sheets
• Avoid spicy foods, caffeine, and alcohol in the evening
• Practice relaxation techniques like deep breathing or meditation to reduce stress

Medical treatments

Depending on the cause, your doctor may recommend antibiotics or antivirals for infections, hormone therapy for hormonal changes, or adjustments to your current medications. Never change or stop a medication without your doctor's advice.

When is surgery considered?

Surgery is rarely needed for night sweats themselves. However, it may be necessary to treat an underlying cause, such as removing a tumor or abscess.

Living with this condition

Night sweats can be disruptive, but you can manage them by keeping a towel and change of clothes by your bed, washing bedding more often, and staying hydrated.

Lifestyle tips

• Stay hydrated throughout the day with water
• Exercise regularly to improve overall health and reduce stress
• Keep a sleep diary to track when night sweats happen and any triggers

Diet and exercise

A balanced diet and regular physical activity can help manage weight, stress, and hormones, which may reduce night sweats.

Mental health and emotional wellbeing

Night sweats can cause worry about your health and disturb your sleep, leading to fatigue or anxiety. It's normal to feel concerned, but remember that most causes are treatable.

Prevention

Not always, but you can lower your risk by managing stress, maintaining a healthy weight, and treating underlying conditions early.

Complications

If left untreated

• If the underlying cause is serious (like an infection or cancer), it could worsen without treatment.
• Chronic night sweats can lead to dehydration, sleep deprivation, and fatigue.

Long-term outlook

The outlook is generally very good. Most causes of night sweats are treatable or manageable. With proper medical care, night sweats often improve or go away completely.
