Night sweats are episodes of heavy sweating during sleep that are not caused by the room being too warm or by using too many blankets. In children, they can happen for many reasons, from harmless causes like a cold to more serious medical conditions.
Key facts
Night sweats are fairly common in children. Many children experience them at some point, especially during a mild illness like a cold or flu.
Night sweats can affect children of any age, from babies to teenagers.
Your doctor will ask about your child’s symptoms, sleep habits, and general health. They will also do a physical exam.
The doctor will aim to find the cause of the night sweats. This may take a few visits. They might refer your child to a paediatric specialist if needed.
Treatment depends on the cause. Most children with night sweats due to a mild illness get better on their own. If there is an underlying condition, the doctor will treat that.
For most children, night sweats do not cause long-term problems. You can help by creating a comfortable sleep environment and keeping an eye on other symptoms. If the sweating is from an illness, follow your doctor’s advice for managing the condition.
A healthy diet and regular physical activity help support the immune system. Avoid giving your child heavy meals or sugary drinks right before bed.
Night sweats cannot always be prevented, especially when they are caused by an infection. However, keeping your child’s bedroom cool, not overdressing them at night, and treating illnesses early may help reduce the chance.
Keeping your child up to date with routine vaccinations (like flu, pneumonia, and TB where recommended) can prevent some infections that cause night sweats.
Routine screening is not needed for night sweats alone. Your doctor may recommend tests if symptoms suggest a specific cause.
The outlook is usually good. Most causes of night sweats in children are treatable, and many go away on their own. With proper medical care, most children recover fully and sleep well again.

If an infection is found, the doctor may prescribe antibiotics or other medications. For thyroid problems, medications can help balance hormones. Other causes, like anxiety, may be treated with talking therapies. The doctor will choose the safest option for your child.
Night sweats can sometimes make children feel anxious about sleeping or dry bedding. Reassure your child that it is usually not serious. If your child seems stressed, talk to their doctor or a child psychologist.
