Seeing your little one all sweaty while they sleep can be a cause for concern. But before you start worrying, it’s important to understand that baby sweating in sleep is quite common and usually harmless. In this article, we’ll explore the various causes of baby sweating in sleep and when it’s necessary to consult a doctor.

1. Overdressing

One of the most common reasons for baby sweating in sleep is overdressing. Babies have a smaller body surface area compared to adults, which means they can easily get overheated if they’re wearing too many layers or heavy clothing.

2. Room Temperature

The room temperature can also play a role in causing baby sweating in sleep. If the room is too warm or poorly ventilated, it can make your baby sweat excessively.

3. Fever

A fever is another common cause of baby sweating. When your little one has a fever, their body temperature rises, causing them to sweat as a way to cool down.

4. Nightmares or Night Terrors

Just like adults, babies can also experience nightmares or night terrors. These can cause increased heart rate and sweating during sleep.

5. Sleep Apnea

Sleep apnea is a condition where a baby’s breathing is temporarily interrupted during sleep. This can lead to increased sweating as the body tries to compensate for the lack of oxygen.

6. Gastroesophageal Reflux (GERD)

GERD is a common condition in babies where stomach acid flows back into the esophagus, causing discomfort. This discomfort can lead to sweating during sleep.

7. Infections

Infections, such as respiratory infections or urinary tract infections, can cause fever and sweating in babies. If your baby’s sweating is accompanied by other symptoms like coughing or difficulty breathing, it’s important to consult a doctor.

8. Hyperthyroidism

Although rare, hyperthyroidism can occur in babies and cause excessive sweating. If you notice other symptoms like weight loss or irritability, it’s important to seek medical advice.

9. Caffeine Intake

If you’re breastfeeding and consuming caffeine, it can sometimes affect your baby’s sleep and cause sweating. Consider reducing your caffeine intake and see if it makes a difference.

10. Medications

Certain medications can also cause sweating as a side effect. If your baby has recently started a new medication and you notice excessive sweating, consult your doctor.

11. Teething

Teething can cause discomfort and increased saliva production in babies, which can lead to sweating during sleep. This is usually temporary and not a cause for concern.

12. Anxiety or Stress

Believe it or not, babies can experience anxiety or stress, which can manifest as sweating during sleep. Creating a calm and soothing sleep environment can help alleviate these symptoms.

13. Underlying Medical Conditions

In some cases, baby sweating in sleep can be a symptom of an underlying medical condition. If your baby’s sweating is persistent, accompanied by other concerning symptoms, or if you have any doubts, it’s always best to consult a doctor.

When to Consult a Doctor

While baby sweating in sleep is usually harmless, there are certain instances where it’s important to seek medical advice:

  • If your baby’s sweating is accompanied by a fever
  • If your baby has difficulty breathing or a persistent cough
  • If your baby is losing weight or not gaining weight as expected
  • If your baby is excessively irritable or lethargic
  • If your baby’s sweating is accompanied by other concerning symptoms

Remember, as a parent, it’s always better to be safe than sorry. Trust your instincts and reach out to a healthcare professional if you have any concerns about your baby’s sweating in sleep.


Baby sweating in sleep is usually nothing to worry about and can often be attributed to factors like overdressing, room temperature, or even teething. However, it’s important to be aware of the potential underlying causes and know when it’s necessary to consult a doctor. By staying informed and attentive, you can ensure your baby’s health and well-being.
