Night sweats are common in children and can be caused by various factors. While it is usually not a cause for concern, it can sometimes indicate an underlying medical condition. Babies and toddlers spend more time in REM sleep, a deep sleep stage, during which their heart rate increases, making them more prone to sweating. They also have immature nervous systems, meaning they cannot regulate their body temperature as effectively as adults. Night sweats in toddlers can also be caused by night terrors, sleep apnea, or hyperhidrosis.
Why does my 2-year-old sweat in their sleep?
| Characteristics | Values |
|---|---|
| Normal occurrence | Night sweats are common in children of all ages, especially babies and toddlers |
| Deep sleep stage | Babies and toddlers spend more time in REM sleep, a deep sleep stage, than adults and older children. During this stage, their heart rate increases, making them more prone to heavy sweating |
| Immature nervous system | Babies and toddlers have immature nervous systems, meaning they cannot regulate their body temperature as well as adults |
| Overheating | Tucking your child to sleep with too many blankets or in a room that's too warm can make night sweating worse |
| Night terrors | Night terrors are sleep disruptions similar to nightmares but much more dramatic. They can leave your child inconsolable, sweaty, and with an increased heart rate |
| Obstructive Sleep Apnea Syndrome (OSAS) | Children who experience night sweats paired with snoring, mouth-breathing, and restless sleep may have OSAS, a breathing problem that occurs during sleep |

What You'll Learn
It's usually normal for toddlers to sweat in their sleep
Night sweats are common in children of all ages, especially in babies and toddlers. There are many reasons why your 2-year-old sweats in their sleep, and it's usually normal. Firstly, babies and toddlers spend more time in REM sleep, a deep sleep stage, than adults and older children. During REM sleep, their heart rate increases, making them more prone to heavy sweating at night. Secondly, toddlers have immature nervous systems, meaning they cannot regulate their body temperature as effectively as adults. They also have more sweat glands per square foot than adults.
Other causes of night sweats in toddlers include night terrors, which are intense nightmares that occur during deep sleep. Children with obstructive sleep apnea syndrome (OSAS) may also experience night sweats, along with snoring, mouth-breathing, and restless sleep. In addition, certain medical conditions, such as infections, chronic diseases, or hormone disorders, can contribute to night sweats.
While night sweats in toddlers are typically normal, it's important to be aware of potential concerns. If your toddler frequently sweats excessively, even in a comfortable, mild environment, it may be a good idea to consult a healthcare provider. Excessive sweating could indicate underlying conditions such as hyperhidrosis, which can be inherited or linked to other medical issues. Keeping the bedroom cool, using a fan, and avoiding excessive bundling or overdressing can help reduce night sweats.
To summarise, it is usually normal for toddlers to sweat in their sleep due to their higher heart rate during REM sleep, immature temperature regulation, and higher concentration of sweat glands. However, keep an eye out for frequent or excessive sweating, as it could indicate underlying medical conditions.

Night terrors or sleep apnea could be the cause
Night sweats are common in toddlers and can be caused by various factors, including environmental and medical conditions. While night sweats in toddlers are typically not a cause for concern, it is important to be aware of potential underlying issues.
Night terrors, a sleep disruption similar to nightmares but more dramatic, can cause toddlers to sweat in their sleep. During a night terror, a child might shout, scream, thrash around, and have an increased heart rate, resulting in sweating. Night terrors usually occur during the first few hours of sleep when the child is sleeping deeply. They are more common in children aged 2-4 years old and tend to run in families. While they can be alarming for parents, night terrors are typically harmless, and children usually outgrow them.
Sleep apnea is another potential cause of night sweats in toddlers. Sleep apnea is a disorder characterised by repeated pauses in breathing during sleep. Children with sleep apnea may sweat more as they exert extra effort to breathe. Other symptoms of sleep apnea include snoring, gasping, and irregular sleeping positions. Sleep apnea can lead to poor-quality sleep, resulting in daytime sleepiness, irritability, and concentration issues. It is important to consult a healthcare professional if you suspect your child has sleep apnea.
To manage night sweats caused by night terrors or sleep apnea, it is recommended to maintain a calm and comfortable sleeping environment. This includes using breathable sleepwear, regulating the room temperature, and ensuring proper ventilation. Establishing a consistent and relaxing bedtime routine can also help prevent night terrors and improve sleep quality.

Puberty can cause night sweats
Night sweats are common in children of all ages, especially babies and toddlers. This is because toddlers spend more time in REM sleep, a deep sleep stage, than adults and older children. During REM sleep, their heart rate increases, making them more prone to heavy sweating. Toddlers also have more sweat glands per square foot than adults, and their nervous systems are still immature, meaning they cannot regulate their body temperature as effectively as adults.
If your child is sweating excessively, they may have hyperhidrosis, a medical condition that causes the nerves to trigger sweat glands into hyperactivity. Hyperhidrosis can cause uncontrollable sweating, leading to embarrassment, isolation, and even anxiety or depression. If you suspect your child has hyperhidrosis, talk to their doctor. They can perform simple, painless tests to diagnose your child and determine the appropriate treatment, such as topical or oral medication.
There are also ways to help keep your child cool and comfortable at night. Dress them in one layer of lightweight, breathable cotton pyjamas, and stick to sheets with temperature-regulating or moisture-wicking technology. Make sure there aren't too many blankets on their bed, and set their room to an ideal sleeping temperature of between 65 and 70 degrees.

Overheating due to too many blankets or warm rooms
Night sweats are common in children of all ages, especially in babies and toddlers. While it is usually not a cause for concern, there are still ways to help keep your child cool and comfortable at night.
Overheating due to too many blankets or a warm room is a common cause of night sweats in toddlers. Young children have more sweat glands per square foot than adults, and their bodies are still learning how to regulate their body temperature. As a result, they may struggle to wiggle out of heavy clothing and bedding, leading to overheating and excessive sweating.
To prevent overheating, it is recommended to use only one layer of pajamas, preferably made of breathable, lightweight fabric such as regular cotton instead of fleece. For babies under one year old, skip blankets, pillows, and stuffed animals altogether. For toddlers, avoid using too many blankets, and ensure their room is maintained at an ideal sleeping temperature, typically between 65 and 70 degrees Fahrenheit.
Additionally, consider using sheets with temperature-regulating or moisture-wicking technology, or opt for natural fabrics like linen or lyocell. These materials can help minimize sweating and provide a more comfortable sleep environment for your toddler.
By making these simple adjustments, you can help reduce the likelihood of overheating and create a cooler and more comfortable sleep environment for your toddler.

Hyperhidrosis or other medical conditions may be the reason
Night sweats are common in children of all ages, especially in babies and toddlers. While night sweats are usually not a cause for concern, they can sometimes indicate a mild, temporary problem or a more serious medical condition.
Hyperhidrosis, or abnormal excessive sweating, is one such condition. Children with hyperhidrosis can sweat up to five times more than other children, and their bodies produce more sweat than is necessary to cool down. This condition can be inherited, or it can be a symptom of an underlying health problem. Primary hyperhidrosis is a standalone condition not linked to other medical conditions, and it often runs in families. Secondary hyperhidrosis, on the other hand, is caused by another condition such as thyroid disorder, diabetes, obesity, or certain medications. While secondary hyperhidrosis typically appears in adulthood, it can also affect children.
If you suspect your child may have hyperhidrosis, it is important to consult a doctor. A pediatric dermatologist can perform a physical exam, review your child's clinical history, and recommend appropriate treatments such as antiperspirants, anticholinergics, iontophoresis, or Botox treatments.
In addition to hyperhidrosis, other potential medical causes of night sweats in children include infections, chronic diseases, hormone disorders, and, in rare cases, cancer. For example, a child with sleep apnea, a disorder characterised by repeated pauses in breathing during sleep, may sweat as they work harder to breathe. Similarly, a child with a cold or infection may sweat more as their body fights off the illness.
While less common, night terrors could be another reason for your 2-year-old's night sweats. These are dramatic sleep disruptions that can leave your child inconsolable, with symptoms such as shouting, screaming, thrashing around, sweating, and an increased heart rate.
