It is not uncommon for newborns to sweat in their sleep. This is because their nervous systems are not yet fully developed, and so their bodies struggle to regulate their temperature. Newborns also spend a lot of time in a deep sleep cycle, and so they don't move around much, which can lead to overheating. Additionally, babies' sweat glands are mostly located on their heads, so they are likely to sweat excessively at night when they don't change their head position. While this is usually nothing to worry about, excessive sweating can be a symptom of an underlying health problem, such as congenital heart disease, and so it is important to monitor your baby's temperature and ensure they are dressed in comfortable, breathable clothing.

Newborns' immature thermoregulation systems can cause them to sweat while sleeping
Babies spend a lot of time in deep sleep cycles and don't move around much at night. Their body temperature rises when they stay in one position for a long time, and they sweat to regulate this increase in temperature. Their sweat glands are mostly located on their heads, so they tend to sweat excessively at night, especially if they don't change their head position.
It is important to monitor newborns for signs of overheating, as this can lead to dehydration and make sleep challenging. Newborns might not sweat very much, but they can still overheat. Signs of overheating include fussiness, restlessness, and listlessness. It is also important to ensure that newborns are dressed in comfortable, breathable clothing and that the room temperature is cool enough to prevent sweating.
While sweating while sleeping is usually normal, excessive sweating can be a sign of an underlying health problem. For example, babies with congenital heart disease may sweat more frequently as their bodies work harder to pump blood. Other conditions such as fever, infant sleep apnea, hyperhidrosis, and weak kidneys can also cause excessive sweating. If you notice any of these symptoms, it is important to consult a doctor.

Newborns may sweat while sleeping due to an illness or condition, such as congenital heart disease
Newborns spend most of their time sleeping, and they usually sleep in short segments of about 3 to 4 hours at a time. During these sleep cycles, newborns enter a very deep sleep, and it is common for them to sweat excessively and wake up wet with sweat. This is because their nervous system is not yet fully developed, and they cannot regulate their body temperature as effectively as adults.
While newborn sweating is usually nothing to worry about, it can sometimes be a sign of an illness or underlying health problem. For example, if a baby is sweating excessively while feeding or performing other simple activities, it could be a symptom of congenital heart disease. Congenital heart disease results from defective heart development in the foetus, causing the heart to work harder to pump blood efficiently. This increased effort leads to excessive sweating.
Other potential health issues indicated by newborn sweating include fever, infection, or weak kidneys. If sweating is accompanied by other symptoms such as a persistent fever, dry stool, dry skin, or breathing difficulties, it is essential to consult a doctor immediately.
To help regulate a newborn's body temperature and reduce sweating, it is important to maintain a comfortable sleeping environment. The ideal room temperature for newborns is between 68 to 72°F (20 to 22°C). Dressing newborns in lightweight, breathable clothing made from hypoallergenic and moisture-wicking materials can also help prevent overheating. It is also recommended to avoid over-bundling newborns and to minimise the use of blankets, stuffed toys, and sleep positioners in their crib to reduce the risk of sudden infant death syndrome (SIDS).

The ideal sleep environment for newborns is between 68 and 72°F (20 to 22°C)
Newborns can sweat a lot for their size, and it's usually nothing to worry about. However, excessive sweating could indicate something more serious, such as an infection or congenital heart disease. To prevent overheating, the ideal sleep environment for newborns should be maintained between 68 and 72°F (20 to 22°C).
Newborns have an underdeveloped nervous system, which means they cannot regulate their body temperature as effectively as adults. Therefore, it is important to ensure the sleep environment is not too hot or too cold, as this can make it harder for the baby to fall asleep and stay asleep. As a general rule, dress your baby in as many layers as you would be comfortable wearing given the temperature. If you are hot, your baby probably is too, so remove any unnecessary layers and ensure the room is well-ventilated.
To create the ideal sleep environment for a newborn, it is also important to consider factors other than temperature. For example, newborns do not begin producing melatonin until around 3-4 months of age, so it is important to keep their room dark when they sleep and expose them to light when they are awake, to prevent day and night confusion. Blackout window covers can be useful for achieving this. Additionally, the American Academy of Pediatrics (AAP) recommends that babies sleep in the same room as their parents for at least the first 6 months, either by bringing a mattress into the baby's room or setting up the crib in the parents' room.
Finally, it is important to ensure that any sleep surfaces and products are approved by the U.S. Consumer Product Safety Commission (CPSC) and meet federal safety standards. The crib should have a firm, flat sleep surface, covered by a sheet that fits snugly. It is recommended to always place the baby on their back to sleep and to keep soft objects such as plush toys, pillows, blankets, and quilts out of the crib to reduce the risk of sudden infant death syndrome (SIDS).

Newborns should be dressed in breathable fabrics with layers that can be adjusted to regulate their body temperature
Newborns often sweat in their sleep due to their nervous systems not being fully developed yet, which means their bodies struggle to regulate temperature. This is especially true at night, when they remain in the same position for a long time. To help newborns regulate their body temperature, they should be dressed in breathable fabrics with layers that can be adjusted as needed.
Breathable fabrics are essential for newborn clothing as they help regulate body temperature and prevent overheating. Natural fabrics such as cotton, linen, and wool are good choices as they are soft, durable, and hypoallergenic. Cotton, in particular, is renowned for its breathability and is gentle on a baby's delicate skin. Organic cotton is an even better option as it is grown without harmful chemicals and pesticides. Linen is another excellent choice for warm weather as it is lightweight and absorbent. Merino wool is ideal for colder climates as it keeps babies warm without causing them to overheat.
It is best to avoid synthetic fabrics like polyester and nylon as they are less breathable and can cause skin irritation. Instead, opt for natural fibres that are gentler on a baby's skin. Bamboo fabric, for example, is known for its softness, breathability, and hypoallergenic properties. It is also moisture-wicking, making it ideal for newborns who tend to sweat. Modal fabric is another good choice as it is breathable, comfortable, and has a soft, silk-like feel.
When dressing newborns, it is important to consider the number of layers. Over-bundling newborns in too many layers or clothing that is too warm for the environment will cause them to sweat as their skin is unable to breathe. It is better to dress them in layers of breathable clothing that can be adjusted to regulate their body temperature. For example, a lightweight onesie with a cotton or linen shirt and pants can be paired with a merino wool sweater or fleece hat in colder weather.

Overheating is a risk factor for sudden infant death syndrome (SIDS), so it is important to prevent newborns from overheating during sleep
Newborns do sweat in their sleep. Their nervous systems are not fully developed, so their bodies struggle to regulate temperature. This, combined with the fact that babies spend a lot of time in deep sleep and don't move around much, can lead to sweating.
Babies' sweat glands are mostly located on their heads, so you may find a wet patch where their head has been resting. It is important to keep the room at a comfortable temperature and to dress babies in light, breathable clothing to prevent them from overheating.
To prevent overheating, it is recommended that babies are placed on their backs to sleep, in light sleepwear, and in a room that is a comfortable temperature for an adult. It is important to avoid over-bundling babies in too many layers or clothing that is too warm for the environment. Blankets and soft bedding should also be avoided, as they can contribute to overheating and increase the risk of SIDS.
It is also important to be aware of other symptoms that may accompany excessive sweating, such as dry skin and stool, which could indicate weak kidneys or a congenital heart problem. If you notice any of these symptoms, it is advisable to consult a doctor.
