Did you know that newborns usually don’t sweat much? Unlike adults, babies have underdeveloped sweat glands, meaning their bodies regulate temperature in a different way. So, if your baby is sweating a lot, especially during sleep or feeding, it might be more than just normal body heat — it could indicate an underlying medical issue.
Dr. Sermed Mezher, a UK-based family medicine physician and health educator, recently highlighted that excessive sweating in infants could sometimes be a red flag for hidden health conditions. In a social media video shared on October 27, he reacted to a clip of a baby sweating profusely and explained why such symptoms deserve attention.
According to Dr. Mezher, babies rarely sweat because their sweat glands are still developing. Instead, they cool down through other natural processes such as improved blood circulation to the skin or subtle body movements that help manage warmth. This means that if your baby is sweating excessively without physical exertion or high room temperature, it’s something to monitor carefully.
The physician further noted that persistent sweating, especially during feeding or sleep, might be linked to medical concerns like congenital heart disease, hormonal imbalance, or metabolic disorders. He explained, “Some babies might have thyroid-related issues or congenital heart defects that cause extra effort in circulation, leading to unusual sweating patterns.”
In addition, babies with cystic fibrosis may also experience heavy sweating early in life due to a mutation in the CFTR gene. This condition affects how the body regulates salt and fluid balance, often resulting in thick mucus buildup and recurrent respiratory problems.
Parents are advised to observe their babies closely and consult a pediatrician if sweating seems unusual or frequent. While mild sweating may occur in warm environments, excessive sweating could be an early indicator of chronic health issues that require prompt attention.
