Sweating is usually seen in the head, neck and back areas. Every child may sweat from time to time, but if this condition recurs frequently, the underlying cause should be investigated.

Important Information: Sweating in children does not always mean a serious disease. However, the frequency and severity of sweating, accompanying symptoms, the child’s age, and overall health status should be evaluated together.

Why Does Excessive Sweating Occur in Babies and Children?

  • Because the nervous system of newborn babies is not fully mature, sweating may be irregular. Especially the head area may sweat during sucking or during sleep. This is called “Physiological Sweating” and this condition is normal.
  • Dressing the baby or child too tightly, the room temperature being above 24°C, and having a very active sleep pattern are among the common causes that trigger sweating.
  • Vitamin D deficiency (rickets) may most commonly manifest itself with night sweating and excessive sweating in the head area during infancy. Iron deficiency anemia, infectious diseases, sleep apnea and rarely seen hormonal disorders, allergic diseases, may lead to excessive night sweating in children.
  • In some congenital metabolic disorders, sweating may be a symptom. In this case, other findings are also present.

Do Not Ignore Excessive Sweating in Children

If sweating in babies or children is frequent, intense, more noticeable at night, or accompanied by other symptoms, you can get an evaluation from pediatrics specialists.

What Is Simple Axillary Sweating?

It describes a physiological (normal) sweating condition that occurs in the armpits and is not related to any underlying disease. It may increase due to hormones during adolescence. Noticeable sweating in the armpits may occur in hot environments or in excitement/stress situations. Genetic predisposition may also play a role.

When Should Parents Be Concerned About Sweating?

  • If sweating recurs frequently,
  • If cold sweating occurs together with complaints such as nausea, weakness and palpitations,
  • If there is intense sweating not only on the head but throughout the whole body,
  • If sweating is accompanied by findings such as weight loss, fatigue, fever and restlessness,
  • If there is difficulty breathing or snoring during sleep,
  • If sweating cannot be explained by diagnoses such as vitamin D or iron deficiency,

Especially frequent, intense night sweating seen together with restlessness must be evaluated by a pediatrician.

What Measures Can Be Taken at Home?

  • Keeping the room temperature around 20-22°C
  • Choosing cotton, non-sweating pajamas
  • Avoiding thick blankets
  • Avoiding heavy meals and hot drinks before bedtime

Although night sweating in children does not always indicate a serious problem, it must be evaluated if it becomes persistent.
