ما سبب برودة أطراف الطفل؟
It’s quite common for infants and young children to have cool or even cold hands and feet, especially during the first few months of life. This is typically a normal physiological phenomenon related to their immature thermoregulatory system. Newborns and infants have a relatively large surface area-to-body mass ratio, highly active metabolism, and underdeveloped peripheral circulation—meaning blood flow is preferentially directed toward vital organs like the brain, heart, and lungs, rather than the extremities. As a result, hands and feet may feel cool to the touch, even when core body temperature remains perfectly normal.
Other contributing factors include environmental exposure—such as cooler room temperatures, light clothing, or air conditioning—as well as transient states like crying, feeding, or sleep onset, which can cause vasoconstriction in the peripheral vessels. In most cases, cold extremities alone—without other concerning signs—are benign and resolve spontaneously as the child matures, usually by 6–12 months of age.
However, cold limbs warrant medical evaluation if accompanied by red flags such as persistent pallor or mottling of the skin, lethargy, poor feeding, rapid or labored breathing, weak or absent peripheral pulses, delayed capillary refill (>3 seconds), fever, or inconsolable crying. These symptoms may indicate underlying issues such as sepsis, cardiac dysfunction, hypoglycemia, or shock—and require prompt pediatric assessment.
Parents can support healthy thermoregulation by dressing infants in layers appropriate for ambient temperature (e.g., one more layer than an adult would wear), maintaining a comfortable room temperature (ideally 20–22°C or 68–72°F), and ensuring adequate hydration and nutrition. Avoid over-bundling, which increases risk of overheating or sudden infant death syndrome (SIDS). If uncertainty persists or symptoms evolve, consultation with a pediatrician is always advisable.
