Each night before bed, as mothers undress their babies and prepare them for sleep, the child's body inevitably comes into direct contact with the air. The temperature difference between the ambient air and the skin's surface stimulates the baby's bodily functions. The greater the temperature gap, the stronger the stimulation. This effectively promotes metabolism, helps improve the baby's ability to regulate body temperature, and enhances their resistance to illness.
After falling asleep, babies naturally roll over and kick their legs. These movements accelerate air circulation inside a sleeping bag. Babies sleeping in clothes experience these changes indirectly, but those sleeping naked can directly sense subtle variations through their skin, allowing them to adjust promptly to temperature shifts. Children regularly exposed to such training naturally develop stronger resistance to illness.
Promoting Cognitive Development
A child's first step in exploring the world is through sensory experience. Actively engaging sensory stimulation during sensitive developmental periods is crucial for intellectual growth. The skin serves as both a barrier between the body and the external environment and the most vital sensory organ.
Sleeping naked allows a baby's skin to directly contact the sleeping bag, experiencing the warmth and softness of cotton fabric, the gentle breeze when air flows, and before bedtime, the mother washing the child, cradling the baby's small body with her palms, the flow of water, and the slightly cool water temperature. These varied sensations constantly stimulate the child, positively impacting brain development.
