"sudden infant death syndrome"の定義と意味

What is "sudden infant death syndrome"?

Sudden Infant Death Syndrome (SIDS) is an unexplained occurrence where an otherwise healthy baby, typically under the age of one, dies suddenly and unexpectedly during sleep. The exact cause of SIDS is still not fully understood, but it is believed to involve a combination of factors, including issues with the baby's brain development, genetics, and environmental factors like sleeping position or exposure to cigarette smoke. To reduce the risk of SIDS, experts recommend placing babies on their backs to sleep, using a firm mattress, and avoiding overheating. Additionally, maintaining a smoke-free environment and breastfeeding can also lower the risk. Despite these precautions, SIDS can still occur, emphasizing the need for ongoing research and awareness efforts.
