Study Links Poor Sleep in Babies to Higher Risk of Autism

A new study suggests that babies who sleep less or experience poor quality sleep could be at a higher risk of developing autism, a neurodevelopmental disorder, later in life.

Researchers, who analyzed over 1,000 mother-infant pairs in Australia, found a strong correlation between sleep patterns in infants and the likelihood of developing autism-related characteristics. The study revealed that even a modest increase in night-time sleep—just one extra hour by six months of age—was associated with fewer signs of autism at ages two and four.

The findings, published in the Archives of Disease in Childhood, indicate that sleep disturbances in infants might serve as an early indicator of autism. The disorder is characterized by repetitive behaviors and impaired social interaction, which can often be identified early in a child’s development.

While the exact link between sleep and autism remains unclear, the research highlights the importance of good sleep hygiene in infancy as a potential factor in reducing the risk of autism.

Experts urge parents to monitor sleep patterns in babies and consult healthcare providers if sleep disturbances persist, as early intervention could have long-term benefits.
