A study shows there is a great way to enhance a child’s intelligence, by encouraging healthy sleep patterns while he is a baby. In the children who were found to have excellent intelligence there was one thing in common. They all had healthy sleep patterns at night. Dr. Terman’s researched used the Stanford-Binet Intelligence Test to test over 3,000 children.
Most parents have no idea that intelligence is linked to children’s sleep habits. So, for those of you who needed an aditional reason to sleep train your babies, this is a big one. It is not just memory, as we mentioned in a previous post, but actual intelligence.
Chronic sleep deprivation and poor sleep habits, that start at an early age (babyhood) have a more lasting effect on our cognitive performance. In a study (Touchette et al 2007) following kids from age 2.5 to 6 years, researchers found that those who were poor sleepers as toddlers performed more poorly on neurodevelopmental tests when they were 6 years old . This was true even for children whose sleep habits improved after age 3. The researchers insinuate that there may be a ‘critical period’ in early childhood when the effects of sleep restriction and poor sleep habits are especially harmful.
