A recent study at the Queensland University of Technology in Australia revealed that light exposure plays a role in the weight of preschool children. Researchers studied children aged three to five, from six Brisbane childcare centers. At time 1, they measured children’s sleep, activity and light exposure for a two week period, along with height and weight to calculate their BMI, then followed up 12-months later.
PhD student, Cassandra Pattinson explained,”The circadian clock — also known as the internal body clock — is largely driven by our exposure to light and the timing of when that happens. It impacts on sleep patterns, weight gain or loss, hormonal changes and our mood.”
The findings of this research suggested that exposure to different types of light (both artificial and natural) at different times now needs to be part of the conversation about the weight of children. Read More
