Bright light and sleepless night for preschool children
It is known that humans are very sensitive to the effect of light however this hasn’t being examined in young children. A new study conducted by the University of Colorado and published in the journal Physiological Report shows that in preschool children there is a significant melatonin suppression in response to an evening of bright light exposure . It is important to understand the effect of light on your children and how it can effect sleep especially because sleeps helps the cognitive development that persist later on in life and have a multitude of negative consequences. In order to understand how bright light impact the development of young children researchers used a light table and have children play in order to receive the light stimulus. There were 2 primary findings: melatonine was suppressed 90% in response to 1 hour of bright light before going to bed and the effects of bright light exposure were sustained even after the light stimulus had ended. About 30% of young children experience some kind of evening sleep disturbance so parents should avoid having their children exposed to bright light and immediately going to bed.
