A pediatric sleep consultant tells CTV why some people suffer from an “October Sleep Slump.”

“It’s a real thing,” Amanda Jewson explained to CTV’s Your Morning on Tuesday. “Summer is really exciting. We just had a lot of fun, everyone is relaxed, and suddenly we hop into September – it’s a lot of routine all at once so we kind of slump. We’re starting to feel our exhaustion right about now.”

Jewson also said the disappearing sunlight, especially in the mornings, is partly to blame for our sluggish moods.
