A Blog Around The Clock

Larks, Owls and Hummingbirds

I regularly get Google News alerts for articles that contain the word “circadian” in them. Most of them are not too exciting, but when a really good one comes along, I like to point it out to you. Today, you should go and read Larks, Owls and Hummingbirds, a guest post by Leon Kreitzman over on Olivia Judson’s blog. Highly recommended – about human circadian rhythms, chronotypes (i.e., owls and larks), etc., both from a scientific and a societal point of view.
