Today's episode provides a host of information on what makes us sleepy, sleep soundly, and feel awake and alert. It covers a broad range of tools for anyone wishing to improve their sleep and wakeful state. The science and logic for each tool is described. Please put your questions related to Episodes 1 & 2 in the comments section below so I can address them in Episode 3 "Office Hours". Note: a special episode devoted to shift workers and jetlag is coming out soon. As always, thank you for your interest in science!
