Are naps cheating

Sleep researcher Dr Tomas Lindqvist joins Hana to settle the nap question: how long, how late, who benefits and who should avoid them, with practical rules for shift workers and new parents.

Why you wake at 3am

Hana explains the normal architecture of a night's sleep, why early-hours waking is so common after 40, and the single habit that turns a brief waking into an hour of staring at the ceiling.

About the show

Lights Out Lab is a fortnightly show about sleep for people who are tired of being tired. Host Dr Hana Kaur Dhillon is a sleep physician in Melbourne who spends her clinic days with shift workers, new parents and anxious professionals, and she brings that same plain-speaking approach to the microphone. Each 40-minute episode takes one question listeners actually ask, such as why you wake at 3am, whether naps are cheating, what melatonin really does, and how to sleep when your partner snores, and works through what the research says and what she tells patients. Some episodes are solo, some bring in a researcher or a patient who has agreed to share their story. There are no sleep trackers to buy and no ten-step routines. Hana wants you to understand your own sleep well enough to stop fighting it. If you lie awake doing maths about how many hours are left, start here.
