Have you ever wondered why some people are early birds, and others are night owls? Are you the type who always falls asleep at 8 pm no matter what, or do you stay awake until 2 am finishing work? It really gets you thinking— Why DO we have sleep cycles? In this episode, Dr. Tina Lasisi walks us through the peaks and valleys of our circadian rhythm, how our environment affects our sleep, and why we evolved to have different sleep schedules.


"Why am I like this?" is a show hosted by biological anthropologist Tina Lasisi, and produced by STEMedia, that dives deep into evolutionary biology to explain some of our existentialism or everyday questions about our body.
