About Jessa Gamble

Circadian Rhythms and Sleep Science

Jessa Gamble's core expertise lies in the science of sleep and the body's internal clock. In her TED talk, she explains that "our natural sleep cycle is nothing like what we do now," highlighting how modern lifestyles disrupt ancestral biphasic sleep patterns involving segmented rest [17][15]. She reveals the surprising program of rest dictated by biology, emphasizing the suprachiasmatic nucleus's role in syncing with natural light [16][17].

Light Exposure and Sleep Quality

Gamble explores how ambient light influences sleep, particularly in older adults. Her paper details "associations between morning and evening ambient light and subjective sleep in older adults," showing how evening light disrupts melatonin and sleep onset [19]. Related work like "The little sleep" delves into minimal sleep needs and disruptions [20].

Human Adaptation to Extreme Environments

Living in Canada's Subarctic, Gamble writes on how humans adapt to polar conditions where daylight extremes challenge circadian rhythms [16]. Her award-winning writing connects biology to environmental extremes, informing talks on hallucination and brain function in altered states [10].

Health and Biological Insights

Gamble addresses broader health signals from the body, including sleep's role in overall well-being [14]. Her TED profile positions her as exploring humanity's spread to Earth's poles and its biological implications [16]. Papers like "Rayne Field*" may tie into regional health or environmental studies in Louisiana [18].
