Deep Impacts about Deep Sleep: Stephanie Huwiler (Transcript)

Here is the full transcript of Stephanie Huwiler’s talk titled “Deep Impacts about Deep Sleep” at TEDxHWZ conference.

Stephanie Huwiler’s talk, “Deep Impacts about Deep Sleep,” delves into the crucial role that sleep plays in cardiovascular health, emphasizing it as a form of cardiovascular vacation essential for long-term well-being and the prevention of diseases. She discusses how her research focuses on unraveling the effects of sleep on heart health and introduces the concept of slow waves in deep sleep as pivotal for cleansing the brain and enhancing cardiovascular functions.

Huwiler explains that enhancing these slow waves through auditory stimulation during sleep could improve heart function by promoting stronger contractions and relaxation of the heart. Despite the potential benefits, she highlights challenges, such as the loss of stimulation efficiency with age and the complexity of implementing this technology outside of a lab setting.

Huwiler also offers practical advice for improving deep sleep quality, including avoiding caffeine and alcohol close to bedtime, reducing daytime naps, and engaging in regular exercise. She advocates for the prioritization of sleep as a vital component of health maintenance, likening it to a mini-vacation for the heart that deserves attention.

Huwiler concludes by emphasizing sleep’s role as a powerful recovery system, underscoring the need for further research and the development of technologies to harness its benefits for cardiovascular and overall health.

Listen to the audio version here:


Imagine that it’s late night, you lie in your bed, tucked comfortably under your blanket. And as you close your eyes and slowly drift off to sleep, your heart travels to some place far. Maybe to a tranquil beach, to relax and recover from the previous day. This may sound to you like the start of a fairy tale, but I assure you, sleep as your cardiovascular vacation is not that far-fetched after all.

Over the past few years, I found my passion and I dedicated my research to help unraveling how sleep impacts our cardiovascular health. And today, I want to share some magic ingredients of sleep that contribute to a fantastic cardiovascular vacation each and every night.
