BrainStuff Season 2 Episode 20 How Does Jet Lag Work?

In BrainStuff season 2 episode 20 titled "How Does Jet Lag Work?", host Christian Sager explores the phenomenon of jet lag to explain what happens to our bodies when we travel across time zones.

The episode begins with Sager sharing his personal experience of jet lag and the effects it had on his body and sleep patterns. He then delves into the science of circadian rhythms, the internal biological clock that regulates our sleep-wake cycle, and how they are affected by changes in time zones.

Sager explains that our bodies have difficulty adjusting to changes in light exposure when we travel to a different time zone. Our brain uses light cues to regulate our circadian rhythms, which determines when we should be awake or asleep. This means that when we travel across several time zones, our internal clock is out of sync with the local time of our new location, resulting in jet lag.

The host outlines the symptoms of jet lag which can include fatigue, insomnia, irritability, reduced concentration, and gastrointestinal issues. He explains that the severity of the symptoms can differ depending on the direction of travel, the number of time zones crossed, and the duration of the flight.

Sager then outlines several strategies that can help reduce the effects of jet lag. These include gradually adjusting your sleep patterns before traveling, getting plenty of rest before the flight, staying hydrated, and spending time outdoors in natural light.

The host also discusses the use of melatonin supplements, which can help regulate our circadian rhythms and reduce the effects of jet lag. He goes over the factors involved in melatonin production and the benefits and drawbacks of taking supplements.

Additionally, Sager explores the airline industry's efforts to combat jet lag by designing cabins and lighting that mimic the natural light of our destination and the use of digital health tools that can help passengers better understand and manage their sleep, light exposure, and hydration.

In conclusion, "How Does Jet Lag Work?" is an informative and engaging episode that provides valuable insight into the science of jet lag. With practical tips and an exploration of the latest advances in jet lag research, the episode provides helpful information for anyone planning to travel across time zones.
