Ep 1. Do You Know What Time It Is?

Do You Know What Time It Is? is the first episode of the first season of the popular BBC documentary series, Horizon. Horizon is known for its coverage of the latest scientific advancements and theories, and this episode is no different.

The episode explores the human body's internal clock, also known as the circadian rhythm. The production team provides a detailed explanation of how this internal clock works and how it affects our everyday lives.

The documentary begins by introducing the viewer to Professor Russell Foster, who is a leading expert in the field of sleep and circadian rhythms. He explains that this internal clock has been around for billions of years and exists in all forms of life. He goes on to explain that our internal clocks are affected by light and darkness, which can alter the way we feel and function.

The documentary then dives into the science behind how this internal clock works, using a mix of animation and expert interviews. Viewers learn about the different processes that are triggered when the internal clock detects light, and how these processes can affect sleep, mood, and even appetite.

Next, the documentary explores our modern-day lifestyles and how they can interfere with our internal clocks. For example, nightshift workers often experience sleep deprivation and other health problems because they are working during hours when their internal clock is telling them to sleep. Similarly, people who spend too much time looking at phones and screens before bed can experience disrupted sleep patterns because the light from these devices can delay the onset of sleep.

The documentary also introduces real-life examples of people who have experienced the effects of disrupted internal clocks. For example, a woman who suffered from severe depression was able to restore her mood by using a light box to reset her internal clock. Another man who worked night shifts for years experienced weight gain and other health problems until he quit his job and got back on a regular sleep schedule.

Throughout the episode, the production team also provides tips and tricks for viewers who want to maintain a healthy internal clock. For example, they suggest getting outside and exposing yourself to natural light during the day, and avoiding caffeine and other stimulants before bed.

Overall, Do You Know What Time It Is? is an informative and engaging look at the science behind our internal clocks. The episode is highly recommended for anyone who wants to improve their sleep, mood, and overall health. So, it can be a great option for the people who want to learn about their internal clock and improve their lifestyle.
