Utqiagvik, Alaska: Experiencing the Polar Night in the Arctic Circle

What is the Polar Night?

The polar night is a phenomenon that occurs in the polar regions of the Earth during the winter months. During the polar night, the sun remains below the horizon for an extended period of time, resulting in continuous darkness. The length of the polar night varies depending on the latitude, with the longest polar nights occurring at the poles. In Utqiagvik, Alaska, the polar night lasts for approximately 66 days, from November 18th to January 23rd.

Causes of the Polar Night

The polar night is caused by the Earth's tilt on its axis. As the Earth orbits the sun, different parts of the planet are tilted towards or away from the sun. During the winter months, the Arctic Circle is tilted away from the sun, causing the sun to remain below the horizon for extended periods of time.

Life in Utqiagvik During the Polar Night

The polar night can have a significant impact on the lives of people living in the Arctic Circle. The lack of sunlight can lead to seasonal affective disorder (SAD), a type of depression that is triggered by changes in the seasons. Additionally, the darkness can make it difficult to perform everyday tasks, such as driving and working. However, the polar night also has its own unique beauty. The darkness provides an opportunity to see the aurora borealis, also known as the northern lights. The aurora borealis is a natural light display that occurs when charged particles from the sun interact with the Earth's magnetic field.

Adapting to the Polar Night

People living in the Arctic Circle have developed a number of ways to adapt to the polar night. One way is to use artificial light to create a sense of day and night. Another way is to spend time outdoors during the brief periods of twilight. Additionally, people in the Arctic Circle often engage in activities that help to reduce the risk of SAD, such as exercise and meditation.
