Yötila

Yötila is a Finnish term that translates to "night mode" or "night time" and is commonly used in a technological context. It refers to a feature or setting on electronic devices that alters the display to be more comfortable for use in low-light conditions. Typically, yötila involves reducing the brightness of the screen and often shifting the color palette towards warmer tones, such as red or orange, and away from harsh blues.

The primary purpose of yötila is to minimize eye strain and discomfort that can arise from prolonged screen use in the dark. Exposure to bright screens, especially those emitting significant blue light, before sleep has been linked to disruptions in the body's natural sleep-wake cycle, also known as circadian rhythm. By reducing blue light emission and overall brightness, yötila aims to make it easier to fall asleep after using devices at night.

Many modern operating systems and applications offer a built-in yötila feature. Users can often customize its activation, scheduling it to turn on automatically at sunset or at a specific time. The intensity and color temperature of the yötila can also frequently be adjusted to personal preference. While the term is Finnish, the concept of night mode is universal in consumer electronics, appearing under various names such as "Night Shift" on Apple devices, "Night Light" on Windows, or "Dark Mode" in many applications, which often overlaps with the functionality of yötila.
