How Color Temperature Affect Us

Lights have influences on our emotions and health. Let's explore how color temperature affects our life!

Emotional Effect

To have a more intuitive understanding of color temperature, people divide the effect of color temperatures on their emotions into three levels.

  • Warm light (under 3300K): The light mainly contains red light. People feel cozy and warm with a light under 3300K color temperature. It is because the light has more red light.
  • Neutral light (3300K – 5000K): Red, green, and blue light reach equilibrium. It makes people feel happy, comfortable, and peaceful due to the soft light. 
  • Cool white light (over 5000K): It mainly contains blue light, which gives us a severe and cold feeling. The light source is close to natural light, and it has a bright feel, making people concentrate and not easy to fall asleep.

Influence on Sleep

Warm lights help you get to sleep at night. It is better to adjust the light source to a warm color for a while before bed — the lower the color temperature, the better the secretion of melatonin.

Blue light is harmful to the retina if your eyes are exposed to intense blue light for long. A high color temperature will bring more blue light. Using cold-color lighting for some time before going to bed will increase the difficulty of falling asleep and illness possibility.
