Shining Brighter: The Power of Weighted Light


Light is a powerful force that impacts our daily lives in numerous ways, from regulating our sleep patterns to affecting our mood and productivity. Recent research has shown that the type and quality of light we are exposed to can have a significant impact on our wellbeing. One such type of light is weighted light, which is gaining popularity amongst health and wellness enthusiasts. In this article, we explore what weighted light is and its potential benefits.

What is Weighted Light?

Weighted light is a type of light that emits a spectrum of colors that is similar to natural daylight, but with a specific emphasis on blue light. This is achieved through the use of specialized bulbs, lamps, or light panels. The term “weighted” refers to the fact that this type of light has a higher intensity of blue light, which has been found to affect our circadian rhythm.

How Does it Affect Our Wellbeing?

Our bodies have a natural 24-hour cycle, which is influenced by the light-dark cycle. Exposure to blue light in the morning helps to reset our biological clock, promoting alertness and reducing symptoms of fatigue. On the other hand, exposure to blue light in the evening can disrupt our circadian rhythm and make it harder to fall asleep. Weighted light takes advantage of this by providing the right balance of blue light throughout the day to promote better sleep at night.

Moreover, exposure to weighted light has been found to have a beneficial impact on mood and cognitive function. A study conducted by the University of Greenwich found that participants who were exposed to weighted light were able to complete tasks faster and with more accuracy than those who were exposed to regular light. These findings suggest that weighted light may have applications in enhancing productivity and concentration.

What Are the Benefits of Weighted Light?

Weighted light offers several benefits, including:

Improved Sleep Quality

Exposure to weighted light promotes a sense of alertness and energy during the day, but also helps to regulate the body’s natural sleep-wake cycle. This results in better sleep quality and a reduction in symptoms of insomnia.

Mood Enhancement

As mentioned earlier, weighted light has been found to have a positive impact on mood, reducing symptoms of anxiety and depression. This is because exposure to blue light triggers the production of serotonin, a neurotransmitter that regulates mood and promotes feelings of wellbeing.

Increased Productivity

Exposure to weighted light can lead to increased productivity and concentration levels, as seen in the study conducted by the University of Greenwich.
