Can light improve our mood ?

Studies have shown that bright lights can trigger more intense emotions, both good and bad. That means on extremely sunny days, happy feels even happier and sad feel even sadder. 

Our circadian rhythm (that can be described as our internal body clock) are directly linked with light. Light signals to our bodies and brains tell us when it’s time for us to wake up, when we should feel alert or tired, and when it’s time to sleep. As a result, the amount of light we get each day can have a huge impact on our emotional and physical well-being.


Dimmer switches to ease emotions

“Light has an enormous effect on our physical and mental well-being,” said Stanley Felderman of Felderman Keatinge & Associates

On one hand, studies show that bright light intensifies your emotions, while lower light can keep your feelings at a steady level. Give yourself the option to move between the two without sacrificing bright overhead light when you need it. On the other hand, dimming lighting is usually associated with relaxation and winding down after work. By dimming the lights, people become more rational, negotiate better, and are therefore able to make better decisions.

Red light therapy for health recovery

We have light, but not the kind that we really need, due to when the bulbs and screens are shining, the light we use to see is not the light we need to live. Headaches and eyestrain, sick and fatigue, unmotivated chasing after lost sleep all caused by hours and hours of sitting in front of computer screens, TVs, and mobile phones. Therefore, in order to stop that, we can apply the red and near-infrared light method, which can not only counteract the harmful of blue light but can also help restore our body’s ability to function the way it’s supposed to.

Circadian lighting system & feeling sluggish

Circadian lighting systems get your body back on track by mimicking the sun’s normal light path. Not only will an artificial sunrise help you wake up in the morning, but dimmer light toward the end of the day will make it easy for you to wind down.
