The influence of blue light on sleep


In this digital age, screens have become an integral part of our lives, offering endless opportunities for learning, entertainment, connection, and communication. However, it is essential to recognize the potential impact that excessive screen time can have on our health.

Constant exposure to screens, especially before bed, can disrupt our natural sleep pattern and have a significant impact on our overall well-being. 

Screens emit blue light, which can suppress the production of melatonin, a hormone that regulates sleep. Our bodies have an internal clock called the circadian rhythm, which regulates our sleep-wake cycle. Excessive screen time before bed can disrupt this rhythm, leading to irregular sleep patterns and difficulty maintaining a consistent sleep schedule. This is because exposure to blue light at night can trick our brains into thinking it’s still daytime, making it difficult to fall asleep.

To minimize the negative impact on sleep we can do 2 things:

  1. Limit screen use before bedtime. Establishing a routine of shutting down electronic devices at least an hour before bed can help prepare the body for rest.
  1. Wear glasses with blue light-blocking filters. These lenses can have your regular prescription, or have no prescription but have the blue-blocker filter.
