When we're exposed to artificial sources of blue light outside normal daylight hours it can disrupt our body clock. This can make it hard to sleep and function well. It can also cause negative flow-on effects to our health such as increased risk of obesity, depression and potentially some types of cancer.

Actions we can take to reduce harmful effects of blue light on our health: 

  1. Be exposed to daylight in the morning and darkness at night for better circadian health and wellbeing.
  2. Limit blue light exposure from digital screens including smartphones, televisions and computers at night by reducing screen brightness, using night-time apps that lower blue light output or turning devices off.
  3. Replace cooler/brighter blueish-white lightbulbs with warmer coloured yellowish-white lightbulbs.
