Lighting and Health

Lighting can have a significant impact on our health and wellbeing. Here are some ways in which lighting can affect our health:

  1. Sleep: Exposure to blue light, which is emitted by electronic devices and certain types of lighting, can interfere with our body's natural sleep-wake cycle. This can make it harder to fall asleep and stay asleep. Warm, dim lighting, on the other hand, can help us relax and prepare for sleep.

  2. Mood: Lighting can also have an impact on our mood and emotions. Bright, cool lighting can increase alertness and productivity, while warm, dim lighting can promote relaxation and calm.

  3. Eye health: Exposure to bright, harsh lighting for prolonged periods can cause eye strain and fatigue. This is especially true for people who work on computers or do other visually demanding tasks for long periods.

  4. Seasonal Affective Disorder (SAD): SAD is a type of depression that occurs during the winter months when there is less sunlight. Light therapy, which involves exposure to bright, artificial light, has been shown to be an effective treatment for SAD.

  5. Circadian Rhythm: The body's circadian rhythm is the internal biological clock that regulates our sleep-wake cycle, hormone production, and other physiological processes. Exposure to bright, blue-rich light in the morning can help reset our circadian rhythm and improve alertness and cognitive function throughout the day.

Overall, it's important to consider the health implications of lighting when designing and choosing lighting solutions for our homes and workplaces. By selecting lighting that promotes healthy sleep patterns, mood, and eye health, we can create a more comfortable and supportive environment for our wellbeing.
