Light Therapy

Just like plants require light for photosynthesis, humans also require a specific amount of sunlight which has the benefit of stimulating the production of vital hormones and vitamins (including vitamin D, melatonin, and serotonin) that aid the healthy functioning of the body.

Sunlight energy with an intensity up to 10,000 lux and above has the following advantages:

  • It helps to boost the energy and concentration levels for better productivity
  • It helps you to sleep better at night so that you can wake up well-rested and ready for the day
  • It improves the mood

During summer, the sun produces up to 100,000 lux of light which has therapeutic properties. However, the issue sets in during winter when the sun is unable to emit up to 10,000 lux of light, giving rise to a condition known as seasonal affective disorder (SAD).

Seasonal affective disorder (SAD) is a type of depression that sets in due to changes in season. The symptoms include insomnia, tiredness, loss of concentration, loss of appetite, low libido, etc.

Light therapy has been in use for quite a while and it has proved to help alleviate the symptoms of SAD and regulate the sleep-wake cycle.
