Being able to enjoy natural light is something very beneficial for our health. In fact, a recent survey reveals how the 82% of Spaniards claim that natural light influences their mood. This study also shows how more than half of Spaniards believe that natural light influences sleep quality, affecting their productivity as well.

This global survey is part of a report that highlights the importance of living in healthy homes and the small changes that can be made to improve living environments and daily exposure to natural light. The initial findings of the report The Indoor Generation have revealed that, approximately,one fifth (18%) spends most of the day in indoor spaces, between 21 and 24 hours.

This study supports the World Health Organization's research documenting that we spend up to 90% of our time indoors, away from the life-giving sources of nature.

As the days become shorter and colder, the importance of getting enough natural light becomes, without a doubt, essential. A report published by the National Research Council (NRC) of Canada, suggests that the inhabitants of Western countries may not be having adequate exposure to natural light and this could be detrimental to their health and well-being.

  • Remove light from outside to enter the bedroom at night.
  • Sleep in a cooler room.
  • Avoid electronic devices that emit blue light (television, smartphones, tablets) before going to sleep, because it can trick the brain into staying alert at the wrong time.
  • Establish a good routine when going to bed: better read a book instead of spending more time in front of a screen
  • Give children a red or orange night light if they are afraid of the dark, since they are the ones that interrupt sleep the least.
