Light the Way: The Role of Lighting in a Healthy Home

Light is a cornerstone of life, second only to water. As diurnal creatures, humans are naturally awake during daylight and rest when it’s dark. Daylight not only aligns our internal clocks but also influences digestion, emotions, and energy levels.

When we consider wellness in our homes, we often focus on physical elements like paints, carpets, and finishes, but lighting is just as vital. Natural light is so integral to our health that the World Health Organization includes access to adequate lighting as part of the human right to adequate housing. Without it, our physical and mental health can suffer.

Natural Light: A Key to Wellness

For our ancestors, exposure to sunlight was effortless, but in today’s built environments, adequate lighting requires thoughtful design. Biophilic design principles aim to reconnect us with nature, making natural light a central element of a healthy home.

To maximize natural light:

• Window Placement: North-facing windows provide consistent, indirect light throughout the day. East, west, and south-facing windows may require blinds or drapes to manage heat and glare.
• Skylights and Atriums: These are great options for brightening darker spaces but should be designed to avoid excessive heat or discomfort.

Artificial Light: Enhancing Our Built Environments

Since the days of cave dwellers and firelight, humans have sought ways to extend the day. Artificial lighting is essential for modern living, but it can disrupt our natural rhythms if not used thoughtfully. For instance, blue light from screens can interfere with sleep, and using bright lights in the evening may reset your circadian clock.

Lighting Tips for Different Spaces

• Bedrooms:

  • Use bright, daylight-spectrum lights for activities like reading or homework.
  • Dim lighting in the evening to mimic sunset and create a calming atmosphere.
  • Incorporate bedside lamps for softer, focused light.

• Living and Dining Areas:

  • Install dimmable lights to adjust for various moods—bright for gatherings and soft for relaxation.
  • Use pendant lights in dining areas to encourage slower, more enjoyable meals.

• Kitchens:

  • Include task lighting (e.g., under-cabinet lights) for cooking and food prep.
  • Match overhead and task lighting in color temperature.
  • Use dimmers to transition the space from functional to ambient for dining or entertaining.

• Bathrooms:

  • Prioritize bright, even lighting for safety and grooming.
  • Add decorative sconces or pendants for visual interest.
  • Consider night lights for convenience without disrupting sleep.

A Thoughtfully Lit Home

The foundation of a healthy lighting plan begins with abundant natural light, supplemented by adaptable artificial lighting to meet your needs throughout the day and across seasons. A well-lit home supports work, rest, play, and overall well-being—lighting the way to a healthier lifestyle.
