Sam Coles is the founder of Sam Coles Lighting Design Consultants, a residential and commercial lighting design practice based in Leighton Buzzard, and the guest on Episode 8 of The Healthy House Podcast, “Is Your Home Making You Tired? The Truth About Healthy Lighting.”

On the episode, Sam explains how light influences daily life at home far beyond how a room looks — natural light and colour temperature interact with the body’s circadian rhythm, shaping mood, concentration during the day and how easily the body winds down at night. She talks through the difference between warm and cool lighting and where each works best, common mistakes homeowners make with kitchen lighting, and how colour temperature and fitting choice affect glare and comfort.

A distinctive part of the conversation looks at lighting and sensory comfort for people with autism and ADHD, covering flicker, glare and how baffled fittings — which shield the bulb rather than leaving it exposed — can make a room more comfortable without cutting the amount of usable light. Sam also discusses lighting that adjusts through the day, echoing natural daylight patterns rather than running one fixed setting around the clock.
