ALLOW NATURAL LIGHT IN

Flooding your home with natural light is an important way to regulate your body’s circadian rhythm. “Natural light affects key hormones directly linked to the sunlight coming into our eyes and helping to shift our circadian rhythm,” Prof Greg Whyte, sport scientist and Olympian, says. Turner Baker has built at least two windows into each room of her own home – and encourages clients to choose “larger windows to bring in more daylight”.

Artificial light has a role to play, too. In Allen’s flat, he wanted to test LED lighting solutions to boost wellbeing, as well as save energy. “The lighting is all LED in classic pear-shaped bulbs with the warmest colour temperature commonly available (2700K),” he says. “It is electronically dimmed, which allows it to be dimmed down to almost zero – lower than candle lighting. This reduces the impact of blue spectrum light on our circadian rhythms at the end of the day.”
