As a nation, 90 per cent of our time is spent indoors. That’s according to a survey by Nature Valley, which also revealed only 12 per cent of Londoners leave the office at any point in the day and 66 per cent of Brits only leave their chair to go to the toilet. All this is bad news for our mental wellbeing.
Too much time indoors can lead “to a range of problems for workers, including everything from seasonal affective disorder (SAD) in the winter months due to a lack of natural daylight, to sick building syndrome (SBS), especially in buildings with poor ventilation,” explains professor Charles Spence, experimental psychologist at the University of Oxford.
