“Winter is viewed as a gloomy inconvenience and, rather than getting outside to reap what little daylight there is, we switch the lights on and crank up the central heating instead. This may be detrimental to our mental health: exposure to bright light, particularly during the early morning, is a tried and tested way of combating the winter blues. Similarly, many of us keep the lights and heating on long after the sun has set and spend these already brightened evenings in front of electronic gadgets, which produce yet more light. This may undermine our ability to get a decent night's sleep.” SleepWinterWinter Blues Book:Chasing the Sun: The New Science of Sunlight and How it Shapes Our Bodies and Minds Source: Chasing the Sun: The New Science of Sunlight and How it Shapes Our Bodies and Minds
