We don’t know how readers in the rest of the world are doing but here in the UK we are slap bang in the depths of the British Winter, which means cold, damp and dark. There’s little doubt that this time of the year can get on top of people a little bit, leaving them feeling blue and that one of the most widely recognised causes of this is seasonal affective disorder (SAD), which is directly linked to the lack of natural light we experience during the course of the day. SAD can affect each of us in different ways and to varying degrees but it is a common condition linked to the functioning of a part of our brain called the hypothalamus which controls our moods, appetite and sleep patterns. Lack of light affects us by interfering in the production of feel good hormone serotonin and disrupts the melatonin hormone and circadian rhythms that regulate our sleep.
