The January blues are well documented but aside from the usual clichés which abound around this time of year, there is some evidence of the impact of winter on people’s mental health and wellbeing, According to a new survey from Peldon Rose over two-fifths (44 percent) of employees say winter has a negative effect on their mental wellbeing, half (51 percent) believe it adversely affects their mood and 30 percent state winter affects their productivity. Over a third of respondents (35 percent) even identify themselves as suffering or having suffered from Seasonal Affective Disorder (SAD) – a type of depression that becomes more severe in the winter and three-quarters (76 percent) have experienced or are currently experiencing stress in the workplace. But the report concludes, effective workplace design can help combat some of these ill effects.
