The shortest day of the year is just around the corner. There will be eight hours forty-nine minutes less daylight on Wednesday 21st December than on the summer solstice.
These shorter days (less than eight hours of daylight during virtually all of December) and darker evenings are also often cold and wet, or just depressingly grey. So it’s hardly surprising that we are tempted to snuggle up and stay indoors, eating comfort foods and being less active. Even though we know that this centrally heated, electrically lit, stuffy environment is absolutely no good for us.
