Yes - feel run down the whole of winter. I put it down to SAD - https://www.nhs.uk/mental-health/conditions/seasonal-affective-disorder-sad/overview/Without wishing to turn this into Mumsnet - does anyone else find that they're just constantly bloody ill from ~October till April every year?
Colds, sore throats one after the other... As soon as it warms up, all is well.
I guess having small kids doesn't help, but I do shed loads of exercise and have a healthy diet so not sure what else I can do?
