Weather Swings.

The weather here on the south coast of England never really changes much. We get pretty mild winters and rather cool summers as a rule and all our weather tends to be dictated by mid-Atlantic pressure patterns which are rather ponderous. The only time you ever really get extreme variations in weather is when the wind changes and starts blowing in from the east, meaning we get cold Scandinavian air rather than the nice warm Atlantic stuff but that only happens rarely (Although the country goes to shit at the first sign of frost, let alone a full on snow storm).

As such, the weather seems to have very little effect on my personal health. I do sneeze when I walk out into bright sunlight which I've read is something to do with your sinuses but that's merely a temporary annoyance and easily rectified by carrying sunglasses.

Jam it back in, in the dark.
