Good Weather to sleep

Sometimes then the weather is very dull, one feels the same. I don't know how the body adapts to the change in weather. Today the weather is horribly "english". Seriously, if London sports this kind of weather for most days, I am not going there. Temperature around early 40s, cloudy and raining interemittenly. Whatelse do you want to call it a bad day, when going outdoors is a big PIA. I guess the transition from good sunny summer weather to winter is most torturous. Once you get used to the gloomyness in the atmosphere, then it doesn't affect you that much.
BTW, heard of the song Gloomy Sunday ??
