Eeeek - I was just sitting out in the lovely hot sun (yes I am a sun worshipper and always have been though would probably be less keen if I wasn't on HRT) with my son drinking coffee and we were talking about sleep (he has a sleep app on his phone!) and I suddenly realised it's the longest day then too. After that, it always makes me feel a bit sad because it seems to take so long building up to the summer and as soon as it's there, the year is on the wane again - a relentless march towards winter - I expect you have a celebration Taz!
Meg - it probably depends what you have to do doesn't it - re the hot weather? I wouldn't relish a 5 mile walk in high humidity and hot sun, nor having to work somewhere without fresh air. Best to find ways to keep cool and happy if you can rather than worrying too much. Lots of cotton, few clothes, lots of fresh air, cool fans, cool bath/shower .....
