Why summers are getting more humid and how that can be dangerous

I went to bed at midnight with a fan blowing cool air on me at 85% humidity & woke at 6 to 98% - 45 mins later it has fallen to only 95%. We're expecting a warm day of 27C (mid 80sF) tho in the past few weeks we've had days in the mid 30s, over 100F.

Since time immemorial When I got home from work or whatever, I always change into a housedress - but twice this week I've dropped sodden clothes into the hamper & had a shower. By the time I go to bed in this kind of weather, I often feel like I could benefit from another one!

In recent days skin cancer experts were warning people to cover up &/or keep out of the sun as record crowds flocked to beaches!!
