As you can see from this graph, the humidity rose to 80% by midnight and peaked at about 7am this morning.
We run the air conditioning in the bedroom during the evening until we are ready for bed, then we switch it off and leave the ceiling fan to circulate the cool air throughout the night. That normally gives us a pleasant night’s sleep.
This morning though I woke up at about 6am, not wringing with sweat but still not 100% comfortable. I did manage to get back to sleep after turning my pillow and then slept until 8:45 which is very late for me!
