How hot is extreme, you and I have now asked ourselves. Well, let me read aloud.
"as high as 45 degrees Celsius" (113 F)
"northern province [of Thailand] exceeded 44.1 degrees Celsius on Saturday" (111.4 F)
"Cambodia, Myanmar, Vietnam, India and Bangladesh, forecasters warned that temperatures could exceed 40 degrees Celsius in the coming days" (104 F)
"city of Mandalay could rise to 43 degrees Celsius" (109 F)
"It's very unpleasant and it takes the energy out of you."
Op ed: sounds nasty hot
You sleep on your side and stomach and use the same amount of pillow for both?? Stomach definitely needs the least amount of cushion, except for people who use no pillow I guess. And side sleeping has an entire shoulder's width of support to make up for. Totally different positions, you need an arsenal of pillows to really dial in the ergonomics.
