We tried everything.
Then I went to Japan.
After my wife turned 47, she started experiencing hot flashes and night sweats that disrupted her sleep. We tried lots of things but nothing seemde to truly help.
The answer turned up somewhere I wasn't looking. While working in Japan, I saw a mattress cover made for the hot and humid summer nights there. It was used to manage body heat and moisture, not simply cover up the mattress.
I got one for my wife. She slept better. That was the beginning of a journey to create better sleep products for ourselves and others going through this stage of life.
