I’ve had trouble with mattresses my entire life.
My parents lived through the Great Depression of the 1930s and were quite frugal.
My bed at home had an aged mattress that could be folded into a U shape to fit inside a metal frame that also folded. It developed a huge lump, so I had to maneuver around that to get a good night’s sleep. After college, I purchased a waterbed, but every night was like a stormy night at sea as the waves caused by my tossing and turning buffeted me about. I tried everything from mattress toppers, body pillows, and even sleeping on the floor but the solution came from an unlikely source, the HVAC unit. My HVAC unit cannot smooth out my lumpy mattress, but it supplies the one thing I had been lacking for good sleep. That was maintaining the perfect sleeping temperature of about 65°F. Our old house did not have central HVAC. We depended on electric blankets in winter as my father thought heating the bedrooms from our coal-fired furnace was a waste. We had one window AC unit for the living room and dining area but upstairs, we depended on fans or an open window to overcome the heat and humidity of summer. Scientific studies have shown that at 65°F, the sleeping body will cool itself with a process called vasodilation. Another technical sleep term is the circadian rhythm that is linked to the brain, light and dark cycles, plus the production of a sleep hormone called melatonin. I don’t care about any of that because my HVAC technician said that if I take care of my HVAC with regular cleaning and maintenance, then I will be able to sleep peacefully on my lumpy mattress for many years to come.
