When the weather got hot overnight, the house central air conditioning couldn’t cool the whole house right away. A sudden drastic change in temperature is always a strain on the house’s electrical systems and equipment.
So, for a couple of days while the A/C worked to get the house cooled, I used a small room fan to cool the bedroom at night. It is amazing how the fan can put you right to sleep. They call it white noise, and I can’t remember falling asleep so quickly and soundly in a very long time.
