For a long time, I was like most people.
I would run my heating and A/C machine only during the day, and then when dusk came, I would turn the cooling component off, since it would be cooling down anyways.
I never actually thought that much about this schedule, I thought it was something that most people did. I have had sleeping issues for as long as I can remember, however ever since I was a teenager, sleep has often evaded me. I am lucky in the aspect that once I fall asleep, I can stay asleep and not have broken sleep like some people do. But falling asleep is the issue. Even with the most comfortable bed, I still find myself tossing and turning, night after night. I have tried numerous different medications, with varying success. However the medications always made me feel somewhat like a zombie, and so I just decided to deal with my sleep issues. This is when I learned how changing your hot and cold temperatures at night can improve your sleep. Particularly, running the a/c at night can truly improve your sleep. I used to keep my dial thermostat set to the high 70s, however after reading about how lower hot and cold temperatures can improve your sleep, I have started setting the programmable thermostat to the low 70s. I was amazed at the difference, the first night I fell asleep fairly particularly and slept through the rest of the night, for once, I woke up feeling refreshed in the day.
