Do you have a hard time sleeping when you crank up the air conditioner?
Make sure the A/C’s vents are aimed away from your bed! That’s the recommendation of research published in the journal Energy and Buildings. The reason? Because when the blast of super-chilly air hits your body, it stimulates the nervous system, making you feel more awake and alert. It can also make you feel TOO chilly, which can actually make it much harder to sleep.
