Tina has been having trouble falling asleep at night, and it is affecting her ability to focus in class. doing which of these things before bed would her get a better night's rest?

I believe the answer is: keeping her room cool

Being in high temperature environment usually increase the level of adrenaline and put your mood into anxiety.

Being in a cool room would bring your mood into a relaxed condition. This would help reducing the adrenaline level in our body, slow down your heart rate, and help you get into a deep sleep.

i believe the answer would be 1975.

hope this
