While many people focus on all of the internal things going on when it comes to sleep issues, it is also important to remember the external ones, as well. Your room plays a large part in your sleep. And there are two components that are the most crucial:
1. Temperature - Having your room set to a cool setting is HUGE! Sleep.org suggests a temp between 60 and 67 degrees. Since our bodies naturally reduce in temperature for sleep having your environment help with that can lead to better sleep.
2. Darkness - Keeping the room dark will help your brain begin it's shut down process to initiate sleep. Things like bedside lamps, tvs, and phones introduce light and that can keep you from restful sleep. Some studies suggest stopping electronics 30 minutes prior to sleep because even after we stop engaging with the electronics, our frontal cortex isstill firing and that can impede sleep.
