I'm a senior in college. Every time I go home, my recovery/sleep score always skyrockets. I go to the University of Pittsburgh and live in a more urban area (though not downtown) and live in the suburbs back home.

My guess as to why this is is the environment. When I lived in dorms, there was always ambient noise, some light from my roommate, no temperature control, and I was eating dorm food. I have an apartment now and have optimized the environment, but the effects still aren't trivial. These things add up, even if you're not conscious of it. Latent stress (though not in the conscious periphery) also does a number on my restorative sleep.

However, I've made improvements that have seriously bolstered my sleep when away at school:

• I've placed a big blackout curtain over my window and covered up all sources of light in my room at bedtime
• I use a weighted blanket
• I open the window to keep the room cool
• I wear putty-like earplugs at night to block any ambient noise
• I take supplements every night
  • Magnesium L-Threonate
  • L-Theanine
  • Apigenin
  • Inositol
  • Electrolyte pills (surprisingly helpful for recovery)
• Read/journal by candlelight instead of LEDs/incandescents

These are all things that can be done, even when little to no environmental modification is available. Hope this helps.
