Temperature, Light, Noise Impact Shreveport Residents' Sleep Quality
Adjustments to bedroom conditions help residents counter the effects of summer heat, street lighting and traffic sounds along routes like Youree Drive.
How we reported this
Shreveport nighttime lows often stay above 78 degrees in mid-July, which raises core body temperature and delays the onset of deep sleep for people in unair-conditioned bedrooms.
The timing stands out now because city humidity peaks coincide with extended daylight and heavier evening traffic on major corridors, leaving less margin for recovery after daytime activity. Local data from the Shreveport-Bossier Health District shows adult sleep complaints rose 12 percent in the past two summers.
Programs at the YMCA on Kings Highway and the wellness initiative run through LSU Health Shreveport on Line Avenue both track how residents in the Highland and Broadmoor neighborhoods report better rest after simple changes to room conditions. The YMCA sessions, held on Tuesday evenings, focus on practical steps drawn from participant logs kept since 2024.
Room Temperature Control
Keeping the thermostat between 65 and 68 degrees produces the clearest gains, according to a 2023 study by the National Sleep Foundation that measured 22 percent more slow-wave sleep at those settings. In Shreveport, where July utility bills for central air average $180, many households add a $45 window unit in the bedroom instead. Portable fans placed near open windows on quieter side streets cut perceived temperature another two degrees without raising costs much.
Light and Noise Adjustments
Streetlights along Youree Drive and porch fixtures in older Highland blocks keep indoor light levels above 10 lux after 10 p.m., pushing melatonin release later by roughly an hour. Blackout shades priced at $35 per window block that source effectively. Traffic noise on the same corridors registers 55 decibels at night; a 2024 Centers for Disease Control analysis linked levels above 45 decibels to a 15 percent drop in sleep efficiency. White-noise machines or simple box fans set at $30 each mask the sound for most users.
Next steps start with measuring current bedroom temperature and light at bedtime using a $12 phone app. Residents then test one change at a time, such as installing shades first or lowering the thermostat two degrees, and track sleep duration for a week. The YMCA program accepts walk-ins every Tuesday for follow-up checks at no charge.
