Waking Up Tired Despite Getting Enough Sleep? These Three Factors in Your Room May Be to Blame

Many people get enough hours of sleep, yet wake up in the morning without feeling rested or refreshed. A study examining the sleep habits of young adults suggests that the problem is not necessarily about too few hours of sleep, but rather the conditions of the room where a person sleeps.

The study identified three key room factors that can affect sleep quality: temperature, lighting levels, and noise levels. According to the findings, a disruption in any of these factors may be linked to poorer sleep quality, even when the total duration of sleep remains unchanged.

Room temperature is recognized in general sleep science research as one of the most influential environmental factors on sleep quality, as the human body typically prefers a somewhat cooler environment for sleeping compared to waking temperatures. Lighting and noise, meanwhile, affect the depth of sleep stages and the number of unnoticed awakenings throughout the night.

Feeling tired in the morning is not necessarily linked only to the number of hours slept, but also to the quality of that sleep — which explains why some people feel fatigued even after a relatively long night's rest.

The available report did not include additional details about the study's sample size, the institution that conducted it, or specific treatment recommendations.
