Among the given options, hearing housekeeping workers is the most likely environmental factor to disrupt rest and sleep due to noise pollution. Noise can interrupt falling asleep and contribute to frequent awakenings, which are factors in insomnia. Good sleep hygiene includes a quiet and comfortable environment, as emphasized by the National Institute of Health.
In considering factors in the environment that are most likely to cause problems with rest and sleep, among the options provided, hearing housekeeping workers is the most probable disruptor. This is because noise pollution is a common detractor from sleep hygiene. Noise can interrupt the process of falling asleep and also lead to frequent awakenings, which are both aspects of insomnia. As per recommendations to improve sleep quality, creating a sleep-conducive environment is critical, which typically means reducing noise. Using a white noise machine is an example of an attempt to mask disruptive sounds and thus would not be the answer here. Conversely, items like cool sheets and sleeping alone do not necessarily disrupt sleep and might even be preferential depending on individual comfort and habits.
It is important to note that both the National Institute of Health and sleep studies emphasize the importance of maintaining consistent sleep habits and a quiet, comfortable sleep environment as part of good sleep hygiene. Furthermore, for those facing sleep challenges, it is advisable to seek medical advice to explore treatment options, including lifestyle adjustments and possibly the use of melatonin supplements.
