A sleep environment refers to the physical space where a person sleeps, which can significantly impact the quality of sleep. Key factors include mattress comfort, bedding materials, and room temperature. A dark, quiet, and cool room is generally considered ideal for promoting restful sleep. Additionally, the presence of noise and light can disrupt sleep patterns. Using blackout curtains and white noise machines can help create a more conducive atmosphere. Personal preferences, such as the arrangement of furniture and the use of aromatherapy, can also enhance the overall sleep experience.
