Improving sleep quality: Key factors for an optimal sleeping environment

A good sleeping environment is essential for restful sleep and therefore for our health and well-being. Key factors are good (room) acoustics, the right lighting and appropriate temperature regulation.

Did you know?


  • Noise has a significant impact on sleep quality.
  • Exposure to noise at night in particular can lead to a poorer quality of sleep - people to need longer to fall asleep and wake up more often.
  • Raised noise levels before going to bed and shortly before waking up can also impair sleep.
  • The use of white noise can help mask disturbing background noise and improve sleep.


  • Exposure to bright light, especially in the morning, has a positive effect on certain aspects of sleep. Balanced exposure to bright light in the morning can improve sleep quality.
  • Timing and intensity are crucial for optimal sleep quality.


  • The regulation of room temperature plays an important role in creating a comfortable sleeping environment.
  • A slight increase in body temperature in the evening and the subsequent reduction in body temperature due to the circadian rhythm make it easier for us to fall asleep, but also cause us to feel cold more quickly in the morning hours.
  • Slightly warming the room temperature during sleeping hours can improve the quality and duration of sleep
  • Excessively high or low room temperatures can affect the way we sleep by reducing deep sleep and overall sleep time.
