How Sound Affects Our Sleep

April 29th, 2018

We all have different preferences when it comes to the type and level of sound we choose to expose ourselves to when falling asleep. But it’s important to know which types of sounds are beneficial and which ones to avoid. Sound can have a significant effect on the quality of our sleep, and also on our general health!

One research review published in the Noise & Health Journal suggests studies show a link between night-time environmental noise exposure and cardiovascular disease; even low-level noises may have an impact due to the disturbance it can cause to your sleep cycle.

Even though we are seemingly oblivious to the outside world while we sleep, sound can still affect our resting brain. Noises that seem quiet and insignificant during the day can be extremely irritating when we hear them at night; they can interrupt our sleep cycles (even if you don’t consciously notice!) These noises can be anything from appliances, pets, people, storms or traffic.

Sounds such as breathing, whispering or ticking clocks are generally safe as they have little to no effect on the sleep cycles of most people. However, sounds such as conversations and background music could be considered dangerous due to sleep cycle disturbance and its association with cardiovascular disease risk.

While some people are more sensitive to noise than others, it is still important to make sure you sleep in a room that eliminates the possibility of being woken or suffering from a staggered sleep. Here are some of our best tips to eliminate noise for a tranquil sleep environment:

  • On low volume levels, white noise can create a gentle and consistent soundtrack to assist in the journey to sleep while blocking out other potential sounds. White noise is available on most sleep apps. For something a little different, try pink noise; a calming, slower version of white noise inspired by the sounds of nature with a “waterfall” effect.

  • If you have a partner who snores, invest in some noise-cancelling ear buds; they are inexpensive and effective
  • If possible, keep windows closed to block out traffic sounds. Double pane windows are a great way to block out street noise; if these aren’t a possibility, try installing heavy blinds
  • Turn televisions off or lower the volume before bedtime. Loud noises and artificial light directly before bed can stimulate the brain and cause sleeplessness
  • Turn your phone off or on silent before bed to minimise disruptions
  • Make sure your washing machine or dishwasher is turned off before bed
  • Pieces of furniture against the wall can sometimes act as a buffer to cut off sound between rooms; a tall bookcase is a great example
  • To cancel out noise from the outside, trees and shrubs have also been known to act as a sound barrier

If you have sound-proofed your bedroom to the best of your ability and are still struggling to achieve a healthy night’s rest, it might be time to invest in a new bed.
