Whether it’s blaring car engines out on the street or loud neighbours, we’ve all had to put up with a bit of noise pollution every now and then. Exposure to noise can cause auditory damage such as hearing loss. However, there are even more health problems due to noise pollution that can be observed when our sleep is affected at night.
Sleep is not only critical for daytime brain function, but it also plays an important role in allowing our bodies to repair and recover themselves from a hard day’s work, so that they can continue performing at tip-top condition.
The desire to block road noise has never been greater than when we are trying to get some sleep. Noise during nighttime disturbs our slumber and spoils the recovery phases of the human body. This could result in adverse effects. For example, it could impact the hormonal changes that regulate our glucose levels as we sleep, which would lead to reduced glucose tolerance and increase the risk of type 2 diabetes (Tasali et al, 2007).
