Squeaks, beeps, thumps and all sorts of noises from household devices can be more than just annoying, they can also disrupt your sleep.
A study by researchers from the Institute of Aerospace Medicine showed that those sounds can have a negative impact on us when we sleep.
Sleep deprivation can potentially lead to decreased mental abilities, cause an irritable mood and cause other health woes.
The study says that sounds with sound-pressure levels of just above 33 decibels, which would be the equivalent of the normal noises in a rural town, have the potential to affect a person’s sleep.
This time of the year we are more prone to be affected by Seasonal Affective Disorder – or SAD.
SAD, also nicknamed ‘Winter depression’, can also cause a lack of concentration and anxiety and is very common in winter.
Nevertheless, some people can experience it in summer.
How much sleep do we need?
Most people need around 8 hours of good-quality sleep to function properly.
The NHS wars that as a general rule, if someone wakes up and still feel tired and “spend the day longing for a chance to have a nap”, it’s likely they aren’t getting enough sleep.
What causes Seasonal Affective Disorder?
The exact cause of SAD isn’t fully known. However, it is thought it is due to reduced, or even the lack of, exposure to sunlight.
The most important theory is that a lack of sunlight could stop a part of the brain properly, which can affect either:
- the production of melatonin (a hormone that makes you sleepy);
- the production of serotonin (a hormone that affects your mood, appetite and sleep; also linked to feelings of depression);
- Or the body’s internal clock.
