3 Surprising Causes of Poor Sleep Quality (And How to Fight Them)

Why do complex living creatures, by and large, require sleep? Wouldn’t it have been prudent that nature assembles creatures which only require nutrients and air to fuel their energy, and all in order to keep the fauna as productive as possible?

As it appears, we do not have a lot of saying in whether sleep is necessary for our functioning. The following 5 surprising causes of poor sleep quality only go to prove this by triggering a cavalcade of terrible symptoms, so here’s how to fight these causes for an improved quality of life.

Blue-light insomnia is a modern ‘plague’

It is one of the most prevalent issues of our modern age. Medical professionals discuss it extensively and many networks cover its impact, so it is still quite baffling that so many people stand it utter bewilderment after you tell them that their monitors cause blue-light insomnia. Of course, they have all heard that vibrant images on a tablet screen keeps them awake, but most of them consider that they’ll be able to doze off as soon as they turn them off. This is a grave mistake.

The medical community has uncovered with utmost confidence that computer, smartphone, and tablet screens emit a blue light which functions as a melatonin suppressant. Melatonin is a crucial sleep-inducing hormone which prompts us to bed when the time is ripe, and its production can be delayed by three or four hours after the screens have been turned off.

In order to battle this properly, you need to employ a strict turn-off policy for all the screens in the household at least two hours before your designated bedtime. In fact, you should probably turn off your Wifi as well, in order to ensure that you are not tempted to just pick the phone up and start browsing in bed.

Allergies are a latent sleep nuisance

The most common symptom of allergies that affects our sleep quality is rhinitis. In fact, if you are sensitive to any kind of an air-irritant, you can end up with complete congestion or a swelling of a nasal airway, which further leads to mouth breathing and snoring.

It has been known for countless centuries that blocked nasal airways lead to, at the very best, light sleep and, at the worst, to dire health complications. Halitosis, or bad breath, is the least of it. Mouth breathing can set you up with chronic throat and ear infections and periodontal disease – the types of ailments that trigger a domino effect which ends with cardiovascular issues.

Thankfully, the latest generation of mouth strips helps keep your mouth closed without causing additional irritation to the skin, and they also enable mouth breathing if it is absolutely necessary. In addition, the latest antihistamine sprays are most effective ameliorates of congestion so you might want to look into them if you have a chronic allergic issue.

Keeping your adrenaline up will make you sleep better

You need to calm down in order to get sleepy, so the apparent logic dictates that individuals who lead sedentary lifestyles have absolutely no issue with hitting the sack. Of course, this is a fundamentally wrong assumption.

The sedentary lifestyle has adverse effects on our bodies in general, this is a well-known fact, but there is a deeper, more severe effect of this on our circadian rhythm and sleep cycle. When avoiding physical exercise turns into a habit, it leads to negative mood, a change in disposition, a melancholic outlook on life and sleep disorders. (Anxiety, as such, is one of the elemental causes of poor sleep quality as well).

A study from 2012 indicates that regular exercise can improve quality of life and even reduce the symptoms of insomnia and sleep apnea. Furthermore, burning your calories and spending energy through rigorous excretion, which is what our bodies are fundamentally made for, can aid in the stabilization of your sleeping patterns in general.


While scientific research has uncovered a lot about sleep-related biochemical cycles and its psychological impact, we are still inconceivably far from answering why we require it. It is a fundamental question that may unlock the greatest secrets of our very nature, but up until then, we’ll have to stay content with learning more about the sophistication of our minds and brains. The steady trickle of discoveries constantly reveals the new causes of poor sleep quality and, subsequently, solutions that help us sleep better.
