Why poor quality sleep is bad for your body

Have you had a bad night recently? We’re sure you have at some point. You probably didn’t feel great the next day – a bit down, unable to concentrate and dog tired by the time you got home from the office.

Poor quality sleep has a nasty effect on your body. If it happens too often you put yourself at risk for many things such as chronic diseases, depression, accidents and it’ll even kill your sex life. Nobody wants that!

Chronic disease

We’ve discussed the risk of diabetes in our post on chronic illness and poor quality sleep, however poor sleeping puts you at risk of more than diabetes.

Your risk for chronic conditions such as hypertension and heart disease increases when you suffer from insomnia or other sleep issues such as sleep apnoea. According to the Sleep Foundation in the US, one study showed that men with sleep apnoea (obstructive airflow) have a 58% higher chance of developing heart failure (over an 8-year period).  Yikes!

Depression

On any given day after a rubbish night’s sleep, it is difficult to feel zooty and joyous. There are many studies and research that show a definite link between insomnia, depression and anxiety.

Although it is a complicated link, it is certainly there. Again as mentioned above, sleep apnoea can cause depression. One study found that of the 19000 people studied, those with the condition were a whopping five times more likely to suffer from depression. According to Psychology Today, sleeplessness alone causes higher rates of the development of depression.

Focus

If you’re suffering from a sleep disorder, you’ll no doubt, know that concentration can be difficult.

On WebMD scientists state that ‘sleep deprivation leads to lower alertness and concentration.’ In turn, this hampers your ability to complete tasks, pay attention and retain information later on. Let’s not mention the fact that you become worse driver as your reaction times are slowed – much like when you’re a little tipsy.

The added effect of underperformance in the workplace because of insomnia or another sleep disorder, is, naturally, stress. Coupled with the fact that sleeplessness causes an increase in your stress hormones, it’s like a double whammy.

Sex drive

Oh yes! We said it. There goes your ‘other’ bed time activity. Never mind the lack of energy to get in the mood; your sex hormones actually take a knock too. Another double whammy.

The Asian Journal of Andrology states that, “Various disorders of sleep including abnormalities of sleep quality, duration, circadian rhythm disruption, and sleep-disordered breathing may result in a reduction in testosterone levels.” Not great news for men – especially since sleep apnoea is more prevalent amongst guys.
