Health impacts of sleep deprivation

Sleep deprivation; most of us have experienced it at some point, but just how bad is it for overall our health and wellbeing? It’s easy to say we’ll catch up on sleep tomorrow, but lack of sleep can be doing long term damage to our bodies. Here are just some of the reasons you really need a good night’s sleep:

Health problems

We’ve spoken about this before, but we really can’t stress it enough. Lack of sleep has the potential to contribute to heart problems, high blood pressure, strokes or even diabetes. This alone should be all the motivation you need to head to bed that bit earlier tonight.

Ageing and weight gain

Puffy eyes and sallow skin tend to occur after a few restless nights, but research shows the results could be a lot more than this. The release of the stress hormone cortisol is the body’s reaction to not getting enough sleep. An excess of cortisol can actually break down skin collagen which is what keeps our skin smooth and elastic.

Just to make matters worse, studies show people who sleep less are more likely to gain weight. Tiredness can lead to an increase in appetite, particularly for high-fat, high-carbohydrate foods. ‘You snooze, you lose’ all of a sudden sounds a little more appealing!

Memory and concentration loss

We might want sharp concentration and a good memory, but if you’re not getting enough sleep, you can forget it (pardon the pun). Not only does sleep deprivation affect memory but it also impairs attention, alertness, concentration, reasoning and problem solving.


Research has shown that depression and insomnia can be interrelated. Sleep loss often aggravates the symptoms of depression, and depression can make it more difficult to fall asleep. On the up side, treating depression or insomnia can help decrease the symptoms of the other, and vice versa.

Here at Greywing, we want you to have a better tomorrow, but we also want you to live a better life. So do yourself a favour, get the recommended 7 – 8 hours of sleep tonight.
