The Effects of Sleep Deprivation

Everyone knows that a lack of sleep can make you feel grumpy and tired, but did you know that it can also have a serious impact on other aspects of your health? We take a look at some of the implications of sleep deprivation;

The Effects of Sleep Deprivation

Ages skin

It turns out your grandma was right – it really is important to get your beauty sleep! If your body does not get enough sleep, it releases the stress hormone cortisol which breaks down the protein collagen – this is what keeps your skin nice and smooth. As more collagen is broken down, fine lines and dull skin start to become more prevalent. Estee Lauder commissioned a clinical trial in 2013 which demonstrated a direct correlation between sleep deprivation and aging of the skin.   


Impairs judgement, memory and cognitive ability

Sleep plays a vital role in consolidating memories during the night, so if you are not getting enough it will be a lot harder to remember what you learned and experienced during the day.

Studies have shown that continuous wakefulness also has a strong debilitating impact on judgement and assessment processes which can lead to delayed responses in making choices and moral decisions.

Can lead to weight gain

When you’re feeling sleep deprived, your body produces excessive levels of ghrelin which is the chemical that tells you when you’re hungry. Your body also decreases leptin which sends satiety signals to your brain, this combination leaves you feeling hungry which means you are far more likely to reach out for the snacks. Studies have shown that there is an association between lack of sleep and obesity


Increases chances of depression

Sleep puts the body into a restorative state, so if you are not getting enough of it you are not allowing your body the chance to recover. This can lead to tension, irritability and fatigue which have the knock-on effect of reducing exercise, resulting in a vicious cycle of disturbed sleep and inactivity. Recent findings have demonstrated that loss of sleep increases the chances of a person reacting emotionally to a stressful situation


Increases chances of other health problems

Research has shown that people who consistently do not get enough sleep put themselves at an increased risk of chronic diseases such as diabetes, heart disease, mood disorders and poor immune functions. Poor sleep is also associated with decreased life expectancy, studies revealing that sleeping for 5 hours or less per night can increase mortality risk by roughly 15%.


Avoid sleep deprivation by using a sleep system such as the REM-Fit Sleep 400 Mattress and Monitor, which gives you control over your recovery time by allowing you to observe your sleep data and make the most of your rest. Understanding your sleep will help you to identify potential adjustments, intensify your recovery and enhance your performance.
