The Dangers of Sleep Deprivation

We all know the importance of sleep. When we don’t get enough shuteye, we get tired, cranky, and our ability to focus deteriorates. Despite this, many of us continue to ignore it. It is no wonder, given how difficult it is for many of us to take a proper break even during our waking hours.

It largely comes down to behavioral health, or how our behaviors impact our physical and mental wellbeing. But do you know why getting enough quality sleep is so important? The immediate aftereffects that come from a lack of it may be enough to persuade you. But, first, let’s delve into the dangers of sleep deprivation.

Sleep deprivation brings an onset of problems such as impaired cognition, a higher chance of stroke, an increased risk of heart disease, breast cancer, and diabetes, and a hormonal imbalance that can lead to weight gain. Let’s take a closer look.  

Impaired cognition, worsened mood and anxiety

Lack of sleep impairs our memory and ability to process information. It also disrupts the neurotransmitters to our brain which regulates our mood. Our brain’s anticipatory reaction also gets raised, increasing our overall anxiety levels. 

Increased risk of stroke, heart disease, diabetes, and breast cancer

In addition, getting less than 6 hours of sleep on a regular basis increases our risk of stroke by four times. Sleep deprivation also raises blood pressure, cortisol, and norepinephrine levels.

Elevated blood pressure increases the risk of heart disease, whereas the latter two are linked to insulin resistance, which leads to diabetes. 

Melatonin is the hormone in our body that regulates our sleep-wake cycles. When we expose ourselves to light late at night on a regular basis, it decreases. This interferes with the production of oestrogen, which can lead to breast cancer.

Weight gain

According to sleepfoundation.org, a large number of studies have shown that insufficient sleep and poor sleep quality can lead to weight gain and an increased risk of obesity. Other chronic health conditions, such as metabolic disorders, are also a risk. 

Sleep helps to restore balance to the hormones that influence our satiety levels. Being awake for longer than you should also naturally increase your window of time for eating, which can cause weight gain. This is particularly true if you are eating late at night.  

Getting good, sufficient sleep allows you to take on the day and be the most focused and productive person you can be. It gives you a clear mind, a stronger immune system, a better mood, a sharper brain and a healthier heart. Remember that consistent good sleep, along with exercise and nutrition, is one of the three pillars of health.
