Sleep - a crucial pillar of health

Ah… the ever-so-popular topic of sleep!

Something we do every night, yet clouded with uncertainty still for many.

I thought I would share every few days some of the key things that affect our sleep. With the hope it might help tweak any habits you may have to maximise those essential hours of slumber. 💤

But first perhaps we should quickly look at why it so important?

Sleep is a crucial pillar of health. Here are a few key reasons why.

#1 – Improved moods 😄

This should not come to a surprise to anyone. I am sure most will have noticed how much better you feel after a good night’s sleep. An increased feeling of optimism and a bounce in your step 🏃‍♀️. Prolonged sleep deprivation has been shown to increase irritability and anger and has been closely linked to mental health conditions such as anxiety and depression.

#2 – Improved immune function 💪

Especially important during these times, restorative sleep has been shown to greatly enhance our immune function. During the deep-sleep phase, immune cells peak and our body has a chance for growth and repair. One study showed those that slept less than 7 hours at night were nearly 3 times more likely to develop a cold than those sleeping 8 hours or more.

#3 – Less tendency for weight gain 🏃‍♀️

A regular lack of sleep has been associated with weight gain and obesity. The regulation of two key appetite hormones - ghrelin and leptin – can become disrupted leading to an increased appetite and a tendency to eat more during the day. Plus when we are tired, our motivation to exercise naturally decreases, so we burn less calories.

#4 – Enhanced mental and physical performance 🎓

Lack of sleep makes it harder for most to concentrate and retain information. Productivity and performance naturally decline. Creativity tends to be stifled. Making it very difficult to achieve your full potential at work or at school. This applies to physical performance as well. Endurance, reaction times and recovery are all improved with a strong sleep hygiene.

#5 – Reduced risk of chronic health conditions 🏥

Prolonged sleep deficiency has been linked to a myriad of chronic health conditions such as type 2 diabetes, cardiovascular disease and stroke.

Hope everyone has a lovely weekend and stay tuned for ways to help improve your sleep soon.
