Are You Getting Your Best Beauty Sleep?

Are You Getting Your Best Beauty Sleep?

Written by our in-house Naturopath, Holistic Nutritionsit and Medical Herbalist Emma Gibson, from Nala Holistic

In today’s glamorised fast-paced and full lifestyle, many of us have been led away from prioritising (let alone promoting) the quantity and quality of our sleep. And, the factors that can disrupt our natural sleep-wake cycles are on the rise.

Poor quality sleep can affect how we think and feel, how we show up to others, mental and physical performance, and in the long-game it can contribute to the development of ill health and dis-ease. In other words, sleep is critical to our mental and physical health and performance, now and cumulatively in the future… and let's be honest everything feels better when we’re sleeping well.  

Read on to learn more about the sleep-wake cycle, why sleep matters, what's disrupting it, and 5 simple ways we can regulate our circadian rhythm and promote restorative rest daily. 

What is the circadian rhythm? 

The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. It's often referred to as the "body clock" and is influenced by external factors such as light and darkness. The circadian rhythm plays a crucial role in determining when we feel alert and awake during the day and when we feel sleepy at night.

The circadian rhythm not only affects sleep patterns but also influences various biological processes such as hormone production, body temperature, metabolism, and cognitive function. Disruptions to the circadian rhythm, such as shift work, jet lag, or irregular sleep schedules, can lead to sleep disorders, mood disturbances, and other health problems.

Why does sleep matter?

While we are sleeping, the brain and body slow down and focus primarily on rest, recovery, and repair. What happens during sleep has far-reaching effects on all of our core body processes. 

Each phase has its importance, from processing memories to building emotional resilience, critical growth and repair of our cells and tissues, the brain is flushed of any residual debris, and the body systems are supported in their optimal functioning. 

Body Temperature

Morning waking is largely driven by a natural increase in core body temperature, which (along with light exposure) stimulates a rise (and ideally peak) in cortisol. How can we optimise that body temperature piece? Get into cold water for 1-3minutes in the morning. This might be an ice bath, but can also just be a cold shower OR dip in a nearby body of water. Why cold? Because your body will adapt by increasing core body temperature. 

Light Exposure

AM: One of the most powerful things you can do to regulate your sleep-wake cycle is ensure exposure to bright natural light, first thing on waking (or at least within 30-60 minutes), for at least 5-10 minutes. This sends a clear signal to the brain to increase cortisol, essentially sets an internal timer to encourage sleepiness at the end of the day, and washes away any lingering melatonin. If you struggle getting to sleep at night, try this! 

PM: It is critical we take a look at our use of backlit devices in the evenings and assess whether it is urgent or necessary to use these so close to sleep time. Backlit devices are not bright enough to elicit the same morning cortisol response above BUT they are bright enough however to disrupt your sleep if used before bed by suppressing melatonin production. Aim to turn off your devices at least 1-2 hours before you sleep.


AM: Having a nourishing morning meal, ideally protein-rich, supports your biological clock by waking up your metabolism and increasing alertness earlier in the day. Our faves are a protein powder smoothie or omelete. 

PM: Eating an excessively large meal in the evening or too close to bedtime (2 hours or less) can also disrupt sleep. Aim to have your last meal at least 1-2 hours before bed. TIP! If you feel you need something after dinner, Bone Broth is a nourishing protein-rich hug in a cup, rich in the amino acids that help us produce melatonin, our sleepy hormone. 


Among its many benefits, movement increases core body temperature and makes us feel more alert. Earlier in the day, this is great! Later in the day, it can delay sleep onset. 


Coffee has a 5-8 hour half life, meaning that whether you feel its alertness effects or not, if you go to bed around 9.00pm and have had a coffee after 2-3pm, half of that coffee is still in your system and WILL affect the quality of your sleep. Genes, medications, and other individual differences can mean for an even slower processing time. It does this by directly interfering with your natural sleepiness substance (adenosine) in the brain.
