Sleep and Immunity

How a good night’s sleep can boost your health.

It has been scientifically proven that sleep gives us more energy, clearer judgment and, most importantly, stronger immune systems.

With the uncertainties the world is currently facing, it is now more vital than ever to understand the importance of sleep and how it can improve the health of you and your families. Here are the most important tips and facts to improve your sleep health.

Ensure you are getting enough sleep


One in four Australian are sleep deprived, and are regularly failing to get their required amount of sleep. 

Without sufficient sleep, our bodies are unable to produce protective proteins, which leaves the door open to a variety of infections and inflammations. In turn, sleep deprivation may reduce the effectiveness and responsiveness to vaccines.

Studies have shown that people who sleep eight hours per night develop stronger immune systems and the ability to recharge and learn new things the next day.

Sleep creates stronger cells


To fight illnesses and infections, our bodies create special types of protein called cytokines. Cytokines are produced and become active while we are asleep, fighting off inflammations while we get our shut eye.

Because of this, research has shown that those who go without sleep produce significantly less protective proteins than those who slept. In turn, staying awake allows your stress hormones to run wild, reducing the potential impact cytokines have on your body.

Maintain a healthy bed environment


Though we may change our pillowcases and bed sheets often, our beds can be home to a variety of unpleasantries, including dust mites, dead skin, mould and fungi.

This can pose health issues for those susceptible to allergies and weaker immune systems. It is recommended that you replace your pillows every 12-18 months to reduce the level of contaminants.

Furthermore, investing in a good quality mattress protector and occasionally cleansing your mattress, either via a deep clean or vacuum, may help reduce the amount of infectants present. 

Changing your sheets every week also reduces dust mites and other allergens, which will give you a better night’s sleep.

If you share a bed with someone who may be ill, it is recommended to sleep in a separate room and mattress that has not been recently used.
