Sleep is your biggest protection right now

A well-rested sleep has many benefits and University of South Australia sleep experts are reminding people that it’s rest they need to stockpile sleep to keep their health on track during this madness.

UniSA sleep and fatigue researcher, Dr Raymond Matthews says prioritising sleep will help protect you from COVID-19 by boosting your immune system.

As the reality of Covid-19 steps up, people are rightly more vigilant with handwashing, social distancing and working from home if they can. But what they may not realise is how important sleep is to their overall health,” Dr Matthews says.

“Sleep plays a vital role in the function of the body’s immune system. When people suffer from a lack of sleep, they’re reducing their body’s natural killer cells – the white blood cells that hunt down virally-infected cells – which means they may be compromising their immune system and increasing their risk of getting sick

“This is vital information for all people – not only those who are staying up late to catch up on the latest Covid-19 updates, but most importantly for our front-line health care workers who need sufficient sleep to rest, recover and stay healthy.”

By having a healthy sleeping pattern, we are protecting ourselves from infections, a restored body and helping us all cope mentally. “Many studies show an increase between short sleeps and increased mortality,” Dr Matthews says.

“One study found that a lack of sleep reduced the effectiveness of the influenza vaccination by half, indicating just how important sleep is for producing the necessary antibodies requires to fight infections.

“Looking forward to when we discover a vaccination for COVID-19, we must also ensure we have sufficient sleep for it to work well.”

Dr Matthews has given a bedtime basic guide on helping us to have a good sleep by:

avoiding cigarettes, caffeine and alcohol
choosing light, rather than heavy meals in the evening
keeping your bedroom dark, cool and quiet
avoiding bright light in the evening and making sure you get enough sunlight in the morning
exercising during the day

Every movement counts during this time and we need to know that we are all in this together.
