It’s well known that a poor night’s sleep affects our functioning the next day. But, the long-term impact of lack of sleep might surprise you. In this article, a health professional shares how she’s seen inadequate sleep affect her patients’ health, beauty and relationships.


Sleep and health

How does sleep affect your health?

“Rest is essential to growth” says Registered Nurse Jenny Matheson, who spent 20 years working in intensive care units where she saw how important sleep really is. “I cared for a patient who had to have a liver transplant. He had sleep apnea for years and what happened was he did not get enough oxygen to the artery that supplies his liver while he slept.”

Jenny now works as a Snoring Specialist with Specialist Clinics of Australia. She says that when it comes to getting your 8-10 hours nightly, it really isn’t quantity that counts, it’s quality. A person who sleeps soundly without disturbance may be alright with a minimum of 6 hours, but a light sleeper who wakes easily or sleeps with disruptions, such as snoring or sleep apnea, will need much more sleep.

We sleep in cycles and go into deep REM sleep a few times throughout the night. It’s during this REM stage that our bodies replenish vital hormones and enzymes, carry blood and oxygen to necessary sites, revitalise organs, and generally repair themselves.


Beauty sleep

How does sleep affect your looks?

It’s not just your health that gets affected by sleep, but your looks as well. Your body increases the amount of blood flow to the skin while you sleep, which nourishes the skin, reduces dark spots and even helps your skin rebuild collagen (that essential ingredient for plump, youthful-looking skin).

More blood can also flow to your hair follicles while you sleep, which gives them the essential nutrients that keep your hair healthy.

When you don’t sleep enough, your body is also more likely to release stress hormones, which can cause hair loss and tension in your facial muscles. They really do call it “beauty sleep” for a reason.


Sleep and relationships

How does sleep affect your relationship?

The most astonishing issue that Jenny sees in patients who don’t sleep enough is the breakdown of relationships. It’s not just that lack of sleep causes irritability and friction, but it also causes difficulty concentrating, which means that you and your partner may not be listening to each other. Without realising it, you could be missing important and even emotional points in your conversations. Does the line “you don’t even listen to me!” sound familiar at all?

“For some patients, it leads to divorce,” Jenny says. Some of her patients sleep in a separate room to their partner because of their snoring. Their partner gets more sleep and the friction goes away, but sometimes, so does the intimacy. These patients often describe how their relationship shifts from being partners to being flatmates.  However, if sleeping in different rooms suits your relationship, then do what works for you.

“It is a big issue in the community,” Nurse Jenny says of lack of sleep.  Last year, inadequate sleep was estimated to cost the Australian economy over $66 billion.


There are plenty of habits and lifestyle adjustments that can help you improve your sleep, but most importantly, you have to make an effort to make sleep a priority in your life, and seek professional advice when needed.
