Daytime Sleepiness May Be Linked To Genetic Markers For Longevity

New research suggests there may be a link between a DNA marker for longevity and excessive daytime sleepiness – a condition that affects about 20% of the population. The most important genetic indicator for longevity are telomeres - little sections of DNA found on the end of chromosomes. Telomeres help protect the rest of your DNA, and shorten every time a cell divides. Therefore, shorter telomeres are associated with aging and cell damage, along with a heightened risk for cardiovascular disease, cognitive decline and even bone loss. On the other hand, longer telomeres are associated with biological “youth” and increased physical activity.

A 2017 study examined blood samples of 210 participants and found that those with excessive daytime sleepiness had much shorter telomeres, and a higher risk of heart problems. They also tested whether there was a similar result with those with sleep apnea - a condition that is also linked to both cardiovascular and cognitive diseases. However, it was found that participants with sleep apnea displayed longer than expected telomeres.

It is uncertain what the differences in telomere length actually means in terms of individual health, however the study lays the groundwork for taking daytime sleepiness just as seriously as sleep apnea, as the long term health risks can be life-threatening. The CPAP Clinic has a network of 40 clinics nationwide, and works in partnership with Centurion Healthcare, a Respiratory & Sleep Specialist clinic group to provide comprehensive sleep care including:

1. Respiratory & Sleep Specialist consultation – face-to-face and telehealth available
2. Sleep studies – in-lab, home and contactless sleep studies available.

Bulk billing available for specialist telehealth consultations as well as sleep studies. Medicare criteria apply. Call 1300 76 29 39 or email info@thecpapclinic.com.au for more information.
