Heavy snorers could potentially receive thousands of pounds of extra income in retirement simply by declaring their underlying condition when buying an annuity.
MGM Advantage found that people who have sleep apnoea, of which heavy snoring is a symptom, could boost their pension pot by £12,000, resulting in a significant amount of extra income each year.
Around six million people aged over 65 have been diagnosed with sleep apnoea in the UK, according to the study.
The retirement income company calculated that a man who has sleep apnoea could make £571 extra each year above the current highest conventional annuity rate available in the market. This could lead to a £12,000 pension income boost over a typical retirement period of 21 years.
"If you are a snorer, you're highly unlikely to tell many people but, when thinking about your retirement and purchasing your annuity, it's something to make very clear," said Andrew Tully, pensions technical director at MGM Advantage.
"Sharing that little bit of information could mean a difference of thousands of pounds of extra retirement income."
An enhanced annuity pays a higher annuity rate to individuals with particular lifestyles, including smokers and the obese.
Providers of such annuities do so because they take the view that people with these lifestyles are less likely to live as long as those who don't.
Other conditions which are likely to result in a higher income through an enhanced annuity are diabetes, angina, high blood pressure and high cholesterol.
However, conditions do not have to be well-known illnesses, although people must provide proof that they suffer from them, which would mean being clinically diagnosed.
Retirement may seem like a long time away for many of us, but the best way to make sure we're adequately prepared for older life is to start saving into a personal pension as early as possible.
This will give your fund time to grow, meaning you will be able to afford a better standard of living when the curtain comes down on your working life.
But also keep in mind the auto-enrolment scheme which came into effect on 1 October. This means workers will be automatically placed into company pensions, so it is important to find out how it will affect you.
