It may not seem like a big deal to lose an hour of sleep here and there, but have you ever considered what that amounts to over the course of a month? A year? Or even your lifetime?

The Lost Sleep Calculator from Hillarys is an eye-opening tool that measures the long-term impact of lost sleep, using a person's age and the amount of sleep they had the night before. For instance, sleeping for around six-and-a-half hours every night — 90 minutes less than the recommended eight hours — amounts to an astonishing eight years of lost sleep in a lifetime.

So what is keeping us awake?

In 2020, Hillarys surveyed 2,550 people about their sleeping patterns, revealing that the most significant physical factor that impedes our sleep is outside noise, followed by a fidgeting or snoring partner. Sixty-two percent of respondents felt their sleep was affected by the family cat or dog jumping into bed (although a reassuring 38% slept better when snuggled up to their pets.)

Aside from these physical disruptions, persistent thoughts about arguments, work, social media and the impending sound of the alarm also kept people awake. The Lost Sleep Calculator takes these statistics into consideration to estimate how many hours of lost sleep you can blame on a partner or thoughts of the workplace.

What can we do about our lost sleep?

Considering that the outside world is the main source of our sleepless nights, there are simple things we can do to buttress our environment.

Hillarys' Lucy Askew says, "If you find you're struggling to get a good night's sleep, or perhaps need to get your head down at unusual times during the day, blackout blinds could be your saving grace. They help to prevent unnecessary disruptions to your sleep by blocking outside light pollution, whatever the time of day. It's worth getting blackout blinds that are made to measure, as this will make sure no excess light spills through to your bedroom."

And for noise? "Shutters are also a good option for the bedroom," says Lucy, "particularly if you're looking for a way to control the level of light that filters through. Not only that, shutters are great for privacy, and also add an extra wall of insulation to your windows, blocking out some of the sound coming from the outside so you can get the best night's sleep possible."
