Welcome to
Sleep Vitality
If you’re a “poor sleeper,” always tired or drifting off whilst driving, we understand.
Do you feel like you haven’t slept at all?
Is your smart watch or Fitbit reporting poor sleep?
Do you snore?
You may have insomnia or you may have a medical condition called sleep apnoea – which has serious complications.
If you suspect you have sleep apnoea and are on the NHS waiting list to see a doctor, we’ll see you right away. If you’re not sure what the problem is and just want a good night’s sleep, we’re ready to help.
Talk to our experienced sleep consultants! It’s your path to a good night’s sleep.
Why is sleep important?
A good night’s sleep is essential to overall good health. Your body requires six to nine hours of restful sleep every night to restore the cells, neurons, arteries and organs to keep your health optimal.
Without this restorative process, your risk of disease increases – including heart disease, diabetes, high blood pressure, stroke and dementia.
A global sleep crisis
75% of the population face a sleep crisis at least once in their lifetime.
A billion people worldwide have sleep apnoea.
In the UK, at least 1 million people have undiagnosed sleep apnoea.
You may have insomnia or you may have a medical condition called sleep apnoea – which has serious complications.
If you suspect you have sleep apnoea and are on the NHS waiting list to see a doctor, we’ll see you right away. If you’re not sure what the problem is and just want a good night’s sleep, we’re ready to help.

Improve sleep and health
Could your snoring be serious?
Loud snoring is a red flag for sleep apnoea; this symptom indicates that the air passage is blocked, creating the vibration we know as snoring. Typically it’s the tongue and throat tissues that cause this blockage – and this leads to “apnoeas” or pauses in breathing.
These pauses in breathing are serious, as they may occur dozens or even hundreds of times in one night. This deprives your body of oxygen needed for normal functioning.
Untreated sleep apnoea can cause issues with blood pressure, diabetes control and increase the risk of heart disease and stroke.

Helping organisations sleep better
People who get sufficient sleep every night function better during the day.
Their performance is at a high level, and they don’t fight sleepiness and fatigue or lose concentration while at work, driving or in sports competitions.
Sleep is essential to high productivity and function in any aspect of life.
Sleep Vitality can help corporate organisations by optimising sleep for their employees.
We can organise sleep lectures, group workshops and individual one to one sessions for high-performing executives.

Sports and performance
Sleep optimisation plans tailored to serious athletes and teams.
Poor sleep is linked to poor sports performance, including reaction times and recovery from training sessions. It is associated with an increased risk of injuries.
We can offer our extensive experience in optimising elite athlete performance in both team and individual sports. This can be customised to suit needs but can include team sessions on leveraging sleep for performance, bespoke sleep plans for each athlete, plus help with analysing data from Fitbit, Ouraring, Apple Watch etc.

He was extremely helpful explaining the procedure, and sending back my results promptly, making the whole experience easy
