The Sleep Problem: More than 1 in 3 people suffer from poor sleep

The Sleep Problem: More than 1 in 3 people suffer from poor sleep

Poor sleep affects your physical and mental wellbeing, your energy, resilience, your ability to think clearly and function effectively at home or work, and it can increase your risk of obesity, heart disease and diabetes. 

We understand sleeping problems - our survey of 1,503 people highlights the scale of the sleep issues. Our research shows more than 1 in 3 of us (37%) have sleep issues, saying we often struggle to sleep or are insomniacs. Just 1 in 5 of us say we have no problems sleeping. 

At DR.VEGAN® we’re passionate about simplifying nutrition, helping you understand your diet and lifestyle to make healthier choices. Our range of vegan supplements cater for all diets and range of health goals, including vitamins for sleep.  

Here are the key headlines from our research. 

Exercise and sleep

We all know exercise is important for our general health and wellbeing, and research shows it's just as important for sleep. 

People who do no exercise each week are significantly more likely to suffer from poor sleep compared to those who exercise 2-5 hours a week or more. 

Exercise isn't always a cure for a good nights sleep - our research shows more than 30% of us suffer from poor sleep even when we do more than 5 hours of exercise a week. 

What it does show however is poor sleep is much more common among those who do no exercise.  

Diet and sleep

Our research shows poor sleep is less common among people who have adjusted their diet from a general 'eat everything' or omnivore diet.

We defined an 'Adjusted Diet' as anyone who said they follow a flexitarian (plant-based with occasional inclusion of meat), pescatarian (plant-based and fish, but not meat), vegetarian or vegan diet.  You may enjoy our article 'Mistakes to avoid on a plant-based diet'.

Again, however, our research shows that changes to diet on its own doesn't solve the sleep problem. 

Sleep and stress

More than 4 in 10 people in our survey describe their stress levels as high or overwhelming, and only 1 in 10 describe themselves as stress free.  These are staggering statistics.  Our research shows poor sleep is twice as common among people with high levels of stress than those who describe their stress as manageable.


High levels of anxiety or stress raise your cortisol levels - cortisol is your stress hormone, and is a natural hormone that drives our 'fight or flight' response to danger.  However cortisol inhibits melatonin, our sleep hormone, which is why those with higher levels of cortisol in the evenings are more likely to suffer sleep problems.  Learn more in our article "What is cortisol?"

While it's easier said than done, managing our stress really does help improve our sleep, and vice versa.  Ashwagandha helps lower cortisol and is commonly taken in the evenings by those who suffer poor sleep, helping lower cortisol and allowing the body to product melatonin. Discover our Ashwagandha KSM-66 for lowering cortisol and relieving stress and anxiety.  You may also enjoy our blog: 5 foods to improve your mood.

Age and sleep

Poor sleep consistently affects 3 in 10 of us between the age of 18 and 44.  However, once we reach 45, poor sleep affects more than 4 in 10 of us. 

Changes in our hormones as we age, particularly among women during the menopause, lifestyle and family demands contribute to a likelihood of suffering poor sleep. 


There is no single winning ingredient to a great night's sleep, or conversely it is unlikely just one thing will cause regular poor sleep. 

However the research shows common factors among those who don't experience any problems with poor sleep:

  • 8 out of 10 do at least 1-2 hours of exercise each week. 
  • 7 out of 10 describe their stress levels as manageable or better. 
  • 6 out of 10 are on a flexitarian, pescatarian, vegetarian or vegan diet.
