How long you should spend sitting, sleeping, standing and exercising each day REVEALED by scientists

Stand up for yourself — at least a lot more than you probably are. 

For an Australian study suggests standing for at least five hours a day is vital for ‘optimal’ health.

Researchers believe they have discovered exactly how long we should spend sitting, sleeping, standing and exercising every day to have, and keep, a healthy heart. 

Experts have warned for years that being stationary for too much of the day raises the risk of numerous health problems including weight gain, type 2 diabetes, cancer and even an early grave. 

Now a team of researchers say we should aim to sit for just six hours a day, three hours less than the UK average.

An Australian study suggests standing for at least five hours a day is vital for ‘optimal’ health. Researchers believe they have discovered exactly how long we should spend sitting, sleeping, standing and exercising every day to have, and keep, a healthy heart 

Just over two hours per day should be spent on vigorous exercise, like working out in the gym or taking a brisk walk. 

Light exercise, such as doing household chores or making dinner, should account for another two. 

And when it comes to sleep, eight hours and twenty minutes of shut eye is key. 

But people will only experience the lasting benefits of these measures on heart health if they practice them regularly, the researchers said. 

Dr Christian Brakenridge, study author and expert in exercise physiology at Swinburne University of Technology, Melbourne, added: ‘For different health markers, from waist circumference to fasting glucose, there would be different levels for each behaviour. 

‘This breakdown encompasses a wide range of health markers and converges on the 24 hours associated with overall optimal health.’

He added: ‘Of course, moving as much as you can is always encouraged when so much of life requires us to be sitting in front of screens. 

‘Shorter sitting time and more time spent standing, undergoing physical activity and sleeping give great boosts to our cardiometabolic health.’

The academics analysed data from more than 2,300 volunteers, aged 60, on average. A quarter had type 2 diabetes. 

They tracked their activity for eight days using a small monitor worn on their thighs calculating the total amount of time each spent sitting, standing and sleeping. 

The team then compared health markers among the participants, including waist circumference and glucose and insulin levels. 

It’s totally unrealistic for the working week, says EMILY STEARN

How I wish I only had to sit for six hours a day. 

Instead, I’m often sat for around 10 hours or more during the working day. 

I like to stay as active as possible during the week, breaking my day up with a long walk and fresh air.

Come the evening I try to boost my activity levels by going for a run, hitting the gym or seeing friends. 

But I’m certainly not hitting the recommended sleep per day. If I’m lucky it’s seven, but realistically it’s more like six and a half. 

EMILY’S TYPICAL DAY  

12.5 HOURS SITTING 

2 HOURS STANDING

7 HOURS SLEEPING

1 HOUR MODERATE TO VIGOROUS PHYSICAL ACTIVITY 

1.5 HOUR LIGHT INTENSITY PHYSICAL ACTIVITY  

That’s not at all how my day goes, says STEPHEN MATTHEWS 

What I’d give to get eight hours and 20 minutes of sleep each night. 

If I’m being honest, I’d say I probably only get about six, taking myself to bed at about midnight and waking at 6am.

There’s also no chance I am exceeding anymore than two hours of physical activity each day.

After walking part of the way home, I’ll get in late in the evening and slump on the sofa.

STEPHEN’S TYPICAL DAY

14 HOURS SITTING

2 HOURS STANDING

6 HOURS SLEEPING

2 HOURS LIGHT-INTENSITY PHYSICAL ACTIVITY

Factors that could skew the results, smoking history, education and diet, were also accounted for. 

They found those with ‘optimal’ markers spent ‘substantially’ less time sitting, longer standing and ‘a substantially greater time being physically active’.

Those with type 2 diabetes and who had ‘optimal compositions on average’ also favoured greater levels of sleeping time.

Writing in the journal Diabetologia, the researchers added: ‘Sedentary behaviour is adversely associated with cardiometabolic health

‘Less time spent being sedentary and more time spent participating in physical activity is associated with improved plasma glucose, insulin sensitivity, insulin levels, fat percentage, and triacylglycerol and cholesterol levels.’ 

They acknowledged, however that the data was merely ‘a recommendation’ and people’s time use must be ‘realistic and balanced’.

There may issues in the data in differentiating exactly how long participants spent on each of the types of activity measured.

For example, standing was recorded as being very similar to engaging in light physical activity.

Dr Brakenridge added that what activities people favoured over others would naturally impact the results.   

‘Sleeping may be detrimental to health if it replaces exercise time, but beneficial if it replaces sedentary behavior. 

‘This is why we need integrated guidelines considering the full spectrum of human behaviour.’

He added: ‘People may advocate for more time exercising, though it’s not feasible to have 10 hours of exercise and zero hours of sedentary behaviour — the time use has to be realistic and balanced. 

‘It’s also important to acknowledge that this data is a recommendation for an able adult. We all have different considerations, and above all, movement should be fun.’

Their recommendations also leave 10 minutes free in a 24-hour day.  

While the researchers have calculated what adults should ideally aim for in terms of activity people are still likely to benefit even if they don’t reach these precise goals.

For example, undertaking moderate exercise for two hours a day is still good for you even if you don’t commit to working out for precisely two hours and 10 minutes. 

HOW MUCH EXERCISE YOU NEED

To stay healthy, adults aged 19 to 64 should try to be active daily and should do:

  • at least 150 minutes of moderate aerobic activity such as cycling or brisk walking every week and
  • strength exercises on 2 or more days a week that work all the major muscles (legs, hips, back, abdomen, chest, shoulders and arms)

Or:

  • 75 minutes of vigorous aerobic activity such as running or a game of singles tennis every week and
  • strength exercises on 2 or more days a week that work all the major muscles (legs, hips, back, abdomen, chest, shoulders and arms)

Or:

  • a mix of moderate and vigorous aerobic activity every week – for example, 2 x 30-minute runs plus 30 minutes of brisk walking equates to 150 minutes of moderate aerobic activity and
  • strength exercises on 2 or more days a week that work all the major muscles (legs, hips, back, abdomen, chest, shoulders and arms)

A good rule is that 1 minute of vigorous activity provides the same health benefits as 2 minutes of moderate activity.

One way to do your recommended 150 minutes of weekly physical activity is to do 30 minutes on 5 days every week.

All adults should also break up long periods of sitting with light activity.
