How much time outside is enough? It is one of the most common questions parents ask — and one that has a clear, evidence-based answer in the UK. The Chief Medical Officers (CMOs) of England, Scotland, Wales and Northern Ireland publish joint physical activity guidelines that set out exactly how much active play children need at each age, from birth through to 18. These are not general suggestions: they are official public health recommendations, endorsed by all four UK governments and grounded in a substantial international evidence base.
This article explains what those guidelines say, breaks them down by age, explains the difference between light and vigorous activity, and offers practical guidance for how parents can help children meet the recommendations through everyday outdoor play. TP Toys is a UK-based manufacturer and specialist in outdoor play equipment, including trampolines, climbing frames and garden play systems, and has produced this guide as part of its commitment to supporting active, healthy childhoods across the UK.
How much outdoor play do children need each day in the UK?
According to the UK Chief Medical Officers' Physical Activity Guidelines (2019), children aged 1–4 need at least 180 minutes — three hours — of physical activity spread across the day, including active and outdoor play, with pre-schoolers aged 3–4 requiring at least 60 of those minutes at moderate-to-vigorous intensity. Children aged 5–18 need an average of at least 60 minutes of moderate-to-vigorous physical activity per day across the week. Outdoor play is one of the most effective and natural ways for children of all ages to meet these guidelines.
What are the UK physical activity guidelines for children at each age?
The UK CMO guidelines cover all age groups from birth to 18 and are the definitive reference point for physical activity recommendations in the UK. They were most recently updated in 2019 and apply across all four nations — England, Scotland, Wales and Northern Ireland. The table below summarises the key recommendations for each age group.

A key principle running through all the guidelines is that more activity is always better, and that any activity is better than none. The figures above are minimums, not targets — children who comfortably exceed them gain proportionally greater health and developmental benefits. The guidelines also emphasise that activity should be spread throughout the day, rather than concentrated in a single block.
What do the guidelines say specifically about physical activity for children under 5?
The under-5 guidelines were developed for the first time as a standalone section in the 2019 CMO report, reflecting the growing evidence base for the importance of physical activity in early childhood. They are more detailed than the guidelines for older children because the developmental context is more specific.
Infants (under 1 year)
Babies should be physically active several times each day in a variety of ways. For infants who are not yet mobile, this includes at least 30 minutes of tummy time spread throughout the day while awake — a position that develops the neck, back and shoulder strength needed for later movement milestones. Any movement counts, including reaching, grasping, pushing and pulling.
Toddlers (1–2 years)
Toddlers should accumulate at least 180 minutes of physical activity at any intensity, including active and outdoor play, spread throughout the day. The guidelines are explicit that more is better, and that activity does not need to be structured or planned — active play, outdoor exploration, and movement-rich daily routines all count. The 180-minute minimum equates to three hours, which sounds substantial but is typically met naturally by an active toddler with regular outdoor access.
Pre-schoolers (3–4 years)
Pre-schoolers have the same 180-minute daily minimum as toddlers, but with an additional intensity requirement: at least 60 of those 180 minutes must be at moderate-to-vigorous intensity. This means genuinely energetic activity — running, climbing, jumping, chasing, bouncing — not just gentle movement. For most pre-schoolers, outdoor play is the primary route to achieving both the total volume and the intensity requirement, because indoor activities rarely produce the same level of sustained vigorous movement.
Garden climbing frames are one of the most effective ways for pre-schoolers to meet the moderate-to-vigorous intensity requirement at home. The TP Toys range of toddler and early years climbing frames suitable from 18 months — provides structured physical challenge across the key developmental areas: climbing, balance, grip and coordination. A pre-schooler who spends 20–30 minutes on a climbing frame as part of their daily outdoor play will typically exceed the vigorous-intensity requirement for that session.
What do the guidelines say about physical activity for children aged 5 to 18?
From age 5, the CMO guidelines shift to a single recommendation: at least 60 minutes of moderate-to-vigorous physical activity per day, on average across the week. Unlike the under-5 guidelines, this is expressed as an average — meaning a child who is very active at weekends and less active on school days can still meet the guideline, provided the weekly average holds.
The guidelines also specify that children aged 5–18 should engage in a variety of types and intensities of physical activity across the week, to develop movement skills, muscular fitness and bone strength — not just cardiovascular fitness. This means the 60 minutes should not always be the same type of activity. A mix of running, climbing, jumping and active play covers the full range of physical development needs more effectively than a single repeated activity.
Bouncing on a trampoline is one of the most efficient ways for children aged 5 and above to accumulate vigorous-intensity physical activity in a garden setting. The TP Toys trampoline range includes models suitable from toddler age through to teenagers, with weight limits and bounce surfaces scaled to different ages and sizes. Research examining trampolining as exercise in children consistently classifies it as vigorous-intensity activity — meaning 20–30 minutes of bouncing counts substantially toward the 60-minute daily guideline, while also providing bone-strengthening impact-loading and vestibular development that running alone does not.
What is the difference between light, moderate and vigorous physical activity for children?
The CMO guidelines distinguish between activity intensities because the health and developmental benefits differ. Both the total volume of activity and the intensity of at least some of it matter for children's health. Understanding the difference helps parents assess whether their child's outdoor play is meeting the right thresholds — not just in duration but in effort level.
|
Intensity level |
What it feels like |
Outdoor play examples |
|
Light |
Movement with minimal increase in breathing or heart rate |
Gentle walking, sand and water play, digging, slow cycling |
|
Moderate |
Noticeably increased breathing; can still hold a conversation |
Brisk walking, active playground games, cycling, swimming |
|
Vigorous |
Heavy breathing; difficult to speak in full sentences |
Running, chasing, climbing, bouncing on a trampoline, competitive sport |
For practical purposes, the simplest indicator of moderate-to-vigorous intensity is breathing and warmth: if a child is noticeably out of breath and warm during play, they are likely working at moderate intensity or above. For younger children, sustained running, active climbing and bouncing reliably produce this level of effort. For older children and teenagers, the activity needs to be more deliberately vigorous to produce the same physiological response as fitness improves.

Practical tip: The CMO guidelines specify that muscle and bone strengthening activities should also feature across the week for children aged 5–18. Climbing — which requires children to bear and move their own body weight — is an excellent combined cardiovascular and muscle-strengthening activity. A climbing session in the garden contributes to both the 60-minute aerobic guideline and the weekly bone and muscle strengthening requirement simultaneously. |
Are children in the UK currently meeting the physical activity guidelines?
The evidence suggests that a significant proportion of UK children are not meeting the CMO guidelines, particularly the moderate-to-vigorous intensity thresholds. This is a public health concern that successive governments and health bodies have acknowledged, and it is part of the reason the CMOs chose to make outdoor play an explicit component of their guidelines rather than leaving it implied.

The factors most commonly associated with children falling short of the guidelines are: reduced outdoor time, increased screen time, fewer opportunities for active travel (walking or cycling to school), over-scheduled daily routines that leave little time for unstructured play, and — particularly in the UK — weather and daylight limitations during autumn and winter months.
Access to garden play equipment is one of the most consistent predictors of whether children meet daily activity targets at home, because it provides a low-barrier, weather-tolerant outdoor activity option that does not require organisation, travel or supervision of the same intensity as sport or formal activity.
How can parents help children meet the daily outdoor play guidelines?
Meeting the CMO guidelines does not require structured exercise programmes or expensive equipment. For most children, the guidelines can be met through a combination of everyday active play, active travel, and — where available — outdoor play equipment that provides sustained physical activity across the day.
Practical strategies for meeting the guidelines by age
· Under 5s: prioritise regular outdoor sessions across the day rather than a single long one — three sessions of 60 minutes each are more effective than one 180-minute block, because activity sustained across the day produces better developmental outcomes than activity concentrated in one period. In practice, 180 minutes is more achievable than it sounds: a 45-minute outdoor play session after breakfast, 45 minutes at a park or garden in the afternoon, and 30 minutes of active outdoor play before dinner gets a toddler to 120 minutes without any formal exercise at all. The remaining time accumulates naturally through active travel, garden pottering and physical movement around the home. For families with garden play equipment — a climbing frame, a toddler trampoline or a mud kitchen — the outdoor sessions are likely to be longer and more active than those without, making the guideline significantly more achievable.
· 5–11 years: combine active outdoor play with active travel where possible — walking or cycling to school can contribute 20–30 minutes of moderate activity before the school day begins, making the 60-minute target significantly more achievable. A child who walks briskly to school (20 minutes), has active break and lunch times (15–20 minutes combined), and then spends 20–30 minutes in vigorous outdoor play after school has typically met or exceeded the daily guideline without any formal exercise programme. Garden play equipment that generates vigorous activity — a climbing frame, trampoline or swings — is particularly effective for after-school play because it sustains activity for longer than unequipped outdoor time.
· 12–18 years: activity levels drop sharply at adolescence, particularly for girls. Maintaining access to enjoyable physical activity — whether garden-based, sport-based or active social activities — is more effective than formal exercise prescription at this age
· Year-round: UK weather is a genuine barrier to outdoor play, particularly between October and March. Garden play equipment that remains usable in cold or wet weather — and clothing that makes outdoor play comfortable in those conditions — significantly extends the number of days per year children can meet their activity targets outdoors
Families looking to build a home environment that supports daily physical activity targets can explore the full TP Toys outdoor play range, which spans toddler-appropriate physical play through to equipment suited to teenagers. The most effective home setups for meeting CMO guidelines tend to include at least one piece of vigorous-intensity equipment — a trampoline or climbing frame — alongside space for running, active games and exploratory play. This combination covers the full intensity spectrum the guidelines require across a typical day.
What is the evidence base behind the UK physical activity guidelines for children?
The CMO guidelines are not arbitrary targets. They are grounded in a substantial international evidence base, developed through a systematic review process that examined the relationship between physical activity levels and a range of health and developmental outcomes across childhood and adolescence.
· Physical health: regular physical activity in childhood is associated with lower risk of obesity, better cardiovascular fitness, stronger bones and muscles, and healthier weight status — benefits that compound over time and persist into adult life
· Mental health: the CMO report notes that regular physical activity in children and young people is associated with improved mental health and wellbeing, including lower rates of anxiety and depression, better mood and higher self-esteem
· Cognitive development: the 2019 guidelines cite evidence that regular physical activity is associated with improved learning, concentration and academic attainment in children — a finding that has strengthened substantially since the previous 2011 guidelines
· Sedentary behaviour: the guidelines explicitly note that prolonged sedentary behaviour is harmful to children's health independently of physical activity levels — meaning that even children who meet the activity guidelines benefit from breaking up long periods of sitting or screen time with movement
· Developmental trajectory: the CMOs note that physical activity levels reach a lifetime peak around age 5 and decline steadily thereafter — making the early years the critical window for establishing active habits that persist into later childhood and adolescence
Frequently asked questions about outdoor play and UK activity guidelines
Do screen time limits form part of the UK CMO guidelines?
The UK CMO guidelines do not set specific screen time limits for children, which distinguishes them from the WHO guidelines (which do recommend limits for under-5s). However, the UK guidelines do emphasise minimising sedentary behaviour and breaking up long periods of inactivity — and screen-based activity is typically sedentary. The implicit message is that time spent on screens displaces time that could be spent in active play, and that reducing sedentary time creates more space for meeting activity targets.
Does walking to school count toward the 60-minute guideline?
Yes — active travel, including walking and cycling, counts toward both the daily activity guideline and the intensity requirement if it is brisk enough to produce a noticeable increase in breathing and heart rate. A 15–20 minute brisk walk to school at a pace that makes children warm and slightly out of breath contributes meaningfully to the moderate-intensity component of the 60-minute guideline. Combined with break and lunch time outdoor play, active travel to and from school can account for a significant proportion of the daily target.
Does gardening or gentle outdoor play count toward the guidelines?
Light-intensity outdoor activity — gentle walking, digging, sand play, slow cycling — contributes to children's overall activity volume and has health benefits, but does not count toward the moderate-to-vigorous intensity requirement. For under-5s, any movement counts toward the 180-minute total, so light outdoor activity is valuable. For children aged 5 and above, the 60-minute guideline specifically requires moderate-to-vigorous intensity, meaning that gentle outdoor activity should be supplemented by more energetic play to fully meet the recommendation.
How do the UK CMO guidelines compare to WHO recommendations?
The UK CMO guidelines and WHO physical activity guidelines for children are broadly aligned. The WHO recommends at least 60 minutes of moderate-to-vigorous physical activity daily for children aged 5–17, consistent with the UK CMO guidance. For under-5s, the WHO recommends at least 180 minutes of physical activity including at least 60 minutes of energetic play — also consistent with the UK guidelines. The key difference is that the WHO guidelines include specific screen time limits for under-5s (no screen time for under-2s; maximum one hour for ages 2–4), while the UK CMO guidelines focus on activity rather than screen time directly.
Is there a minimum amount of time children should spend outdoors specifically?
The CMO guidelines specify physical activity levels rather than outdoor time specifically — the guidelines can technically be met through indoor activity. However, the guidelines explicitly include active and outdoor play as the recommended vehicle for meeting under-5 targets, and research consistently shows that outdoor play produces more vigorous, more varied and more sustained physical activity than indoor equivalents. There is no UK guideline specifying a minimum number of hours outdoors per day, but the EYFS statutory framework requires daily outdoor access for all registered early years settings — reflecting the same evidence base that underpins the CMO guidelines.
