Physical activity & sedentary living

How much the world actually moves — and what it costs when we don't.

31%

of adults worldwide do not meet recommended physical activity levels

Roughly 1.8 billion adults were insufficiently active in 2022, up from 26% in 2010 — a rising trend across most regions.

World Health Organization, 2024

150 min

of moderate aerobic activity per week is the adult minimum

WHO guidance recommends 150–300 minutes of moderate, or 75–150 minutes of vigorous, aerobic activity weekly plus 2 days of strength work.

World Health Organization, 2020

81%

of adolescents aged 11–17 are insufficiently physically active

Inactivity is highest in adolescence and stays high into early adulthood, making school-age habits a major long-term risk factor.

World Health Organization, 2024

Nutrition & diet quality

Where global diets fall short of the simplest public-health targets.

400 g

of fruit and vegetables per day is the recommended intake

That is roughly five 80 g portions daily, excluding starchy roots such as potatoes and cassava.

World Health Organization, 2020

< 5 g

of salt per day — about one teaspoon — is the adult ceiling

Most populations consume roughly double this, and excess sodium is a leading driver of raised blood pressure.

World Health Organization, 2023

< 10%

of daily energy should come from free sugars

A further reduction to below 5% of total energy intake is suggested for additional health benefits.

World Health Organization, 2020

Chronic disease burden

The conditions that dominate mortality — and how preventable they are.

43M

deaths a year are caused by noncommunicable diseases

NCDs — cardiovascular disease, cancer, chronic respiratory disease and diabetes — account for roughly 75% of all non-pandemic deaths worldwide.

World Health Organization, 2024

1.28B

adults aged 30–79 live with hypertension

About 46% of them are unaware they have it, and only 1 in 5 have it under control.

World Health Organization, 2023

830M

people worldwide live with diabetes

More than half of adults with diabetes were not receiving medication for the condition in 2022.

World Health Organization, 2024

Sleep & mental wellbeing

Two areas readers underestimate most, with the clearest numeric targets.

1 in 8

people globally live with a mental disorder

Anxiety and depressive disorders are the most common, and both rose sharply following the COVID-19 pandemic.

World Health Organization, 2022

$1T

is lost to the global economy each year from depression and anxiety

Lost productivity from these two conditions alone, underlining prevention as an economic as well as clinical priority.

World Health Organization, 2024
