Life expectancy has almost fully recovered from COVID. Healthy years still lag behind
Estimates published by the World Health Organization on October 2 put global life expectancy at 73.3 years in 2023, almost its pre-pandemic level. Healthy life expectancy recovered more slowly. The difference matters, but it is not a personal forecast of the age at which we will become ill.

The world has moved close to its pre-COVID life expectancy again, but progress in the number of years lived has not been matched by an equivalent recovery in health. According to the World Health Organization's new estimates, life expectancy in 2023 was 73.3 years, compared with 73.4 in 2019. Healthy life expectancy reached 62.8 years, still 0.4 years below its pre-pandemic level.
This is a new publication about earlier years: the update was published in October 2026, but the data end in 2023. It does not measure the world's health this week, nor provide a personal forecast for an Israeli reader.
What is measured when healthy years are counted?
Life expectancy and healthy life expectancy answer two different questions. The first describes the years of life expected based on population mortality patterns. The second adds the loss of health over a lifetime due to diseases and injuries, and its severity, to the calculation.
The second measure is called HALE. According to the WHO definition, it expresses equivalent years of life in full health. Simply put, the calculation also considers situations in which a person lives in less than full health, not only whether they are alive.
This leads to an easily missed distinction: the 10.5-year gap between the numbers does not mean everyone will live healthily until 62.8 and then be ill for a decade. Health loss can occur at different times and levels of severity, sometimes alongside good daily functioning. The measure weights it at the population level.
Year of birth does not turn the number into a promise either. It is a calculation based on mortality and illness patterns during a given period, not a study following babies to the end of their lives or advance knowledge of the treatments and risks they will encounter.
Greater weight for noncommunicable diseases
The update points to a broad shift in the composition of mortality. Noncommunicable diseases accounted for 74% of deaths worldwide in 2023, compared with 58% in 2000. Eight of the ten leading causes of death belonged to this group.
Cardiovascular diseases remained the leading cause of death and disease burden. Alzheimer's disease and other dementias rose from 19th among causes of death in 2000 to fifth in 2023. These are population data; the ranking change should not be read as though every individual's risk increased by the same proportion.
Why a global estimate is not an Israeli answer
The Global Health Estimates database combines different sources, including national death records, estimates from health programs, UN agency data, and scientific studies. Processing allows comparisons across periods and places, but the result is a statistical estimate, not a complete, uniform count of every disease in every country.
The database allows examination by country, age, and sex. A comparison with Israel therefore requires the appropriate data and the same indicator definition. The global average alone does not tell us how many healthy years Israelis can expect, or establish the situation of a particular age group in Israel. Comparing two headlines published in different years can also mislead if they rely on different updates and methodologies.
The practical question begins before retirement age
Life expectancy data are not a treatment plan. They do, however, direct attention to prevention and disease management across the lifespan. WHO lists smoking, physical inactivity, an unhealthy diet, harmful alcohol use, and air pollution among risk factors for noncommunicable diseases. It also emphasizes early detection and timely treatment.
For the reader, this can become a focused conversation at the next medical visit: which personal risk factors need monitoring, whether blood pressure, blood sugar, and lipid measures have been checked as appropriate, and which habits or treatments should be adjusted. The answers depend on age, medical history, and individual circumstances, not one global number.

Responsibility is not solely personal either. Access to care, environmental conditions, and social circumstances affect health. Disease is not proof that someone has failed to manage their life. The measure offers health systems a broader goal: alongside extending life, reduce the health loss that accompanies it.
