# Stanford study: Older adults face heat risk at lower temperatures than estimated

*Research finds 22% of people over 60 will face unsafe heat for at least a month yearly if warming reaches 1.5°C*

**Scores for the source reporting** (0-100, assessing the original journalism this article was written from, not this write-up): 

- Trust 85 of 100, higher is better. Two full reports and 24 digests agree on core findings and figures.
- Craft 85 of 100, higher is better. All affected groups quoted or given context; clear separation of fact and comment.
- Hype 15 of 100, lower is better. Headlines match the measured tone of the body text.

**The short version**

- A Stanford University study found older adults face dangerous heat at temperatures 4.7 to 7.5°C lower than younger people can tolerate.
- If global warming reaches 1.5°C, 22% of people over 60, about 290 million, will be exposed to unsafe heat for at least a month each year.
- Each additional degree of warming will expose roughly another billion people to an extra month of intolerable heat, with the greatest risks in India, Pakistan and Bangladesh.
- Most heat-related deaths occur indoors, increasing the need for cooling access in vulnerable regions.

A study led by Stanford University researchers found that older adults are far more vulnerable to heat than previously estimated. The research, published in *The Lancet Planetary Health* on 18 August 2026, used new data from wet-bulb experiments conducted on people over 60 in the U.S. to model heat tolerance across age groups.

Previous studies relied on heat thresholds for young, healthy adults, which the Stanford team said underestimated risks for older people. The new modelling showed that at 1.5°C of warming above pre-industrial levels, 22% of people over 60, about 290 million, would face unsafe heat for at least a month each year. Young adults would not reach similar risk levels until warming reaches 4°C.

The study warned that uncompensable heat, where the body cannot cool itself, would become more frequent and widespread. Regions with high poverty and limited cooling access, including India, Pakistan, Bangladesh, Myanmar and Niger, face the greatest threats. The researchers also noted that most heat-related deaths occur indoors, making access to air-conditioning and cooling facilities critical.

## What the coverage left out

None of the right-rated digests mentioned the study’s finding that most heat-related deaths occur indoors. The centre-rated digests largely omitted the study’s call for age-specific heat action plans, which was highlighted in ABC Australia’s full report. The left-rated digests did not include the study’s projection that at 3°C warming, elderly people in south Asia could face dangerous heat day and night for three months a year.

## Who covered it

Shares of the 19 covering outlets with a published leaning rating:

- Left: 29% (5)
- Centre: 47% (8)
- Right: 24% (6)

15 of 34 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-08-18T18:30:07.254363+00:00.

## How the sides framed it

### Left

- The five left-rated digests led on the study’s finding that older adults face heat risks at much lower temperatures than previously thought. ABC Australia’s full report quoted lead author Qinqin Kong stating that older people’s heat tolerance was 4.7 to 7.5°C lower than young adults’, and that 22% of those over 60 would face unsafe heat at 1.5°C warming. The report also highlighted concerns for Australia’s hotter regions, such as the Top End and Kimberley.
- Liberation’s digest emphasised the term “incompensable heat” and the 22% figure, while El Pais’s digest quoted the study’s warning that “many more people will be at risk.” The Indian Express’s digest focused on India, noting that older adults in Delhi and the Indo-Gangetic plain could face over 2,000 hours of intolerable heat annually at 3°C warming.

### Centre

- The eight centre-rated digests consistently led on the study’s finding that heat risks for older adults had been “dramatically underestimated.” CTV News’s full report quoted the study’s conclusion that intolerable heat would affect “far more people than previously estimated” and noted that at 3°C warming, elderly people in south Asia and the Gulf could face dangerous heat day and night for three months a year.
- Le Télégramme’s digest highlighted the 22% figure, while Sud Ouest’s digest noted that humidity had been underestimated as a factor for older adults. The Japan Times’s digest pointed out that earlier research did not account for older people sweating less or having weaker hearts. Most centre-rated digests included the study’s warning about climate migration driven by uncompensable heat.

### Right

- The two right-rated digests, from the Bangkok Post and Free Malaysia Today, led on the study’s finding that heat risks for older adults had been underestimated. Both included the 22% figure for people over 60 facing unsafe heat at 1.5°C warming. Neither digest mentioned the study’s warnings about climate migration or the specific vulnerabilities of regions like south Asia.

## Questions

**How much lower is heat tolerance for older adults compared to younger people?**

The Stanford study found that people over 60 can no longer maintain a stable core temperature at temperatures 4.7 to 7.5°C lower than young adults. This means older adults face dangerous heat stress at much lower thresholds than previously estimated.

**How many older adults will face unsafe heat if warming reaches 1.5°C?**

The study estimated that 22% of people over 60, about 290 million, will be exposed to unsafe heat for at least a month each year if global warming reaches 1.5°C above pre-industrial levels. This risk increases with each additional degree of warming.

**Which regions face the greatest heat risks for older adults?**

The study identified India, Pakistan, Bangladesh, Myanmar and Niger as the countries facing the greatest threats. These regions have high poverty levels and limited access to cooling, making older adults particularly vulnerable to uncompensable heat.
