If you\u2019ve felt like summers keep hitting differently, the data backs you up. A study published June 22, 2026, in Nature Climate Change<\/em><\/a> found that 1 billion more people now face at least one day of extreme heat stress every year than in the 1970s. And it\u2019s not just hotter days driving the trend.<\/p>\n

Lead researcher Rebecca Emerton<\/strong> of the European Centre for Medium-Range Weather Forecasts found that the 10 warmest nights of the year are heating up roughly 0.58 degrees Fahrenheit per decade on average. This means your body gets fewer hours overnight to recover before the next round of heat hits.<\/p>\n

Global heat-related deaths have climbed alongside it, rising from about 335,000 per year in the 1990s to 546,000 annually between 2012 and 2021, according to the 2025 Lancet Countdown report<\/a>.<\/p>\n

New research on sauna therapy and longevity<\/a> draws a sharp distinction between intentional, controlled heat exposure and the kind of uncontrolled overheating that builds up across a hot day and a warm night. Understanding that difference starts with knowing what heat stress actually does to the body and who\u2019s most at risk when it happens.<\/p>\n

Who Is Most Vulnerable to Heat Stress?<\/strong><\/h2>\n

Heat stress isn\u2019t an equal-opportunity condition. The World Health Organization<\/a> warns it can worsen cardiovascular disease, diabetes, asthma and mental health conditions while raising the risk of accidents and certain infections. Heat-related mortality in adults over 65 climbed roughly 85 percent between 2000-2004 and 2017-2021.<\/p>\n

Certain medications also raise your risk in ways most people don\u2019t realize. Diuretics, beta-blockers and antihistamines can all interfere with how your body regulates temperature, making it harder to cool down naturally. Pregnant women, people with obesity and people with lower cardiovascular fitness are also in the groups clinicians flag most often.<\/p>\n

\n\t\t\tSaunas are showing up everywhere lately, from gym recovery suites to infrared blankets marketed as longevity tools. The science behind them is more substantial than most wellness trends, but also more specific about what actually works. Here\u2019s what researchers have found. Can Sauna Use Actually Help You Live Longer? The evidence is genuinely strong, though [\u2026]\t\t<\/p>\n<\/div>\n

How Heat Makes Chronic Conditions Worse<\/strong><\/h2>\n

For anyone managing a chronic illness, a heat wave can go from uncomfortable to dangerous quickly. Here are the conditions where the research shows the clearest connection:<\/p>\n
