This past summer brought the hottest July on record, and Americans were already running short on sleep before it arrived. New 2026 data shows a significant share of them are changing their approach to wellness, and they are heading toward less complexity. What they are choosing turns out to be the kind of habits that have been around a lot longer than the wellness industry has.
The sleep picture heading into summer was already uneven. In 2024, close to 3 in 10 American adults slept fewer than seven hours a night, and 45.2% did not report waking feeling well-rested most days or every day. More than a third of adults between 50 and 64 reported short sleep duration. Women were less likely than men to wake up feeling well-rested, with 51.7% of women reporting they woke rested most days compared with 58.2% of men. These were the numbers before summer arrived.
What the heat actually cost
A new analysis of 253 U.S. cities found that Americans lost an average of 36 hours of sleep per year to higher nighttime temperatures over the 2020 to 2025 period, about four and a half eight-hour nights annually. Of that total, roughly four hours per year, or about 13%, were attributable to human-caused climate change, with the remainder linked to nighttime heat more broadly.
The cities with the largest climate-change-linked sleep losses were in Arizona, California, Florida and Nevada, where losses ran between seven and nine hours per year. Heat-related sleep disruption is widespread across U.S. cities, with the largest climate-change-linked losses concentrated in cities in those four states.
Across those 253 U.S. cities, climate-change-related sleep loss has roughly tripled since the early 1970s, from just over one hour per year to about four hours per year. Sleep loss of that scale can affect mood, cognitive performance and productivity, according to the same analysis.
The urge to simplify
More than half of respondents in a 2026 survey of 2,000 U.S. adults said they planned to change their wellness routines this year. Among that group, 44% said they were focusing on foundational habits such as sleep, movement, hydration and nutrition, compared with 21% pursuing more advanced optimization strategies. That is more than twice the share choosing to optimize.
Podcasts, AI-powered apps, wearable devices and social media feeds have created what the survey describes as an unprecedented volume of health information and optimization tools, and Americans are split on how to feel about it. Half say they feel empowered by the available health information, while one-third say they feel overwhelmed.
Among younger adults, 70% of Gen Z say they feel pressure to keep up with the latest health and wellness trends. Around 53% report frequently experiencing health FOMO, defined as a fear of missing out on their wellness goals because they are not keeping up with the latest trends and tools.
What going back to basics actually means
Sleep, movement, hydration and nutrition are the foundational habits the 2026 survey identifies as the focus for Americans looking to change their approach. They share a practical quality; none requires specialized equipment, a subscription or significant prep time, which makes them easier to sustain if schedules tighten. Sleep is the habit the Climate Central data addresses most directly, which gives it particular relevance heading into fall.
When asked to grade their own health, only 20% of Americans gave themselves an A in the same survey, while 31% gave themselves a B and 37% a C. For the 68% sitting at a B or a C, foundational habits offer a practical starting point. They are low in complexity and low in cost, which matters when schedules tighten and enthusiasm is finite.
Smaller window, longer runway
New York loses roughly 77 minutes of daylight across September, and Chicago loses about 80, a pace that makes the season feel shorter than the calendar suggests. The final months of the year are now in view. The real question September raises is whether what gets started now is sustainable enough to still be running by December.
Sleep, movement, hydration and nutrition share one quality that most optimization strategies do not. They are measurable, repeatable and do not require upgrading. September is also one of the few moments in the calendar when the gap between wanting to feel better and actually acting on it is narrow enough to step across.
