You love coffee — the ritual, the steam-swirled calm, the tiny miracle in a mug. This week we’re looking at what that sip means for your health, your caffeine choices, and the little joys that make coffee more than just a drink.
Drinking very hot coffee or tea linked to triple oesophageal cancer risk
A large study out of Oxford found that habitual consumption of very hot beverages — think steam-that-burns-your-tongue hot — is associated with about a threefold increase in oesophageal cancer risk. For the person who measures life by mug temperature, this is a meaningful nudge to let that cuppa cool a bit; it doesn’t banish coffee, but it reframes ritual temperature as an actionable health choice. Read the reporting here: study on very hot drinks and cancer to see how small temperature tweaks could change long-term risk.
Peanuts x Starbucks drop
Starbucks rolled out a limited-edition Peanuts collection inspired by It's the Great Pumpkin at select locations — a wink for collectors and an excuse to buy another seasonal cup sleeve: see the merch.
Coffee/tea tied to lower cognitive decline
A study linked regular coffee or tea drinkers with a reduced risk of cognitive decline as people age, suggesting your daily ritual might be doing quiet work for brain health: read the findings.
Graphene tech halves caffeine
Researchers demonstrated a graphene oxide membrane that removes about half the caffeine from brewed coffee while keeping flavor compounds — a peek at future low-caf options for people who love taste but want less buzz: how the membrane works.
Espresso vs. drip: caffeine surprise
A single shot of espresso typically has less total caffeine than an 8-ounce cup of drip coffee, but espresso is more concentrated — so it feels stronger. That’s why your double-shot latte jolts you faster even if it doesn’t always have more total caffeine than a large drip.
