Google plans to release a redesigned Fitbit app this fall that reorganizes the interface into three main tabs: "Today," "Coach," and "You." The refreshed app will display daily health statistics, offer motivational and coaching content, and present goal overviews and trends. Google says the update will improve how fitness data is presented and protected, and it appears visually aligned with leaked looks of the upcoming Pixel Watch 2 and possibly the Pixel 8 phones.

Researchers presented new findings at the European Society of Cardiology meeting showing that laughter therapy can improve some measures of heart health in people with coronary artery disease. In the study, patients took part in guided laughter sessions while researchers measured inflammation markers and cardiovascular performance before and after. The reported results included lower inflammation and improved indicators of heart function after the laughter interventions.

Researchers reviewing clinical trials have found little evidence that blue‑light filtering glasses provide the sleep or short‑term eye‑comfort benefits often claimed by makers and some retailers. The review pooled data from 17 randomized trials and reported no consistent short‑term reduction in visual fatigue from computer use, and it could not show clear benefits for sleep quality, vision performance, or long‑term retinal health.

Researchers at King’s College London have reported links between irregular sleep patterns and changes in the gut microbiome. The study focused on “social jet lag,” where people shift their sleep timing between workdays and free days.
