#heat stress

A sunlit outdoor running track in late afternoon, shot from a low angle with shallow depth of field. In the foreground, a matte black bottle with a minimal off-white label sits on the edge of a warm terracotta-colored track lane, beside a folded white towel and a small glass of amber liquid catching golden light. Condensation beads on the bottle. A faint heat shimmer rises from the track surface and softens the background.

In the midground, slightly out of focus, a lean athlete in a sage-green tank top and charcoal shorts runs on a treadmill-like stretch of track, a thin sheen of sweat on their shoulders, their expression focused and calm. Their motion is gently blurred, suggesting endurance and rhythm. Long soft shadows stretch across the lane lines.

The background fades into hazy peach, apricot, and pale yellow tones, with the suggestion of tall trees and a distant stadium wall. Warm sun flare enters from the upper right, creating a subtle glow and a few soft light streaks across the frame.

Subtle editorial touches: a small notebook with a pencil and a stopwatch rest beside the bottle, hinting at data and timing without any text legible. The color palette is warm and muted, with terracotta, cream, sage, and charcoal accents, and a fine film-like grain. The composition leaves open negative space on the left third for a headline overlay. The overall mood is clean, modern, and health-journal inspired, natural and aspirational, with a calm scientific curiosity rather than hype.

Ketonska pića na vrućini: duži izdržaj i oštrije pamćenje?

Ketonska pića su popularna među biohakerima kao sredstvo za sagorevanje masti, ali najnovije istraživanje pod toplinskim stresom pokazuje da mogu i da poboljšaju izdržljivost i rad radne memorije. Kod 17 sportista kombinacija ketonskog monoestra i kofeina produžila je vreme do iscrpljenosti na 8,9 minuta naspram 7,0 minuta uz ugljene hidrate i kofein, a tačnost na zadatku 1‑back je porasla. Niti otkucaji srca niti telesna temperatura nisu se značajno promenili. Studija je mala, isključivo muška i jednosesijska, pa je važno znati šta podaci zaista znače.
