A softly lit bedside table in a calm, modern bedroom at dusk, photographed in wide landscape format with shallow depth of field. In the foreground, a matte white shaker bottle sits beside a tall frosted glass of creamy, pale vanilla-colored protein shake, with a few condensation droplets catching warm light. Next to the glass rests a slim fitness band on a dark charcoal fabric strap, its small LED glowing a gentle green, lying casually on a light oak wooden surface. A small scoop of fine white protein powder rests on a ceramic dish nearby, with a light dusting of powder on the wood.

In the soft-focus background, a neatly made bed with oatmeal-colored linen bedding and a textured knit throw blanket. A sheer curtain filters the last peach and lavender light of evening from a large window. A small potted olive branch in a terracotta vase and a closed paperback book add a quiet editorial touch. A bedside lamp with a warm, cream-colored shade casts a golden glow across the scene and creates gentle highlights on the glass.

The palette is muted and harmonious: warm cream, soft sand, oatmeal beige, faint sage green accents, and touches of dusty lavender in the window light. The mood is peaceful, reassuring, and clean, like a contemporary wellness magazine or a trendy health journal feature. Lighting is natural and cinematic, with soft shadows and a subtle film-like grain. The composition follows the rule of thirds, with the shake and band on the left third and open negative space on the right for headline overlay. Minimalist, Scandinavian-inspired styling, high-end lifestyle photography, crisp details, and a tranquil, premium editorial feel.

잠자리 전 카제인, 수면을 방해하지 않는다… WHOOP 데이터가 증명

잠자기 전에 40 g 카제인 쉐이크를 마시면 수면을 방해할까? 21명의 NCAA Division I 여성 선수들을 대상으로 한 무작위 이중 맹검 교차 실험이 WHOOP 4.0 밴드로 수면을 추적한 결과, 총 수면 시간, 효율성, 안정시 심박수·HRV 모두에 차이가 없었습니다. 알파‑락토알부민과 탄수화물 섭취도 같은 결과를 보였으며, 흥미롭게도 어느 조건도 수면을 개선시키지는 못했습니다.
