Article Summaries:
- A Harvard‑led clinical trial, led by Brigham and Women’s Hospital and discussed by Lusomé founder Lara Smith, examined whether a sleep surface that promotes cooling can improve real‑world sleep. Sixty‑four participants recorded nearly 2,700 nights of data, with a two‑week baseline and a four‑week post‑intervention period. The study found an average gain of 26 minutes of sleep per night, a clinically meaningful improvement that can accumulate to hours over time. Smith emphasizes that body cooling is essential for sleep onset and quality, noting that overheating-especially in perimenopausal women-can trigger night sweats and disrupt restorative sleep.
