There is perhaps no environment more immediately suited to LEDs than hospitals. It stands to reason that patients would rest better if bright lights didn’t keep them awake at night. And that they would simply feel better if poorly-lit wards and rooms didn’t induce a general fogginess. Better still if tunable lights mimicked the shifting pattern of sunlight for a strong daytime semblance. To take all of that to a logical conclusion: Patients who rest and feel better surely must recover faster.
