RISE appNASA astronauts needed sleep medication in space. The reason has nothing to do with comfort.🪐 RISE's @Dr. Daniella Marchetti breaks down what we learned from the Artemis crew's Vogue interview. In microgravity, your spine decompresses, pressure drops, and astronauts describe some of the deepest sleep they've ever had. But sixteen sunrises a day, constant artificial light, and no natural temperature drop meant their bodies had no way to know *when* to sleep. The takeaway for us on Earth: comfort and position matter less than your circadian cues. Getting morning sunlight and dimming your lights before bed tells your brain when to be alert and when to wind down. When that signal hits at roughly the same time each day, everything else about your sleep falls into place. 💫 RISE personalizes your light and wind-down timing so you get your best sleep here on Earth 🌎 #artemis #nasa #sleep
