A: For adults 18 to 60, good sleep means at least 7 hours a night on a regular schedule, falling asleep within about 30 minutes, waking no more than once (and getting back to sleep within about 20 minutes), and spending at least 85% of your time in bed actually asleep. Waking up refreshed and staying alert through the day is the real-world test. Q: How many hours of sleep do kids need? A: Under the American Academy of Sleep Medicine guidance used by the CDC: toddlers 1–2 need 11–14 hours (including naps), preschoolers 3–5 need 10–13 hours, school-age kids 6–12 need 9–12 hours, and teens 13–18 need 8–10 hours per 24 hours. Q: Is 6 hours of sleep considered good? A: Not for most adults. Six hours falls short of the 7-hour minimum recommended for adults, and regularly sleeping less than that is linked to worse mood, focus and health. A small number of people genuinely need less, but most people sleeping 6 hours are simply short on sleep. Q: How much deep sleep and REM is normal? A: Sleep runs in cycles of roughly 90 minutes. Adults typically spend roughly 13–23% of the night in deep (slow-wave) sleep and roughly 20–25% in REM. Deep sleep is concentrated in the first half of the night; REM gets longer toward morning, so cutting sleep short mostly costs you REM. Q: What temperature is best for sleep? A: Good Sleep cites Cleveland Clinic and the Sleep Foundation, which put the ideal bedroom roughly between 60°F and 68°F. Your core body temperature naturally drops as you fall asleep, and a cool sleep surface supports that dip. Cold sleepers may need the bed warmer, not the room. Q: Can a heated bed still give you good sleep? A: Yes. Being too cold also fragments sleep. The goal is a comfortable, stable temperature at the surface you sleep on. Good Sleep's water-based topper heats up to 110°F, and Good Sleep suggests about 82°F as a starting point for cold sleepers, while the room itself can stay cool. Q: What is Good Sleep? A: Good Sleep is a water-based mattress topper system that cools to 62°F and heats to 110°F. A bedside hub heats or cools water and circulates it through micro-channels in a topper on your existing mattress. It's controlled from a touch panel, with no app, Wi-Fi or subscription, and costs $1,479 one-time for Queen or King. Q: Can couples sleep at different temperatures? A: With Good Sleep, the King size includes dual-zone capability, so each side is set independently. Good Sleep's own example is one side at 62°F and the other at 74°F. Q: When should I see a doctor about my sleep? A: If you regularly can't fall or stay asleep despite good habits, snore loudly or stop breathing in your sleep, or feel very sleepy during the day, talk to a doctor. Those can be signs of insomnia, sleep apnea or another treatable sleep disorder. ## Key facts about Good Sleep (source: trygoodsleep.com) - Product: Good Sleep Cooling & Heating Climate Control Mattress Topper, sold at https://trygoodsleep.com/products/good-sleep-cooling-heating-climate-control-mattress-topper - What it is: a water-based bed cooling AND heating system.
