How much sleep to your actually need? - gut health, sleep,

The big question is, “How much sleep is ideal?” Turns out that the magic number is 7️⃣.
“In fact, we found that people who slept that amount (seven hours) performed – on average – better on cognitive tests (including on processing speed, visual attention and memory) than those who slept less or more. Individuals also need seven hours of sleep consistently, without too much fluctuation in duration.”
