thoughts on sleeping 8 hours

Sources:

The concept of an 8-hour sleep is person-specific, and there's no general evidence suggesting that 8 hours is better than 6. Sleep needs may vary depending on multiple factors, including age, health, and personal lifestyle. Dr. has mentioned on the that while he personally enjoys an 8-hour sleep, he functions well with about 6 hours.

The importance of a regular sleep schedule and the quality of sleep also comes up as crucial components for maintaining overall well-being. Consistent habits and sleeping within 90-minute ultradian cycles can positively impact performance and cognitive function. Waking up at the end of an ultradian cycle, for example, after 6 rather than 7 hours may leave you feeling more refreshed.

Ultimately, finding the right amount of sleep that makes you feel rested and cognitively sharp is what's important, and this can involve trial and error to determine what works best individually.

Are there common myths about sleep?

Sources:

There are indeed several common myths about sleep, which have been addressed by Dr. and .

Here are a few debunked myths and misconceptions about sleep:

  1. The Myth of "Counting Sheep": Contrary to popular belief, counting sheep may actually make it harder to fall asleep, as found by a study at UC Berkeley.

  2. Smelling in Dreams: It is a myth that we cannot smell in our dreams. We are capable of smelling things in our sleep, although our ability to wake up in response to odors is diminished during REM sleep.

  3. Sleep as a Binary Switch: Sleep isn't a binary process like turning off a light switch; it's more gradual, like landing a plane.

  4. Oversleeping: As far as oversleeping is concerned, it is debated whether one can sleep too much, with some suggesting that overly long sleep could hint at an underlying health issue affecting sleep efficiency.

  5. Magnesium Supplements: There's a myth that taking magnesium supplements will improve sleep for everyone. However, data on magnesium supplementation for healthy sleepers is not compelling, except perhaps for certain populations with deficiencies or insomnia.

Each individual's sleep needs are unique, and suggestions and practices should be personalized based on one's health and lifestyle.
