What if sleep is the best cognitive exercise?

• thinkharderdev 4y ago
  Depends on the relevant margin. If you get adequate sleep then sleeping more won't help (and may actually hurt) but exercise can actually raise the baseline. To use a very rough analogy, sleep is like the fan in your computer. If it's working optimally it ensures you can utilize the CPU close to its physical limit. But exercise is like upgrading the CPU.

  Anecdotally, exercising regularly has improved my sleep quite a lot.
