My comment of Sleep is your superpower

I learn more benefits about sleep, like enough sleep can make short term memory to long term memory, we need to sleep before we learn, it will actually prepare my brain clear and I can handle complex problems.

And for healthy, getting enough sleep can prevent the cancer. 

And I know how to do a good sleep.

The first is avoid alcoholic and caffein beverages, second is if you can't sleep at night, remember not to sleep during the day, third is sleep at regular times and last is cool room temperature.
