A good friend, Mary Jones, posted this story on her blog on March 6, 2021:The benefits of an afternoon sleep, on The Accidental Ringer
Good news. Taking a nap in the afternoon can improve your memory and keep your brain more agile.
Researchers in China persuaded 2000 adults to endure an afternoon nap of between 5 minutes (that’s no nap – that is just resting your eye lids for a bit) and up to 2 hours. They discovered that even 5 minutes rest after lunch can help people to remember things and to speak more fluently afterwards. The nappers were also found to perform better in problem solving tasks and were more alert and aware of their surroundings. It appears that inflammatory chemicals are regulated by the act of napping, which in turn can prevent poor health. We are therefore advised to grab 40 winks during the afternoon, if we can, in order to allow our brains to “do some housekeeping”. The most beneficial types of nap are either no longer than 40 minutes (before someone enters the deepest stages of sleep) or for two hours (to allow a full sleep cycle).
I will take the full two hours please.
I am surprised that someone felt it necessary to do the research. I have been an habitual afternoon napper for most of my life. Give me a horizontal surface and a comfortable ambient temperature and I am asleep, especially if I have eaten a largish lunch. Actually, I don’t even require a horizontal surface. Just the largish lunch will do it for me. When my kids were small, friends knew not to pop round or phone between 1.30-3pm because the baby would be asleep. So would I. Both of us co-sharing a queen sized bed. Both of us boosting our brain power.
The same is still true today. Please do not phone between the hours of 1.30-3.30pm. I will often be resting my eye lids.
