I lived in Madrid, Spain for a year and although it took some getting used to, I ended up loving that the city closed down for "siestas" or nap-time for a bit in the afternoon. You'd go home, have a good meal, rest for a bit and then be recharged!
If you're someone who takes a quick midday snooze, you should keep doing this! According to healthspiritbody.com, studies have shown that it's a normal and integral part of the circadian (sleep-wake cycle) rhythm. A short nap can improve awareness and productivity. You don't need too much though. Just a quick 15-20 minute nap can make a big difference. You can read more on the benefits of naps during the day from healthspiritbody.com here! Finally some concrete evidence we should be napping at work! :)
