It might seem difficult, but it's never too late to go back to school as a 40 year old in your underwear! We believe you in you! Even if you don't make it I'll bet you end up with some kind of certificate or cool title...
I take 30 minute naps on my lunch breaks all the time . Sometimes I wake up a little confused but it is refreshing. I also work from home so I'm sleeping in my own bed . Also having a newborn any extra sleep is appreciated.
Naps are not recommended by sleep psychologists if you are someone who has trouble falling asleep at night anyway, unless you are extremely fatigued, and in those cases, the earlier in the day the better so you can recharge your sleep drive before night.
But yeah, I too wish I could give myself an actual refresh during the day with a siesta, but alas no.
I am not a sleep psychologist and this isn't medical advice, second-hand info.
A buddy used to do that when we had practise. We'd meet at 6pm and he'd take a nap at like 4pm and then text us around 7 to 8pm, when we'd be finished already, that he napped lol
