Lots of people like to take a nap during the day as it can help them to feel refreshed and alert. 

It’s suggested to keep naps short (cat nap/power nap) of up to 30 minutes to get the benefit of feeling refreshed and to not interfere with sleep. Anything longer can result in grogginess and a nap of 90 minutes or more is indicative of not getting enough sleep through the night. However, rather than rely on a long nap in the day to ‘catch up’ on sleep, it would be advantageous to forego the nap to build up sleep drive and an appetite for sleep.

Ultimately, the client needs to check in with how a nap is affecting their sleep. If they feel refreshed and happy after a quick nap, it gives them energy and more focus without affecting sleep then a nap to recharge is a great idea. However, if they fall into a deep sleep during their nap, wake up feeling disoriented and groggy, it makes them less sleepy before bedtime so pushing the time going to bed later and less hours slept, therefore needing this long nap… creating a cycle of poor sleep… then napping may not be the best way forward for your client.
