I'm loving this nap bro.......but I have a doubt man ......I sleep around 4 to 5 hours at night a normal sleep without binaural and take a 30 minute power nap in afternoon . Is it okay for my health ? Or are there any long term side effects / disadvantages.

Would help me if u reply. Thanks bud btw
Depends on your age. Under 21 and less than 8h sleep a night = brain damage. Over 25, you can try polyphasic sleep but it requires consistent training. I have a series coming to explain this more ... but generally, I'd agree with Nicolas here!
