Why do naps feel better than sleep?
Why do naps feel better than sleep? Next, the reason why a brief nap feels best. It takes about 90 minutes for your body (and brain) to go through a complete sleep cycle. Sleep too little and you've barely grazed the surface of light sleep. Sleep too long and you're swimming up from the groggy depths of deep sleep.
Do naps burn fat?
Yes, napping burns calories but not in large amounts. Even then, the overall health benefits make it worthwhile.
Should I go back to sleep if I wake up tired?
“You wake up feeling kind of groggy, like you have a dull headache, maybe a bit of nausea, and lethargy—you just don't feel like doing anything.” Your best bet is to resist the urge to nod back off after you wake up. But if the lure of your bed is just too strong, you can make a slight compromise.
