After the hectic pace of last few days, you get time to be still – BDN (busy doing nothing). It is an essential part of life as it gives your brain a time to refresh and rejuvenate. Just lying down and listening to your thoughts will make you realize the amount of information you are able to recall. And you may tell yourself to discard the information that is not relevant. If you are a yoga practitioner then, doing the upside down poses would be beneficial.
