The less your back is staying tensed against chill air, the more physically relaxed you can be. I have a Thinsulate-filled sleeping bag that I use like a throw for this as it reflects body heat better than a comforter. Sleeping on a sofa, up against the back cushions, and noticing how it was good for naps, was what alerted me to this one.</text><parent_chain><item><author>jisaacks</author><text>&amp;gt; I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes&lt;p&gt;Any advice on how you were able to achieve this ability?

Only in special situations, when you are under high pressure and lots of work, take &amp;quot;coffee nap&amp;quot; as they call it in the article.</text></item></parent_chain></comment><story><title>Coffee naps are better than coffee or naps alone</title><url>http://www.vox.com/2014/8/28/6074177/coffee-naps-caffeine-science</url></story>

Likely you try and take a nap a few times, it takes too long and so the next day you don&amp;#x27;t bother. But if you can get through that it gets easier over time. Your body learns that it&amp;#x27;s &amp;quot;time to go to sleep&amp;quot;.&lt;p&gt;The other strategy is physical and mental exhaustion, for this I recommend starting a business and&amp;#x2F;or becoming a parent.</text><parent_chain><item><author>jisaacks</author><text>&amp;gt; I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes&lt;p&gt;Any advice on how you were able to achieve this ability?
