How to stay awake

There are ideals and then there’s real life. In truth, you will at times find yourself tired but still obligated to stay alert. Here’s how to stay awake and make those moments as painless as possible.

This brain hack works best if you opt for something cheery, with a beat that’s strong and fast but not exhausting (100 to 130 beats per minute). Music with heart-rate lowering tempos – think 60 beats per minute or less – can actually induce sleep, so consider yourself warned.
Tonight, make it a point to add these podcasts to your playlist.
