The Benefits of Cold Showers

The Art of Manliness explains why you should grab your shower cap, bite your lip, and jump into an ice-cold shower.

Enjoy!

People have been subjecting their bodies to extremely cold water for thousands of years, but is it really worth the torture? Among some of the possible benefits like helping with depression, increasing testosterone in men, and developing emotional resiliency, there are several more benefits to be had:

  • Improve circulation: Your heart has to get pumping to try and warm you up, and that helps increase cardiovascular health.
  • Improve sleep: Taking a cold shower one hour before bed may help your body trigger sleep signals and give you a deeper sleep.
  • Keep skin and hair healthy: Cold water can add shine to your hair and close up your pores.
  • Speed up workout recovery: Cold exposure decreases inflammation and helps remove toxins like lactic acid because blood flow increases as your body warms up. The same reason athletes take ice baths.
  • Give an energy boost: Cold water will give your body a jolt of energy like nothing else. If you don’t believe it, give it a try.

The Name Origins Of Alcoholic Drinks

John Green looks at the name origins of 26 alcoholic drinks including the Martini, Alabama Slammer, and the Sidecar.

You don’t need to be a professional bartender to know the difference between a sidecar and a Tom Collins, but if they’re not drinks you order regularly, you may not know how they’re made or what the history behind them is. This video from the folks at Mental Floss will teach you.P

The video tells the tale, but odds are that if you’re not an avid cocktail drinker you’ve heard of some of these drinks before but didn’t know how they were made, or what was in them. John Green’s approach to the topic is hilarious, but it’s also educational—by the end of the video you’ll be familiar with all sorts of different drinks, from mimosas to sidecars to the ever-classic martini. Plus, the next time you’re at a bar and want to order one, you’ll know what should go in it (and you’ll be able to tell if the bartender has no idea).
