Talk to the hand, sanitizer (Day 244)…

October 30, 2007


There’s a lot of debate about whether hand sanitizers are as effective as soap and water, and if they are, whether or not they kill off too much friendly bacteria so we’re left with cruddy immune systems. Some say we should do away with them altogether, others say it depends on the brand and how much alcohol is used, and of course the folks that make it can tell you 99 reasons why it’s absolutely necessary.

Personally, I think hand sanitizers have their place in certain situations: In hospitals, or other areas where people are especially prone to catching a disease; when travelling in less-than-spic-n-span environments; or when soap and/or water aren’t available.

However, in my current state of affairs — healthy, living in a first-world country with ready access to soap and water — I really don’t need hand sanitizer. Yes, there are some natural brands like CleanWell or EO, but it’s better to go without any of that packaging.

So as of today, I’m going to have a germ party on my hands and everyone’s invited! (And, um, Dr. Bronner gets VIP access.)

Maybe pools aren’t so cool (Day 220)…

October 6, 2007

From the ages of 16 to 20, I had the greatest job. I got to sit by a pool, work on my tan and occasionally yell at someone for running — yep, I was a lifeguard. Since then, however, I rarely go in public pools, having seen all the s— that goes in them: by the end of a hot summer’s day, there’d be so much sweat, suntan lotion, urine, hair, baby throw-up, diaper bits, etc. that we could barely see to the bottom. In order to “clean” all of this, we had to pump water out, filter more in and infuse it all with a whole bunch of chlorine and other chemicals.

As you can see from the diagram above, pools aren’t just a hole in the ground filled with water — they’re a complex system that requires a lot of energy, maintenance and often thousands of gallons of water, which in an outdoor pool can evaporate at least a few inches per day. The more people that use it, the more bacteria develops, which means all the more bleach to kill it off. When I was on swim team in high school, I actually had to stop wearing any silver jewellery because it would get tarnished after just a couple hours, and I had to use special swimming shampoo because, even with a bathing cap, my hair would still be completely wrecked.

So while pools can be a good alternative to blasting the air-conditioning in the summer, an even better option is the beach, a lake, or any natural source of water. From now on, then, I’ll be giving my local lifeguards one less body to worry about and swimming in water that won’t burn my eyeballs so much.
