Although he’s not 100% right he does have several points that should be addressed…like advertising to kids and the over manipulation of the foods we eat. Even though it has been shown that organic farming isn’t very practical in terms of feeding the planet as a whole, there’s still a fundamental problem with the way we produce food and distribute it. I just thought that this was way cool that this young kid feels so strongly about an issue that more people should care about.
Perspire Much?! Don’t Sweat It…

Sweating is a release of water and sodium from the body’s sweat glands in an attempt by the body to regulate your body temperature. Sweat is typically found on your head, feet, the palms of your hands, and under your arms. The purpose of sweat is to cool the body by sitting on the surface of the skin and removing heat from the body as the sweat evaporates. The amount you sweat is directly dependent on how many sweat glands you possess with the average person being born with about 4 million. Women, on average, have more sweat glands than men but men’s’ sweat glands are typically more active. For both sexes, sweat glands can be activated by nervousness, anger, embarrassment, fear and physical exertion.
Sweating is most effective when it forms a glistening coat atop the skin allowing for even evaporation across the surface of the body. When sweat gets to the point that is starts dripping, that’s the body struggling to effectively control its own temperature and becoming less effective at cooling itself down. Contrary to popular belief however, the rate of sweating you are undergoing isn’t necessarily an indicator of how hard you are working. Your rate of sweating merely signifies how effective your body is at cooling itself down. This process can have several determining factors including humidity, environmental temperature, clothing and physical fitness.
Sweating and exertion especially do not correlate if you are returning to exercise after a long period of inactivity. When initially returning to an active state, especially when cardio is involved, you can sweat rather easily due to the fact it takes time for your sweat glands to adapt to the activity. The longer and the more consistently you do cardio the more efficiently you will start to sweat and the less you will “drip” at each level of intensity of exercise.
Instead of using rate of sweat as an indicator of your intensity of exercise, you should try using a “Borg Scale” to gauge your intensity. Since fatigue is highly correlated with your heart rate, the Borg Scale of Perceived Exertion (RPE) gives a much more subjective marker of your effort. Perceived exertion is how hard you feel like your body is working; it is based on physiological sensations experienced during physical activity (i.e. increased heart rate, increased rate of breathing, muscle fatigue, etc.). “Although this is a subjective measure, a person’s exertion rating may provide a fairly good estimate of the actual heart rate during physical activity” (Borg, 1998).
To use the Borg Scale, when exercising, rate your exertion between 6 and 20. According to the scale, each number represents a level of exertion:
BORG SCALE:
6, 7 – very, very light exertion
8, 9 – very light exertion
10, 11 – fairly light exertion
12, 13 – fairly hard exertion
14, 15 – hard exertion
16, 17 – very hard exertion
18, 19, 20 – very, very hard exertion
This is just one of the many ways to measure intensity that is more telling than rate of sweating. Just remember that some individuals can be extremely fit and still sweat profusely, regardless of the intensity of their exercise. This is more related to the number and effectiveness of their sweat glands than their physical prowess.
How To Know When Urine Trouble…

Recently, the daughter of one of my clients posed an interesting question to me, “When I pee…what color should it be?” Part of me laughed at first solely based on how she phrased it (any question that rhymes in my eyes is comedic gold for some reason) but, nevertheless, I can’t pretend like it wasn’t a good question. I mean we all do it. Some of us do it once a day. Some of us do it twice a day. Some of us do it more times a day then they can count on one hand. But how many of us actually stop and think about what we…excrete. Even if we did, how many of us actually know what our urine is supposed to look like besides the proverbial “lemonade color as opposed to an apple cider color”? As true as that is, what about all you jocks who suck down all those multivitamins and are peeing out neon green hulk juice (yea…yea I went there). Or, how about those whose pee produces more foam than actual urine. I apologize for the graphic imagery but the fact of the matter is we all produce different urine based on how we live, but which urine is healthy and which urine is telling you that you’re in trouble?
For those of you who don’t know, urine is a water waste product that passes through your urinary tract and is expelled from your body through your urethra. This is how your body removes noxious chemicals, dead blood cells, excess water, ammonia, proteins, salts, hormones and other excrements the body deems unnecessary. 95% of it is water, but the rest of the contents vary depending on what you have eaten, drank, inhaled or been exposed to. Urine is created and regulated by the kidneys. The kidneys filter the blood and pushes it back into the blood vessels; whatever’s left → urine.
Now as mentioned earlier, urine can come in different colors and consistencies. The most common among these colors is a light yellow urine which typically signifies a healthy urine. It will usually have low odor and little foam. Following that, other colors signify:
• Clear urine – higher concentration of water than waste; could mean you are well hydrated or overhydrated.
• Dark goldish urine – dehydrated; higher concentration of waste than water which also means stronger odor as well.
• Blue urine – usually a side effect of some medications since some oratory meds contain dyes (those little blue pills don’t always start off blue).
• Green urine – usually a by product of foods you have eaten in excess or an excess influx of vitamins and minerals through supplementation.
• Red urine – typically signifies “Hematuria” or blood in the urine. This may be a serious condition related to your kidney, prostate or bladder (might want to seek medical attention immediately).
• Orange urine – could be a sign of Jaundice (which can mix bile into urine); if urine is orange for more than a few days seek med. help).
• Cloudy urine – can be caused by urinary tract infection, bladder infection, kidney stones, gonorrhea or specifically for men a mixing of premature ejaculate in the urine. Seek med help if cloudy urine persists over several bathroom visits.
Honestly, most changes in urine color are harmless and temporary; they are usually the result of certain foods, dyes, supplements or prescription drugs recently ingested. Occasionally though, unusual urine color can indicate an infection or serious illness. You should consult a physician if changes in urine color persist or don’t seem linked to medications or food.
