10 Things Only The Colorblind Would Understand

10 Things Only The Colorblind Would Understand

Most people dismiss colorblind people as having a minor problem with red and green. As we shall see below, color vision deficiency (CVD) is not as simple as that! About 8% of males (one in twelve men) have this condition while females suffer more rarely from it (5%). While it is normally an inherited condition, many people may suffer from it later on in life when it is caused by other illnesses such as diabetes or as a side effect of medication. Here are 10 things that the colorblind will understand only too well. It is much more than an eye health problem.

1. People think their world is only in black and white.

When people see the world in black and white, this is not the usual color blindness at all. It is a condition known as achromatopsia and sufferers see the world in different shades of grey. It is rather like viewing the world on an old black and white TV. Fortunately, this condition is very rare and about 1 in 33,000 people are affected.

2. People think the colorblind mix up red and green.

It would be great if it were that simple. They think that they just get their reds and greens confused. But, if you look at the actual cause of color blindness, it tells a different story. The eye has certain nerve cells, called cones, in the retina which can differentiate color. When this is defective, the eye fails to pick up the red elements so the colors of red and green appear to be the same color, a shade of light brown, in many cases. Another example of this red/green color blindness is that there is difficulty in seeing the red element in purple so they will have problems in distinguishing blue and purple.

3. People think it is a minor problem.

Many people dismiss color blindness as a minor disability. But the reality of life tells a different story. Colorblind people have difficulty when they do not realize their child may be getting sunburnt! They may have problems when gardening or when they have to prepare food, not to mention when buying clothes. Laying the table may become problematic when they select the ketchup instead of the chocolate sauce for the dessert. Glasses which can help block glare can usually help a little in better distinction of colors.

4. Colorblind children have problems with food.

Imagine telling a colorblind child to eat up his spinach. The problem is that it appears to him as a rather unattractive brown color which will remind him of something else which is totally disgusting. Similar problems arise when they have to distinguish between an unripe green banana and a nice yellow ripe one.

5. People think that colorblind people can adjust easily.

In many cases, colorblind people adjust and they can tell the difference between red and green traffic lights by their position. But, in many cases, their choice of career can be limited as they will have problems with colors. Becoming a fashion designer, graphic designer or an electrician are usually impossible for people with this condition.

6. Effects on the business and the economy are rarely taken into account.

It is only recently that the idea of changing colors in reports, graphs, presentations, brochures, colored house plans and maps to become more color-blind friendly has begun to make an impact. The truth is that all this colorful information may not be fully accessible for a small minority, around 10%. If the reds and greens are seen as brown, it may be impossible to fully understand a report, graph or a PowerPoint presentation.

7. Food marketing needs to take color blindness more seriously.

We seem to live in a red/green world. From traffic lights to the green economy and food packaging these two colors are everywhere! Let us take an example from supermarkets which use a red/green traffic light system which warn people of levels of fat, salt and sugar. A quick glance to spot the red colors which are unhealthy will do for most of the population. But for those who are suffering from CDV, then they have to read the actually detailed info on the label which is usually far too small anyway. This will affect about 5% of customers.

8. LED lights are infuriating.

Most warning systems use red and green to signal that a device is on standby. The red/green system is also used to indicate whether a battery needs charging. For the colorblind, this can be frustrating to say the least because they never know what is really happening. It is always the same old color!

9. Working in a safe environment is important.

Most employers have never even bothered to reflect on whether their premises are actually safe for the colorblind. Are the warning signs for health and safety using color as the main component? If they are, then this may lead to accidents. Health and safety authorities in the UK warn that under sodium lighting, red is not easily read by people with normal vision.

10. Using a computer with colorblindness.

British Telecom have issued a short guide for web designers to help make their pages more color-blind friendly. Keeping in mind such things as luminosity with background will make the text more readable. This is an excellent initiative because most web designers have never even taken this into consideration. It is high time they did!

Are you or a loved one color blind? How do you cope? Let us know in the comments.

10 Simple Ways To Increase Metabolism Without Working Out

10 Simple Ways To Increase Metabolism Without Working Out

When it comes to increasing your metabolism, getting a good workout a couple of times a week is only one of many players. If you’re not a fan of lifting heavy stuff, then you’re only expending extra energy for that, say, one hour of that specific day. But what about the remaining 23 hours? How can you make sure you’re burning blubber all throughout the day? Here are 10 simple ways to increase your metabolism without working out.

1. Stand More

Many health practitioners claim that sitting is the new smoking. We sit in the office, we sit in the car, we sit when we get home. It’s not only terrible for your health and posture, but you require a lot less energy when seated. So, a good way to ignite the furnace a bit is to stand as much as possible through out the day. You work in an office? Put two boxes under your keyboard or laptop. There are many free solutions to making a standing desk—so you have no excuses. When you’ve gotten used to standing while working you will quickly find that it’s easier to stay engaged as well—you’re less inclined to drift away mentally. In fact, this post was written standing.

2. Gamify Your Life

Toys such as the Fitbit or Nike Fuelband, or apps like Argus, can help you increase your metabolism by giving you an incentive to walk more. Argus, and other apps like it, use the accelerometer in your smartphone to measure your steps and let you know when you’ve hit your daily goal. Fitbit and the Nike Fuelband do the same, but have a host of other functions to make being healthy a tad more fun.

3. Eat Your Veggies

Fibrous vegetables like cauliflower and broccoli increase your metabolism by putting your digestive system on overdrive. It just simply requires more energy to break down the tough fiber of these nutritional powerhouses. You’ll also start feeling like a rock star from the overload of vitamins and minerals from eating more vegetables.

4. Eat Protein

This is one of those rules that’s not to be misunderstood. While it does boost your metabolism to eat more protein, it should be instead of other foods, not on top of other foods. If you’re stuffing your face with a chicken breast when you’re not hungry just to boost your metabolism, you’re doing it wrong. Of the three macro-nutrients—fats, carbs and protein—protein is the one that requires the most energy to break down. So, if you switch out some of those cheese sandwiches with a few hardboiled eggs you’re on the right path.

5. Drink Loads Of Cold Water

Drinking a few glasses of ice-cold water in the morning can boost your metabolism quite effectively. Your body expends energy on constantly staying in homeostasis when it comes to temperature, so if you chug a bunch of icy water you’re making your body expend more energy on keeping itself at the same temperature. Using temperature to expend more energy is called thermogenesis and it’s one of the most efficient ways of cranking up your calorie burning—more on this further down.

6. Spice Up Your Meals

Spices like cayenne, chilli, ginger and turmeric ignite your metabolism and make your meals a bit more exciting. If you make it a habit to add a little bit of spice to each of your meals it can be a habit that turns you into a fat-burning furnace.

    7. Drink Caffeine

    No, drinking loads of coffee is not bad for you. The sugar and heavy cream you could be inclined to chase it down with might be though. Caffeine helps mobilize—that is, get rid of—adipose tissue, or fat. It also helps athletic performance, and some individuals report it to have appetite-curbing effects. If you’re very sensitive to stimulants, try not to have caffeine too close to bedtime though, as it can mess with your sleep.

    8. Plan Your Meals Around Exercise

    I know the title of this post says “…Without Working Out” but this trick technically is more a nutritional trick than an exercise-related one. When you’ve exerted yourself and, hopefully, broken down some muscle fibers, your protein synthesis, or the rate at which you build muscle, increases. So, having heavy meals after a workout will make sure those calories get stored in the right places. This is one of the reasons it’s a good idea to get a heavy session in before the Thanksgiving or Christmas dinner.

    9. Do Intermittent Fasting

    It’s long been said you should always eat a heavy breakfast as it kick starts your metabolic rate. There hasn’t been any study proving this though. There have only been behavioral studies correlating obesity with breakfast skippers, but it’s always been a case of confusing correlation with causation. It’s not the fact that you skip breakfast that makes you fat; it’s the poor food choices you make throughout the rest of your day. Studies have shown that fat burning increases the longer you get into a fast, obviously depending on the body fat level of the individual. In fact, in one study lowered metabolic rate did not occur until 60 hours into a fast. Intermittent fasting is very much one of the bigger wins when it comes to increasing your metabolism.

    10. Use Cold Exposure

    For some reason it’s been common knowledge for a while that sweating increases metabolic rate. Scientist have known for a while though that the opposite is actually true; exposing yourself to cold temperatures increase your calorie burn significantly. Just slight shifts in your home temperature can mean pounds lost or gained when you gather the numbers yearly. How else do you think swimmer Michael Phelps is able to eat 12,000 calories a day? Obviously, he swims hours each day, but it’s not just the exercise he gets from swimming that allows him to consume such quantities of food, it’s also the amount of energy the body has to expend to keep itself at its baseline temperature in the cold water. So, taking ice-cold showers, decreasing the temperature of your home, or swimming in cool pools will help you burn a lot more calories.
