The Math Lovin Momma Reviews: Coffee Joulies

Coffee Joulies

If you’re a coffee drinker and you’re as busy as I am I’m sure you’ve had many days where your coffee is cold by the time you get a chance to sit down and have a sip. I’ve tried multiple insulated travel mugs and they help, but sometimes that still isn’t enough.

Enter Coffee Joulies.

These little guys have been scientifically engineered to make coffee drinking a better experience, and as a little bit a nerd that is one of the biggest reasons I love them!

The Product

So now the all important question, what are Coffee Joulies?

Coffee Joulies are big stainless-steel encased coffee beans you put in your coffee when you pour your cup. They initially cool your coffee to a drinkable temperature in minutes (literally) and then keep it warm much longer than normal.
Tootsie Pop for scale!

Now my fellow nerds are wondering, ‘How does it work?’ Well let me tell you.

So, each Joulie contains something called phase change material. This material absorbs the heat from the coffee and then uses it to keep the temperature perfect for drinking by slowly releasing the heat back into your cup. This phase change material is non-toxic and edible, so it is safe to use in your cup ‘o Joe.

They’re shaped like coffee beans, but they can be used in any hot beverage. Even soup!

Use and Care

The creators of Coffee Joulies recommend one Joulie for every 4 ounces of coffee for maximum effectiveness.

Coffee Joulies are not dishwasher safe, but they are still easy to clean. Just a little hot soapy water after use and they’re good to go for next time!

My Thoughts

I love them!

I had some serious doubts about them when I opened the box. I mean, come on. Giant coffee beans that are somehow going to improve my coffee drinking experience. I was pretty happy with my current insulated travel mug and couldn’t really see how they could be any better.

Despite my doubts I couldn’t wait to try them.

So, the next day, literally, I got my coffee ready like usual but I put three Joulies into my insulated travel mug before I poured in the coffee. Usually my coffee is too hot to drink for at least 30 minutes if I close the lid of my mug, which I do because those 30 minutes usually include travel time to school. Because I had the Joulies in the mug and they were supposed to cool it to drinkable in minutes I had to test the claim. I waited five minutes and took a test sip…

Perfect. Maybe a touch on the warm side but definitely drinkable without burning my tongue.

That first day I also drank my coffee slower than usual so I could test the claim that it kept it warm longer. I got to school at 7:30, about half an hour after pouring my coffee, at 11:30 it was still very warm. I left a bit in my mug so I could test it again at the end of the school day. At 3:30 when I was packing to head home I gave my coffee a sip and it was still warm(ish). Definitely not hot anymore, not anywhere near perfect temperature but it was most assuredly not cold.

Ok, so pretty impressive but I still had my doubts. What about in a non-insulated mug? On the weekends and days I don’t have to teach I use a normal ceramic mug and my coffee quickly goes from drinkably warm to cold faster than I can drink it usually.

The next Saturday morning I got out my mug and two Joulies. (I have a big mug…) About two minutes after pouring the coffee was drinkable.I tested it at 15 minute intervals for the next hour and it was comfortably warm for at least the first half hour. The last half hour it seemed to cool more quickly but there was also less liquid in the mug and the Joulies were exposed to the air. I’m not a scientist but it seems reasonable to think that could cause them to cool more quickly.

Overall, I’m really happy with my set of Coffee Joulies and would recommend them to anyone who needs a better way to keep their coffee at the perfect drinkable temperature for longer!

An added bonus is that they’re made in the U.S., keeps your coffee hot and keeps our economy going!

Measles: The Facts

Because I live in a country that had considered the measles virus eliminated since the year 2000 I have zero first-hand experience with the disease. I do know, however, that the disease has made a comeback in recent years because of the influx of people choosing not to vaccinate their children, for a variety of reasons. With all the media coverage and discussion going on about the most recent measles outbreak, I decided to do my own research to find out more about the disease.

The Virus

What is Measles?

Measles, caused by the measles virus, is a highly contagious infection which attacks the respiratory system . Most of the initial symptoms of measles are similar to that of the flu and include high fever (over 104.0° F), cough, runny nose, and red, watery eyes. A few days after initial symptoms appear, an infected person may develop small white spots inside the mouth, these are known as Koplik’s spots. Three to five days after the initial onset an infected person will notice a skin rash.

Koplik spots

The rash usually begins around the hairline and on the face as flat red spots. From there it spreads downward to the neck, arms, chest, stomach, back, legs, and feet. The flat red spots may have smaller raised bumps that appear on top as well.

Measles rash

Generally, the onset of the rash is accompanied by a fever spike to over 104.0 ° F.

How is Measles Transmitted?

The measles virus lives in the mucus of the nose and throat of infected persons and so is mainly passed through coughing and sneezing. The virus stays alive for up to two hours on surfaces and in the air where an infected person has coughed or sneezed.  Other people in the area who breath the contaminated air or touch the contaminated surface can become infected. The virus can also be passed through contact with saliva and nasal secretions.

According to the CDC website,

“Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infected.”

Persons infected with the measles virus can infect other people from four days before until four days after the appearance of the rash.  So a person could be a carrier of the virus without showing any symptoms and still be contagious.

What are the Complications that Come From Measles?

Measles can be very serious for anyone that is infected, however, those younger than five and older than 20 have a higher chance of developing complications from the disease. About 30% of measles cases report complications of some kind, according to the CDC.

Measles Complications by Age Group

Some of the most common complications include ear infection and diarrhea. Ear infections are seen in 1 in 10 children (10% of the infected) with measles and diarrhea is reported in less than 10% of cases. If not treated properly, ear infections can lead to permanent hearing loss.

As with many diseases there are also some serious complications that can arise from measles as well, including pneumonia and encephalitis. Pneumonia, an infection of the lungs, is reported in 1 in 20 children (5% of the infected) and is the leading cause of death in this age group. Encephalitis (swelling of the brain) is reported in 1 out of 1,000 children (0.001% of the infected) and can cause convulsions, deafness, and mental retardation.

Measles in pregnant women  can cause premature birth and/or low-birth weight for the baby.

Statistically, in the U.S. one of every 1,000 (0.001%) cases of the measles one or two of the infected will die. As with all the complications death is most likely in children and older adults.

Even after a person has recovered from the measles there is a chance of them developing complications from the disease in the future.  Subacute sclerosing panencephalitis (SSPE) can develop 7 to 10 years after a person has had the measles. SSPE is a rare, but fatal disease affecting the central nervous system. Since the elimination of measles in the U.S. (2000) there have been few reported cases of SSPE, but from 1989 to 1991 between 4 and 11 cases out of every 100,000 were considered to be at risk for developing SSPE. The risk was higher for those contracting measles before the age of two.

 The Vaccine

Measles can be prevented through the use of the MMR (Measles, Mumps, Rubella) vaccine. Through vaccine usage in the U.S. there are more than 99% fever cases of Measles than before the vaccine was introduced, however, measles is still very common in other countries.

Since the virus is highly contagious it can spread very quickly in areas where there are many unvaccinated persons.

According to the CDC website:

“Worldwide, an estimated 20 million people get measles and 146,000 people die from the disease each year—that equals about 440 deaths every day or about 17 deaths every hour.”

In case you’re not a math lover or just don’t want to figure it out, that is a 0.0073% mortality rate. That is over seven times higher than the U.S. mortality rate.

What Can I Do to Protect My Family?

The CDC recommends that all children get two doses of the MMR vaccine, the first between 12 and 15 months old and the second between 4 and 6 years old. The second dose of the vaccine can be given earlier if desired, as long as 28 days has passed since the first vaccine was administered.

A child traveling abroad who is between 6 and 11 months should receive one dose of the vaccine, followed by the two doses recommended above.

Are There Reasons to Not Get the Vaccine?

Turns out, as with nearly every medical practice, there are exceptions to the CDC recommendation. Some people should not get the vaccine or wait until a later time to get the vaccine.

These groups of people include:

  • Anyone who has had a life-threatening allergic reaction to the antibiotic neomycin or any other part of the MMR vaccine.
  • Anyone who has had a life-threatening allergic reaction to a prior dose of the MMR vaccine.
  • Pregnant women should wait to get the vaccine until after giving birth. (Women should also avoid getting pregnant within 4 weeks of receiving the vaccine.)
  • Someone who is sick at the time the dose is scheduled to be administered may be advised, by their physician, to wait until they are well.
  • Alert the physician if the person getting the vaccine:
    • Has HIV/AIDS, or another disease that affects the immune system
    • Is being treated with drugs that affect the immune system
    • Has any kind of cancer
    • Is being treated for cancer with radiation or drugs
    • Has ever had a low platelet count
    • Has gotten another vaccine within the past 4 weeks
    • Has recently had a transfusion or received other blood products

    Any of these might be a reason to not get the vaccine, or delay vaccination until later. (Taken direct from the CDC website.)

What are the Risks?

As with any medicine, there are some possible side effects of the MMR vaccine. The risk of the MMR vaccine causing serious harm, or death, is very small so getting the vaccine is much safer than getting Measles, Mumps, or Rubella.

The possible mild reactions include a fever (about 17% of those vaccinated), a mild rash (about 5% of those vaccinated), and swelling of the glands in the cheek or neck (about 1.5% of those vaccinated).

The possible moderate reactions include seizures caused by fever (about 0.0003% of those vaccinated), temporary joint pain and stiffness (up to about 25% with higher chances in teen and adult women), and temporary low platelet count which could lead to a bleeding disorder (about 0.00003% of those vaccinated).

There is also a very small chance of a sever allergic reaction in less than 1 out of a million doses(less than 0.000001%).

According to the CDC website, several other severe problems have been reported after a child gets MMR vaccine, including:

  • Deafness
  • Long-term seizures, coma, or lowered consciousness
  • Permanent brain damage

However, these are so rare that it is hard to tell whether they are caused by the vaccine.

Does the Measles Vaccine Cause Autism?

No. Because science. (As Papa Dragon would put it.)

But seriously, there is no scientific evidence to support the theory that vaccines cause autism. Here is a link to a great pdf resource citing numerous independent studies that show there is no connection between the MMR vaccine and autism.
