Misted bathroom mirrors

Do misted bathroom mirrors bother you? I have a great remedy for this. Put a little shampoo in your hand and rub it all over the mirror. Dry the mirror with a towel afterwards. For at least half an hour your mirror will be mist free  .

Why do people yawn?

Let's start watching what yawning, really is. According to the dictionary, yawning is the "frenetic opening of the mouth because of lethargy or fatigue". Yawning is a reflex that originates in the brain stem. A yawn usually begins with a feeling in your mouth. Once it happens, it is almost impossible to avoid: your muscles tighten, your mouth opens and lungs suck air inside. With a full yawn, you close your eyes and you stretch out. Some people get watery eyes from yawning: This is because while yawning, the facial muscles are pressing on the tear duct.

Also during yawning some changes occur in your body: your heart rate goes up (up to 30% more), your blood pressure rises and your small blood vessels constrict.

But why do we do it now?

There is still no agreement why people yawn. There are some theories:

  • People yawn to rise the oxygen level in the blood. This theory assumes that people yawn to increase the oxygen level in the blood and decrease the carbon dioxide content. Yawning would then be a reflex as a result of a high carbon dioxide content in the air. Because everyone in one room breaths the same air, the same reflex will work on several people. That's the reason that it gives you the impression that yawning is contagious, when in fact it's the simultaneous occurrence of the same reflex. This could also explain why people yawn when they are tired or bored. When people are tired or weary, they will automatically breath slowly. Less oxygen reaches the lungs and decreases the oxygen content of the blood. Also, the carbon dioxide content rises. The reflex is now put in motion and you have to yawn. Because many people are tired around the same time, people will therefore yawn at about the same time.
  • Yawning in preparation for exercise. This theory says you're yawning to prepare for your effort.You should therefore only yawn when you have to stay awake. This theory is supported by the fact that a yawn increases heart rate, the blood pressure rises and by yawning you stretch and tighten your muscles.

Unfortunately, none of these theories are supported by science and it remains a mystery why we yawn.

Homemade laundry soap

Recipe for 2.5 liters detergent for white laundry and 2.4 liters for coloured laundry

  • 80 grams grated Marseille or Marseilles Soap Flakes. 
  • 40 grams of soda
  • 5 liters of water (boiling)

Boil 1 liter of water. Add the grated or chopped marseille soap. Stir well and keep stirring until all the soap is dissolved. Add four liters of boiling water.
Pour half of the suds into another pan and add the soda. Soda has a light bleaching effect and therefore it is suitable for white laundry. (Note: not all laundry machines tolerate soda, it may damage the aluminium parts).
Pour the detergent into empty, well-rinsed detergent bottles, specially saved for this occasion. Cool off the detergent and then add the cap on the bottle.

You now have five liters homemade and unscented detergent. This detergent is basically suitable for all laundry at low and at high temperatures (although it is not recommended on some websites to use for towels). The amount to use for doing the laundry is a whole laundry ball.

Good luck!

Vitamin C 1000 mg (ascorbic acid)

I've found a great solution for when you have the flu, the cold, in short terms: when you feel sick. Vitamin C 1000 mg really helps to improve your health, makes the illness go away. I noticed that whenever I use it for 2 or 3 days a week, I hardly have or way less cold problems.

The role of Vitamin C
"Ascorbic acid" or Vitamin C is a water-soluble substance. The main sources of vitamin C are citrus and other fruits. Derived salts of ascorbic acid are called ascorbates (for example, calcium ascorbate).

Why should I take Vitamin C supplements?
Plants, and most of the animals are able to get their own vitamin C to make. Humans, apes, fruit bats and guinea pigs are virtually the only species that have no vitamin C to make, caused by a defective gene in the latest of a series of five genes that provide the enzymes that convert glucose to ascorbic acid.

What does Vitamin C for me?
Vitamin C has many functions:
  • It is involved in the synthesis of collagen, the most common building material of the human body.
  • Functions as a coenzyme in over 800 different biochemical reactions in the body. 
  • It plays an important role in the immune system.

Homemade fabric softener recipe

  • 2 cups baking soda
  • 2 cups vinegar
  • 4 cups water
 Put the ingredients in a large jar (you can use an old gallon milk jug) and be careful! It will fizz up a lot if you go too fast! Shake the jug really well. You can put in a little bit of fragrance if you like, or just use any old fabric softener container (the smell stays forever; after using it 5 times, it still smells just like the store bought stuff).

Use 1/4 - 1/3 cup (or the lid from a fabric softener bottle is perfect, entirely filled up) for every load, and voila!

For about $0.25 you've got about a dozen loads of fabric softener!

Solution for an irritated palate

Have you ever suffered from painful little bumps on your tongue or is your palate irritated? I have a great solution here for you: rinse your mouth with chamomile tea! I even use two bags of chamomile tea if the irritation is a persistent one. Dissolve 1 full teaspoon of salt in the tea and then cool the tea until lukewarm, and rinse your mouth 5 times. Do this  the whole day through and every day until the symptoms have disappeared
Sometimes it's also an indication there is a lack of a vitamin in your body, so use supplements to speed up the healing process. Success guaranteed!

What Is Science?

Science is a systematic and logical approach to discovering how things in the universe work. It is derived from the Latin word “scientia,” which translates to knowledge. Unlike the arts, science aims for measurable results through testing and analysis. Science is based on fact, not opinion or preferences. The process of science is designed to challenge ideas through research. It is not meant to prove theories, but rule out alternative explanations until a likely conclusion is reached.

The Scientific Method

When conducting research, scientists observe the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
The scientific method goes something like this:

  • Make an observation or observations. 
  •  Ask questions about the observations and gather information. 
  • Form a hypothesis — a tentative description of what’s been observed, and make predictions based on that hypothesis. 
  • Test the hypothesis and predictions in an experiment that can be reproduced. 
  • Analyze the data and draw conclusions; accept or reject the hypothesis or modify the hypothesis if necessary.
  • Reproduce the experiment until there are no discrepancies between observations and theory. 
Some key underpinnings to the scientific method:

  • The hypothesis must be testable and falsifiable. 
  • Research must involve deductive reasoning, not inductive reasoning. Deductive reasoning is the process of using true premises to reach a logical true conclusion. 
  • An experiment should include a dependent variable (which does not change) and an independent variable (which does change). 
  • An experiment should include an experimental group and a control group. The control group is what the experimental group is compared against. 
The scientific method and science in general can be frustrating. A theory is almost never proven. A few theories do become scientific laws (such as the law of gravity) and laws are generally considered to be without exception — though in fact even some laws have been modified over time after further testing found discrepancies.

This does not mean theories are not meaningful. For a hypothesis to become a theory, rigorous testing must occur, typically across multiple disciplines by separate groups of scientists. Saying something is “just a theory” is a lay person’s term that has no relationship to science, because in science, a theory is something that is very well supported by observation and experimentation.
