Not only is it important but it’s interesting to find out more about how we operate and how things work… Let’s take a look at todays questions and see if you learn a thing or two… Enjoy!
Why Do We BLUSH?
So you’re at work when someone attractive walks in, and woohooo you’re filled with excitement as if you were a kid in a candy shop… ‘Well, hello good looking!’ you think to yourself. They slowly work their way to you and say “Hi, may you help me?” and what happens to you? You get tongue-tied as your brain and heart are on panic mode…’Abort, jump ship, run for the hills your mind is scrambling just to come up with something to say ‘just say hi, just say hi!’ You find the words to mouth “Hi, yes I can help you!” as you feel yourself turning red-hot and wishing you could de-cloth and jump into an ice bucket. BUT you can’t you must stay there in the awkward blushing phase as you begin to fan yourself to cool down and help this person who has preoccupied your mind with fun thoughts!
Oh that good ole’ blushing… Let’s find out the science behind it!
Blushing is the reddening of a person’s face due to psychological reasons. It is normally involuntary and triggered by emotional stress, such as that associated with embarrassment, anger, or romantic stimulation.
Severe blushing (flushing) is common in people who suffer social anxiety in which the person experiences extreme and persistent anxiety in social and performance situations. rosacea, Idiopathic craniofacial erythema is a medical condition where a person blushes strongly with little or no provocation. Just about any situation can bring on intense blushing and it may take one or two minutes for the blush to disappear.Wikipedia
Scientists believe blushing is related to social interaction which allows others to know how you feel without having to verbally tell them. This can help with survival instincts as it makes others aware of your feelings and they can react to you in a more forgiving nature. The Common blushing triggers include embarrassment, meeting someone important, receiving a compliment, and when experiencing a strong emotion in a social situation. LiveScience.com
When you’re experiencing something to make you blush, your body releases adrenaline. This hormone acts as a natural stimulant and has an array of effects on your body that are all part of the fight-or-flight response. Adrenaline speeds up your breathing and heart rate to prepare you to run from danger. It causes your pupils to grow bigger to allow you to take in as much visual information as possible. It slows down your digestive process so that the energy can be redirected to your muscles. All of these effects account for the jolt you feel when you find yourself embarrassed.
Adrenaline also causes your blood vessels to dilate (called vasodilation), in order to improve blood flow and oxygen delivery. This is the case with blushing. The veins in your face respond to a signal from the chemical transmitter adenylyl cyclase, which tells the veins to allow the adrenaline to do its work. As a result, the veins in your face dilate, allowing more blood to flow through them than usual, creating the reddened appearance that tells others you’re embarrassed. In other words, adrenaline causes more local blood flow in your cheeks. science.howstuffworks.com
What Do Your Nails Say About Your Health?
If you are a hypochondriac skip this section! (just saving you from a world of worry!) The information presented is from WebMD and they stated that ‘the information provided while it can be an indication of a health problem, there are some who may have nail trouble but have NO health issues’…so keep that in mind! If you’re worried set an appointment with a dermatologist. Also If you believe you might have an underlying health problem while looking at your nails, make sure you have other symptoms as well (take note of your health concerns such as excessive fatigue, jaundice, loss of appetite, etc…)
- Pale colored nails could indicate problems with: Liver disease, anemia, congestive heart failure, and malnutrition.
- White nails from the root to the rim, then at the rim it changes to darker color/skin color, this can indicate: Liver problems like Hepatitis.
- Yellow nails indicate: Mostly a fungal infection- when infection gets worse the nail bed may retract, and nails may thicken and crumble. In more serious cases (rare) it can indicate severe thyroid disease, lung disease, and diabetes or psoriasis.
- bluish nails can mean not enough oxygen is getting to the body and can be caused by a lung problem like emphysema, also heart problems.
- If the surface is rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis. Discoloration of the nail is common; the skin under the nail can seem reddish-brown.
- cracked or slip nails… Dry, brittle nails that frequently crack or split have been linked to thyroid disease. Cracking or splitting combined with a yellowish hue is more likely due to a fungal infection.
- Dark lines beneath the nail… should be investigated as soon as possible. They are sometimes caused by melanoma, the most dangerous type of skin cancer.
Eat Bananas! (In Moderation)
The Benefits Of Bananas: by LiveScience.com
Bananas are good for your heart. They are packed with potassium, a mineral electrolyte that keeps electricity flowing throughout your body, which is required to keep your heart beating. Bananas’ high potassium and low sodium content may also help protect your cardiovascular system against high blood pressure, according to the FDA.
Depression and mood
Bananas can be helpful in overcoming depression “due to high levels of tryptophan, which the body converts to serotonin, the mood-elevating brain neurotransmitter,” Flores said. Plus, vitamin B6 can help you sleep well, and magnesium helps to relax muscles.
Digestion and weight loss
Bananas are high in fiber, which can help keep you regular. One banana can provide nearly 10 percent of your daily fiber requirement. Vitamin B6 can also help protect against type 2 diabetes and aid in weight loss, according to Flores. In general, bananas are a great weight loss food because they taste sweet and are filling, which helps curb cravings. They also help sustain blood sugar levels during workouts.
Carrots may get all the glory for helping your eyes, but bananas do their share as well. The fruits contain a small but significant amount of vitamin A, which is essential for protecting your eyes, maintaining normal vision and improving vision at night, according to the National Institutes of Health. Vitamin A contains compounds that preserve the membranes around your eyes and are an element in the proteins that bring light to your corneas. Like other fruits, bananas can help prevent macular degeneration, an incurable condition, which blurs central vision.
Bananas may not be overflowing with calcium, but they are still helpful in keeping bones strong. According to a 2009 article in the Journal of Physiology and Biochemistry, bananas contain an abundance of fructooligosaccharides. These are nondigestive carbohydrates that encourage digestive-friendly priobotics and enhance the body’s ability to absorb calcium.
Some evidence suggests that moderate consumption of bananas may be protective against kidney cancer. A 2005 Swedish study found that women who ate more than 75 servings of fruits and vegetables cut their risk of kidney cancer by 40 percent, and that bananas were especially effective. Women eating four to six bananas a week halved their risk of developing kidney cancer.
Bananas may be helpful in preventing kidney cancer because of their high levels of antioxidant phenolic compounds.
