For that you’ll first have to understand what happens when we breathe. Normally, when you breathe in, you inhale oxygen and your body uses it up. The body makes a waste product called as carbon dioxide that is exhaled from the lungs when you breathe out.
When you are sleepy, bored or tired, you breathe more slowly. Your body requires oxygen and needs to throw out the carbon dioxide. So, your brain makes you take an extra breath, which is deep and long called a yawn, so that you can take in more of oxygen and give out carbon dioxide fully.
Bottom line is Alcohol acts quickly and evaporates, however it smells, stings and leaves skin dry and hard. Hydrogen peroxide will oxidize (make bubbles) and eat away at bacteria/fungus. It also is oderless and generally painless. You can use alcohol on an open wound, it will hurt but it will be clean quickly. If you think your wound is getting infected or has a redish tone to the surrounding skin, use HP. It will bubble up as it kills the infecting bacteria. Rinse and repeat.
Rubbing alcohol is recognized as a rubefacient because it evaporates quickly and is used to cool and soothe skin. A rubefacient is a substance for external application that produces redness of the skin e.g. by causing dilation of the capillaries and an increase in blood circulation. It is, however, more widely used as an antiseptic for sterilizing surfaces or cleaning minor cuts or abrasions.Isopropyl rubbing alcohol can also be supplied in a 99% concentration. This product can also be used to harden skin, such as in the case of the feet of novice hikers, or the fingertips of guitarists.
Hydrogen peroxide has been used as an antiseptic and anti-bacterial agent for many years due to its oxidizing effect. While its use has decreased in recent years with the popularity of better-smelling and more readily-available over the counter products, it is still used by many hospitals, doctors and dentists in sterilizing, cleaning and treating everything from floors to root canal procedures.Like many oxidative antiseptics, hydrogen peroxide causes mild damage to tissue in open wounds, but it also is effective at rapidly stopping capillary bleeding (slow blood oozing from small vessels in abrasions), and is sometimes used sparingly for this purpose, as well as cleaning.
Do Apples Have Caffeine?
No. Not even a little bit. Apples, as a pomaceous fruit, do not naturally contain caffeine. They do, however, have about 13 grams of sugar – natural sugar, which is much healthier than the 4 grams of Sweet’N Low mixed into your daily coffee. So despite the high sugar levels, eating an apple is a much healthier alternative to drinking coffee. The sugars are also one of the main reasons apples have similar effects to caffeine.
Vitamins from apples, specifically the skin, are released slowly throughout the body, making you feel more awake. There is no jolt of energy. No mood swings. And, most importantly, no crash. The results wear off as gradually as they started. With this argument, though, any healthy snack can help fight sleepiness. (Snacks that are too sugary or fatty will actually have the opposite effect, causing your body to crash.) So why apples? What do they have that other healthy foods don’t?
Saturn, the ringed beauty of the solar system, will put on its best show of the year for stargazers tonight (May 10), and you can catch live telescope views of the planet online.
The online Slooh community telescope will offer live views of Saturn from a remotely operated telescope in the Canary Islands, off the western coast of Africa, as the ringed planet reaches opposition, a point in its orbit when it is on the opposite side of Earth from the sun.
Slooh’s feed of Saturn will begin at 9:30 p.m. EDT (0130 May 11 GMT) and feature commentary from astronomer Bob Berman and Slooh host Geoff Fox. You can also watch the Saturn webcast live on Space.com in addition to the Slooh website. Viewers will be able to ask questions about Saturn at opposition using the Twitter hashtag #Slooh.
