This fusion process not only heats the Sun, it makes the sunlight we see here on Earth. This sunlight travels the speed of light which is 186,282 miles per second or 299,792,458 meters per second. This means the light from the Sun takes 8.4 minutes to travel 93 million miles to Earth. If the world’s fastest land animal were to travel that same distance, it would take a cheetah over 151 years to reach the Earth running about 70 mph nonstop!
Ultraviolet radiation: Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation can burn the skin and cause skin cancer.
Ultraviolet radiation is made up of three types of rays — ultraviolet A, ultraviolet B, and ultraviolet C. Although ultraviolet C is the most dangerous type of ultraviolet light in terms of its potential to harm life on earth, it cannot penetrate earth’s protective ozone layer. Therefore, it poses no threat to human, animal or plant life on earth.
Ultraviolet A and ultraviolet B, on the other hand, do penetrate the ozone layer in attenuated form and reach the surface of the planet. Because ultraviolet A is weaker than ultraviolet B, scientists long blamed ultraviolet B as the sole culprit in causing skin cancer in persons with a history of sunburn and repeated overexposure to ultraviolet radiation. Recent research, however, has also implicated ultraviolet A as a possible cause of skin cancer.
Photosensitivity refers to various symptoms, diseases and conditions caused or aggravated by exposure to sunlight.
Photosensitivity is characterized into many groups:
PLE generally affects adult females aged 20–40, although it sometimes affects children and males (25%). It is particularly common in places where sun exposure is uncommon, such as Northern Europe, where it is said to affect 10–20% of women holidaying in the Mediterranean area. It is less common in Australasia. It has also been reported to be relatively common at higher altitudes compared to sea level.
PLE can occur in all races and skin phototypes and may be more prevalent in skin of colour than in white skin. There is a genetic tendency to PLE, and it is sometimes associated with or confused with photosensitivity due to lupus erythematosus (which generally is more persistent than PLE).
Genetic factors may be important with many affected individuals reporting a family history of PLE. Native Americans have a hereditary form of PLE (actinic prurigo).
PLE is caused by a delayed hypersensitivity reaction to a compound in the skin that is altered by exposure to ultraviolet radiation (UVR). UVR leads to impaired T cell function and altered production of cytokines in affected individuals. There is a reduction in the normal UV-induced immune suppression in the skin. This has been suggested to be either due to oestrogen or deficiency of vitamin D.
The rash is usually provoked by UVA (in 90%). This means the rash can occur when the sunlight is coming through window glass, and that standard sunscreens may not prevent it. Occasionally, UVB and/or visible light provoke PLE.
PLE may be a rare occurrence in the individual concerned or may occur every time the skin is exposed to sunlight. In most affected individuals, it occurs each spring, provoked by several hours outside on a sunny day. If further sun exposure is avoided, the rash settles in a few days and is gone without a trace within a couple of weeks. It can recur next time the sun shines on the skin. However, if the affected area is exposed to more sun before it has cleared up, the condition tends to get more severe and extensive with longer to heal.
Treatment: One is prevention and avoid sun light when it is out the strongest in ultra-violet rays 12pm to 3pm and always use sunscreen.
The following treatments may reduce the severity of PLE:

“Smoking cessation [stopping smoking] represents the single most important step that smokers can take to enhance the length and quality of their lives.”
The U.S. Surgeon General and American Cancer Society
Not everyone gains weight when they stop smoking On average, people who quit smoking gain only about 10 pounds You are more likely to gain weight when you stop smoking especially if you stop smoking when you have smoked for 10 to 20 years or smoked one or more packs of cigarettes a day. You can control life. Although you might gain a few pounds, remember you have stopped smoking and taken a big step towards a healthier life.
What causes weight gain after quitting? When nicotine, a chemical n cigarette smoke, leaves your body, you may experience: Short-term weight gain. The nicotine kept your body weight low, and when you quit smoking your body returns to the weight it would have been had you never smoked.
You might gain 3-5 pounds due to water retention during the first week after quitting.
A need for fewer calories when quitting to smoke. After you stop smoking, you may use fewer calories than when you were smoking.
Will this weight gain hurt your health?
The health risks of smoking are far greater than the risks of gaining 5 to 10 pounds. Smoking causes more than 400,000 deaths each year in the United States. You would have to gain 100 to 150 lbs after quitting to make your health as high as when you smoked. The health risks of smoking and the benefits of quitting are listed below.
The Health Risks of Smoking
**Your Heart Rate Increases
**You expose yourself to some 4000 chemicals in cigarette smoke and 40 of these chemicals cause cancer.
**You are much more likely to get lung cancer compared to a nonsmoker. Men are 22 times more likely to develop lung cancer, while women who smoke are 12 times more likely.
**You are twice as likely to have a heart attack as a nonsmoker.
**You increase your risk for heart attack as a nonsmoker.
**You increase your risk for heart disease, stroke, some types of cancer (lung especially), emphysema, chronic bronchitis, and other lung diseases.
The Benefits of Quitting
When you quit smoking your body begins to heal from the effects of the nicotine within 12 hours after your last cigarette.
Your heart and lungs start repairing the damage caused by cigarette smoke.
You breathe easier and your smoker’s cough starts to go away.
You lower your risk for illness and death from heart disease, stroke, chronic bronchitis, emphysema, lung cancer, and other types of cancer.
You contribute to cleaner air, especially for children who are at risk for illnesses because they breathe others cigarette smoke.
Adapted from the National Cancer Institute’s “Smoking:Facts and Tips for Quitting”
“Because even healthy people can fall victim to summer heat, take the following precautions to reduce your risk:
-Drink plenty of water or other non-alcoholic beverages
-Wear lightweight, loose-fitting clothing that is light in color
-Reduce strenous activities or do them during the cooler parts of the day (not during 12pm-4pm the hottest time of a day).”
CDC Center for Disease Control and Prevention
People’s biggest mistake by far is drinking and boating. People get out there and drink alcohol all day in the sun, and you end up with the same accidents you have with driving — with the added risks of falling out of boats, getting hit by propellers, and drowning.
It’s also easy to get lax about life jackets. Kids need to have them on all the time. Even if having them under the seat fulfills the law, in an accident, chances are anyone who doesn’t know how to swim won’t be able to get to them in time. When you are going to be out on a boat or at the beach with a child, you take on the responsibility to maintain the safety of that child and basic lifesaving skills are a must, not a luxury; especially for parents. The courses are easy, usually just one day or half a day and you may save your child’s LIFE or the child you take the responsibility in caring for. There’s no mouth-to-mouth [resuscitation] anymore if you are not trained — just chest compressions but if you get BCLS certified (basic care in life support) your CPR certified.
You can find first aid, cardiopulmonary resuscitation (CPR), and other emergency lifesaving courses near you with the American Heart Association’s ECC (Emergency Cardiovascular Care) Class Connector tool online at americanheart.org. or near you where you live.
We know almost every homeowner loves the sight of a pristine, neatly mowed yard. But in their haste to get that lawn in shape, some people forget to take precautions. “In the warmer months we see lots of mower injuries to toes, hands, and fingers getting caught in blades, and things like rocks and sticks getting flung out of them. People will start tinkering with the mower and reach under it to unclog it, and forget there’s a spinning blade there or take the key out when going under to see what clogged the blade from working. Those can be preventative moves and result in hideous injuries for some permanent and with others temporary.
They’re also hard to repair, because not only can whirling blades cause complex lacerations and fractures, but they can bury contaminants like grass and dirt in the wound putting the wound at risk for infection. To be safe:
Wear closed-toed shoes — preferably with a steel toe — when you mow, along with goggles or sunglasses, gloves, and long pants that will protect you from flying debris.
Keep kids away from the push mower and off the riding mower. Riding mowers are not just another ride-on toy.
Get a professional to service your mower or learn how to do it properly. Important: Disconnect the spark plug to prevent it from accidentally starting. Turning a push mower’s blade manually can ignite the engine.
You’ve romped outdoors with the kids all day, and your water bottle ran dry long ago. Suddenly you feel dizzy and lightheaded, and your mouth tastes like cotton. You’re dehydrated — meaning you haven’t taken in enough fluids to replace those you’ve been sweating out.
People can get dehydrated any time of year, but it’s much more common in the summer months, when they are active outdoors in the warm sun. Heatstroke is the most severe form of dehydration. That’s when your internal temperature rises to dangerously high levels. Your skin gets hot, but you stop sweating. Someone with heatstroke may pass out, have hallucinations, or suffer seizures.
Preventing dehydration and heatstroke is so easy: Drink plenty of fluids, especially water, take regular breaks in the shade, and try to schedule your most vigorous outdoor activities for times when the heat isn’t so strong, such as early morning or late afternoon.
For persons suffering more serious dehydration or heatstroke, get them indoors, have them lie down, and cool them off with ice packs and cool cloths. Someone who is seriously affected by the heat may need intravenous fluids in the ER.
With all the skin cancer warnings, you’d think Americans would be getting fewer sunburns, not more. But you’d be wrong. The percentage of adults nationwide who got at least one sunburn during the preceding year rose from 31.8% in 1999 to 33.7% in 2004, according to the CDC.
Your risk for melanoma doubles if you’ve had just five sunburns in your life. A sunburn is a first-degree burn, right up there with thermal burns. Also, we even see some second-degree thermal burns, often when people are out drinking or falling asleep in the sun and don’t realize how long they’ve been out there.
In addition to practicing “safe sun” — wearing sunscreen that protects against both UVB and UVA rays, long-sleeved shirts, and wide-brimmed hats, and staying out of blistering midday rays — there are things you can do to treat a severe sunburn, Stanton says:
-Drink water or juice to replace fluids you lost while sweating in the hot sun.
-Soak the burn in cool water for a few minutes or put a cool, wet cloth on it.
-Take an over-the-counter pain reliever, such as acetaminophen.
-Apply an antibiotic ointment or an aloe cream with emollients that soften and soothe the skin directly to the burned area.
-You’re going to have a pretty miserable 12 to 24 hours with the initial symptoms no matter what you do.
Anything that has mayonnaise, dairy, or eggs in it and any meat products can develop some pretty nasty bacteria after only a couple of hours unrefrigerated. Every summer we’ll have five or six people coming in from the same reunion or family picnic with food poisoning symptoms.
To prevent food poisoning, follow the U.S. Department of Agriculture’s advice to:
Mild cases of food poisoning can be cared for at home, Stanton says. Avoid solid foods, and stick with small, frequent drinks of clear liquid to stay hydrated. Once the nausea and vomiting have eased, you can try bringing food back into your diet — slowly and in small, bland portions (Grandma knew what she was talking about when she recommended tea and toast to settle an upset stomach). If symptoms persist for more than a couple days (or more than 24 hours in small kids), see a doctor.
Independence Day arrives. Many people love fireworks, but fireworks don’t necessarily love them back. Nearly 9,000 individuals were injured by fireworks in 2009, according to the U.S. Fire Administration, and two were killed. We see pretty significant hand and eye injuries from fireworks every summer. The safest way to watch fireworks is at a professionally sponsored display. At least six states ban all consumer fireworks, and several more allow them only with limitations. But if you can buy fireworks legally and want to set off a few at home, take these precautions:
To care for a fireworks burn, wrap it in a clean towel or T-shirt saturated with cool water and get to an emergency room to have the injury checked out.
” The most common types of breast cancer are ductal carcinoma in situ, invasive ductal carcinoma, invasive lobular carcinoma, medullary carcinoma, and Paget disease of the nipple (see definitions under these headings). “

Can a healthy diet prevent breast cancer?
Eating a diet rich in fruits and vegetables hasn’t been consistently shown to offer protection from breast cancer. In addition, a low-fat diet appears to offer only a slight reduction in the risk of breast cancer.
However, eating a healthy diet may decrease your risk of other types of cancer, as well as diabetes, heart disease and stroke. A healthy diet can also help you maintain a healthy weight — a key factor in breast cancer prevention.
Is there a link between birth control pills and breast cancer?
A number of older studies suggested that birth control pills slightly increased the risk of breast cancer, especially among younger women. In these studies, however, 10 years after discontinuing birth control pills women’s risk of breast cancer returned to the same level as that of women who never used oral contraceptives. Current evidence does not support an increase in breast cancer with birth control pills.
Be vigilant about breast cancer detection. If you notice any changes in your breasts, such as a new lump or skin changes, consult your doctor. Also, ask your doctor when to begin mammograms and other screenings.
Once you’ve been diagnosed with breast cancer, your doctor works to find out the specifics of your tumor. Using a tissue sample from your breast biopsy or using your tumor if you’ve already undergone surgery, your medical team determines your breast cancer type. This information helps your doctor decide which treatment options are most appropriate for you.
Here’s what’s used to determine your breast cancer type.
Whether your cancer is invasive or noninvasive helps your doctor determine whether your cancer may have spread beyond your breast, which treatments are more appropriate for you, and your risk of developing cancer in the same breast or your other breast.
The type of tissue where your breast cancer arises determines how the cancer behaves and what treatments are most effective. Parts of the breast where cancer begins include:
