London Drugs bettercare – First Aid & Medication Safety

Being in charge of your family’s health is a full-time job. There are always scrapes, stings, minor burns, and other emergencies that need to be addressed. The best way to tackle these problems is to prepare for them before they occur by investing the time to learn about first aid techniques and medication safety to make your home a safe haven.

Dangerous situations can happen anytime and virtually anywhere. In Canada, in most areas emergency assistance can by reached by dialling 911 on any telephone, including pay phones and cellular phones. Everyone in your household, even young children, should be instructed to call 911 in case of emergency. If 911 service is not available in your area, find out the number to call in emergencies and post it—along with other emergency information, such as doctor’s name and phone number—near your telephone for easy reference. Also keep your London Drugs pharmacy number by the phone. Our pharmacists are medication experts who can answer your questions whenever you have them—not just in emergencies.

Consider taking a first aid course from an organization such as St. John’s Ambulance or the Red Cross. This will give you the opportunity to practice your first aid skills in a calm environment so that you’ll be better prepared if an emergency does occur. You may also want to stop by your local bookstore and pick up a good first aid manual for your home and car.

Most first aid situations around the home aren’t emergencies and don’t require a 911 call. They are usually the minor cuts, bruises, and burns that are part of everyday life. Here are some tips for dealing with some of the more common situations.

Burns
Minor, or first-degree, burns usually turn the skin red and can sometimes cause swelling and pain. In the event of a minor burn, take the following steps:

  • Cool the burn. Hold the burned area under lukewarm running water for 15 to 30 minutes. Cooling the burn reduces swelling by taking the heat away from the skin. Don’t put ice on the burn, as this may cause frostbite, further damaging the skin.
  • Apply lotion. Once a burn is completely cooled, apply an aloe vera lotion, an antibiotic ointment, or a moisturizer to prevent dryness and make the injury feel more comfortable. However, do not coat the burn with butter or a thick ointment such as petroleum jelly, because this traps the heat in the skin.
  • Cover the burn. Wrap a sterile gauze bandage loosely around the burned area. Bandaging keeps air off the area, reduces pain, and protects blistered skin.

Minor burns usually heal in about one to two weeks. Watch for signs of infection such as increased pain, redness, fever, swelling, or oozing. If infection develops, seek medical help immediately.

Cuts and Scrapes
Most small cuts and scrapes don’t require a trip to the emergency room, but it is important to care for them properly to avoid infection and other complications. The following guidelines can help you treat simple wounds:

  • Stop the bleeding. Use gentle pressure applied over a clean cloth or bandage.
  • Clean the wound. Rinse the wound with clear water; soap may irritate the injury.
  • Apply an antibiotic. After you clean the wound, apply a thin layer of antibiotic
    cream to help keep the surface moist and kill bacteria that could cause infection.
  • Cover the wound. Bandages help the wound stay clean, keeping harmful
    bacteria out.
  • Change the dressing. Change the bandage at least once daily to keep it clean
    and prevent infection.
  • Get medical treatment for deep wounds. A wound that cuts deeply through the skin may require stitches. If in doubt, see your doctor immediately.
  • Watch for signs of infection. Visit your doctor if the wound doesn’t heal properly or if you notice any redness, warmth, or swelling.
  • Get a tetanus shot. Doctors recommend getting one every ten years.

Poisoning
Keeping dangerous substances locked away is the best way to prevent poisoning. However, if you suspect someone has been poisoned, look for the following signs:

  • Burns or redness around the mouth and lips.
  • Breath that smells like chemicals such as gasoline or paint thinner.
  • Burns, stains, and odours on or around the person.
  • Vomiting, difficulty breathing, sleepiness, confusion, or other unexpected signs.

If you believe someone in your family has been poisoned, follow these steps:

  • Call your local poison control centre and follow their instructions. Directions on the product label telling you what to do may be inaccurate or out of date.
  • If the victim is unconscious or has swallowed a substance that is acidic, caustic, or has a petroleum base (such as gasoline or household cleaners), get the victim to the hospital immediately. Do not induce vomiting.
  • If the victim has not passed out and if the substance is something that is normally swallowed (such as medicine), the poison control centre may tell you to induce vomiting.
  • Get medical attention immediately. If you have identified the poison, bring the container with you. If you don’t know what the poison is but the person has vomited, bring a sample of the vomit with you for analysis.

Medication Safety

Chances are your family has a cabinet full of medications—from over-the-counter products to prescription drugs. Lurking in the back corner of your medicine cabinet may be some expired medications, and perhaps some prescription drugs you no longer use.

An important step in the proper use of medications is to educate yourself about the specific drugs you and your family are taking. All of your family’s medications need to be carefully organized to avoid dangerous mistakes. Here are a few tips to help keep you and your family safe:

  • Storage: Ask your doctor or pharmacist for directions on how to store your medications. Certain medications need to be refrigerated and others should be kept in a cool, dry place. Make sure that all medications are in child-proof containers and are stored well out of your children’s reach.
  • Drug interactions: If you’re taking more than one medication, ask your pharmacist to check for any possible drug interactions.
  • Side effects: If you develop what you think is a side effect, contact your doctor or pharmacist immediately. There may be another medication with fewer side effects that can be substituted.
  • Allergic reactions: Allergic reactions from medications may include difficulty breathing, skin rashes, itching, swelling, racing heartbeat, nausea, severe diarrhea, and feeling faint. Tell your doctor or pharmacist if you experience any of these symptoms after taking a new medicine. If the reaction involves difficulty breathing, call for emergency assistance immediately.
  • Expiry dates: Unused and expired medications can be dangerous. Do a yearly inventory of your medicine cabinet and dispose of outdated or unused medications.
  • Never share: The medications prescribed by your doctor were meant to treat your particular medical problem. Never share your medication with anyone else.
  • Follow directions: Read the labels carefully and follow the directions to the letter. Be sure to finish the full course of your medication. Stopping a medication too early can cause the illness to return or make it more difficult to treat.

London Drugs bettercare – Back Care


If you suffer from back pain, you’re not alone. Over 80% of adults experience at least one bout of back pain at some time in their lives, and back pain is a leading cause of work-related disability. And the most common site of back pain is the lower back, because it bears most of the stress and weight.

Dr Art Hister – Weight and Genes

Bad news for those of you who swear you can’t lose weight because of your genes: you’re probably wrong.

Lots of people swear that no matter what they do, they can’t lose weight, even if they “don’t eat more than a mouse eats, honest”, even if they “exercise till I can’t stand it any longer”.

But the brutal truth is that even though there are a few people out there who indeed cannot lose weight easily, most of us can, and when we don’t lose weight on a diet or from exercise, it’s very likely because we are eating too much or not working out enough, or more often than not, both of those combined.

And if you believe the data from a study published in PLoS Medicine, even most obese people who are genetically prone to becoming massively overweight can nonetheless overcome their genetic predisposition and still lose a significant amount of weight.

In this study, even in obese people who had inherited “17 variants” of genes leading to obesity (in other words, the dice were really loaded against these folks staying slim), those who did the most exercise tended to weigh much less than those who were sedentary, and some were even able to maintain normal weights by doing enough exercise.

Bottom line: if you want your bottom not to grow too large, do more, eat less.

Sorry, but I just report em as I see em.

Lens Filters: Finding the Right Wavelength

Photography is the art of capturing light. The simplest ways to control the amount of light are right on your mode dial: adjusting shutter speed and aperture size. To modulate the quality of light, a filter is a straightforward, relatively inexpensive way to add drama to your images.

What is light?

To understand how filters change your image, we must go back to basics. Visible light moves in waves of electromagnetic radiation, similar to waves in the water. These waves have three properties that are particularly important to the photographer:

  • Waves have amplitude: the larger the wave, the brighter the light.
  • Waves have frequency that determines the colour of the light: faster waves appear as blue and violet while slower waves appear red and orange.
  • Waves have direction: we refer to this as polarization.

Each type of lens filter changes a property of light. Some block out a portion of all light, reducing the amplitude of the waves. Some block out certain frequencies, which changes the colour composition of the image. Some polarize the light, blocking out waves that are moving in certain directions. Each type of filter produces a unique effect that can transform the final image into a dramatic, professional-looking photograph.

Neutral Density Filters: Controlling the light

Neutral density filters reduce the amount of light passing through the camera lens without changing the colour composition. They are especially useful in bright light conditions to help prevent overexposure. Professional photographers often use neutral density filters to manipulate other camera settings for dramatic effects. For instance, a neutral density filter can allow for a wider aperture setting, which lets the photographer emphasize the subject while the foreground and background are softly out of focus. The photographer could also slow the shutter speed down and, with a tripod, capture the blur of motion while the landscape remains still and sharp.

Graduated Filter: Balancing light for dramatic landscapes

Many scenes, particularly those outdoors, have an unbalanced light intensity: the sky is bright, but the foreground appears dark. A graduated filter blocks out more light waves on one side of the lens, gradually allowing more light toward the other side. Imagine a bright sky with a darker foreground—to properly expose the sky, the foreground will be too dark, but if you expose for the foreground, you overexpose the sky. By positioning the filter with the stronger side up, you can capture more sky detail without underexposing the foreground. The graduated filter, in effect, allows you to manipulate the amount of light in different zones of the photograph.

UV Filter: Blocking out the haze

Light waves can move at different frequencies, some slowly, others fast. These frequencies appear as different colours: at one end of the spectrum are the slow red waves and at the other, quick violet waves. Moving even faster than violet light waves are ultraviolet waves (UV light), virtually invisible to the human eye.

Unlike the human eye, cameras are sensitive to UV light. Think of one of your sunny day landscape shots: when you took the picture, you saw a crystal clear, almost limitless view. The photograph turned out hazy and bluish. This is ultraviolet light, which often shows up on images as a bluish cast in shots from high altitudes, long distances, and over water. UV filters block out these waves, reducing excessive blue, and increasing colour intensity and image clarity.

Sky filter: Colour correction

A sky filter is a type of UV filter with a pink tint for added warmth. As with a UV filter, the sky filter is especially helpful when shooting outdoors, blocking out UV haze for better image clarity. The added tint helps with colour balance, especially skin tones.

Polarizing filters

In bright situations, strong light waves reflect off surfaces, sending waves in all sorts of directions. In photographs, this appears as a whitish glare. Polarizers block out these errant wavelengths: colours appear deeper, blue skies are deeper and more dramatic. This filter also removes glare from non-metallic surfaces, such as windows and water.

Protection and Peace of Mind

UV, sky, and polarizing filters can significantly improve the quality of your photographs, but there is an important side benefit. The filters screw on over your lens, protecting the surface from scratches. Since most filters are a fraction of the cost of a lens, a filter helps protect your photography investment.

For those who want to protect their lens without the added filtering properties, clear lens protectors are also available.

To learn more about lens filters and how they can transform your photographs, bring your camera into the London Drugs Camera Department. Our camera specialists can help you find the right filter for your camera.

Bright Lights, Better Photos

External Flashes for More Beautiful Indoor Pictures
Indoor photography presents a challenge for every photographer, from the novice to the pro. There is simply not enough ambient light in most indoor shots to take a properly exposed photograph. Your camera senses the low light and turns on the built-in flash. This burst of bright light illuminates the subject within a certain distance, allowing a proper exposure.

Dr Art Hister – Do You Even Know if You’re Overweight?

At least one of the reasons we are getting so much fatter on average is that we’re so surrounded by people who are overweight that we’ve lost the sense of what a normal weight should be.

At least that seems to be the case in the US, and I am sure it’s not much different up here.

A recent Harris Interactive/Health Day survey asked a representative group of American adults how much they weighed and how tall they were. The respondents were then asked whether they thought, by BMI status, if they were normal weight or overweight.

A substantial number of the survey takers – 30% – who were overweight by BMI criteria (a BMI over 25) replied that they felt they were normal weight, while 70% of those who were obese thought they were “merely overweight”.

BMI is not a perfect measure of weight. For example, since muscle weighs a lot, a very muscular person can have a high BMI but be normal weight.

That said, most of us are not too muscular (some of us – me, for example – aren’t even slightly muscular) and so for us, BMI is a pretty good measuring rod for what our weight should be.
Most experts say that you should be aiming for between 20 and 25, although I am a lot more liberal than that, so I figure that if you’re working out or just being quite active, you can allow yourself a few extra pounds without worrying about it (never mind “allowing” yourself; how about “accepting” instead because honestly, how do you keep those (few?) extra pounds off anyway as you get older, eh?)
