QUOTE FOR THE WEEKEND:

“Gender is an extremely salient risk factor, even controlling for differences in the type of events that are experienced by men compared to women. A consistent finding has been that the preva­lence of PTSD is almost twice as high in women as it is in men.  Lower levels of education and income, and being divorced or widowed are risk factors PTSD.”

QUOTE FOR FRIDAY:

““Thirty years ago this month, President Ronald Reagan issued a presidential proclamation designating the last week of June as “Helen Keller Deaf-Blind Awareness Week.” Every year since, the Helen Keller National Center for Deaf-Blind Youths & Adults (HKNC) commemorates the week with a national advocacy campaign in recognition of the achievements and capabilities of people who are deaf-blind.”

QUOTE FOR THURSDAY:

“If a child is born totally blind, how will that limitation affect her con­nection with those around her? The literature estimates that 75%of most people’s learning comes through vision (Smith & Cote, 1982). A deaf infant with nor­mal vision will not have the same trouble developing early bonds with his caregivers as an infant who is blind because, as we have seen,the eyes are a main avenue for these early bonds.”

Summer ailment flare-ups due to hot weather.

 

Hot weather has its hazards, from rip tides to shark scares to sunburn and close encounters with poisonous plants. Simply step outside on a hot summer evening and you’re bound to become instant mosquito bait.

There are less well-known summer health hazards you should keep in mind. Hazards that affect your body from within. Here are some summer health ailments that get worse as the temperatures rise.

1. Kidney Stones

Climate change is affecting not only our planet, it’s taking a toll on our health. Case in point: A University of Texas study has found that the incidence of kidney stones will increase in step with rising record temperatures. Researchers predict a huge increase in kidney stones by 2050. To help prevent kidney stones, which are made up of mineral and acid salts, the Mayo Clinic advises staying well-hydrated (which also will help protect you from heat stroke) when the weather’s sultry. It’s important to keep levels of protein, sugar and sodium (especially) in your diet low. Note that if you live in a warm part of the country or tend to sweat a lot, you may be at higher risk of kidney stones.

2. Migraine headaches

As the temperature rises, so does the risk of migraine for someone who’s prone to them. A study of more than 7,000 emergency room patients who came in for migraine symptoms during a seven-and-a-half-year period revealed that for every 9 degree F bump in temperature, migraine cases increased. To head off migraines in summer, the Cleveland Clinic advises staying hydrated (rely on water and other non-caffeinated beverages) with eating regular meals no matter how busy you are (your bike partner can wait) and steering clear of common migraine triggers if they affect you. Some you’re likely to encounter in summer are like hot dogs, pickles, beer and certain cheeses.

3. Rosacea

Sun exposure, elevated temperatures and wind — hallmarks of summer weather — can bring rosacea flare-ups. If you have rosacea, a skin condition that causes redness, bumps, eye irritation and thickening of skin around the face and other parts of the body, fend off flare-ups!

Tips from the National Rosacea Society:

  • Apply sunscreen at least 30 minutes before heading out and reapply every couple of hours.
  • If you can, stay out of the sun when it’s at its strongest (between 10 a.m. – 4 p.m.)Head outside early in the morning or late in the afternoon to stay cool and avoid the heat that may trigger a flare-up
  • Add a wide-brimmed hat and a good pair of shades protect your face and eyes from UV rays.

4. Heart attack

Winter may be peak season for heart attacks, but summer heat also can take a toll on people with cardiovascular disease or who are at risk for it, according to the American Association of Heart Failure Nurses (AAHFN). That’s because high temperatures increase heart rate and lower blood pressure. Folks with weak hearts may not be able to pump enough blood to cool their bodies and can quickly become overheated. If you have heart problems, the AAHFN recommends you stay inside on blistering days, make sure you drink enough fluids (and back off of caffeine and alcohol) to keep you hydrated and have someone on speed dial who can get to you quickly if you need help.

5. Asthma

Summer whims can spell trouble for people with asthma. When air temperatures change suddenly — as when the thermometer plummets just before a thunderstorm — it can bring on asthma symptoms, according to the American Lung Association. Asthma sufferers also may have trouble breathing in outdoor air pollution as well as when ozone levels are high, which occurs more often in the summer. If you have asthma, your best protection is prevention: Keep a check on daily air quality and, if you live in a city, heed the smog warnings that often occur on steamy days. If the weather outside seems frightful, stay indoors as much as possible.

6.  Summer Ozone Dangers

As the weather heats up during the summer months, ground-level ozone pollution increases as pollutants react to heat and sunlight. So if going on vacation from non ozone levels to danger ozone areas be careful.  Ozone levels often increase with summer wildfires, further worsening the air quality and ozone-related breathing issues.  Areas consider high in danger ozone areas are Bishop, CA, Great Basin Air District, CA, Bishop Paiute Tribe, CA, Southern Ute Indian Reservation, CO, Tallahassee, FL

Exposure to ground-level ozone can exacerbate chronic respiratory symptoms, reduce lung capacity and be a trigger for asthma attacks. Other conditions affected by high ozone levels in the summertime include COPD, heart disease and diabetes.

7. Eczema Flare Ups

Yes those of us suffering from eczema understand very well that winter months can be the toughest time of year – dry air, cold temperature, low humidity making skin susceptible to eczema breakouts and flares.  Remember that also here’s a plenty of sunshine, high humidity and warm temperature. All weather conditions that is ideal for eczema. 

Hot weather makes everyone sweat more. Sweating is our natural defense mechanism to control the body’s temperature. Sweat consists of mostly water. As water evaporates from the skin surface, it provides a natural cooling sensation and also lowers the body temperature.  In addition to water, there are trace amounts of sodium, potassium, calcium, magnesium, lactic acid, urea, copper, zinc, nickel, iron, chromium and lead in the sweat. Many of these chemicals, if presented at a high enough concentration, may be irritating to the skin.

Hot weather worsens the itch, blockage of sweat glands, and other bad summer exposures are chlorine it can wreak havoc on your skin and hair. For one thing, chlorinated water can definitely dry out your skin.  Also, to prevent skin cancer, premature aging, and sunburn, it is a good idea to use sunscreens.

 

 

QUOTE FOR TUESDAY:

“Sinusitis usually occurs after a viral upper respiratory infection or cold and includes thick, discolored nasal mucus, decreased sense of smell, and pain in one cheek or upper teeth. Headaches due to sinus disease often last days or longer and migraine headaches most commonly last hours to a day or two.  Headaches due to sinus disease often last days or longer and migraine headaches most commonly last hours to a day or two.”

Sinusitis and Headaches in hot weather!

During summer and on those very hot days it is marvellous to go to the beach, relax at the pool side, have a barbeque or even picnic out with friends and family but then you may notice that your nose starts to run, you suddenly develop a headache or you feel stuffy.

Sinuses, which are paired air spaces connected to your nose, is lined with very delicate skin called the mucus membrane. The mucus membrane may then become inflamed by many things like bacteria, colds and flu’s, allergies or even a fungus invasion.  We start to feel all those dreadful symptoms when these sinus spaces are blocked, causing mucus build up and pressure.

The most common culprit of summer sinus problems is allergies and hay fever. We don’t hear enough about how pet hair, pollen, dander, dust and dust mites and even milk or how certain food allergies cause sinus problems. But what else about those hot days cause our sinuses to go ballistic?

One often hears about sudden extreme temperature changes causing increased sinus pain and a stuffy or runny nose, but how?

There are millions of tiny hair like structures called cilia that make up the mucus membrane, which lines your nose and sinuses. These cilia work together as a broom, helping to get rid of stagnant mucus that may block the sinuses. Your mucus membranes prefer a moist warm environment as opposed to it being very cold or very hot.

On hot summer days the air is very dry causing the mucus in your nose to become thick and sticky. This makes it difficult for the cilia to move or “sweep” the excess mucus out. This thick mucus then blocks the sinuses. When mucus flow is interrupted or blocked, it often becomes hard in nature and causes pressure and congestion. The pressure and the congestion then cause you to experience pain, stuffiness and headaches.

Know the difference:

Viral sinus infections are the most common type of sinusitis. Viruses that cause the common cold are usually the reason for the sinus infection. The symptoms of a viral sinus infection typically last up to seven to ten days.  The first few days your symptoms will worsen and after about the fifth day you may start to see improvement. These types of sinus infections generally go away on their own with rest and vitamin C. The symptoms you may experience while having a viral sinus infection are headaches, congestion, low fever, nasal discharge, and trouble sleeping. If your cold is lingering around and does not runs its course naturally you may actually have a bacterial sinus infection. Learn the signs that indicate your cold may be a bacterial sinus infection.  Viral sinus infections do not require antibiotics. When you experience any type of sinus infection it will more than likely be a viral sinus infection.

Bacterial sinus infections are less common than viral sinus infections. It may be difficult to tell the difference between bacterial and viral sinus infections because they share common symptoms.

In some cases a viral sinus infection can develop into a bacterial sinus infections. This occurs when bacteria multiplies in fluid-filled sinus pockets. Bacterial sinus infections may also resolve on their own but may require antibiotics to fight off the bacteria. Signs that your viral sinus infection has increased to a bacterial sinus infection are a noticeable increase in the severity of symptoms or failure to get better after seven to ten days. Some common symptoms of bacterial sinusitis are worsening congestion,  more severe facial pain, and thickening or increase of nasal discharge. Bacterial sinus infections can also return shortly after your symptoms have healed, making you think, why do I keep getting sinus infections? If your nasal discharge or mucus is thick, dark, and/or greenish-yellowish, you may have converted to a bacterial sinus infection. Evaluation by your doctor can determine whether or not you have a bacterial or viral sinus infection. If your symptoms show no sign of improvement after ten days it is safe to say you have developed a bacterial sinus infection.

Summer Sinus Health Tips

  1. Try to Avoid Pollen: Pollen levels are usually highest in the morning so try and stay indoors. Use a HEPA filter, reduce carpeting, and try and vacuum the interior of your home often. Keep your windows closed during especially bad sinus days.

  2. Make sure you always have a Saline Nasal Spray: One of the most helpful precautions to ward off colds are to keep your nasal passages moist. 

  3. Consider Nasal Irrigation: Cleaning out the nasal passages helps remove bacteria, pollutants and other irritants that can lead to sinus pain and infection. The simplest way is to lean over a sink and use a neti pot to run warm saline into and out of your nasal cavity. You can also use a squeeze bottle which is specifically designed to irrigate the nasal passages. 

  4. Avoid nasal irritants: The membranes that line the nostrils and sinuses are very sensitive and can be damaged from an array of irritants. Two common irritants are tobacco smoke and chlorine. Additional items to avoid are exhaust, mold, and smoke of any kind. 

  5. Be prepared when flying: The dry air and poor interior conditions in an airplane cabin are a perfect area for germs and bacteria to collect. Drinking lots of water and sporadically spraying inside your nose with a saline solution can help fight against these conditions.

 

QUOTE FOR MONDAY:

“Nasal sinus disease, or sinusitis, affects approximately 33 million people and accounts for more than $5.8 billion in healthcare costs annually, according to a release from Monell. Most of the time, the condition is caused by infection or allergy, which, in turn, causes sinus tissues to swell.”

NBC NEWS

It’s that time of the season again, Sinuses!

The sinus cavities include:

• The maxillary sinuses (the largest), in the cheekbones.
• The frontal sinuses, in the low-center of the forehead.
• The ethmoid sinuses, between the eyes, at the nasal bridge.
• The sphenoid sinuses, in bones behind the nasal cavity.

The sinuses are lined with soft, pink tissue called mucosa. Normally, the sinuses are empty except for a thin layer of mucus.

The inside of the nose has ridges called turbinates. Normally these structures help humidify and filter air. The nose is divided in the center by a thin wall, called the septum. Most of the sinuses drain into the nose through a small channel or drainage pathway called the middle meatus.

The purpose of the sinuses is unclear. One theory is that sinuses help humidify the air we breathe in; another is that they enhance our voices.

There are millions of bacteria in our noses, and most of the time, they’re harmless. Even when a few creep into the sinuses, they don’t cause trouble, as long as they keep draining into the nose along with mucus. But if sinus drainage is blocked, glands in the sinuses continue to produce mucus, and the resulting pool of backed-up mucus provides what Dr. Metson calls “the perfect culture medium.” The bacteria grow out of control, causing infection, and the immune system kicks off an inflammatory response. The result: swelling, which causes headache and facial pain; mucus buildup, which produces congestion; and an influx of white blood cells to fight the bacteria, which thickens the mucus and may tint it yellow or green. Other symptoms include loss of smell or taste, cough, bad breath, fever, toothache, and fullness in the ears.Sinus blockage can have a variety of environmental, anatomical, and genetic causes, but the main culprit is swelling of the nasal passages produced by the common cold or allergies. More serious sinusitis can result from structural problems, such as a deviated septum (a crook in the partition that separates the right from left nasal cavities) or nasal polyps (small, grapelike growths in the lining of the sinus cavity).

“As a person gets older, changes occur in all parts of the body, including the brain.  Certain parts of the brain shrink, especially those important to learning and other complex mental activities.”

NIH National Institute on Aging

How aging affects the human brain and our thinking.

 

  

The brain controls many aspects of thinking—remembering, planning and organizing, making decisions, and much more. These cognitive abilities affect how well we do everyday tasks and whether we can live independently.

Some changes in thinking are common as people get older. For example, older adults may have:

  • Increased difficulty finding words and recalling names
  • More problems with multi-tasking
  • Mild decreases in the ability to pay attention

Aging may also bring positive cognitive changes. People often have more knowledge and insight from a lifetime of experiences. Research shows that older adults can still:

  • Learn new things
  • Create new memories
  • Improve vocabulary and language skills

The Older, Healthy Brain

As a person gets older, changes occur in all parts of the body, including the brain.

  • Certain parts of the brain shrink, especially those important to learning and other complex mental activities.
  • In certain brain regions, communication between neurons (nerve cells) can be reduced.
  • Blood flow in the brain may also decrease.
  • Inflammation, which occurs when the body responds to an injury or disease, may increase.

These changes in the brain can affect mental function, even in healthy older people. For example, some older adults find that they don’t do as well as younger people on complex memory or learning tests. Given enough time, though, they can do as well. There is growing evidence that the brain remains “plastic”—able to adapt to new challenges and tasks—as people age.

It is not clear why some people think well as they get older while others do not. One possible reason is “cognitive reserve,” the brain’s ability to work well even when some part of it is disrupted. People with more education seem to have more cognitive reserve than others.

Some brain changes, like those associated with Alzheimer’s disease, are NOT a normal part of aging. Talk with your healthcare provider if you are concerned.

Brain Regions

The brain is complex and has many specialized parts. For example, the two halves of the brain, called cerebral hemispheres, are responsible for intelligence.

The cerebral hemispheres have an outer layer called the cerebral cortex. This region, the brain’s “gray matter,” is where the brain processes sensory information, such as what we see and hear. The cerebral cortex also controls movement and regulates functions such as thinking, learning, and remembering.

How Brain Cells Work

The healthy human brain contains many different types of cells. Neurons are nerve cells that process and send information throughout the brain, and from the brain to the muscles and organs of the body.

The ability of neurons to function and survive depends on three important processes:

  • Communication. When a neuron receives signals from other neurons, it generates an electrical charge. This charge travels to the synapse, a tiny gap where chemicals called neurotransmitters are released and move across to another neuron.
  • Metabolism. This process involves all chemical reactions that take place in a cell to support its survival and function. These reactions require oxygen and glucose, which are carried in blood flowing through the brain.
  • Repair, remodeling, and regeneration. Neurons live a long time—more than 100 years in humans. As a result, they must constantly maintain and repair themselves. In addition, some brain regions continue to make new neurons.

Other types of brain cells, called glial cells, play critical roles in supporting neurons. In addition, the brain has an enormous network of blood vessels. Although the brain is only 2 percent of the body’s weight, it receives 20 percent of the body’s blood supply.
