As children, most of us heard lots of health advice. Unfortunately, some of
it, however well-intentioned, was medically incorrect. See if you've ever heard
- or believed - any of these common summer health myths.
"Wait a half hour after eating before you can safely go swimming." This one seemed almost universally
accepted when I was a child and is still believed today. The myth involves the
possibility of suffering severe muscle cramping and drowning from swimming on
a full stomach. While it's true that the digestive process does divert the
circulation of the blood toward the
gut and to a certain extent, away from the muscles, the fact is that an
episode of drowning caused by swimming on a full stomach has never been
documented. Neither the American Academy of Pediatrics nor the American Red Cross makes any specific recommendations
about waiting any amount of time after eating before taking a swim. There's a
theoretical possibility that one could develop a cramp while swimming with a
full stomach, but a person swimming in a pool or controlled swimming area
could easily exit the water
if this happens. As with any exercise after eating, swimming right after a
big meal might be uncomfortable, but it won't cause you to drown.
According to the World Health Organization, "Drowning is the process of experiencing respiratory impairment from
submersion/immersion in liquid." The possible outcomes of drowning are
classified as death, morbidity (the development of disability or injury), and no
morbidity.
This relatively simple definition was agreed upon at the 2002 World Congress
of Drowning held in Amsterdam. Prior to that meeting, some definitions and
classifications of drowning were not necessarily well defined, and their
meanings were subject to a variety of interpretations by different countries and
health organizations. While some people still try to sort drowning events into
categories (for example wet vs. dry, primary vs. secondary, fatal vs. non-fatal),
these terms may or may not adequately describe a patient's situation, the
effects of drowning on their body, or the potential outcome.
Drowning is a common cause of death and disability. In 2002 over
400,000 (worldwide) people died from drowning; of the 400,000 deaths, 129,000
were in China. In the
US it is the third most common cause of accidental death, with 3,500 deaths per
year, or 10 per day. Twenty-five percent of the victims are children aged 14 and
younger.
The death rate from drowning does not reflect the potential morbidity
(disability) due to brain injury for those who survive a drowning episode.

Drowning occurs when water comes into contact with the
larynx (voice box).
After an initial gasp, there is an initial voluntary breath holding.
This is
followed by spasm of the larynx and the development of hypoxemia (hypo=low +
ox=oxygen + emia=blood), or decreased levels of oxygen in the bloodstream.
Lack
of oxygen causes aerobic metabolism to stop, and the body becomes acidotic. If
not corrected quickly, the lack of oxygen in combination with too much acid may
lead to problems with the electrical conduction system of the heart (cardiac
arrest) and lack of blood supply to the brain.
As body function declines, the larynx may relax and allow water to enter the
lungs. However, up to 20% of drowning victims have persistent spasm of the
larynx, and no water is aspirated (this was formerly known as
"dry" drowning).
Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
Hypoglycemia is a syndrome caused by low blood sugar. Symptoms of hypoglycemia include palpitations, trembling, intense hunger, sweating, nervousness, and weakness. Consuming lifesavers, table sugar, soda, and juice are good treatment options for hypoglycemia.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Rhabdomyolysis is a rapid deterioration and destruction of skeletal muscle. Some of the causes of rhabdomyolysis include severe burns, muscle trauma, coma, seizures, electrolyte imbalance, medications (statins), viruses, bacteria. Treatment of rhabdomyolysis depends on the cause.
Sudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive): abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol, Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, and heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
Seizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Acute respiratory distress syndrome (ARDS) is a lung condition in which trauma to the lungs leads to inflammation of the lungs, accumulation of fluid in the alveolar air sacs, low blood oxygen, and respiratory distress. Causes of ARDS include: pneumonia, aspiration, severe blow to the chest, sepsis, severe injury with shock, drug overdose, and/or inflamed pancreas. Treatment for ARDS include extra oxygen, and/or medication.
Managing your diabetes is important. The goal of diabetic therapy is to control blood glucose levels and prevent the complications of diabetes. Information about exercise, diet diet, and medication will help you manage your diabetes better. Blood glucose reagent strips, blood glucose meters, urine glucose tests, tests for urinary ketones, continuous glucose sensors, and Hemoglobin A1C testing information is also provided in this article.
Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.
First aid is a complicated subject and it is situation-specific. First aid is the help and medical assistance that someone gives, not only to an injured person, but to a person who is sick. Preparedness is a key element of first aid, like having basic medical emergency kits in your home, car, boat, or RV. Cuts, puncture wounds, sprains, strains, nosebleeds are one type of injury that may require first aid; heart attacks, strokes, seizures, and heat stroke are examples of more critical first aid emergencies.
Natural diasters such as a hurricane can take a toll on family, friends, and neighbors. Both physiological and psychological stresses can be devastating. Learn how to prepare for a hurricane like food storage, safe water, first aid measures, cleaning mold, wearing protective gear, preparing for electrical hazards, avoiding carbon monoxide, avoiding physical injuries and hazardous materials, preventing drowning, reducing the risk of thermal stress, and preventing fatigue related injuries.
Hurricane damage accounts for on average of $5.1 billion in damages per year.
From 2000 to 2010 the National Oceanic and Atmospheric Administration recorded
1,153 deaths due to hurricanes, with the majority occurring in 2005 due to
Hurricane Katrina, a Category 4 storm that hit the Gulf Coast of Louisiana and
Mississippi.
This article provides tips to prepare for an encroaching hurricane (including
how to prepare a hurricane kit) before it hits, and what action to take once the
hurricane or major storm has passed.
What is a hurricane?
A hurricane is an intense low-pressure weather system with winds of 74 or
more miles per hour. It is a type of cyclone that generally forms in the
tropics. These storms are defined by high wind speeds, with accompanying rain,
possible storm surges, flooding and tornadoes.
Hurricanes are categorized according to wind speeds based on t...
