CDC INFOGRAPHICS: ‘HEAT STROKE & HEAT EXHAUSTION’

COMMENTARY:

THERMOREGULATION, preservation of the normal body temperature, is well developed in humans, and monitoring the body temperature has been useful since the development of thermometers.

Indirect measurement by Infrared detectors is being widely used today to detect FEVER as a sign of Covid in gatherings such as schools. Reactive increase of body temperature in a cool environment is a body defense mechanism that I have discussed earlier. Contrary to general practice, Fever, in my opinion, should be left untreated unless excessive, such as above 103 degrees F., or even 104 degrees.

Excessive environmental temperature, such as in a closed car, Jacuzzi, or heat wave can defeat the body’s ability to defend the normal temperature. Children, with their high body surface to mass ratio, are particularly at risk, as periodic newspaper articles testify. HEAT STROKE is the most serious of heat-related illnesses, leading to high and increasing body temperature, mental symptoms, even convulsions, and is a MEDICAL EMERGENCY.

The treatment is to call 911, and to lower the body temperature by removing insulating clothing, and immersing in cold water. There are a variety of other conditions based on excessive exertion, water or salt loss.

These include HEAT EXHAUSTION. Older Workers are particularly susceptible, and medical clinic attention may be needed for fluid and electrolyte replacement. MUSCLE CRAMPS and even damage( Rhabdomyolysis), FAINTING (this has been discussed before) and Heat Rash can result from too hot an environment. Furry Animals Pant instinctively to get their highly vascular Tongue to “air condition” their bodies. Humans should dress and exercise appropriately when the environment requires it.

NUTRITION INFOGRAPHIC: “GOOD AND BAD FATS”

COMMENTARY:

Water, the miracle molecule, proteins and fats are the very essence of life. Water does not dissolve fat, allowing for the cell membranes, and the compartmentalization of metabolic activity that allows life to happen.

FAT IS ESSENTIAL TO LIFE. Alas, all fats are not equally beneficial to nutrition, as the article stresses. Trans-fats, partially hydrogenated fatty acids produced mainly by industry, are the worst, acting to stimulate cholesterol synthesis, produce inflammation and damage the endoplasmic reticulum.

Their use has been banned in most countries. Saturated fat has been widely condemned, is not as good as the mono- and polyunsaturated fats, but not as bad as trans-fats. Some of life’s most delicious foods, such as cheeses, contain saturated fats, but it is best to keep down their consumption.

Remember that the first bite of something savory tastes the best; prevent habit from shoveling it down. Unsaturated fats are found in oily fish, which should be part of your diet.

Vegetables such as nuts, seeds, olives, and avocados are sources of “good fat” and should comprise 10-15% of your calories. Fats, compared to carbohydrates, contribute almost twice as many calories to your diet on a weight basis, and it’s easy to get carried away.

Total calories must be kept under control. STAY HEALTHY!
