How To Protect Yourself From Harmful UVA & UVB

Sun Protection



Summer is finally here! If you don’t have a proper cooling device. I suggest you get one soon. 

 

The average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880, according to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies.



The record for global temperature represents an average over the entire surface of the earth. 

The temperatures that we experience locally  can fluctuate significantly due to predictable cyclical events  and unpredictable wind and precipitation patterns. 

Global temperature mainly depends on how much energy the planet receives from the Sun and how much it radiates back into space.

The amount of energy radiated by the Earth depends significantly on the chemical composition of the atmosphere, particularly the amount of heat-trapping greenhouse gases.

A one-degree global change is significant because it takes a vast amount of heat to warm all the oceans, atmosphere, and land by that much. 

 

Warming is greater over land than over the oceans because water is slower to absorb and release heat (thermal inertia). Warming may also differ substantially within specific land masses and ocean basins. 

 

Experts point to rising sea levels, record-breaking temperatures across the globe, declining air quality and erratic weather patterns as different manifestations of climate change. 

Recently, the medical community highlighted the negative effects of an increasingly warm, more heavily polluted environment on human health.

 The fatalities of climate change are generally linked to four  factors:

  • Rising temperatures

  • Declining air quality

  • Extreme weather

  • Vector-borne illnesses

The most common causes of death related to rising temperatures include the following conditions:

Heat stroke:Advanced heat exhaustiion 

Individuals diagnosed with heat stroke usually have a temperature in excess of 104 degrees Fahrenheit. 

In addition to the outside temperature, the symptoms of heat stroke may be exacerbated by high humidity,prescription medication, preexisting medical conditions, or the  consumption of alcohol on a hot day. 

Unlike heat exhaustion, heat stroke requires medical attention;  if left untreated heat stroke can negatively affect the brain, heart, kidneys and muscles.

 

Heat exhaustion:According to The Mayo Clinic, heat exhaustion is characterized by profuse sweating and a rapid pulse or heartbeat. These two symptoms essentially indicate that the body is overheating. 

Other signs of heat exhaustion include dizziness, low blood pressure and muscle cramps. Individuals who suspect they have heat exhaustion should immediately stop whatever they are doing, retreat to a relatively cool location, and consume cool water or electrolyte-filled sports drinks.

 

Cardiovascular disease:According to the National Institute of Environmental Health Science, extreme heat (as well as extreme cold) has been linked to a higher occurence rate of cardiovascular disease and conditions, such as stroke and dysrhythmia. 

Cardiovascular disease is already the deadliest medical condition in the United States, and strokes are listed as the country's third leading cause of death.

 

Kidney disease:Prolonged exposure to excessively hot temperatures can lead to major kidney problems, notes American Family Physician  James L. Glazer, M.D.

Rhabdomyolysis, is  a condition resulting from the breakdown of damaged skeletal muscle.​ Muscle breakdown causes the release of myoglobin into the bloodstream.​  Too much myoglobin in the blood, can cause kidney damage. 

Rhabdomyolysis  usually develops as a  result of heat stroke and  linked to long-term renal disease. The body's ability to regulate water intake may also be affected, which can lead to kidney and/or bladder infections.

 

Aggravated allergies:  The two  major allergens pollen and ragweed  spread during relatively warm months. The EPA notes that spring allergy seasons are occurring earlier each year as a result of increasing temperatures

 

 

SUN PROTECTION

  • Protect your skin.  Limit the amount of direct sunlight you receive between 10:00 a.m. and 4:00 p.m. and wear sunscreen with a protection factor of at least 15.

 

Introducing the SPF-45 from Jencare Skin Farm, which provides broad-spectrum protection against both UVA and UVB rays. It is a physical sunscreen that effectively protects the skin from sun damage.

It is non-comedogenic, oil-free, and sheer. It does not clog the pores and is recommended for daily use. SPF-45 protects from the sun as soon as it is applied to the skin  and may be re-applied every 2-3hrs with exposure.

Sunscreen is even important when flying because rays penetrate airplane windows and you are much closer to the sun. It is vital to any beauty regimen even in the winter. UVA rays are strong all year.

 

 

 

 

It is very important to apply a sun protectant any time you go out in the sun . Especially before going swimming or participating in outdoor sports.

 

Usually on product labels you will come across “SPF”, which means “Sun Protection Factor”, which is the estimated maximum “amount” of UV (Ultra Violet) radiation that the product can protect your skin from.

 

There are two basic types of Ultraviolet Rays that reach the earth’s surface:

 

1. UVB (UVB represents the Type B Ultraviolet ),which is the middle energy between the tanning rays UVA and the intense germicidal UVC.

 

2.  UVA  is the Type A Ultraviolet , which is nearest to visible light that causes tanning and aging of the skin. 

 

UVA rays also play a role in skin cancer formation. In addition, the UVA rays penetrate more deeply into the skin and play a greater role in premature skin aging changes including wrinkle formation (photoaging).

There are approximately 500 times more UVA rays in sunlight than UVB rays.

Therefore, in addition to protecting your skin from the effects of UVB rays, it is also very important to protect from the damaging effects of the more numerous UVA rays.

Traditional chemical sunscreen products have been more successful at blocking UVB rays than UVA rays.

 

UVB rays are responsible for producing sunburn. The UVB rays also play the greatest role in causing skin cancers, including the deadly black mole form of skin cancer (malignant melanoma).

 



 

The main difference between sunscreen and sunblock is determined by  how they protect the skin against harmful UV rays. Sunblock is so named because it literally blocks UV rays by forming a physical shield, while a sunscreen absorbs them.

Sunscreen, on the other hand, is the chemical kind that absorbs the UVA rays it’s usually imperceptible. It also tends to break down after prolonged sun exposure, so you will need to reapply every two or three hours to ensure continued protection.

Sunblocks are specially formulated to protect the skin from burning UVB rays, which is why they are generally thicker than sunscreens. 








 

 



ESSENTIALS OF WATER

  • Drink plenty of water regularly, even if you’re not thirsty. Avoid drinks with alcohol or caffeine in them.

  • Water is essential for the kidneys and other bodily functions.

  • When dehydrated, the skin can become more vulnerable to skin disorders and wrinkling.

  • Drinking water instead of soda can help with weight loss.

Water cushions the brain, spinal cord, and other sensitive tissues

Dehydration can affect brain structure and function.  water is also involved in the production of hormones and neurotransmitters.

Prolonged dehydration can lead to problems with thinking and reasoning.

Water  regulates body temperature

Water that is stored in the middle layers of the skin and appears on the skin's surface as sweat when the body heats up. As it evaporates, it cools the body. 

 

The digestive system is  dependent on water

The bowel needs water to work properly. Dehydration can lead to digestive problems, constipation, and an overly acidic stomach. This increases the risk of heartburn and stomach ulcers.

 

Water is needed by the  airways 

During dehydration, airways become restricted by the body in an effort to minimize water loss. This can make asthma and allergies worse.

 

 

Use wipes to wipe your sweat. Again select one that you are not allergic to.





 

Use an umbrella to shield yourself from the sun.

Wash your face with a refreshing soap as long as you are not allergic to it. Take a bath more frequently in an effort to keep cool.

 

Take shelter under a tree and enjoy the cool breeze while you read a book, use your phone , computer or tablet.

Use a sunshade








SUMMER WARDROBE

 

Straw Hat



Shades or  Cool glasses

 

Wear the right clothing that does not attract heat.







 

Jeans Shorts




Beach Shorts

 

 

A baseball cap

 

 

Sleeveless Casual Backless Sling Dress/Blouse

 








FANS

 

While fans are often used to cool people, they do not actually cool air (electric fans may warm air slightly due to the warming of their motors), but work by evaporative cooling of sweat and increased heat convection into the surrounding air due to the airflow from the fans.

The longevity of the fan, both hand held and electric, proves that individual thermal comfort will continue to be maintained by the airflow of fans, enabling people to consistently keep cool and function in high temperatures.

 

 Consider which fan is most suitable for you. You might want a classic desk fan, a modern slimline fan, or a futurist design. The size of your room will  determine what you choose. 

For a small room or office, you don't need much more than a desk or tower fan. For larger spaces, something more powerful - or even a portable air conditioner - might be your best bet. 

 

 

 Energy efficiency, purchase cost, longer life span, noise levels and air flow, as well as portability around the house and garden are all reasons for continued use and advanced development of the electric fan.

River Vs Beach 

Swimming  or chilling by  the river 

 A River is a natural flowing watercourse, mainly freshwater, flowing towards an ocean, sea, lake or another river. Small rivers are sometimes called a stream, creek, brook, rivulet, and rill

 

Rivers are part of the hydrological cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, and the release of stored water in natural ice and snowpacks (e.g., from glaciers).

 

Swimming or chilling by the river can be a wonderfully refreshing experience. The temperature of the water is usually lower than the water at the beach. 

 

The area is usually more sheltered with trees and rocks, blocking out the sun a bit compared to the beach where you are exposed to direct sunlight. 

 

It is important to take the necessary precautions when swimming at the river. Avoid swimming when it is flooded or unclean as a result of heavy rain and stay away from the white portion of the water. 

 

Watch out for  the current, waves and underwater obstructions, try not to get carried away. Remember to enter unknown or shallow water feetfirst.
