This is definitely wrong, and this misconception brings lethal consequences especially to children. The interior of a car parked in direct sunlight can reach temperatures between 55 ˚C and 78 ˚C when the temperature outside the car is 27 ˚C– 38 ˚C. On a day that is 28 ˚C— even with the windows rolled down 5 centimeter — the inside of a car can reach 43 ˚C within 15 minutes. On a day that is 34 ˚C, the inside of a car can reach 52 ˚C in just 20 minutes! Bear in mind that the body of a child — especially a young child — is less adept at handling heat. This is because they have less capacity to sweat and they have greater exposure to the heat since their bodies have more surface area relative to their volume.

Sweating is NOT always able to sufficiently cool the body. When the humidity and temperature are both high, evaporation is slow. Since evaporation is the cooling process that is needed to cool the skin, a high humidity reduces the potency of cooling from sweat. The sweating process is also reduced if the body is lacking sufficient fluid or the skin is covered with clothing that impedes the evaporation process.

Unfortunately, thirst isn't always a reliable gauge of the body's need for water, especially in children and older adults. A better barometer is the color of your urine: Clear or light-colored urine means you're well hydrated, whereas a dark yellow or amber color usually signals dehydration.

Water doesn't contain any of the essential electrolytes the body needs to replace after vomiting. In children, carbonated beverages, tea, fruit juice, and sports drinks will not correctly replace fluid or electrolytes lost from diarrhea or vomiting. Nor will plain water. The intestines irritated by gastroenteritis do not absorb plain water as well. Instead children should be given oral rehydration solutions. As for adults and adolescents, although they have a larger electrolyte reserve than children, electrolyte imbalance and dehydration may still occur as fluid is lost through vomiting and diarrhea. Initially, adults should eat ice chips and clear, noncaffeinated, nondairy liquids such as fruit juices.

It is very possible to prevent the spread of stomach flu by following these common-sense precautions: wash your hands thoroughly, use separate personal items around your home, and avoid close contact with anyone who has the virus, if possible.

There are three kinds of ultraviolet (UV) rays: UVA, UVB and UVC. UVA rays penetrate the skin fairly deeply, altering our pigmentation to produce a tan. UVB rays are the primary sunburn rays. These rays also damage our skin's DNA and cause photoaging, pigment changes, and carcinomas (cancerous tumors). UVC rays are absorbed by the atmosphere and don't make it to the ground. The SPF on a sunscreen refers to the amount of protection the product offers from UVB rays or sunburns. Many sunscreens, therefore, need to offer protection from both UVA and UVB rays. Broad spectrum means protection against UVA and UVB. Look for an SPF of at least 15 and one of the following ingredients: mexoryl, oxybenzone or avobenzone for UVA protection, or titanium dioxide or zinc oxide (which block both UVA and UVB).

We all know that tanning is unhealthy and can lead to skin cancer and premature aging. But what about tanning booths? Tanning booth companies often say that they are filtering out the so-called "sunburn" UVB rays, but when you go to a tanning booth, you're still exposing your skin to UVA rays, which penetrate deeper into the skin and cause damage that can lead to premature aging and the development of skin cancers.

Even on a cloudy day, UV radiation from the sun reaches the earth's surface. So make sure you use sunscreen every day, and reapply every two hours and after swimming or sweating. Also, don't fall prey to the myth that just because you're wearing makeup with an SPF, you're protected, you would have to put on 14 or 15 times the amount of makeup that a normal person would wear to reach the SPF on the label of powdered makeup. The same thing goes for foundation and liquid makeup. Make sure you use sunscreen in addition to your makeup.

: Butter and oils trap heat and make your sunburn worse. Need something to sooth tender skin? Try aloe. Sunburn treatment starts with prevention. Correctly using sunscreen will help prevent burns. Sunburns are caused by UV radiation rather than heat (ie, we get sunburns on cold, snowy days).
