Thursday Is Looking Hot

After the hot weeke we had last week I know most of you would like to see the heat take a much needed break. Not happening!

One of the big positives that we are looking at right now is the fact that our next hot streak will only last around a day or two. It will be plenty hot though! By the time that Friday arrives I think we'll see some pretty high humidity levels and enough heat to make it rather uncomfortable.

Here's what the RPM is spitting out.



Current Temps:

When the humidity is factored into this we'll see feels like temps somewhere around 100. Not a great day to be out and about! Especially, if you aren't following proper advice.

The SPF 15 is the minimum and that's only if you are going outside for a shot amount of time. I personally recommend going with a longer formula. Speaking of SPF... I found this very useful.

SPF Sunscreen Meaning Explained
First and foremost, comes the full form of the term 'SPF'. Basically, SPF is an acronym for 'Sun Protection Factor'. So that is one question answered (although I'm guessing you already knew the answer to that one). Now, for those of you who are not very knowledgeable regarding the necessity or the purpose of sunscreens, here is the answer. Prolonged direct exposure to the sun almost always results in sunburns, i.e. reddening of the skin. Applying sunscreen to exposed skin areas protects them from the sun's harmful UV rays, and also lessens the chances of developing skin cancer and other skin problems. Now that we know about the SPF sunscreen meaning and its uses, we will tackle the concept of SPF sunscreen numbers or SPF sun protection levels. When a certain sunblock lotion is advertised as being SPF sun block 30, what does that imply? What does SPF sunscreen 'XYZ' mean? Well, the answer lies in the following paragraph.

SPF Sunscreen Levels Explained
To put it in simple words, the SPF level of a sunscreen lotion is an indication of how long the sunscreen will remain effective, not how strong the sunscreen is. Consider the following example.

You have two SPF sun screen lotions, one being an SPF 15 and the other being an SPF 30. Now, let me clear a common misconception that people have. The SPF numbers, by themselves, do not indicate the amount of time that the sunscreen lotion will remain effective. Rather, the SPF numbers need to be multiplied by another factor, or in mathematical terms, a constant. What is that 'constant', you may ask. Well, that constant is nothing but the amount of time that it takes, for your skin to show signs of reddening or sunburn, when left uncovered and exposed directly to the sun.

What that means is, if 15 minutes is what it takes for your skin to redden when exposed to direct sunlight, then 15 is the constant in your case. Now, how do you calculate the amount of time that the sunblock lotion will remain effective? Well, you simply multiply the SPF level of the sunblock lotion with your individual constant. So, if 15 is your constant and you have an SPF 15 sunscreen lotion, then you have, 15 x 15 = 225. Those are the number of minutes for which the sunscreen lotion will continue to remain effective after you apply it.

What is obvious in this case, is that the constant will not remain constant for everyone (unintentional paradox!). For you, it could be 15 minutes, for your partner, it could be 10, whereas for someone else, 5 minutes of direct sun exposure would be all it takes for his skin to redden. What this implies is that, the 'safe period' (in the context of direct sun exposure) is not the same for every person, even if they use the same sunblock lotion. For instance, consider a situation wherein both you and your partner head to the beach for 2 hours of sunbathing, and you both apply an SPF 15 sunscreen. Now if your constant is 10 and his is 5, what it means is that the SPF 15 sunscreen will protect you for 150 minutes, whereas it will protect your partner for only 75! In this case, the only other option your partner has, is to reapply the sunscreen after an hour, or use a sunscreen with a higher SPF level, such as an SPF 30. More on skin care.

SPF Sunscreen Selection Tips
Typically, sunscreens with SPF levels in ranges of 30 and 50 are recommended for outdoor activities like sunbathing, sea bathing, swimming, etc. Sweat and water often result in the sunscreen lotion wearing off your body, so reapplying it at regular intervals is very important in such situations. Also, look for sunscreens containing zinc oxide and titanium dioxide. They provide excellent protection. You can read more on zinc oxide sunblock.

I hope that you are now clear in your mind, regarding SPF sunscreen meaning, and the significance of SPF sunscreen numbers. Remember, wearing sun protective clothing, in addition to applying sunblock lotion, is also important for ensuring proper protection from the sun's rays.

Enough about the heat... By late Friday we'll be staring at a cold front. It will bring showers & storms. At this point all of the organized severe weather looks to stay north of the area. I won't completely believe that until it happens. Stay alert going into the weekend. I'll have more on all of this as the information becomes available.
