Summer Sunscreen Tips

Jun 17, 2016

Chances are you'll be spending some time in the sun this summer. Here's what you need to know about sunscreen and protecting your skin from the sun's short-term and long-term harmful rays as well as the science behind it all.

What does sunscreen do?

Sunscreen shields the skin from the sun's harmful invisible ultraviolet rays. UVA rays are the long-term aging rays. UVB rays are the short-term burning rays. UVC rays burn off before they reach earth's atmosphere. Sunscreen shields your skin from UVA and UVB. It also protects your skin from “free radical damage”, which causes permanent damage to your skin.

I never get sunburned, why should I wear sunscreen?

What you normally see as a sunburn – red skin -- is a reaction to UVB rays alone. It’s impossible to tell how much UVA damage you are getting until years from now. Unfortunately, plenty of long-term skin damage can be done without the red flag of sunburn being raised.

What does the SPF number mean?

SPF number indicates the amount of UVB protection a product offers. According to the Skin Cancer Foundation, here's how it works: “If it takes 20 minutes for your unprotected skin to start turning red, using an SPF 15 sunscreen prevents reddening 15 times longer – about five hours. Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB.

The Skin Cancer Foundation explains further: “another way to look at it is in terms of percentages: SPF 15 filters out approximately 93 percent of all incoming UVB rays. SPF 30 keeps out 97 percent and SPF 50 keeps out 98 percent. They may seem like negligible differences, but if you are light-sensitive, or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.”

What happens if I combine two sunscreen products with different SPF’s?

SPF levels do not increase when two sunscreen products are combined (i.e. wearing a SPF 15 and a SPF 30 does not equal a SPF 45). The amount of protection will equal the highest SPF applied.

How often should you reapply sunscreen?

Apply sunscreen at least 30 minutes before heading out into the sun. Despite what the label says, if you are spending time outdoors, all sunscreens, no matter what the SPF value, must be reapplied every two hours and after swimming or exercise.

Can you get sunburned through your clothes?

All fabrics offer some sun protection. Some clothes carry an Ultraviolet Protection Factor (UPF) value, where UPF ratings range from 15 (good) to 50+ (excellent). People with very fair skin who burn easily and people spending a lot of time on the water or in high elevations can benefit from wearing UPF rated clothes. People with average or darker skin who rarely burn will rarely get sunburned through their clothes. If you will be spending a lot of time in the sun, consider wearing a hat to protect your face and a rash guard to cover more of your body over a swimsuit.

Dear dish it, my friend first met eachother on the first day of kindergarten we sat next to one another and we became close. we were BFF's throughout 1st to 2nd grades. then, the second grade teacher realized there were alot of kids in the class. and same w the 3rd grade teacher. so, we had to have a split class. my friend was in the split. I was not. It all seemed like the teachers were doing somthing... weired. all the girls (well, almost there were only 6 girls on one half) were in the split. and all the boys were in regular . AND YOU KNOW WHAT ELSE WAS WEIRED! :( :( :( :( :( :( :( :( :( all the boy BFF's and the girl BFF's were SPLIT. me and my friend,kids named Nia & Georgia, Isaac& Ethan, and more. it was so sad for all of us.2 months later, I got homschooled. 2 years later im back in public with my 4th grade self. everything had changed. a bunch of people were obsessed w\ a girl my age named kassidy. im neighbors w\ kassidy and she is REALLY cool and nice. but the whole I  [s:sm3/1jw1] kassidy crew got mean. if I asked them to play they would say. "If Kassidy is playing I will" or I would want to be parteners with kassidy on something and they would freak out. anyway jasmine NEVER invited my to anything, and I am trying to be nice to her ( ice cream money, homework help, comfort when sad, ect.) And not to mention I invited her to 3 things!!! on the bright side she came to 2 :thumbsup :thumbsup she also embarassed me by saying that she was moving I freaked out  because I cared about her and I would cry all the time. I even held onto her and said sadly, "PLEASE DON'T GO!!  :sad :sad . later i found out that she was not moving, she was going to CA for a vacation. even the teacher was in on it!! :mad :mad anyways, my parents told me that i should just let go of her. But i am not ready. HELP??? :e :e :e :e :e

When I was a child I wanted glasses SOO bad, cuz I wanted to copy my mom and sister. And also, I thought they looked cool. I wear glasses now. I have had them for 2 years and honestly I don't mind them. Although, this year I am gonna pry get contacts for swimming better and stuff like that. But if you don't need glasses I wouldn't recommend wearing them. They're not bad, but trust me after a while you will pry not like them as much. But hey, that's my opinion. If you want to do it I'm not gonna stop you. Do what makes you happy in the long run. And tell your friends that they are non prescription if you don't need them, but still get some.

I agree I was afraid of that first too. Eventually I just began inviting my friends over and they don't use it/practically obsess over it like I do but they understood why I use kidzworld and not many other forms of social media.

They would put me in trouble for falling in love. They believe I can't date until age 20. Aw, well, my advice for you would be to talk to your parents about it. There's no point trying to sneak around like those films and it is better for your mind if you talk to them about it. It can be super difficult I know but if you and your parents get along really well then you guys can talk about it and make it work. On the other hand, if your parents ban you from falling in love as you put it, then I think it's better just to stay as friends with him.
