How is skin affected by the sun?

Your skin is the largest organ in your body. It has two layers called the Epidermis and below that is the Dermis. The two main reasons we have skin is it protects us and controls our body temperature.

The sun's rays contain a variety of different forms of radiation. These are visible light, infrared and ultraviolet rays. One type of UV ray called UVB can harm the DNA in epidermal cells and can cause skin cancer.

Fun Facts:

Getting sun burned just once every two years can triple your chance of getting melanoma skin cancer.

Melanoma is the deadliest form of skin cancer by 75%.

Hey Sarah, 

Cool topic! The skin is certainly one of the most integral components for preventing disease and infection from entering the body and it is a very large organ. It can account for up to 15% of an average adult's body weight and could cover 2 meters on average. Its also crazy to think that skin replaces itself every month! Also great point on how getting burned can can increase risk of skin cancer. Sunscreen is more for preventing harmful UV rays than for preventing a tan though many people think they don't need sunscreen. 

I'm looking forward to seeing some future research!

hey Sarah,

I agree that the  skin is the largest organ in the human body but i would urge you to state both the positive and the negative effects of the sun on our skin since  on my side I think that the sun has more positive than negative effects on our skin such as we get vitamin D from the sun and it has thousands of functions on our bodies.the link  below may be of importance in creating your next post

Good luck!

Thank you for your feedback and the link! I agree that there are many good effects from the sun as bad. I will be sure to write a post on the positive effects of the sun on skin. Thanks again,

 Hi Sarah! 

 This is some really cool research! I like how you mentioned different parts of the skin and the purpose. 

 I also find it interesting how you connected the sun to skin. What made you want to look into that specifically?

 If you want suggestions on where you could go from here, it would be cool to look more at ways of treating skin cancer. Another idea is that you could look into other characteristics of skin and what it's made up of. 

  Good luck with your research! I look forward to seeing more. 

Hey Sarah,

It's really cool to think about the many different ways the sun can impact our bodies, not just our skin. If we are heavily exposed to the harmful rays of the sun, then our skin starts to react in unsightly ways to warn us to get back into the shade. But a healthy amount of sun can do a world of wonder for us, particularly in terms of our emotions. They say the sun makes us smile, and it's very true! The vitamin D our skin absorbs from the sun contributes to a balanced amount of serotonin in our bodies. Serotonin is the hormone responsible for regulating moods. If we don't get the vitamin D we need, our serotonin levels drops and we start feeling a bit gloomy. Now this doesn't impact everybody in the same way, but it sure does have its effects on most of us.

It would be super cool to look into some of the ways our skin can absorb nutrients and vitamins and what exactly those vitamins are. The skin is a really cool organ, so there's a lot to look into!

Great work!

Hello!

Thanks so much for the feedback! I will try to look into some different ways of curing skin cancer. 

Thanks again,
