• UVB are more high-energy rays that cause delayed effects on skin, including spots and an uneven tone.
Interesting Facts to note :
• 7 minutes exposure to mid-noon sun will induce immediate tanning
• UV rays penetrate 30 feet into water
• Pavements can reflect up to 45% of UV rays
• Clothes can allow up to 60% of UV rays to penetrate.
I too spend a considerable amount of time outdoors,shooting for my blog and so I am quite often exposed to the harsh rays of the sun. So I make sure that I use a sunscreen or moisturizer with SPF protection in my daily routine for protection from the UV rays. I make sure I shoot around 7am and wrap up by 10am and consequently avoid direct sun exposure during and around noon as it causes the most amount of damage.
2. Indoor Radiation- I was surprised myself to learn from Pond's that visible light, indoors from our computer screens, cell phones, tablets, office lights, etc. can penetrate deep into the dermis causing skin damage similar to UV damage. Considering the amount of time I spend working on my laptop, not to mention my smartphone addiction -keeping tabs on all my social media accounts, indoor radiation is surely another cause for concern. So I make sure that I keep the brightness levels low on both my laptop and cell phone, to minimize the exposure to visible light.
Other sources of indoor radiation to watch out for include technology gadgets, cooking fumes, chemical odors, and second-hand smoke.
Did you know that 4 days in front of your laptop = 20 minutes in the noon sun and that chronic repetitive exposure to sources of heat (i.e. stove, heated car seat, laptop) may cause skin darkening.
