Sun 4U Tanning Beds A lack of vitamin D has been found to be one of the causes of winter depression, autism, and even cancer. Vitamin D is needed for a healthy heart, bones, skin, immunity, and mood. Without enough sunshine, the body cannot naturally produce vitamin D. So how can you be sure to get enough vitamin D? By using our special, safe Home Tanning Beds!
The Sun 4U Home Tanning Beds have three types of light:
● UVA (1) and UVB (2) lights help your body produce the proper amount of vitamin D without harmful effects.
● Infrared light (3) provides relief of muscle pain and stiffness. Its red glow will give a more youthful appearance by reducing wrinkles.
Identify what is scientifically correct and what is scientifically incorrect.
Incorrect: UVA rays cause cancer... they are not good for you. UVB rays cause sunburns and cancer in large amounts.
Correct: A little UVB rays do help you to make Vitamin D.
