Smoking is definitely worse. Both sunbeds and smoking are harmful to your health if you do them in excess. Sunbeds using UVB producing lamps can increase your risk of skin cancer, while smoking can increase your risk of lung cancer. So, it’s important to use sunbeds safely and in moderation just the same as you should only smoke cigarettes in moderation too. However, it’s much easier to become addicted to cigarettes than it is to tanning (although it is possible to be addicted to tanning, too). Tanning salons in the U.K. that adhere to industry guidelines will only use safe 0.3 bulbs that are not associated to the risk of skin cancer.
