#8 Sunburn and Other Sun Damage
We all need vitamin D, and the best source is the sun. However, over-exposure to the sun can do considerable damage. Not only does bad sunburn frequently lead to blistering and peeling skin, but long term it is likely to make the skin less pliable and resilient. When this happens, most people find that bruising occurs more easily, and it is also a lot more noticeable. If you are sunburnt when you bruise, this could also acerbate the bruising as heat causes body tissue to swell, and this can, in turn, cause more internal bleeding.
