This is not true. The Earthâs movement around the sun has very little effect on the onset of seasons at either hemisphere. In fact, the Earth is at the Perihelion or closest to the sun around the winter solstice, while the earth is farthest away from the sun or at the Aphelion around the summer solstice.
How long do cold sores last? From the time of the first tingle, a cold sore will take between 7 and 10 days to completely heal - sometimes up to 14 days. Each cold sore goes through several stages before it disappears. In the vast majority of cases, the sore will heal without scarring.
Cold sores â also called fever blisters â are a common viral infection. They are tiny, fluid-filled blisters on and around your lips. These blisters are often grouped together in patches. After the blisters break, a crust forms over the resulting sore. Cold sores usually heal in two to four weeks without leaving a scar. Cold sores spread from person to person by close contact, such as kissing. They're caused by a herpes simplex virus (HSV-1) closely related to the one that causes genital herpes (HSV-2). Both of these viruses can affect your mouth or genitals and can be spread by oral sex. Cold sores are contagious even if you don't see the sores.
