Dry skin gets irritated more easily and that’s why it often causes itching. Especially in winter, or other times when heating or air-conditioning is on. Or even when your skin comes in contact with certain kinds of fabric.
Itching can get to be very bothersome. It can even cause you to be more irritable or to lose sleep. The first step you can take before it gets to this stage is quite simple: moisturise, moisturise, moisturise!
It’s quite likely that with this simple action, the itching will disappear. If not, it’s best to consult your dermatologist or a doctor.
