A lukewarm temperature is best to avoid drying out your skin.
It’s so tempting to want to indulge in a nice piping hot shower when it’s blistering cold out. It sounds lovely just thinking about the hot water warming your skin. However, that hot shower could do you more harm than good. Washing your skin with hot water, especially when you have skin prone to dryness and inflammation (conditions like eczema), can make it quite difficult for you to keep your skin moisturised and healthy. If you then combine hot water with a lot of soap, you could be stripping your skin of its natural oils which protect and nourish your skin.
So, reduce the lather, take shorter showers, and use lukewarm water.
Give your skin a chance to bounce back by using gentle natural products to cleanse and moisturise your skin.
Choose cleansers that contain moisturisers to avoid stripping your skin of its natural moisture barrier.
