Eczema can be triggered by exposure to hot water. Hot water irritates the skin and can make the symptoms of eczema worsen and lead to dry and cracked skin. Instead of taking hot showers or baths use luke warm water when you bathe. This will clean your skin just as well as hot water but is far gentler on the skin and can prevent eczema flair ups. So, switch to warm water bathing and don't forget to apply moisturizer immediately following your bath.
It is important to avoid too much stress if you suffer from eczema. Of course, having the skin condition can cause stress, as can life itself. But, a lot of stress increases flare-ups. If you find yourself getting stressed out, learn how to relax yourself. Yoga and meditation are two great ideas.
