Eczema tends to be hereditary and typically occurs in conjunction with allergies, including asthma and hay fever. While it is commonly seen in infants, most children have less eczema symptoms after age two. If eczema symptoms continue throughout adolescence and adulthood, the characteristics and severity of symptoms may fluctuate. Controlling stress and anxiety may help improve eczema symptoms, however psychological factors are merely triggers and do not cause eczema. Changes in temperature, as well as exposure to water and environmental irritants and detergents, may trigger eczema symptoms as well.
