Irrational thoughts are distorted, often negative beliefs that are not solidly based in reality, but nevertheless influence our emotions and behaviour. They can take the form of catastrophising ("Everything is going to collapse"), black-and-white thinking ("I am a total failure") or over-generalising ("I always fail"). Everyone experiences such thoughts from time to time, but when they become a habit, they can lead to anxiety, stress, lowered self-esteem and even health problems such as depression. In today's world, where social pressures, the media and the fast pace of life can reinforce these distortions, the ability to deal with irrational thoughts becomes crucial to mental health.
