Pleasure therapy is all about getting to know yourself – your likes and dislikes – and getting in touch with your body. Studies have shown that self-perception will determine the impact of stress. Scholars argue that if you know yourself well, you will be better able to self-regulate when stressors hit. For example, if I am feeling stressed because of overwork, I will be better able to regulate or control the stress, if I know what things make me relax. Furthermore, the more you know about yourself, the better you will be able to fight off stressors that communicate to you that you are bad, incompetent, selfish, greedy, etc. Hence, if your husband is telling you that you are lazy and you have a strong sense that you are not, you will feel less stress.
Diehl & Hay (2010) found that amount of stress we feel is also influenced by the amount of control we feel we have. The more control people perceive to have over their environment and over their own selves, the less stress will affect them. It makes sense that the more control we feel we have, the less stressors are able to hurt us. The words “I want” or “I like” are repeated often in scales measuring perceived control. It appears that one needs to have a clear vision of what one wants and likes in order to feel control over life.
So, it is good to find out what pleasures you because it will strengthen you self-perception, self-regulation, and perceived control. HENCE, it will reduce stress in your life.
