A possible reason in such stories is a magical transformation. For instance, she might have made a deal with a magical being, and as part of the deal, she gets taller. Or perhaps she entered a magical forest where the plants emit a gas that causes abnormal growth. Also, in a more psychological sense, it could be her own self - belief and confidence that somehow manifests physically as height increase, although this is more of a metaphorical take on the 'gets taller' concept in a story.
In 'wife gets taller' stories, one reason could be a genetic mutation. Maybe there was some dormant gene in her DNA that suddenly activates, causing her to grow taller. Another reason could be exposure to some strange radiation or energy source. It might be like in science - fiction where an alien device emits a ray that affects her body's growth hormones.
Exercise plays a big role. For example, Pilates focuses on body alignment and balance. By regularly doing Pilates, a wife can elongate her spine and muscles, making her look taller. Also, exercises that strengthen the back muscles can pull the shoulders back and make one stand straighter.
Self - confidence. Many wives may feel more confident in their appearance after breast augmentation, which can improve their quality of life.
One possible reason could be a hormonal imbalance. For example, if there was a problem with the thyroid gland and it started functioning differently, it might affect growth hormones. Another reason could be related to bone health. Maybe there was a discovery of a new treatment for a bone - density - related issue that had an unexpected side effect of promoting growth in adults.
I don't really have a specific 'wife gets taller' story at hand. But perhaps in a fictional story, a wife could get taller due to some magical spell or a strange scientific experiment gone wrong. For example, she might accidentally drink a potion that has the side effect of continuous growth, and then she has to deal with things like buying new clothes, adjusting to a new height in the house, and how her relationship with her husband might change as a result of this sudden physical change.
Medical conditions might also play a role. Some hormonal imbalances, when corrected, could cause a change in height. For instance, if there was an issue with the growth hormone or thyroid hormones, and it has been treated recently, it could lead to an increase in height. However, this is quite rare in adults, but not unheard of.
In old literature, one reason could be the reflection of the patriarchal society at that time. Men held more power, and such stories might have been used to enforce the idea of male dominance. Another reason could be for shock value or to create a sense of 'otherness' in the story.
One reason could be proper nutrition. Eating foods rich in calcium like dairy products, and vitamins such as fruits and vegetables helps bones grow. Another is regular exercise. Exercises like running, jumping or sports like basketball can stimulate growth hormones. Also, getting enough sleep is crucial. During sleep, the body releases growth hormones which contribute to height increase.
One reason could be genetics. Maybe the wife has genes that cause a later growth spurt. For example, some people grow taller in their late teens or early twenties. Another reason could be related to health. If the husband has an underlying health issue that stunted his growth, while the wife is in good health and has a normal growth process, she may end up taller. Also, lifestyle factors like diet can play a role. If the wife has a diet rich in nutrients necessary for growth, such as calcium and protein, it might contribute to her taller stature compared to her husband.
One reason could be lack of emotional connection in the marriage. If a wife feels unheard or unloved, she might be more prone to look elsewhere.
One reason could be jealousy. A person who is jealous of the wife's happy marriage or her status might try to blackmail her to create chaos in her life.
