Health impact of wearing a very tight bra

Tight bras give you a fuller and more enhanced bust and more importantly, gives support and shape. Some woman are so used to wearing bras that they even wear one when they sleep! However, a recent study conducted at the Harvard university, has linked wearing tight bras to breast cancer. This is because wearing a very tight bra can restrict blood circulation and can also impair the lymph tissues.
According to the study, less oxygen and fewer nutrients are delivered to the cells, while waste products are not flushed away. This is especially the case with women who wear bras for more than 12 hours a day and even sleep in them. The study also discovered that middle-class women are at a higher rick of breast cancer since they work for longer hours.
