Final answer:
Based on expert advice and research, bathing or showering every single day may not be necessary and can have negative effects on the skin. Alternative showering practices, such as taking cold showers, may have benefits for brain activity and stress reduction. Optimal showering frequency varies for each individual based on personal preferences and skin conditions.
Step-by-step explanation:
Evidence A: A Cleveland Clinic doctor who specializes in skin conditions recommends showering every two or three days. More than that, she warns, can strip the average person's body of its protective oils and cause itchy, dry skin.
Evidence B: An article in a medical journal questions the wisdom of taking only hot showers and instead advocates for cold showers. The article points out numerous benefits of cold showers, including increasing brain activity and reducing stress.
Based on these pieces of evidence, it can be concluded that bathing or showering every single day may not be necessary or beneficial for most people. Evidence A highlights the potential negative effects of daily showers on the skin's natural oils, leading to dryness and itchiness. On the other hand, Evidence B presents the benefits of cold showers, implying that alternative showering practices can be advantageous. Ultimately, the optimal showering frequency depends on individual preferences and skin conditions.
