While most people focus on diet and hydration to boost their immune system, new research from a leading physician highlights a less obvious, yet powerful influencer: quality and consistency of sleep. Contrary to popular belief, what we consume plays a secondary role compared to how well we rest. The doctor explains that sleep regulates the production of cytokines-proteins crucial for targeting infection and inflammation-making uninterrupted, deep sleep essential for an effective immune response.

Studies show that even a single night of poor sleep can reduce the ability of the immune system to respond effectively to pathogens. This revelation shifts the conversation from commonly discussed food and drinks to the need for a healthier bedtime routine.
