Sleep is often underestimated yet it plays a crucial role in maintaining overall health and well-being. From glowing skin to a healthy heart, the benefits of quality sleep extend far beyond just feeling rested. It’s during sleep that the body undergoes critical repair, restoration and rejuvenation processes, making it a cornerstone of a healthy lifestyle. In a conversation with The Daily Jagran, Dr. Vikas Mittal, Director – Pulmonologist at the CK Birla Hospital, Delhi explained how sleep affects everything from skin to heart.
How Sleep Impacts Skin?
One of the most visible effects of good sleep is reflected in our skin. During deep sleep, blood flow to the skin increases, aiding in cell repair and collagen production. This helps reduce the appearance of wrinkles, dark circles and dullness. Chronic sleep deprivation, on the other hand, can accelerate ageing, lead to inflammation and make skin conditions like acne or eczema worse.
How Sleep Impacts Heart?
Beyond appearance, sleep is vital for heart health. It helps regulate blood pressure, manage stress hormones like cortisol and reduce inflammation in the cardiovascular system. Inadequate or poor-quality sleep is linked to an increased risk of high blood pressure, heart attacks and stroke. Over time, chronic sleep issues can contribute to metabolic problems that elevate heart disease risk.

A lack of sleep weakens our immune response, making us more vulnerable to colds, flu, and other health issues. Moreover, mental health and cognitive function are tightly linked to sleep. A good night’s rest boosts memory, mood concentration, and emotional resilience.
