Understanding the Body’s Internal Clock
Our bodies follow a natural 24-hour cycle known as the circadian rhythm , which regulates sleep and wakefulness. According to Dr Ravivarma A, Consultant Clinical and Interventional Pulmonologist at Prakriya Hospitals, Bengaluru, 'sunlight exposure helps the body know when to be alert, while fading light triggers melatonin production, signalling it’s time to rest.'
