The brain thrives on regularity, and as a result, getting enough natural light and managing stress levels during the coronavirus crisis are critical to aiding sleep, says neuroscientist and host of 'The Superbrain', Sabina Brennan.
Speaking on RTÉ's Today with Seán O'Rourke, Ms Brennan said that changes to our lives due to Covid-19 will undoubtedly affect our sleep patterns.
Sleep is regulated by three mechanisms, she said. The circadian rhythm over 24 hours, ranging from deep sleep and wake time.
Deep sleep, she said, usually happens between 2am and 4am, and during 1pm and 3pm, which is why we experience the "afternoon dip".
