Sleep matters for kids, especially when they are stressed. A new study led by researchers Jinshia Ly, Jennifer J. McGrath and Jean-Philippe Gouin from Concordia University’s Centre for Clinical Research in Health and the PERFORM Centre shows that poor sleep might explain how stress impacts health in kids.
A good night’s sleep
Getting a good night’s sleep might buffer the impact of stress on kids’ cortisol level, which is a hormone produced in the adrenal gland to regulate the body’s cardiovascular, metabolic and immune systems. While short-term exposure to cortisol prepares the body for the “fight or flight” response, long-term exposure to cortisol can put people at risk for health problems, like heart diseases, weight gain and depression.
