El sueño juega un papel vital en la buena salud y el bienestar a lo largo de su vida. La forma en que se siente mientras está despierto depende en parte de lo que sucede mientras duerme. Durante el sueño, su cuerpo está trabajando para mantener una función cerebral saludable y conservar su salud física. En niños y adolescentes, el sueño también ayuda a apoyar el crecimiento y el desarrollo. Con el tiempo, dormir de manera inadecuada puede aumentar su riesgo de tener problemas de salud crónicos. También puede afectar qué tan bien piensa, reacciona, trabaja, aprende y se lleva bien con los demás.
