Praise is due to Allah; and prayers and peace be upon His Prophet, his family, and his companions.

On Saturday, April 23^th, 2011, (corresponding to Jumada-1 20, 1432 H) we have launched the English version of the ‘Encyclopedia of Sleep in Health and Disease’ in a contemporary design. Staying in line with the original website, we now provide valuable information in both Arabic and English languages.

We have employed stat-of-the-art technologies in website designing and programming for making our services easily available. Additionally, we carry regular updates about the latest contributions relating to sleep disorder and thoracic diseases.

As a result, we have rightfully changed the website’s title from ‘Sleep in Health and Disease’ to all-encompassing title - ‘Encyclopedia of Sleep in Health and Disease’.

We wish to help you get all the required information and medical assistance about sleep disorder and chest diseases under one roof. You are welcome to give us your valuable feedback and we will try to incorporate the same.
