I am very sorry to know that you gets sick within a week. It looks like that you don’t take care of your health. Early wake-up and light exercises can work. Five times pray makes the open parts of the body get washed and indeed it’s the cure for many diseases. And sometimes we do not weigh any trivial disease and then time comes when it grows to a serious problem. In the same way, we do not prevent things that effect negative on our health and the virus of some diseases get way to be strong enough and our health deteriorates. You had better consult a proper physician and follow his instructions so far so good.
