Assess your present medical conditions
Lack of sleep can actually result in serious medical conditions. However, this also works the other way around. It is also a fact that serious medical conditions can disrupt sleep. Several serious medical conditions can actually disrupt the quality of sleep that the body needs. A runny nose, coughing, and hay fever caused by severe colds do not attack only during daytime, but during night time as well. If you are suffering from any of these, visit your doctor to get appropriate treatment started. Proper rest will boost the immune system so that you can avoid getting sick again.
