A cortisol blood test is conducted to discover the cortisol hormone level in the blood. Cortisol assists the body in metabolic process stress management. The levels of cortisol inside the blood are vastly different as a result of several factors like stress, infection, injury and strenuous activities. The levels of cortisol usually vary in the length of your day. In the morning, it's generally increased, and at night and during sleep, its level is often low. Its level, however, may follow the person's sleeping habits. Those who sleep within the daytime and so are awake during the night, could have reversed cortisol level patterns also. In the pre-planning stages, governments should already mobilize relief authorities and create safe havens for victims or displaced visitors to retreat to. They should also have rehabilitation plans ready at their disposal. Another important thing is to physical and mentally prepare the citizen concerning the shock that is included with disasters, coping with it, using effective thinking to keep themselves mobilized and staying safe, secure and motivated a direct consequence of the disaster. Disaster relief supplies are an integral part of this pre-planning. There are many organizations which manufactures these supplies; they must follow UNHCR specifications as well as follow international quality control and standards to be viable.
