Iâm pregnant and have had a blood test for chickenpox. The blood test can show that you: 1  Are immune (have already had varicella disease or varicella vaccine) and have no sign of recent infection. You have nothing further to be concerned about.  Are not immune and have not yet been infected.
Causes of acute insomnia can include: 1  Significant life stress (job loss or change, death of a loved one, divorce, moving) 2  Illness. 3  Emotional or physical discomfort.  Environmental factors like noise, light, or extreme temperatures (hot or cold) that interfere with sleep.
This is important because most people with insomnia have more than one contributing factor causing their sleep difficulties. For example, while someone might attribute their insomnia to fear of falling asleep, it might actually be caused by unacknowledged Restless legs syndrome (a common cause of severe insomnia). Your distress is justified; Insomnia has a devastating effect on Quality of Life.
