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.
Insomnia not only affects your quality of life. It can negatively impact your treatment and increase risks for other physical and mental health problems. For example, cancer-related fatigue, daytime sleepiness (hypersomnia), anxiety and depression are commonly reported in people who experience sleep disturbances.
