Sleeping
You may find your sleep pattern has changed. This is probably due to the disruption of sleep in intensive care and on the wards. Your body is less active, the wards may be noisy and you may have received drugs in intensive care, which will have changed your sleep pattern.
Some intensive care patients experience nightmares or strange dreams whilst in intensive care, which may continue on the ward. Occasionally the dreams are disturbing, and are likely to be caused by a combination of; the drugs you received, altered hormone levels and your disrupted sleep pattern. Discuss your experiences with the ward doctors and nurses. These dreams or nightmares do subside over a few days or weeks.
Lack of sleep may make you feel very tired and lethargic. It is important to remember lack of sleep over a short period of time will do you no harm, and as you recover, your sleep pattern will return to normal.
