When you’re feeling stressed on the job, it can be hard to leave work at the office. Your job may preoccupy your mind as you drive, as you eat, and as you interact with family or friends. But the battle to control your mind can intensify when you try to go to sleep.

Sleep and stress are competitors. When stress continually activating a part of the brain that is otherwised used for sleep, then stress wins the tug-of-war.

According the AASM, job stress can be a cause of adjustment insomnia. This involves disturbed sleep or sleeplessness that may last for a few days or a few weeks. Other symptoms may include anxiety, worry and tension.

A common feature of adjustment insomnia is “ruminative thoughts.”  This is when you dwell on the same thoughts, chewing them over and over in your mind. You may lie in bed staring at the ceiling, unable to stop thinking about work. Even when you finally fall asleep, your work may invade your dreams. The Staples National Small-Business Survey polled 302 owners and executives of small businesses, and more than half said they dream about work -or “sleepwork.”

Scientific research confirms that job stress can affect your sleep. In 2005 a study in the journal Sleep involved 8,770 Japanese workers. In both men and women, a high level of stress at work was liked to insomnia.

A 2007 study in the International Journal of Behavioral Medicine linked insomnia to these three types of job stressors:

• High work demand
• Low influence over decisions
• High professional compromise

The type of job stress you experience may affect your sleep in different ways. Another study linked work overload to poor sleep quality.  Having role conflicts at work was related to non-restorative sleep and trouble falling asleeo or staying asleep.

According to the National Institute for Occupational Safety and Health, sleep disturbances are one early warning sign of job stress. Others may include:

• Headaches
• Difficulty concentrating
• Short temper
• Upset stomach
• Job dissatisfaction

Job stress may be unavoidable. But sleep specialists say you can take steps to improve your sleep even when you are stressed.  Establishing a pattern of relaxing behaviors close to bedtime and limiting work to the early evening may help to reduce stress.
