A reaction to change or stress is one of the most common causes of short-term and transient insomnia. This condition is sometimes referred to as adjustment sleep disorder.
The trigger could be a major or traumatic event such as:
Temporary insomnia could also develop after a relatively minor event, including:
In most cases, normal sleep almost always returns when the condition resolves, the individual recovers from the event, or the person becomes used to the new situation. Treatment is needed if sleepiness interferes with functioning or if it continues for more than a few weeks. Individual responses to stress vary and some people may not experience insomnia at all, even during very stressful situations while others may suffer from insomnia in response to very mild stressors.
Fluctuations in female hormones play a major role in insomnia in women over their lifetimes. This insomnia is usually temporary.
Air travel across time zones often causes insomnia. After long plane trips, 1 day of adjustment is usually needed for each time zone crossed. Traveling west to earlier times seems to be less traumatic than going east to a later time because it is easier to lengthen a circadian phase than to shorten it.
Light, noise, and uncomfortable temperatures can cause sleeplessness. Depending on the time of day, too much or too little light can disrupt sleep.
Caffeine. Caffeine is a stimulant, which can interfere with falling asleep.
Nicotine. Nicotine is also a stimulant, but quitting smoking itself can lead to transient insomnia.
Partner's Sleep Habits. A partnerā ' s sleep habits, including snoring, can impair oneā ' s own sleep.
Medications. Insomnia is a side effect of many common medications, including over-the-counter preparations that contain caffeine. People who suspect their medications are causing them to lose sleep should check with their doctors or pharmacists.
