Lifestyle Causes of Insomnia
Insomnia can be triggered or perpetuated by your behaviors and sleep patterns. Unhealthy lifestyles and sleep habits can create insomnia on their own (without any underlying psychiatric or medical problem), or they can make insomnia caused by another problem worse.
Examples of how specific lifestyles and sleep habits can lead to insomnia are:
- You work at home in the evenings. This can make it hard to unwind, and it can also make you feel preoccupied when it comes time to sleep. The light from your computer could also make your brain more alert.
- You take naps (even if they are short) in the afternoon. Short naps can be helpful for some people, but for others they make it difficult to fall asleep at night.
- You sometimes sleep in later to make up for lost sleep. This can confuse your body's clock and make it difficult to fall asleep again the following night.
- You are a shift worker (meaning that you work irregular hours). Non-traditional hours can confuse your body's clock, especially if you are trying to sleep during the day, or if your schedule changes periodically.
Some cases of insomnia start out with an acute episode but turn into a longer-term problem. For example, let's say a person can't sleep for a night or two after receiving bad news. In this case, if the person starts to adopt unhealthy sleep habits such as getting up in the middle of the night to work, or drinking alcohol before bed to compensate, the insomnia can continue and potentially turn into a more serious problem. Instead of passing, it can become chronic.
Once this happens, worry and thoughts such as, "I'll never sleep," become associated with bedtime, and every time the person can't sleep, it reinforces the pattern.
This is why it's important to address insomnia instead of letting it become the norm. If lifestyle and unhealthy sleep habits are the cause of insomnia, there are cognitive behavioral techniques and sleep hygiene tips that can help. If you have tried to change your sleep behaviors and it hasn't worked, it's important to take this seriously and talk to your doctor.
