Can't Sleep? What's Causing Your Insomnia?

Do you struggle to fall — and stay — asleep? Occasional insomnia isn’t uncommon. A big cup of coffee right before bed can make it difficult to get a good night of sleep. Researchers found that nearly 25% of Americans struggle with acute insomnia. 

But if your insomnia occurs more than three times a week and lasts for more than three months, you might be dealing with chronic insomnia.

Fortunately, insomnia is treatable, but you first need to consider the root cause of your insomnia. At TMS Treatment Center, board-certified psychiatrist Jacob Bishop, MD, and board-certified neuropsychologist Peter Gager, PhD, can help you get the sleep you need.

In the meantime, you can read about some of the most common causes of insomnia.

5 causes of insomnia

Sleep is essential for your mental and physical well-being. If you’re not getting the quality or quantity of sleep you need, it’s vital to determine what’s causing your sleep troubles. 

Insomnia has many causes, including:

Uncomfortable environment 

Sleep experts from the National Sleep Foundation suggest that the ideal room for sleeping is:

In addition to a comfortable room, the right mattress makes a big difference too. Sleeping on a worn-out mattress can cause back or hip pain and can affect your ability to sleep. 

If you suspect that any of these environmental factors are affecting your ability to sleep through the night, try making a few modifications to your bedroom.


Stress is a big culprit when it comes to insomnia. Stress — at work or in your personal life — can cause both acute (temporary) or chronic (long-lasting) insomnia. You might see stress-induced insomnia in several ways:

If you don’t get enough sleep, you’re more at risk for daytime sleepiness and brain fog, which can make stressful situations harder to manage. 


Chronic pain also makes it hard to fall asleep. This includes pain from conditions like arthritis as well as pain from injuries.


Certain medications affect your sleep cycles as well. These include:

This is just a small list of medications that may cause insomnia. If you find that your medication is affecting your ability to sleep well, see your doctor. Don’t alter your medication regimen unless directed to do so. 

Depression and anxiety

Depression can cause feelings of sadness, but it can affect your sleep habits too. Depression causes some people to sleep more, but it can contribute to insomnia. 

Anxiety can also increase the risk that you’ll wake up too early, wake up feeling unrefreshed, or even wake up during the night with racing thoughts.

Jet lag

Jet lag temporarily causes insomnia, but insomnia caused by jet lag is often rectified quickly. If you’re experiencing jet lag, try to assume the time of your local environment for the easiest transition. Naps may prolong your adjustment.
