When you develop insomnia, one of the issues is when you go to bed and try to get to sleep, but instead, your mind starts to race, running thoughts up to the point that it causes you to feel sleep-deprived.

And so there is mental conditioning in which your mind is programmed into not going to sleep because your mind believes that the bed is a place to think.
Increased arousal, often related to fear of not sleeping or being unable to function effectively during the day, prevents the usual functioning of brain systems which initiate and maintain sleep. — John Cline Ph.D.
In brain development, insomniacs or people with chronic insomnia show more plasticity and activity in the brain. Plasticity is the brain’s ability to adapt and change to different environments and situations. The consequence of too much plasticity in the brain tends for insomniacs to develop difficulty sleeping. That is because of the multiple working neurons acting as agents for them to think about a lot of things and even overthink about possible events in the future. Some experts believe that too much brain activity of insomniacs causes the brain to fight with itself when it is about to sleep.

Insomnia disturbs both the quality and quantity of sleep and reduces an individual’s ability to attain a restorative sleep which eventually causes fatigue, daytime sleepiness, the feeling of anxiousness over time, irritability, and worst, depression.

Routine things like locking up the house, drinking a cup of tea, putting on pajamas, washing your face, and brushing your teeth can become rituals when performed regularly and consistently before bed. Your brain eventually associates these things with winding down and going to sleep. — Megan MacCutcheon, LPC

Intake of alcohol or drugs to fight off insomnia has its side effects, one of which includes being dependent on the substance which can cause further damage to the sleep rhythm of the body when the intake stops. The body starts to crave more of the substance, and it releases stress hormones if the tolerance level due to substance intake in the body does not meet up with the required dosage of such substance in the body.
