Have you ever had one of those nights where you just can’t seem to fall asleep?
While that happens to everyone every occasionally, people with insomnia have to deal with these symptoms night after night.
Some people with insomnia have trouble falling asleep, whereas others wake up throughout the night, and struggle to fall back asleep.
These disturbances typically happen at least 3 times each week.
Insomnia affects both the quantity and quality of sleep, which makes it hard for individuals to reach restorative levels of sleep, leading to daytime sleepiness and fatigue, and over time, feelings of irritability, anxiety, and depression.
This can cause professional and personal problems, as make day-to-day activities like driving more challenging and dangerous, with people struggling to stay awake on the road.
Although insomnia can happen without an underlying cause, it can also accompany and worsen other problems like pulmonary diseases, psychiatric conditions, and a whole variety of conditions that might cause pain.
Finally, and probably most commonly, insomnia can be the result of daily stresses from work or relationships as well environmental factors such as having to work a night shift, or having a newborn baby.
There are a number of biological factors associated with insomnia.
