What happens inside the body that causes insomnia?

What Causes Insomnia?

Sleep is one of the most important parts of our life. Insomnia can be defined as the difficulty in getting, maintaining and beginning the various stages of sleep. Insomnia can also be called sleeplessness, or just plain inability to sleep. Why does sleep affect us is the question to be answered. Generally it is due to the disturbance in the nervous system of an individual causing sleep disorders. Sleep and circadian rhythms are disturbed in the body and that is the reason insomnia is initiated. Insomnia results mainly due to other problems occurring in our life. The reason and nature of insomnia may be different varying from person to person as every individual has his or her own body mechanism.

The problems that can initiate insomnia can be listed as follow:

• Stress
• Emotionally disturbances such as hopelessness
• Anxiety and Work
• Traumatic experiences
• Medications

So when a person is stressed out due to the hard work encountered all the day and somehow he does not get a chance to sleep properly it affects the nervous system and the neurons responsible for initiating the sleep cycles and they may start working improperly. Same goes for emotional disturbances and hopelessness, the part of the brain responsible for controlling emotions can get affected in cases of breakups, failure in completing some assigned task, failure in examinations, failure to get a job and many more.

Anxiety, depression and insomnia

Scientists are convinced that anxiety, depression and insomnia are linked in a strong way even if the absolute full details of this link might remain unknown. Anxiety and depression can make a person drink alcohol more than the person without it and lack of sleep can cause and add to more damage to the part of brain responsible for sleep cycles. Apart from it traumatic experiences such as sudden death of some relative, accidents etc. can damage the growth patterns of sleep as well. If a person is sick he or she may have been taking some medications that prevent sleep as a side effect as most medicines can seriously affect the response of nervous system in our body. Thus, all in all anything that disturbs the pattern of sleep cycles, nervous system and brain functions is the reason for your insomnia. Measures should be taken seriously to avoid insomnia as it can lead to many other sleep disorders as well.
