6 Common Causes Of Insomnia

Insomnia is one of the most common sleep disorders seen today and is characterized by restlessness, frequent sleep interruptions, shorter than normal sleeping time and sometimes by complete wakefulness.

Aside from being very annoying, insomnia can result in sufferers losing their energy and enthusiasm, developing memory and concentration difficulties and feeling lethargic and frustrated. In turn this can lead to a reduction in work productivity and to accidents which may well have serious consequences.

There are a host of different things that can cause insomnia but here look at just 6 which are commonly linked to this sleep disorder:

1. The Environment. Our environment is extremely important when it comes to getting a good night's sleep and things like light, noise or extremes of temperature can cause insomnia.

2. Substance Abuse. Perhaps the most obvious form of substance abuse when thinking about insomnia is coffee and other drinks which contain high levels of caffeine. Smoking is another commonly accepted cause with heavy or chain smokers consuming more than enough nicotine to cause problems sleeping. What is perhaps less well known however is that this list of substances is quite long and even contains a number of herbal remedies which are used for a range of problems and which can lead to insomnia as a side effect. Lastly, we should not overlook alcohol. While it is true that alcohol can often make you feel tired initially once it is metabolized it can also keep you wide awake.

3. The Body Clock. We all have our own body clock or biological clock which works to regulate the sleep/wake cycle. If this body clock is upset by things like partying all night, burning the midnight oil studying in college or jet setting around the world on holiday or for business, then you will experience sleeping difficulties while your body clock re-adjusts.

4. Activities Prior To Bedtime. There are a number of things which can lead to insomnia if they happen within a reasonably short time of going to bed. Two of the most common are taking vigorous exercise shortly before retiring or eating a large meal when you are just about to go to bed. Both of these activities stimulate the body's metabolism and thus keep you awake.

5. Health Problems. There are many different health problems which are known to induce insomnia such as diabetes, heart failure, hyperthyroidism, ulcers, and Parkinson's disease. Asthma is also increasingly being recognized as a cause of insomnia, as is heartburn, the need for frequent urination and chronic pain resulting from such things as arthritis and leg cramps. The list here is very long indeed and also includes other forms of sleep disorder such as sleep apnea and a range of psychiatric conditions.

6. Emotional Distress. We all suffer from emotional distress from time to time and this can often lead to us becoming anxious or angry. However, when we bottle our feeling up inside ourselves rather than talking about them and seeking a solution for them then this frequently results in insomnia.
