Causes of insomnia

Although there are many causes of insomnia, two are considered to be the major culprits, these are psychological causes and physical causes.

Psychological issues can cause insomnia.

  • Anxiety or a feeling where people feel increased tension, apprehension.
  • There are feelings of fear, worry and uncertainty. These can occur due to other people’s effects on us.
  • There can be financial worries, concerns over relationships or many other causes.
  • Stress could be another cause of insomnia. A person has to effectively cope with any emotional, physical, social and economic factors which induce response.
  • Another factor or cause of insomnia can be depression. Depression is caused due to mood disturbance. This can be characterized by feelings such as sadness, despair and discouragement.

Lack of a good night’s sleep can create psychological problems. For your psychological problems, you can take professional counseling from a doctor, therapist or sleep specialist. These specialists can help you cope with any of these conditions.

Physical causes of insomnia.

  • These can be hormonal changes in women. Hormonal changes can include premenstrual syndrome, menstruation, pregnancy and also menopause.
  • Another factor which can cause insomnia is decreased melatonin. The levels of melatonin decrease as the person grows older. This is a hormone that helps control sleep. By the time a person reaches the age of 60, the body produces very little melatonin.
  • Insomnia is also a symptom of hyperthyroidism.

Medical conditions can be another factor to cause insomnia.

Medical factors can include allergies, asthma, heart disease, high blood pressure, hyperthyroidism and Parkinson’s disease. Pain and discomfort from a medical injury often disturbs the sleep. Sleep apnea is a state where one temporarily stops breathing during sleep. This can be another factor which can lead to lack of sleep. You could also have periodic leg and arm movements during sleep.

Some temporary events or factors can lead to lack of sleep.

This can include adjustment sleep disorder. Sleeplessness due to this is a reaction to change or stress. This kind of sleeplessness may be caused due to a traumatic event. This can include illness or loss of a loved one. This can also include a minor event such as a change in the weather or a strong argument with someone. Some people also get insomnia due to jet lag due to difference in time zones. Individuals working night shifts also encounter sleeplessness. If you are working in night shifts, it can be troublesome to adjust your sleeping habits.

Insomnia could also be a side effect of medications like Lipitor.

Lipitor is a drug used for lowering cholesterol levels. However, this drug can cause serious side effects. One of these is that Lipitor causes insomnia.

Why take Lipitor?

Atorvastatin, which is the generic name for Lipitor, is something that is used in the fight against high cholesterol levels. It blocks the production of cholesterol in the body. This is therefore an important drug for many because it reduces the risk of heart attack or other coronary diseases.

Side effects

There can be serious side effects when taking this drug. One of these is that the drug causes sleeplessness. Sometimes you might only get a couple of hours a night. Therefore, make sure that the problem you have with cholesterol is severe enough to call upon using Lipitor.

The body needs certain levels of cholesterol to function. Therefore, taking this drug might be actually creating another problem, which is that your body is now lacking appropriate levels of cholesterol. This is something that needs to be considered in relation to this drug.

How to sleep while on Lipitor?

When it comes to insomnia it is important to note that there are medicines to help you sleep if Lipitor is something that is essentially necessary for you to take. Remember, however, that these sleep aiding drugs are not meant to be taken for a long period of time. This is why Lipitor should also be used only for a short period when cholesterol levels are at a point where taking the drug is necessary.

In addition to insomnia you may experience fatigue while on this drug. Therefore, it does not work in a way that perks you up, but rather creates insomnia so that you cannot sleep and because of not getting sleep you feel constantly tired.

These are some of the reasons Lipitor causes insomnia. Consult your doctor about other medicines and remedies for high cholesterol before deciding to undertake Lipitor treatment.

Excessive consumption of caffeine can also lead to sleeplessness.

What is Caffeine?

Caffeine is a colorless and flavorless addictive drug that is found in many of the foods and drinks that we all consume. Coffee contains large amounts of this stimulant. It can also be found in cola drinks as well as chocolate. Often medications use caffeine to produce a stimulating effect. To most people it causes a more alert state, which makes it more difficult to fall asleep. Different people are affected differently. Some can drink many cups without effect on how they sleep. Some are more sensitive. This is usually dependent on how your metabolism has adjusted to caffeine.

Caffeine and Sugar

Many products combine caffeine with sugar. Some of these are chocolate, cocoa and sodas. Sugar acts with the caffeine to produce an increased stimulating effect. Energy drinks are also filled with caffeine, sugar and other stimulating substances. This is why they can causeinsomnia when used before bedtime. For some people the effects can last for several hours. This should be taken into account if insomnia occurs after caffeine ingestion.

How Caffeine Works on Your Brain?

Caffeine stimulates the brain in same ways as amphetamines, cocaine, and heroin. Although the effects of caffeine are milder than other drugs, it is still causing your brain to function differently than normally. If you are not able to function without the aid of caffeine in your life, then you are likely to be addicted to it. If your sleep is disrupted for more than two weeks, then it is likely that you are suffering from insomnia. By leaving out caffeine from your diet, you can test whether this is the cause of your insomnia.

Cigarette smoking, especially before bed time is another cause of insomnia.

There are several contributors to lack of sleep. Some of the reasons for people not being able to sleep are in what they ingest. Therefore, if you drink caffeine or other stimulants before bedtime, it might prevent you from falling asleep. Cigarettes are a stimulant too. This is why they can also be in the way of getting to sleep. If you smoke a cigarette before bedtime it causes an elevation in your alertness and diminishes drowsiness.

Symptoms of Smoking Cigarettes Before Bedtime

  • Alertness
  • Elevation in blood pressure
  • Headache
  • Faster reaction time
  • Insomnia

All of these reasons make it more difficult to fall asleep. It is because alertness and increased heart rate make you feel as if you should be focusing and getting ready for physical activity. Smoking produces stimulations in nerve ending throughout the body. This makes sleep more difficult to achieve. Smoking cigarettes before bedtime can affect your ability to fall asleep by reducing the amount of serotonin produced in the pineal gland in the brain. This chemical substance causes us to fall asleep. When the amount of it is reduced, you are not able to get to sleep.

Remedies for Cigarette Related Sleeplessness

One obvious cure to insomnia caused by cigarettes is to quit smoking. This is the most effective way to cure cigarette related insomnia. But this might be difficult to achieve because cigarettes form a powerful addiction because they affect the way the pleasure centers in the brain, operated through endorphins, are activated.

If it is not possible to quit smoking there are other ways that cigarette related insomnia can be alleviated. If you need to continue smoking, do so a good while before bedtime. The effects of cigarette smoking do not last for many hours. Therefore, stopping smoking right before bedtime is a good way to reduce the symptoms of insomnia caused by cigarettes.
