It's insomnia. To understand more about it, please read below.
*What are the types of insomnia?
Types of insomnia are differentiated by how long insomnia lasts (duration) and whether it is caused by an underlying condition.
Transient insomnia is short-term and may last one night, a few nights, or a few weeks. Transient insomnia (sometimes called acute insomnia) is usually linked to an emotionally exciting or stressful event such as a homecoming or an argument. Sometimes a change in time zone (â€śjet lagâ€ť) or sleep schedule can bring on a bout of transient insomnia.
Chronic insomnia is long-term and may last a month, several months, or years. Chronic insomnia (also called constant insomnia) occurs on some or most nights, so it is considered ongoing. Chronic insomnia may be caused by either a medical problem, a psychiatric problem, a sleep disorder, or poor sleep hygiene. Self-help may solve the poor sleep habits, but professional help may be necessary for sleep disorders or for underlying medical or psychiatric problems.
Primary insomnia has no known underlying condition (insomnia is the problem). Primary insomnia is the most common type of insomnia and is usually caused by learned maladaptive sleep patterns.
Secondary insomnia is a symptom of another underlying (preexisting) condition problem that causes the insomnia. When you receive effective treatment for the underlying condition, the insomnia usually goes away.
*What causes transient insomnia?
Transient insomnia lasting a few days is usually caused by:
Stress â€“ A temporary stress (conflict or environmental change) such as starting a new job; an upcoming test at school; a family or marriage problem; financial difficulties; a death in the family; or moving to a new house or city can be a cause of insomnia. Such a stress causes a positive or negative change in mental state: the person may feel anxious, excited, worried, angry, griefstricken, euphoric, afraid, sad, hopeful, or apathetic.
Change in your environment or work schedule â€“ Working a late or early shift or travel across time zones disrupts your bodyâ€™s circadian rhythms making you unable to get to sleep when you want to .
Transient insomnia lasting more than a few days, but less than a month, is usually caused by a more enduring unsettling life event or stressor, such as a divorce, job loss, move to a new location, or death in the family.
*What causes primary chronic insomnia?
Insomnia brought on by poor sleep habits, a disruptive sleep environment, or an inability to get enough sleep is called primary insomnia because insomnia is the condition to be treated. Some of the reasons for primary insomnia include (see Tips for a Good Night's Sleep for a more complete list):
Caffeine. Drinking caffeinated beverages (coffee, tea, cola) or eating chocolate in the afternoon or evening. Caffeine can delay sleep and wake you up from sleeping. More than four caffeine drinks per day interferes with sleep.
Alchohol. Drinking alcohol in the afternoon or evening. Alcohol may help you fall asleep, but it disrupts the second half of your nightâ€™s sleep.
Nicotine. Smoking cigarettes in the six hours before bedtime. Nicotine is a stimulant.
Naps. Excessive napping in the afternoon or evening. More than two naps late in the day will interfere with sleep.
Exercising within three hours of bedtime. Exercise stimulates the body by raising the heart rate and metabolism. Exercise late in the day interferes with sleep, but exercise earlier in the day helps you sleep well at night.
Excessive liquids. Liquids increase the need to get up and urinate during the night.
Mentally intense activities at bedtime (such as computer work).
Eating too much too late in the evening. Having a light snack before bedtime is OK, but eating too much may cause you to feel physically uncomfortable while lying down, making it difficult to get to sleep. Eating heavy, spicy, or high-sugar foods at night may cause indigestion
Trying too hard to fall asleep. Can occur when you worry excessively about not being able to sleep well and try too hard to fall asleep. Most people with this condition sleep better when they're away from their usual sleep environment or when they don't try to sleep, such as when they're watching TV or reading.
Noise. Too much noise in the environment (even if you fall back asleep) can prevent you from sleeping well or cause frequent awakening.
Light. Light affects your brainâ€™s production of the hormones that regulate sleep rhythms. Too much light in the bedroom can keep your body from deep sleep.
Room temperature. You will be restless if you are too hot or cold; a comfortable room temperature is best.
Uncomfortable or too small bed.
Sleep partner or other family members. A sleep partner who snores, has sleep apnea, is very restless, gets up frequently, or has difficulty sleeping will affect your ability to sleep. Interruptions from other family members, such as a toddler or new baby, can also keep you up.
*What causes secondary chronic insomnia?
Pain and depression are the two most common underlying conditions for chronic insomnia. The underlying conditions can be physical medical conditions or psychiatric conditions. This type of insomnia is often called secondary insomnia because the insomnia is a symptom of the underlying condition. Some conditions or situations that commonly lead to insomnia include:
Depression. You may either sleep too much or have trouble sleeping if you're depressed. This may be due to chemical imbalances in your brain or because worries that accompany depression may keep you from relaxing enough to fall asleep when you want to.
Pain. Medical conditions that cause pain often cause insomnia as well. For example, acid reflux (return of stomach contents into the esophagus),fibromyalgia or other chronic pain syndromes, heart disease, and arthritis, along with countless other conditions often cause sleeplessness.
Stress. Concerns about work, school, health or family can keep your mind too active, making you unable to relax. Excessive boredom, such as after retirement or during a long illness, may occur and also can create stress and keep you awake.
Anxiety. Everyday anxieties as well as severe anxiety disorders may keep your mind too alert to fall asleep.
Menopause. Between 30% and 40% of menopausal women experience insomnia; this may be due to hot flashes, night sweats, anxiety, and/or fluctuations in hormones.
Menstruation. Hormonal changes during the menstrual cycle can cause insomnia; sleep tends to improve mid-cycle with ovulation.
Growing older. Changes associated with aging include changes in sleep patterns (more time in Stages 1 & 2, less time in stages 3 & 4); becoming less physically and socially active; hormonal changes, and health problems which cause more chronic pain.
Long-term use of sleep medications. Sleeping pills often become less effective over time. If a person suddenly stops taking or becomes tolerant of a long-term prescription medication,
insomnia may result. If you need sleep medications for longer than a few weeks, take them no more than two to four times a week, so they don't become habit-forming.
Medication side effects. Prescription drugs, including some antidepressant, high blood pressure and corticosteroid medications, can cause sleeping difficulties as a side effect .
Many over-the-counter (OTC) medications, including some pain medication combinations, decongestants and weight-loss products, contain caffeine and other stimulants. Antihistamines may initially make you groggy, but they can worsen urinary problems, causing you to get up more during the night.
Caffeine, alcohol, recreational drugs and smoking. Consuming excessive amounts of caffeine, alcohol, recreational drugs, smoking can cause restlessness and smoking cessation may also result in temporary insomnia. If you use alcohol to help you fall asleep, you may have insomnia when you do not use it. Alcohol in any amount negatively affects sleep quality and duration.
Other medical conditions. Other causes of secondary insomnia include sleep apnea, restless legs syndrome, circadian rhythm disorder, arthritis, kidney disease, heart failure, asthma, sleep apnea, narcolepsy, restless legs syndrome, Parkinson's disease and hyperthyroidism.
