What is insomnia? 

It can be short-term, or it can last a long time. But the problem is always falling or staying asleep. Acute (short-term) insomnia may be caused by stress, illness, travel, or environmental factors. Long-term (chronic) insomnia can be caused by underlying psychological and physical conditions. 

Who is at risk? 

Women are more likely to experience insomnia than men. Insomnia is more common in older people. 

Diagnosing Insomnia 

Your doctor will diagnose insomnia by examining your sleeping patterns. Your doctor may ask, “

• How long do you take to fall asleep? 
• How often do you get up in the middle of the night? 
• Are you experiencing fatigue during the day? 
• Have you been diagnosed with a medical condition that may affect your sleep? 
• What medications are you taking (including prescription drugs and over-the-counter drugs as well as herbs or supplements)? 
• Do you smoke or drink alcohol? 

You may be asked by your doctor to keep a sleeping diary in which you can record sleep-related data. 

Treating Insomnia 

• The most important thing to do when trying to control insomnia is to practice good sleep hygiene. Simple self-help methods include setting a regular bedtime, controlling mealtimes, drinking fluids, and limiting caffeine. 
• Cognitive behavioral therapy is effective in treating chronic insomnia in people of any age. It involves a variety of approaches to help people establish new sleep habits and relax. 
• If behavioral or self-help therapies fail to solve the problem, your doctor may prescribe medication for short-term use. 

The most commonly prescribed sedative-hypnotic drugs are those that do not contain benzodiazepine. These include zolpidem, zaleplon, and eszopiclone. Ramelteon (Rozerem generic) and Suvorexant (Belsomra) are two newer types of sedative-hypnotics. 

Sedative hypnotics all have side effects. Ask your doctor about the possible risks and precautions. 

The following is a brief introduction to the topic: 

Insomnia is derived from the Latin for “no sleeping.” Insomnia can be characterized by the following: 

• Sleeping difficulties 
• Sleeping problems
• Wake up problems 
• Sleeping in early. r quality (non-restorative) bed

Insomnia can be pr-mary or secondary.

• Primary bed omnia is the term secondary. describe a sleep disorder that occurs on its own and does not result from other medical conditions.
• Comorbid insomnia is a condition that occurs when other medical conditions interfere with sleep. The condition is sometimes conditions. ndary” insomnia, although it’s not clear whether the conditions are what caused insomnia. 

Duration of Insomnia 

Insomnia can be classified by the length of time it lasts. 

• Transient insomnia lasts a few days. 
• Insomnia that is short-term (acute). 
• Chronic (long-term) insomnia lasts a month or more. 

Related Disorders 

Insomnia can also be defined as the inability to fall asleep at regular times. Circadian rhythm disorders include the following examples: 

• Delayed Sleep-Phase Syndrome is a syndrome in which you fall asleep late at night or very early in the morning and have difficulty waking up the next morning. This syndrome is most common in adolescents. 
• Advanced Sleep-Phase Syndrome is characterized by a pattern in which you fall asleep in the early evening (between 6 and 9 p.m.), wake up early in the morning (3 to 5 a.m.), then are unable to go back to sleep. This syndrome is more common in older adults. 

Healthy Sleep 

According to studies on sleep behavior, people spend approximately one-third of their time sleeping, indicating that they need 8 hours of sleep per day. Adults differ in how much sleep they require to feel rested. Infants can sleep up to 16 hours per day. 

A circadian rhythm (meaning “about one day”) is used to describe the daily cycle of living, including sleeping and waking. This rhythm is also known as the biological clock. The circadian rhythm is a biological clock that controls hundreds of bodily functions. However, sleeping and waking are the two most important. 

The cycle of sleeping and waking lasts approximately 24 hours. The daily pattern is usually as follows: 

• Activities during the day and rest at night. 
• The traditional siesta is a natural time of sleepiness. 

The daily rhythms can also be affected by other factors. 

• Women’s monthly menstrual cycles can change the pattern. 
• The light signals that enter the eye reset the circadian rhythms each day. Changes in seasons or exposure to light and darkness can disrupt the pattern. The sun is a key regulator of circadian rhythms. Blind people often have difficulty falling asleep or waking up during “normal” hours because they don’t receive the usual light cues. 

The time people choose to sleep or wake up varies significantly. This preference can also be called morningness or evenness. People are classified into two chronotypes based on their sleeping habits: the morning type (also called “larks”) and the evening type (also called “owls”). The morning type is more likely to prefer to sleep early and get up earlier and to perform better during the first half of the day. Sleep habits are associated with CLOCK gene variations, which are one of the major regulators of circadian rhythm. This would indicate that morningness or eveningness has a genetic component. 

The brain’s response to light signals 

Sleep is affected by the response of the brain to light signals. 

• The suprachiasmatic (SCN) nucleus is the master clock of the body. Light signals are sent to this cluster of nerves located in the hypothalamus, in the middle of the brain. 
• The name of this nerve cluster comes from its position, just above the optic chiasm. This is a major junction where nerves transmit information about light coming from the eyes. 
• As the sun sets, the SCN signals the pineal gland to release the hormone melatonin. The pineal gland is named so because it looks like a pinecone. 
• Melatonin may act as a hormone that sets the body’s internal clock. The longer someone is in darkness, the longer they will secrete melatonin. Staying in bright light can reduce the secretion. Melatonin may also trigger a desire to sleep. 

Sleep Cycles 

Sleep is divided into REM and non-REM sleep. These two states alternate in cycles, and they reflect different levels of brain cell activity. 

Non-Rapid Eye Movement Sleep (Non-REM Sleep): 

Quiet sleep (also called NREM or non-REM sleep) is another name for this type of sleep. Non-REM sleep is classified into three stages: 

• N1 (light sleep) 
• N2 (also known as true sleep) 
• N3 (deep “slow-wave” or delta sleep) 

As the stages descend, awakening becomes increasingly difficult. NREM sleep is unknown in the brain. Deep sleep may depend on a balance of hormones. This includes growth hormones and stress hormones. 

Rapid Eye Movement Sleep (REM): 

During REM, the brain is very active. In babies, this stage is known as active sleep. In REM sleep, the most vivid dreams are experienced. In REM, the brain activity is similar to that of waking up, but muscles are immobilized. This prevents people from acting out their dreams. The only muscles that are not immobilized in REM sleep are the eye muscles. It is possible that REM sleep is essential for daily mood regulation and learning. Sleep-deprived people’s brains have to work harder than they do when well-rested. 

The REM/Non-REM Cycle: 

This is the general pattern of sleep cycles between active (REM) and quiet (non-REM). 

• After 90 minutes of non-REM sleep, the eyes begin to move rapidly behind the closed lids. This is REM sleep. 
• As you sleep, the non-REM and REM cycles repeat. 
• Each cycle sees the non-REM sleep becoming lighter and the REM sleep becoming longer. It can last from a few moments early in the sleep episode to an hour or more at the end. 

Causes of temporary sleepiness: insomnia is often caused by a reaction to stress or change. This can be short-term (several weeks) or transient (several days) in nature. Sometimes this condition is called adjustment sleep disorder. 

A major or traumatic incident such as: 

• An acute illness 
• Accident or surgery 
• Loss of a loved-one
• Job Loss 

Temporary insomnia may also be caused by a minor event such as: 

• Extreme weather 
• Exam stress and workplace problems 
• Traveling, especially across time zones 

Normal sleep usually returns after the condition has resolved, the person has recovered from an event, or the person has adapted to the new environment. If sleepiness is affecting your ability to function or has lasted for several weeks, you should seek treatment. Stress can affect people differently. Even in the most stressful of situations, some people do not experience insomnia, while others can suffer insomnia even when under mild stress. 

Female hormonal fluctuations 

Over the course of a woman’s lifetime, fluctuations in female hormones are a significant factor in her insomnia. This temporary insomnia can occur when progesterone is a sleep promoter. This hormone’s levels plummet during menstruation, causing insomnia. Women may sleep more than usual when progesterone levels increase during ovulation. 

• Pregnancy. The changes in progesterone during the first and last trimesters can cause sleep disturbances. 
• The menopause. Sleep problems can occur during the transition from perimenopause to menopause, when hormone levels fluctuate intensely. Hot flashes, night sweats, and sudden awakenings are all possible side effects of menopause. 

Jet Lag 

Traveling across time zones by plane can cause temporary insomnia. For each time zone that you cross on a long flight, it is common to need a day for adjustment. Traveling to a time zone earlier in the west from the east is less disruptive than the opposite. This is because it’s easier to extend a circadian cycle than shorten one. 

Effects of light and other environmental disturbances 

Sleeplessness can be caused by light, noise, and uncomfortably warm temperatures. Too much or too little light, depending on the time of day, can cause sleeplessness. 

• Too Much Light at Night The biological circadian clock of a person is activated by daylight, and bright artificial lighting maintains wakefulness. 
• Sleep disturbances are linked to inadequate light exposure during the day. Sleep disturbances may be related to insufficient light exposure during the day. 

Other Causes of Temporary Sleeplessness 

Caffeine 

Caffeine can be a stimulant that interferes with sleep. 

Nicotine 

Nicotine can also be a stimulant. However, quitting smoking may cause temporary insomnia. 

Sleeping habits of a partner 

Snoring and other sleep habits of a partner can disrupt your own sleep. 

Medications 

Many common medications can cause insomnia, including those that are available over-the-counter and contain decongestants or caffeine. Consult your doctor or pharmacist if you suspect that your medication is causing sleeplessness.
