Risk Groups and Treatment Tips For Insomnia

Insomnia is a sleep disorder that regularly affects millions of people worldwide. In short, individuals with insomnia find it difficult to fall asleep or stay asleep.

Insomnia commonly leads to daytime sleepiness, lethargy, and a general feeling of being unwell, both mentally and physically. Mood swings, irritability, and anxiety are common associated symptoms.

Insomnia is commonly separated into three types:

  •  Transient insomnia – occurs when symptoms last up to three nights.
  •  Acute insomnia – also called short-term insomnia. Symptoms persist for several weeks.
  • Chronic insomnia – this type lasts for months, and sometimes years. According to the National Institutes of Health, the majority of chronic insomnia cases are side effects resulting from another primary problem.

 

Causes of Insomnia 

Insomnia can be caused by physical and psychological factors. There is sometimes an underlying medical condition that causes chronic insomnia, while transient insomnia may be due to a recent event or occurrence. Insomnia is commonly caused by:

  • Disruptions in circadian rhythm – jet lag, job shift changes, high altitudes, environmental noise, extreme heat or cold.
  • Psychological issues – bipolar disorder, depression, anxiety disorders, or psychotic disorders.
  • Medical conditions – chronic pain, chronic fatigue syndrome, congestive heart failure, angina, acid-reflux disease (GERD), chronic obstructive pulmonary disease, asthma, sleep apnea, Parkinson’s and Alzheimer’s diseases, hyperthyroidism, arthritis, brain lesions, tumors, stroke.
  • Hormones – estrogen, hormone shifts during menstruation.
  • Other factors – sleeping next to a snoring partner, parasites, genetic conditions, overactive mind, pregnancy.

 

Risk factors

Insomnia can affect people of any age; it is more common in adult females than adult males. It can undermine school and work performance, as well as contributing to obesity, anxiety, depression, irritability, concentration problems, memory problems, poor immune system function, and reduced reaction time.
Some people are more likely to experience insomnia. These include:

  •  travelers, particularly through multiple time zones
  • shift workers with frequent changes in shifts (day vs. night)
  •  the elderly
  • users of illegal drugs
  • adolescent or young adult students
  • pregnant women
  •  menopausal women
  • those with mental health disorders

 

Signs and Symptoms 

Insomnia itself may be a symptom of an underlying medical condition. However, there are many signs and symptoms that are associated with insomnia:

  • Difficulty falling asleep at night.
  •  Waking during the night.
  •  Waking earlier than desired.
  • Still feeling tired after a night’s sleep.
  • Daytime fatigue or sleepiness.
  • Irritability, depression, or anxiety.
  • Poor concentration and focus.
  • Being uncoordinated, an increase in errors or accidents.
  • Tension headaches (feels like a tight band around head).
  • Difficulty socializing.
  • Gastrointestinal symptoms.
  • Worrying about sleeping.

 

Sleep deprivation can cause other symptoms. The afflicted person may wake up not feeling fully awake and refreshed, and may have a sensation of tiredness and sleepiness throughout the day.

Having problems concentrating and focusing on tasks is common for people with insomnia. According to the National Heart, Lung, and Blood Institute, 20 percent of non-alcohol related car crash injuries are caused by driver sleepiness.

 

Treatment Tips

Good sleep hygiene, including avoiding electronics before bed, can help treat insomnia.

Some types of insomnia resolve when the underlying cause is treated or wears off. In general, insomnia treatment focuses on determining the cause. Once identified, this underlying cause can be properly treated or corrected.

In addition to treating the underlying cause of insomnia, both medical and non-pharmacological (behavioural) treatments may be used as therapies.

Non-pharmacological approaches include cognitive behaviorlal therapy (CBT) in one-on-one counseling sessions or group therapy. Medical treatments for insomnia include:

  • prescription sleeping pills
  • antidepressants
  • sleep aids available over-the-counter
  • antihistamines
  • melatonin
  •  ramelteon

Home remedies for insomnia include:

  • Improving “sleep hygiene”: Not sleeping too much or too little, exercising daily, not forcing sleep, maintaining a regular sleep schedule, avoiding caffeine at night, avoiding smoking, avoiding going to bed hungry, and ensuring a comfortable sleeping environment.
  • Using relaxation techniques: Examples include meditation and muscle relaxation.
  •  Stimulus control therapy – only go to bed when sleepy. Avoid watching TV, reading, eating, or worrying in bed. Set an alarm for the same time every morning (even weekends) and avoid long daytime naps.
  • Sleep restriction: Decreasing the time spent in bed and partially depriving the body of sleep can increase tiredness, ready for the next night.
