Sleep problems and insomnia occur when a person has difficulty falling asleep or staying asleep, which impacts their daily activity and ability to focus.

What are sleep problems and insomnia and their symptoms?

This disorder is defined as the inability to sleep, frequent waking, or feeling that sleep is non-restorative. The condition is diagnosed when these difficulties recur three or more times per week for at least one month.

Common signs include:

Staying awake for long periods before falling asleep.
Waking up several times during the night.
Waking up very early and being unable to return to sleep.
Feeling lethargic and tired during the day despite sleeping.
Irritability and poor concentration.

Causes of Sleep Disorders

Various factors can lead to these issues, most notably:

Psychological and Environmental Factors:

Stress and pressures related to work or family.
Anxiety and depression, which can be both a cause and a symptom.
Poor habits, such as using electronic screens before bed or eating heavy meals.
Excessive caffeine and nicotine intake.

Health and Physical Conditions:

Chronic pain, such as headaches and back pain.
Lung diseases, asthma, and heart failure.
Neurological disorders such as Parkinson’s and Alzheimer’s.
Sleep apnea and restless legs syndrome.

Lifestyle Changes:

Shift work, which affects serotonin levels.
Jet lag resulting from changes in the biological clock.

Causes Specific to Women and the Elderly:

Women may experience disorders related to the menstrual cycle, pregnancy, or menopause (affecting approximately 40% of women during this stage).
Older adults tend to be light sleepers, as their biological clocks are affected and their medication use often increases.

How to Manage Sleep Problems and Insomnia

The approach to insomnia treatment varies based on severity and includes:

Natural and Behavioral Measures:

Setting fixed daily times for sleeping and waking.
Regular exercise, avoiding it in the final hours before bed.
Preparing the bedroom to be dark, quiet, and at an appropriate temperature.
Avoiding long daytime naps (should not exceed 30 minutes).
If you remain awake for more than 20 minutes, it is recommended to leave the bed and engage in a quiet activity until you feel sleepy.

Therapeutic Interventions:

Using relaxation techniques and yoga.
Hypnosis therapy via audio recordings to reduce stress.
Consulting a sleep or mental health specialist to prescribe specific medications or treat underlying conditions.

The Vicious Cycle of Insomnia

Specialists describe a state of constant anxiety about sleep as the vicious cycle of insomnia; the fear of being unable to sleep increases stress, and this stress, in turn, makes sleep more difficult. Breaking this circle requires focusing on distracting the mind from the state of wakefulness rather than over-focusing on the attempt to sleep.

When Should You Visit a Doctor?

Medical help should be sought if the following signs appear:

Sleep disturbances persist for more than a month.
Extreme fatigue that hinders the performance of daily tasks.
Loud snoring associated with shortness of breath or high blood pressure.
When the problem results from chronic pain or psychological illnesses.
