Defining Insomnia:

Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or experiencing non-restorative sleep, despite having adequate opportunity for sleep. It can manifest as transient, acute, or chronic, depending on the duration and frequency of symptoms.

Primary Causes of Insomnia:

Psychological Factors:

Stress, anxiety, and depression are common psychological factors contributing to insomnia. Racing thoughts, worries, or rumination can make it challenging to relax and fall asleep.

Lifestyle Habits:

Poor sleep hygiene, such as irregular sleep schedules, excessive screen time before bed, and consumption of stimulants like caffeine or nicotine, can disrupt sleep. Irregular work shifts or travel across time zones can disrupt the body’s natural sleep-wake cycle, leading to insomnia.

Medical Conditions:

Chronic pain conditions, gastrointestinal disorders, respiratory problems, and neurological disorders can all interfere with sleep. Hormonal imbalances, such as those occurring during menopause or thyroid disorders, may contribute to insomnia.

Secondary Causes of Insomnia:


Certain medications, such as antidepressants, stimulants, corticosteroids, and some asthma medications, can disrupt sleep patterns as a side effect.

Substance Use:

Alcohol, while initially sedating, can disrupt sleep architecture and lead to fragmented sleep patterns, worsening insomnia over time. Recreational drugs or prescription medications abused for their sedative effects can contribute to insomnia and other sleep disturbances.

Environmental Factors:

Noise Pollution:

Loud noises from traffic, construction, or household activities can disturb sleep and contribute to insomnia. Light pollution from streetlights, electronics, or illuminated alarm clocks can disrupt the body’s production of melatonin, a hormone essential for sleep regulation.


Extreme temperatures, whether too hot or too cold, can interfere with the body’s ability to maintain optimal sleep conditions, leading to insomnia.

Consequences of Insomnia:

Impaired Cognitive Function:

Insomnia can impair cognitive function, including attention, concentration, memory, and decision-making skills. Chronic sleep deprivation increases the risk of accidents, errors, and decreased productivity in both personal and professional settings.

Mood Disturbances:

Insomnia is associated with an increased risk of mood disorders, including depression and anxiety. Sleep disturbances can exacerbate existing mental health conditions and contribute to emotional dysregulation.

Physical Health Risks:

Chronic insomnia is linked to an increased risk of cardiovascular disease, obesity, diabetes, and other chronic health conditions. Sleep deprivation compromises immune function, making individuals more susceptible to infections and illnesses.

Understanding Insomnia

Insomnia, a prevalent sleep disorder affecting individuals worldwide, is characterized by persistent difficulties in falling asleep, staying asleep, or achieving restorative sleep. Its multifaceted nature encompasses a myriad of causes, including psychological factors, lifestyle habits, medical conditions, medications, substance use, and environmental influences. The consequences of insomnia extend beyond mere sleep disturbances, encompassing impaired cognitive function, mood disturbances, and increased risks to physical health. At Nadcell Clinic, we recognize the importance of comprehensively understanding insomnia to tailor effective treatments, including innovative approaches like NAD Therapy, to address underlying factors and restore restful sleep for optimal health and well-being.

Treating Insomnia with NAD Therapy:

At Nadcell Clinic, we offer a unique approach to treating insomnia through NAD Therapy, a cutting-edge treatment modality that addresses underlying cellular dysfunction and promotes overall wellness. NAD (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells and plays a crucial role in energy metabolism and cellular repair processes. NAD Therapy involves the administration of NAD precursors, such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN), to replenish NAD levels in the body.

Research in to Nad Therapy & Long Covid

Research suggests that NAD Therapy may help alleviate insomnia by improving cellular function, reducing inflammation, and promoting relaxation. By restoring balance to the body’s biochemistry, NAD Therapy can enhance sleep quality and duration, allowing individuals to experience restorative sleep and wake up feeling refreshed and rejuvenated.

Insomnia is a complex sleep disorder with multifaceted causes and consequences that can significantly impact quality of life. At Nadcell Clinic, we recognise the importance of addressing insomnia holistically and promoting restorative sleep for optimal health and well-being.
