What You'll Learn
Sleep disorders
Constant sleepiness can be a symptom of a sleep disorder or another underlying medical condition. Sleep disorders are characterised by the disruption of a person's ability to fall asleep or stay asleep, or they may cause odd behaviours during sleep, such as sleepwalking.
There are several types of sleep disorders that can cause EDS, including:
- Sleep apnea: This disorder causes loud snoring, gasping, choking, pauses in breathing, and sudden awakenings. People with sleep apnea may repeatedly stop breathing long enough to interfere with sleep and temporarily decrease their oxygen supply.
- Restless legs syndrome (RLS): RLS causes an irresistible urge to move the legs while lying down.
- Insomnia: Insomnia makes it difficult to fall asleep or stay asleep, and sleep quality may be poor, leaving people feeling unrefreshed when they wake up.
- Narcolepsy: A form of hypersomnia, narcolepsy causes abrupt sleep attacks that can last less than an hour. People with narcolepsy may fall asleep suddenly in the middle of an activity, such as a conversation or during a meal.
- Idiopathic hypersomnia: This disorder is characterised by excessive night-time sleeping and the need for naps during the day. People with hypersomnia may sleep for 11 hours or more but still feel sleepy and have trouble staying awake during the day.
Other Causes of Constant Sleepiness
In addition to sleep disorders, constant sleepiness can also be caused by various other factors, including:
- Lifestyle factors: Shift work, a sedentary lifestyle, and excessive caffeine intake can all contribute to sleep disruption and fatigue.
- Medical conditions: Chronic pain, hypothyroidism, oesophageal reflux, nocturnal asthma, and other conditions can disrupt sleep.
- Mental health: Depression and anxiety can impact sleep patterns and contribute to daytime sleepiness.
- Medications: Certain medications, such as steroids, blood pressure medications, antidepressants, and tranquillisers, can cause insomnia or increased tiredness as side effects.
- Diet: A diet high in ultra-processed foods and added sugar can impair sleep and lead to fatigue. Nutritional deficiencies can also contribute to constant sleepiness.
It is important to note that constant sleepiness is not normal, and if you are experiencing frequent fatigue, it is recommended to consult a healthcare professional to identify and address any underlying causes.

Shift work
Symptoms of SWSD include insomnia, hypersomnia, difficulty concentrating, lack of energy, decreased alertness, and poor mood. These symptoms can have a significant impact on work performance, with people with SWSD struggling to concentrate, pay attention, and remember things. This can lead to higher rates of absenteeism and accidents. People with SWSD are also at a higher risk of developing depression and cardiovascular disease.
The risk of developing SWSD is higher for those working night shifts or frequently rotating shifts. A study found that between 10 and 20% of night shift workers reported falling asleep during their shift. Older workers may also find it more challenging to cope with shift work, especially if they have medical conditions.
There are strategies that can help shift workers manage their sleep and reduce the risk of developing SWSD. These include maintaining a consistent sleep-wake schedule, even on days off, and creating a dark and peaceful environment for sleep during the day. Shift workers should also limit the number of consecutive night shifts and ensure they get enough sleep on their days off. Exposure to bright light during the night shift can help improve alertness, but sunlight on the way home or before sleep should be avoided as it can disrupt sleep. Consuming caffeine at the beginning of a shift can also promote alertness, but it should be avoided later in the shift to prevent sleep disruption.
While these strategies can help, the most effective way to alleviate SWSD may be to transition to a more conventional work shift.

Lifestyle factors
Sleep Habits
Improving sleep habits is crucial. Aim for seven to nine hours of uninterrupted, high-quality sleep each night. Establish a consistent sleep schedule by going to bed and waking up at the same time daily. Avoid caffeine, electronics, and exercise close to bedtime. Additionally, create a peaceful sleep environment, addressing factors like light, noise, and mattress comfort, which can impact sleep quality.
Substance Use
Substance use, including alcohol and illegal drugs, can contribute to sleep issues. Alcohol consumption can disrupt sleep patterns and increase sleepiness. Illegal drug use, including cannabis and opiates, can affect sleep and lead to hypersomnia. It is important to moderate or avoid these substances to improve sleep patterns.
Diet and Nutrition
A balanced and nutrient-dense diet is essential. Restrictive diets that limit essential nutrients like proteins, healthy fats, and carbohydrates can lead to sleepiness and low energy levels. Ensure your diet includes a range of nutrients to support overall health and energy levels.
Physical Activity
Regular physical activity can help reduce fatigue and improve sleep. Exercising during the day can decrease overall fatigue and improve your sleep cycle. However, avoid strenuous exercise close to bedtime, as it may disrupt sleep.
Stress Management
Chronic stress can contribute to sleep issues. Practices like yoga, mindfulness, meditation, and regular exercise can help manage stress and increase energy levels. Finding healthy ways to cope with stress can improve overall sleep quality.
Sleep Disorders
Certain sleep disorders, such as narcolepsy, sleep apnea, and insomnia, can cause excessive daytime sleepiness. If you suspect you may have a sleep disorder, seek professional help at a sleep disorders clinic. Treatment options like continuous positive airway pressure (CPAP) therapy or cognitive behavioral therapy for insomnia (CBT-I) can help improve sleep quality.

Medication side effects
Over-the-Counter and Prescription Sleeping Pills
Sleeping pills, both over-the-counter and prescription, can have side effects and should not be used as a long-term solution for sleep issues. These side effects can include constipation, diarrhoea, muscle weakness, digestive problems, worsening of snoring and sleep apnea, and rebound insomnia when discontinuing the medication. Additionally, sleeping pills can cause parasomnia, a disruptive sleep disorder where individuals may walk or eat in their sleep, potentially leading to dangerous behaviours. Older adults are more susceptible to side effects like confusion, memory issues, and balance problems, increasing the risk of falls and fractures. It is advisable to explore non-drug treatments first, especially for older adults, as they may be safer and more effective in improving sleep.
Medication Interactions and Side Effects
It is important to be cautious when taking sleep medication, as it can interact with other medications or cause serious side effects. Sleeping pills may interfere with normal breathing and pose risks for individuals with certain chronic lung conditions such as asthma, emphysema, or chronic obstructive pulmonary disease (COPD). Common side effects of prescription sleeping pills include burning or tingling sensations in the extremities. Always consult a doctor before taking sleep medication to ensure it is safe and appropriate for your specific circumstances.
Allergic Reactions and Tolerance
Sleeping pills, like any medication, can trigger allergic reactions. It is important to monitor for side effects and discontinue use if necessary. Prolonged use of sleeping pills can lead to the development of tolerance, making them less effective over time. This can result in a vicious cycle where individuals feel compelled to increase the dosage to achieve the desired effect, further exacerbating the problem.
Other Medications Affecting Sleep
Various commonly prescribed medications can also impact sleep. For example, heart medications like alpha-blockers and beta-blockers can interfere with REM sleep and melatonin levels, respectively, leading to daytime sleepiness and nightmares. Cholesterol-lowering statins may cause muscle pain that disrupts sleep. Alzheimer's drugs, stimulants, asthma medications, and even cold and allergy medicines can also contribute to insomnia or sleep disturbances.
Non-Benzodiazepine Drugs and Melatonin
Non-benzodiazepine drugs, such as Zolpidem, Ambien, and Zopiclone, are frequently prescribed due to their minimal side effects and low potential for drug tolerance and addiction. Melatonin, a synthetic hormone that mimics the body's natural sleep-wake cycle, is often preferred for individuals struggling with insomnia, shift work, or seniors with sleep difficulties.
In conclusion, while medication can play a role in addressing sleep issues, it is crucial to be aware of potential side effects and interactions. Consulting a healthcare provider is essential to ensure the safe and effective use of any medication, especially when it comes to managing sleep disorders or constant sleepiness.

Underlying health conditions
Excessive sleepiness, or hypersomnia, is often a symptom of underlying health issues. While primary hypersomnia occurs without another condition causing it, secondary hypersomnia is caused by a health condition or another issue that induces extreme sleepiness.
Some of the underlying health conditions that can cause excessive sleepiness include:
- Sleep disorders, such as sleep apnea, restless legs syndrome, sleep walking, insomnia, and narcolepsy.
- Medical conditions, such as hypothyroidism (underactive thyroid gland), oesophageal reflux, nocturnal asthma, chronic pain conditions, anemia, autoimmune diseases (e.g., rheumatoid arthritis, lupus, multiple sclerosis, inflammatory bowel disease), diabetes, and heart disease.
- Mental health issues, such as depression.
- Substance use, including alcohol, recreational drugs, caffeine, and certain medications (e.g., steroids, blood pressure medications, antidepressants, sedatives, muscle relaxers, antipsychotics, and stimulants).
- Lifestyle factors, such as shift work, a sedentary lifestyle, poor sleep hygiene, diet, and dehydration.
- Infections, including COVID-19, influenza, mononucleosis, and Lyme disease.
It is important to consult a healthcare provider to identify and address the underlying causes of excessive sleepiness, as it can significantly impact daily productivity, mood, and overall health.
