What You'll Learn
- The amount of sleep you need varies from person to person
- Insomnia is often described as feeling tired but wired
- Excessive daytime sleepiness is a common symptom of several sleep disorders
- Physical and mental exhaustion can lead to feelings of tiredness
- Lifestyle factors such as diet, exercise, and stress can impact your energy levels
The amount of sleep you need varies from person to person
The amount of sleep a person needs is highly individualised and depends on a variety of factors. While most adults need around seven to nine hours of sleep per night, this can vary from person to person. For example, some people may need only six hours to feel rested, while others may require ten hours.
Several factors can influence how much sleep a person needs. Age is one important factor, as sleep needs change throughout a person's life. Newborns, for instance, typically require 14-17 hours of sleep per day, including naps, while teenagers need around 8-10 hours, and adults generally need 7-9 hours. As people get older, their sleep patterns and needs can also change. Older adults may find themselves sleeping more or experiencing disruptions in their sleep due to age-related changes or health conditions.
Health conditions and sleep disorders can also impact how much sleep a person needs. Conditions such as sleep apnea, restless leg syndrome, and bruxism can interfere with sleep quality and duration. Additionally, mental health disorders like depression and anxiety can contribute to daytime sleepiness and tiredness. It's important to consult a healthcare professional if you suspect a sleep disorder or underlying health condition is affecting your sleep.
Lifestyle factors, such as stress, diet, and physical activity, also play a role in determining how much sleep a person needs. High levels of stress or engaging in physically demanding activities without sufficient recovery time can lead to fatigue and increased sleep needs. On the other hand, regular exercise and stress management techniques, such as relaxation or talking therapies, can improve sleep quality and reduce the amount of sleep required.
It's worth noting that deviating from your normal sleep patterns, whether sleeping too little or too much, can disrupt your body's rhythms and increase daytime fatigue. Therefore, it's essential to prioritise consistent sleep habits and maintain a sleep schedule that works best for you.

Insomnia is often described as feeling tired but wired
Insomnia is a condition that affects a person's ability to fall asleep or stay asleep, and it can have a significant impact on their daily life. The condition is often described as feeling "tired but wired", reflecting the dual state of physical exhaustion and mental alertness that characterizes insomnia. This means that while individuals with insomnia may feel a strong desire for sleep, they find themselves unable to relax and unwind, especially in the evening.
People with insomnia often report experiencing a range of symptoms, including difficulty relaxing, constant fatigue, irritability, sleep disturbances, and difficulty concentrating. They may also have trouble falling asleep or staying asleep throughout the night, and as a result, they wake up feeling tired in the morning. This can lead to a reliance on caffeine or other stimulants to get through the day, further disrupting their sleep patterns.
The causes of insomnia are varied and can include stress, anxiety, burnout, adrenal fatigue, and other mental health conditions. Additionally, lifestyle factors such as diet, exercise, and excessive screen time can also contribute to the condition. Sleep disorders, such as narcolepsy and restless leg syndrome, can also play a role in disrupting normal sleep patterns.
Treating insomnia often involves a combination of approaches, including relaxation techniques such as deep breathing, yoga, and meditation; lifestyle adjustments such as reducing caffeine intake and improving diet; and in some cases, medication and supplements. Creating a calm and comfortable sleep environment, limiting screen time before bed, and establishing a consistent sleep schedule can also help improve sleep quality.

Excessive daytime sleepiness is a common symptom of several sleep disorders
Another sleep disorder that can cause excessive daytime sleepiness is obstructive sleep apnea (OSA). OSA is caused by a blockage of the upper airway, resulting in episodes of reduced breathing or airflow. This sleep disorder is more common in older persons and shift workers and affects around 2% to 4% of the general population, with a higher prevalence in men. People with OSA may experience excessive daytime sleepiness due to recurrent hypoxia and arousals from sleep.
Other potential causes of excessive daytime sleepiness include certain medications, medical conditions, and psychiatric disorders. For example, sedating medications such as benzodiazepines and barbiturates can cause hypersomnia. Medical conditions such as hypothyroidism, epilepsy, and multiple sclerosis can also lead to excessive daytime sleepiness. Additionally, mental states like anxiety and depression can contribute to sleep disturbances, resulting in daytime sleepiness.
It is important to note that insomnia, a common sleep disorder characterized by difficulty falling or staying asleep, can also lead to feelings of fatigue and tiredness. However, insomnia does not necessarily cause hypersomnia, and people with insomnia may struggle to take naps during the day.
Overall, excessive daytime sleepiness is a symptom that can be caused by a variety of sleep disorders, medical conditions, medications, and other factors. It is important to seek medical advice if you are experiencing persistent and unexplained excessive daytime sleepiness to identify and address any underlying causes.

Physical and mental exhaustion can lead to feelings of tiredness
Chronic stress can lead to physical and mental exhaustion, causing structural and functional changes in the brain and leading to chronic inflammation, which contributes to symptoms like fatigue. It is important to note that stress is a common denominator in both physical and mental exhaustion.
Additionally, underlying health conditions, nutrient deficiencies, inadequate hydration, obesity, and certain medications can also contribute to feelings of tiredness. For example, diets high in ultra-processed foods and added sugar can impair energy levels and harm sleep quality, resulting in fatigue.
To combat physical and mental exhaustion, self-care and mindfulness practices are essential. This includes getting enough high-quality sleep, exercising, eating a healthy diet, and staying hydrated. By addressing these factors and making necessary lifestyle changes, you can improve feelings of tiredness associated with physical and mental exhaustion.

Lifestyle factors such as diet, exercise, and stress can impact your energy levels
Lifestyle factors such as diet, exercise, and stress can have a significant impact on your energy levels. Here are some ways these factors can affect your energy and, consequently, your sleep:
Diet
The food and drinks you consume provide the fuel that your body needs to function optimally. A continuous input of nutrients and sufficient calories is necessary to perform both mental and physical activities. Without this, your body can enter a state of lethargy or low energy.
A balanced diet, rich in nutrient-dense foods, is essential for maintaining energy levels. This includes consuming adequate amounts of macronutrients (carbohydrates, fats, and protein) and certain vitamins and minerals. For example, vitamin D, vitamin B12, iron, and vitamin C have all been linked to improved energy levels.
Additionally, spacing out your meals into smaller portions throughout the day can help regulate your energy release. Eating a healthy breakfast with protein-rich foods can boost your energy levels and restore your glycogen levels, keeping your metabolism up. It is also important to stay hydrated, as dehydration can lead to lower energy levels.
Exercise
Exercising might seem counterintuitive when feeling tired, but it can actually help boost your energy levels. When you exercise, your body undergoes cellular-level changes, including an increase in the production of mitochondria, often referred to as the "powerhouses of cells." Mitochondria create fuel from the glucose in your food and the oxygen you breathe, increasing your body's overall energy supply.
Exercise also improves oxygen circulation, supporting the mitochondria's energy production and allowing your body to function more efficiently. Furthermore, exercising regularly promotes better nighttime sleep, which is crucial for feeling well-rested and energetic the next day.
Stress
Stress is an inevitable part of life, and while moderate amounts can be beneficial, chronic stress can have detrimental effects on your energy levels and overall health.
Chronic stress can lead to sustained high levels of the stress hormone, cortisol, which can cause various negative physical and mental health consequences, including fatigue. It can also increase the risk of developing depression, which is associated with decreased energy and inactivity.
Managing stress through techniques like therapy or holistic health coaching can help prevent and mitigate the impact of stress on your energy levels and overall well-being.
