It is a frustrating experience that happens every night. A person feels physically tired with no energy and difficulty in sleeping. Insomnia not only includes difficulty in falling asleep but a person wakes up frequently at night. Moreover, one wakes up too early in the morning and feels the need to have more rest.
Insomnia affects millions worldwide and is becoming more common with time. Modern lifestyles involve increasing stress levels and disturbed mental health. Thus, it is important to understand what can cause insomnia when you are worn out is the first step towards fixing your sleep patterns.
What is Insomnia?
Insomnia is a sleep disorder that involves difficulty falling asleep and staying asleep. It is also difficult to sleep even when you have the chance to sleep. This can be short-term (acute) or long-term (chronic) and may last weeks or even months.
People experiencing insomnia report the following things:
- Trouble falling asleep
- Frequent nighttime awakenings
- Early morning waking
- Daytime fatigue and poor concentration
The insomnia does not always occur because you are not tired. Therefore, many people with insomnia feel exhausted and are still unable to sleep. This can be due to different psychological and physical health factors.
Mental Health and an Overactive Mind
Anxiety and Racing Thoughts
One of the most common causes of insomnia is anxiety. When a person’s mind constantly replays conversations, and stress about the future and everyday responsibilities then the mind stays alert. This is what prevents your body from relaxing and getting the required sleep.
It is not about whether the person has less or more anxiety because irrespective of that it becomes difficult to fall asleep.
Depression and Emotional Stress
Depression can also contribute to insomnia. If a person constantly thinks negatively and is in emotional distress that also disturbs the normal sleep cycle. Some people with depression experience early-morning awakenings, while others struggle to fall asleep at all.
Stress and Lifestyle Pressures
Chronic Stress
Work pressure, relationship worries, and personal responsibilities can all increase cortisol levels. High cortisol levels at night disturb the natural sleep-wake cycle such as they keep your brain active when it should be taking a rest.
Chronic stress is a major contributor to ongoing insomnia. Individuals who deal with demanding schedules and irregular working hours usually face it.
Poor Work-Life Balance
Many Australians work long hours or manage multiple commitments. They often blend work and personal life due to remote work. Without clear boundaries, the brain struggles to recognise when it’s time to rest. It further leads to difficulty sleeping even when exhausted.
Screen Time and Technology Use
Blue Light Exposure
Phones, tablets, laptops, and TVs emit blue light, which suppresses melatonin, the hormone responsible for sleep. If you use screens close to bedtime it sends a signal to the brain that it’s still daytime and delays sleep.
Mental Stimulation Before Bed
It is not only the light exposure but also people who consume content such as news or check their emails frequently that keep their minds alert. This mental stimulation before bed worsens insomnia, even if the body is ready for sleep.
Irregular Sleep Schedules
Inconsistent Bedtimes
Going to bed and waking up at different times each day confuses your internal body clock, also known as the circadian rhythm. When you disrupt the routine, your body may feel tired but not sleepy at the right time.
Shift Work and Time Zone Changes
Shift workers and individuals who frequently change schedules are at higher risk of insomnia. Night shifts or rotating shifts can prevent the brain from developing a consistent sleep routine.
Caffeine, Alcohol, and Diet Choices
Caffeine Sensitivity
Caffeine can remain in the body for up to eight hours. Even afternoon coffee or energy drinks can interfere with sleep, especially in people sensitive to stimulants.
Alcohol and Sleep Quality
Alcohol might make you feel sleepy at first, but it messes with your deeper sleep later on. You end up with choppy rest, waking up a bunch, which can make insomnia worse
Heavy or Late Meals
Eating big or spicy meals right before bed can lead to discomfort, heartburn, or indigestion, keeping you awake even if you’re wiped out.
Physical Health Conditions
Chronic Pain
Things like arthritis, back pain, migraines, or fibromyalgia can wreck your sleep. The pain keeps your nerves firing, making it tough to stay asleep.
Hormonal Changes
Hormone shifts from menopause, thyroid issues, or other gland problems can throw off your sleep. Night sweats, hot flashes, and mood swings often make insomnia worse.
Sleep Disorders
Other sleep-related conditions such as sleep apnea or restless legs syndrome may coexist with insomnia. These disorders interrupt sleep repeatedly, leaving you exhausted but unable to rest properly.
Poor Sleep Environment
Noise and Light
Even small noises or bits of light can mess with sleep, especially if you’re a light sleeper. Street sounds, house creaks, or glow from outside can stop you from getting deep rest.
Temperature and Comfort
An uncomfortable mattress, unsuitable pillows, or a room that’s too hot or cold can all contribute to insomnia. Physical discomfort may keep your body tired but alert.
Behavioral Habits That Worsen Insomnia
Napping During the Day
Long or late afternoon naps can reduce sleep pressure at night. The naps may seem helpful and make you feel less exhausted but they often worsen insomnia over time.
Clock-Watching
Peeking at the clock all night ramps up your stress and frustration, making it tougher to drift off. It just builds bad habits around sleep.
The Role of Cognitive Hyperarousal
Insomnia often comes from your brain staying way too wired. Even if your body’s exhausted, your mind’s racing in problem-solving overdrive and blocks sleep.
That’s why the best ideas or biggest worries hit you right at bedtime. Skip a good mental wind-down, and your brain just can’t switch off.
When Insomnia Becomes Chronic
Occasional sleepless nights are normal but chronic insomnia occurs when sleep difficulties become longer than three months. Chronic insomnia can affect:
- Mood and emotional regulation
- Memory and concentration
- Immune function
- Overall quality of life
At this stage, professional support may be necessary to identify underlying causes and develop effective treatment strategies.

Frequently Asked Questions (FAQ’s)
Why do I feel exhausted but still can’t fall asleep?
Feeling tired but unable to sleep is a common sign of insomnia. This usually happens when your mind is overstimulated due to stress, anxiety, or racing thoughts. Even though your body is fatigued, mental alertness can prevent your brain from entering sleep mode.
Can anxiety cause insomnia even when I’m very tired?
Yes, anxiety is one of the leading causes of insomnia. Ongoing worry or overthinking activates the nervous system, making it difficult to relax at night. This can lead to trouble falling asleep or frequent awakenings despite extreme tiredness.
Does screen time before bed make insomnia worse?
Absolutely. Exposure to blue light from phones, tablets, and computers suppresses melatonin production, the hormone responsible for sleep. Late-night screen use can delay sleep onset and worsen insomnia, even if you feel physically exhausted.
How long does insomnia need to last before it becomes a serious problem?
Insomnia is considered chronic if it occurs at least three nights per week for three months or longer. Chronic insomnia can affect mental health, concentration, mood, and overall quality of life, and may require professional support.
