Feeling tired but unable to sleep often happens because stress, anxiety, or a busy mind keeps your body in "fight-or-flight" mode, preventing relaxation, while lifestyle factors like caffeine, screens, or poor habits disrupt your natural sleep cycle, creating a wired-yet-exhausted state. Underlying health issues, medications, or even nutrient deficiencies can also contribute, making it tough for your body and brain to switch off.
When you feel tired, it should theoretically be easy to fall asleep. Unfortunately, that's not always the case. Wanting to sleep but being unable to can happen for many reasons. Stress, anxiety, hormonal imbalances, and lifestyle factors can all disrupt your body's natural sleep cycle.
Sleep disorders: insomnia, delayed sleep phase disorder, restless legs, or sleep apnea can make falling asleep or staying asleep difficult even when exhausted. Mood disorders: depression and anxiety commonly alter sleep timing and perception of tiredness.
When sleep won't come, it's often because your body and mind are working against you. Biologically, your nervous system might still be stuck in “fight-or-flight” mode. Stress hormones like cortisol and adrenaline stay high, keeping your heart rate, metabolism, and brain alert.
Most of the time, it's better to get two hours of sleep over none. Even short naps can boost your alertness and mood. You may feel groggy after the two hours, so give yourself enough time to fully wake up before you need to be “on.”
The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
The 3-2-1 bedtime method is a simple sleep hygiene strategy: stop eating 3 hours before bed, stop working 2 hours before bed, and stop using screens (phones, tablets, TVs) 1 hour before sleep, helping your body transition to rest by reducing stimulants and digestive load for better sleep quality. A more detailed version adds 10 hours (no caffeine) and 0 (no snoozing) for a 10-3-2-1-0 rule.
The 3-3-3 rule for sleep is a technique to help manage anxiety and improve sleep quality. It involves focusing on three things you can see, three things you can hear, and moving three parts of your body.
This level of fatigue goes beyond just feeling “tired” after a busy day. You may feel physically worn down, like your body is heavy and sluggish, while your mind continues to race. Even when you try to rest, the restlessness often associated with ADHD can make it hard to relax fully.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
Some 'sleep experts' still insist that if you're awake in the night, you should just lie back and relax. They suggest there's nothing you can do to change the situation and insist there's really no need. They're still of the opinion that rest is a perfectly reasonable substitute for sleep.
Women's bodies go through many changes during perimenopause and menopause. One of them is the abrupt loss of energy or extreme lethargy referred to as Sudden Crashing Fatigue. Females experience this as a sense of “crashing out” from overwhelming tiredness and fatigue.
Insomnia is the most common type of sleep disorder and it involves problems falling asleep or staying asleep despite adequate opportunity to do so. There is no specific number of hours that defines insomnia since the amount of sleep that is enough for an individual can vary from person to person.
Relax, unwind and try meditation to help you sleep
Avoid electronic devices at least an hour before bed, as mobiles, tablets and computers all throw out blue light that stops sleep. Reading, listening to soft music or a podcast, or sleep meditation can all help if you have trouble sleeping.
Symptoms of fatigue

It's particularly important to see a doctor if you're experiencing any kind of sleep problem that's preventing you from getting the sleep your body needs.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
The 20-minute rule for ADHD is a productivity strategy to overcome task paralysis by committing to work on a task for just 20 minutes, leveraging the brain's need for dopamine and short bursts of focus, making it easier to start and build momentum, with the option to stop or continue after the timer goes off, and it's a variation of the Pomodoro Technique, adapted for ADHD's unique challenges like time blindness. It helps by reducing overwhelm, providing a clear starting point, and creating a dopamine-boosting win, even if you only work for that short period.
People with ADHD may get distracted easily, forget instructions, or have a hard time finishing tasks. Attention problems in autism often occur for a different reason. A person with autism might be so focused on one thing—like a special interest or routine—that it's hard to pay attention to anything else.
Teas for stress and anxiety relief
Yes, the Navy SEAL sleep trick (an 8-minute power nap with elevated legs) is a real technique for quick rest, popularized by former SEAL Jocko Willink, that helps improve alertness and reduce fatigue, though its effectiveness depends on individual relaxation skills and it's not a substitute for full nighttime sleep. The method involves lying down, elevating your feet above your heart (on a chair or couch), relaxing facial muscles, dropping shoulders, and clearing your mind for about 8-10 minutes to promote relaxation and blood flow, preventing grogginess.
To 100% fall asleep, focus on consistent sleep hygiene (same schedule, dark/cool room, no screens/caffeine/alcohol before bed), practice relaxation like the 4-7-8 breathing technique or progressive muscle relaxation, and if awake for 15+ mins, get up and do something calm until sleepy, rather than forcing it, to build a strong bed-sleep association.
Our circadian rhythm functions by light and dark cycles and therefore an ideal sleep time is 10pm – 6am give or take ½ an hour either way so a full 8 hours of sleep is achieved each night. Even if you are retired or not working, this is an essential component of good sleeping habits.
In his piece, he revealed that through his years of research, he's found that rumination is the biggest thing that causes poor sleep. He says that being worried about something at night has affected his own ability to fall asleep.
The military sleep method involves the following steps: Breathe deeply: Close your eyes and focus on your breathing. Take slow, deep breaths. Relax your face: Slowly relax all the muscles in your face, starting from your forehead and then moving downward over your cheeks, mouth, and jaw.
