Feeling tired despite sleeping a lot often points to poor sleep quality, not quantity, caused by lifestyle factors (stress, diet, alcohol, inactivity) or underlying issues like sleep apnea, depression, thyroid problems, vitamin deficiencies, or medication side effects, all requiring a doctor to diagnose the root cause.
Sleeping excessively yet still feeling drained and unable to concentrate often points to underlying issues like sleep disorders (eg, sleep apnea), hormonal imbalances (like thyroid dysfunction), or chronic fatigue syndrome. Nutritional deficiencies, depression, or anemia can also play a role.
Some treatable sleep disorders, such as hypersomnia, sleep apnea, and narcolepsy, also result in excessive daytime fatigue, even if someone slept plenty the night before. “If sleep is [chronically] unrefreshing, you need a medical workup” to rule out these and other conditions, says Dr.
Idiopathic hypersomnia is a condition that causes people to be very sleepy during the day even after a full night of sleep. People with the condition have trouble waking up from sleep. They also may wake up confused and disoriented.
“In many cases, patients just aren't getting enough sleep—6 hours or less on most days,” says Nessreen Rizvi, M.D., an internal medicine physician at Henry Ford Health. “But there are a number of other things that may be at play, including nutrient deficiencies, undiagnosed infections, even your smartphone.”
Vitamin B12 Deficiency: A Rare Cause of Excessive Daytime Sleepiness | Journal of Clinical Sleep Medicine.
Spending excessive time in bed may be a sign of an underlying medical condition, such as depression. Depression is a mood disorder that has many symptoms, including decreased interest in activities or other people, weight changes, trouble sleeping, and fatigue.
Fatigue red flags signal potentially serious issues beyond normal tiredness, including unexplained weight loss, persistent fever, night sweats, shortness of breath, chest pain, severe headaches, confusion, or new neurological/joint problems alongside exhaustion. Other signs include fatigue worsening with activity, significant cognitive/mood changes, or lack of energy despite rest, suggesting conditions like infection, autoimmune disease, heart problems, cancer, or mental health issues, warranting prompt medical evaluation.
Vitamin B12 and folate perform several important functions in the body, including keeping the nervous system healthy. A deficiency in either of these vitamins can cause a wide range of problems, including: extreme tiredness. a lack of energy.
The four Ps are problem solving, planning, prioritising and pacing. The aim is to think of the four Ps at the beginning of each day or week to help you manage your energy levels.
Fatigue becomes worrisome when it lasts over two weeks despite rest, significantly impacts daily activities, comes on suddenly without clear cause, or accompanies "red flag" symptoms like unexplained weight loss, shortness of breath, fever, severe pain, unusual bleeding, or heart issues, signaling a need for prompt medical attention for potential underlying conditions like anemia, diabetes, sleep apnea, thyroid problems, or infections.
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.
Bed rotting can sometimes be a symptom of depression, but not everyone who does this is depressed. They could just be doing it to rest and recharge.
Apathy is when you lack motivation to do things or just don't care much about what's going on around you. Apathy can be a symptom of mental health problems, Parkinson's disease, or Alzheimer's disease. It often lasts a long time. You may lack the desire to do anything that involves thinking or your emotions.
Narcolepsy is a condition that makes people very sleepy during the day and can cause them to fall asleep suddenly. Some people also have other symptoms, such as muscle weakness when they feel strong emotions. The symptoms can have serious effects on daily life.
Vitamin B12
Vitamin B12 helps make your DNA, produce red blood cells and protect your nervous system. “Red blood cells transport oxygen through your body,” explained Dr. Shah. “So, when you don't have enough B12 to produce red blood cells, oxygen doesn't get transported to your cells, which leaves you feeling tired.”
While every organ in the body is affected by poor sleep, the brain takes the biggest hit, showing signs of dysfunction faster than any other system. Over time, the heart, liver, and immune system also begin to show stress, which can increase your risk of chronic illness.
The hand test can help you figure out if a mattress is too soft or firm. While lying flat on your back, attempt to slip one hand under your lumbar curve (that's the lower back, where the spine naturally curves). If it slides underneath easily, the mattress might be too firm.
Bed rotting is a recurring behavioural pattern, where someone stays in bed during waking hours for large periods of time. This can range from most of the day to an entire week without engaging in daily activities and chores.
Simply put, microsleep is when you fall asleep for a period of several seconds. As the name implies, microsleep occurs so quickly that people who have an episode might not even realize they have fallen asleep. Microsleep can occur at any time of day, not just at night.
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.
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.
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.
A Complete Blood Count (CBC) is a comprehensive blood test that measures various components of your blood, including red blood cells, white blood cells, and platelets. This test is crucial for detecting conditions like anemia, which can cause extreme fatigue.
Physical symptoms: reduced activity, low energy, tiredness, decreased physical endurance, increased effort to do physical tasks, general weakness, heaviness, slowness or sluggishness, nonrestorative sleep, and sleepiness.
