13 Hidden Reasons You Feel Tired Despite Getting Enough Sleep
Dr. Wala’a Hafiz – Some may believe that sleeping for longer hours is the solution to overcoming fatigue, but getting eight hours of sleep does not always mean waking up feeling energized. Some people may feel tired, sluggish, and have difficulty concentrating despite getting enough sleep, due to simple daily habits that affect sleep quality and energy levels. According to a report published by The Guardian, doctors and experts in nutrition and sleep have revealed unexpected reasons behind persistent fatigue, noting that simple lifestyle changes can help restore vitality.
1. Poor bedroom ventilation
The quality of air inside the bedroom affects sleep quality. Keeping windows and doors closed with more than one person in the room leads to elevated carbon dioxide levels, which can reduce sleep efficiency and decrease the duration of deep sleep, in addition to raising stress hormone (cortisol) levels upon waking.
2. Low creatine stores
Creatine is not limited to athletes; it helps all body cells produce energy. Experts explain that the creatine compound contributes to the regeneration of adenosine triphosphate (ATP), the molecule responsible for storing and releasing energy. Older adults, athletes, women, and vegetarians may benefit from creatine supplements, as most natural creatine comes from meat and fish. Studies have shown that taking five grams daily may help reduce mental fatigue, improve athletic performance and mood after sleep deprivation, and increase both the duration and quality of sleep.
3. Lack of exposure to daylight
Natural sunlight helps regulate the body’s biological clock and improve sleep, while also helping to regulate blood sugar levels. Exposure to light during the day helps the body distinguish between night and day, which positively impacts energy levels.
4. Insufficient fiber intake
Not getting enough fiber can lead to fluctuations in energy levels and make you feel sluggish. Foods rich in fiber help slow down sugar absorption in the blood, providing more stable energy. Good sources include legumes, leafy vegetables, berries, whole grains, seeds, and nuts.
5. Sleeping without true rest
A person may sleep for sufficient hours but not give their mind a chance to relax due to continued busyness and productivity even during rest times. Rest does not mean only sleeping; it also includes activities such as closing your eyes, reading, stretching exercises, and spending time in nature.
6. Deficiency in polyphenols
Brain fog and difficulty concentrating may be linked to a deficiency in polyphenols, which are antioxidant compounds found in berries, strawberries, eggplant, dark chocolate, as well as tea and coffee. Studies indicate their role in improving the delivery of oxygen and nutrients to the brain and reducing mental fatigue.
7. Overthinking before bed
The brain continues to process the day’s events and store memories during the night. However, leaving certain matters unresolved can lead to waking up and thinking in the middle of the night, which raises cortisol levels and makes it harder to fall back asleep. It is recommended to write down postponed tasks and set a time to complete them before bed.
8. Eating dinner late
Eating heavy meals before sleep, especially those rich in protein and fat, can affect sleep quality because digestion raises body temperature and increases blood flow to the digestive system, while the body needs a drop in temperature to enter deep sleep.
9. Slow bowel movement
The gut is connected to the brain via the vagus nerve, and slow bowel movement can contribute to feelings of sluggishness. One study suggests that eating two kiwis daily may help improve bowel movement due to the fiber that draws water into the stool, making it softer.
10. Excessive protein intake
An overemphasis on protein can lead to reduced carbohydrate intake, causing lower energy levels, especially in active individuals. It is recommended to balance meals with vegetables, carbohydrates, and protein, adding healthy fats.
11. Not airing out the bed
Dust mite waste, scented laundry detergents, and synthetic fabrics can cause mild inflammatory responses leading to nasal congestion, itching, and frequent awakenings. Tips include washing bedding weekly, using protective covers, and leaving the bed open in the morning to air it out.
12. Prolonged sitting
The brain may interpret prolonged sitting as a sign of inactivity, which affects energy levels. Therefore, it is recommended to move for two minutes every 30 minutes and to walk after lunch to help boost activity.
13. Vitamin deficiencies
Persistent fatigue may be a sign of a health issue, such as iron deficiency, which causes physical tiredness, or vitamin B12 deficiency, which is linked to brain fog, or thyroid disorders. Therefore, it is advisable to consult a doctor and undergo necessary tests to determine the true cause of the fatigue.
