Feeling tired all the time, or experiencing chronic fatigue, can stem from a variety of physiological, psychological and lifestyle factors. According to science, here are some common reasons:
Not getting enough sleep or poor-quality sleep, can lead to chronic fatigue. Conditions like insomnia, sleep apnea, or restless leg syndrome can disrupt sleep cycles and leave you feeling tired despite spending enough time in bed.
Low levels of certain nutrients like iron (leading to anaemia), vitamin D, vitamin B12, and magnesium can cause fatigue. Inadequate water intake can also reduce energy levels, as water is essential for various body functions.
Surprisingly, a lack of physical activity can make you feel more tired. Regular exercise helps improve energy levels, endurance, and overall well-being.
Chronic stress and anxiety can drain your energy and disrupt sleep, leading to persistent fatigue. Fatigue is a common symptom of depression, where even simple daily tasks can feel exhausting.
Reduced heart function can lead to fatigue as the body isn’t getting enough oxygenated blood to maintain energy levels. Persistent infections, such as mononucleosis or post-viral fatigue, can also leave you feeling tired even after recovery.
Certain medications, such as antihistamines, antidepressants, or beta-blockers, can cause drowsiness or fatigue.
Autoimmune diseases like rheumatoid arthritis or lupus cause chronic inflammation, which can contribute to fatigue by affecting energy levels and body systems.
