Feeling tired can result from a variety of reasons, including not getting enough quality sleep, stress, nutritional deficiencies, underlying health conditions, dehydration, and lifestyle factors such as caffeine or alcohol consumption. Inadequate or disrupted sleep, such as from insomnia or sleep apnea, is a very common cause. Other possible causes include thyroid problems, diabetes, heart disease, and even food allergies or intolerances. Chronic stress and excessive use of electronic devices that interfere with sleep patterns can also contribute to ongoing fatigue. Ensuring regular exercise, managing stress, and addressing medical issues with a healthcare professional can help combat tiredness.
If tiredness is persistent and severe, it's advisable to consult a doctor to rule out underlying medical conditions and to get appropriate treatment tailored to the specific cause.
