Top 10 Reasons for Feeling Tired, Lethargic, and Having No Energy

Feeling tired due to excessive work sometimes is normal. But, if you say, “Why am I always tired and have no energy” regularly, it’s not a good sign. Constantly feeling tired, lethargic, and out of energy is a sign of deficiencies in the body or an illness.

The causes of tiredness in females and males can be the same. Below discussed are some top reasons for this:

  1. Lack of Sleep: Sleep is essential for the body to recharge and repair itself. One feels tired, irritable, and unfocused when they don't get enough sleep.
    Establishing a consistent sleep schedule is essential to ensure getting enough rest. A person suffering from sleep-related problems such as insomnia, sleep apnoea, etc., is sure to complain, “I am always feeling tired”.
  2. Poor Diet: Dietary imbalances and nutritional deficiencies play a crucial role in the way a person feels.
    Foods high in sugar and refined carbohydrates, caffeine and alcohol intake, micronutrient deficiencies, meal timings, size, etc., should be seriously considered.
    A balanced diet with lean protein, complex carbohydrates, and healthy fats can help sustain energy levels throughout the day.
  3. Dehydration: Dehydration is among the most common causes of people wondering, “Why am I so tired all the time.” Not drinking enough water can result in bodies becoming dehydrated.
    This condition makes it harder for body organs to function correctly. Drinking water and consuming 7-8 glasses of water throughout the day are important. It is especially vital during physical activity or hot weather.
  4. Lack of Exercise: Exercise is a crucial aspect of a healthy lifestyle. It helps to boost energy levels, improve mood, and reduce stress. When we don't exercise regularly, our bodies weaken, and we may experience fatigue and lethargy.
    Incorporating regular exercise into your daily routine, even if it's just a short walk, can help boost energy levels and improve overall health.
  5. Medical Conditions: Several medical conditions can contribute to fatigue and low energy levels, including anaemia, thyroid problems, and sleep apnoea.
    If you're experiencing persistent fatigue unrelated to other causes, it's essential to speak with a healthcare professional to determine if an underlying medical condition needs to be addressed.
  6. Stress: Stress can cause physical and mental fatigue, making functioning difficult. When we're under stress, our bodies produce cortisol, disrupting sleep patterns and leaving us feeling drained.
    Stress management techniques like yoga, meditation, or deep breathing exercises, can help reduce cortisol and boost energy levels.
  7. Medications: Certain medications can also contribute to feelings of fatigue and low energy levels. Antidepressants, antihistamines, and blood pressure medications are some examples of drugs that can cause fatigue.
    If you're experiencing fatigue and taking medications, you must speak with a healthcare professional to determine if there are alternative medications or dosages that may be less likely to cause fatigue.
  8. Lack of Sunlight: Sunlight is essential for the body to produce vitamin D. This is necessary for maintaining bone health and overall well-being.
    We may experience fatigue and low energy levels when we don't get enough sunlight.
    Spending time outdoors or using a light therapy box can help increase exposure to sunlight and improve energy levels.
  9. Chronic Fatigue Syndrome: Chronic fatigue syndrome is a body disorder. The symptoms include extreme fatigues that don't improve with rest. Other symptoms of chronic fatigue syndrome may include difficulty sleeping, muscle and joint pain, and headaches.
  10. Depression: Depression can cause fatigue and lethargy. People with depression may have difficulty getting out of bed, lack energy, and always feel tired. It’s advisable to seek help from a mental health therapist in a state of depression.

How to Boost Energy and Feel Energetic?

Feeling tired and lacking energy can greatly impact your productivity and overall quality of life. If you complain once a week, “Why am I, as a female, always tired and have no energy,” it’s acceptable, but not if you say this daily. Identifying the problem is good but not enough.

Initially, you can work on some factors and get your energy levels on track. Several ways can help boost your energy levels and make you feel more energetic. Here are some tips:

  1. Get Enough Sleep: One of the most effective ways to boost your energy levels is to get enough sleep. Don’t compromise, and have 7 to 9 hours of sleep each night.
  2. Stay Hydrated: Dehydration can cause fatigue and lethargy. Keep a note to drink an ample amount of water during the entire day.
  3. Eat a Balanced Diet: Eat a diet high in fresh fruits, vegetables, whole grains, and lean protein to get the energy your body needs to function optimally.
  4. Exercise Regularly: Exercise helps increase blood flow and oxygen to the body, boosting energy levels. Make a routine to exercise for a minimum of 30 minutes daily.
  5. Manage Stress: Stress can cause fatigue and lethargy. Managing stress through yoga, meditation, or deep breathing exercises is essential.
  6. Take Breaks: Regular breaks throughout the entire day can help boost your energy levels. Stand up, stretch, and take a short walk to help increase blood flow and oxygen to your body.
  7. Get Some Sunlight: Exposure to sunlight can help regulate your body's circadian rhythm, improving sleep quality and boosting energy levels.
  8. Limit Caffeine Intake: While caffeine can temporarily boost energy, too much caffeine can cause dehydration and interfere with sleep quality. Aim to limit caffeine intake to no more than 400mg per day.

These were some helpful methods to cure your most complained problem, “Why I am always tired and have no energy.” Try to implement the above-discussed methods in your lifestyle and boost your energy.

When to Seek Medical Help?

Occasionally feeling tired or lacking energy is common and can result from various factors, including stress, lack of sleep, or a poor diet. However, if you consistently feel tired or lack energy daily, it could indicate an underlying medical condition requiring attention.

If you constantly ask yourself, “Why am I, a female, so tired all the time”, then it's time to pay attention to your body and take the necessary action. Below are some symptoms that highlight the need for medical attention:

  1. Persistent Fatigue: If you feel you are always tired, despite getting enough sleep, chances are you are suffering from underlying medical conditions like anaemia, thyroid problems, or chronic fatigue syndrome.
  2. Lack of Motivation: If you feel that you are no longer motivated to do things you usually enjoy or struggle to complete daily tasks, it could indicate depression or other mental health issues.
  3. Unexplained Weight Loss or Gain: Are you experiencing a significant weight change without any significant changes to your exercise routine or your everyday meals? If yes, then chances are that it could be related to an underlying medical condition.
  4. Difficulty in Concentrating: If you are having difficulty concentrating or remembering things, it could be a sign of a neurological condition or a sleep disorder.
  5. Chronic Pain: Chronic pain, such as headaches, back pain, or joint pain, can cause fatigue and impact daily life.
