A sluggish thyroid may lead to chronic exhaustion.

If you are living with a sluggish thyroid, which is medically known as hypothyroidism, it may contribute to chronic exhaustion. Constant fatigue and low energy levels are seen as the major symptoms of hyperthyroidism. It is believed that when the thyroid is underactive, it may also slow down a wide range of bodily processes, resulting in fatigue and a feeling of being rundown. Unfortunately, many people living with it are unaware, worsening the condition and its associated symptoms. A plethora of medications are available to treat it, helping you bring your thyroid levels to normal.

Undergoing a simple blood test will help determine if this is the cause or not. If this is the culprit behind your chronic exhaustion, getting on medication can be a game-changer.

You are going beyond the limit while drinking.

While many people connect alcohol to relaxation, taking in large amounts on a daily basis can affect your sleep cycle greatly. Given that alcohol is a depressant, it may help you fall asleep quickly. However,  you will be getting less rapid eye movement sleep, which stands as the crucial restorative sleep your body needs to function optimally. 

If you are taking alcohol, take it along with dinner and at least one to two hours before going to bed. Be sure to stick to a limit; otherwise, you may face disruptions in your sleep quality. In addition to affecting your quality of sleep, it also interferes with your breathing pattern at night.

Caffeine may be a silent culprit.

It may seem counterintuitive, but loading caffeine too much in the body can also lead to chronic exhaustion directly or indirectly. While many believe that caffeine keeps you awake and energetic throughout the day, consuming excessive amounts of caffeine through coffee, soda, or other sources can disrupt your sleep. Try to cut back on your caffeine intake and drink it in moderation to avoid unwanted consequences. The body’s ability to digest caffeine shrinks as you age, preserving its effects in the body for longer.

Exercise is not on your day-to-day to-do list.

Engaging in physical activity daily for at least 30 to 40 minutes can help you stay active throughout the day.  Getting enough exercise increases deep, slow-wave sleep, which decreases fatigue and enhances recovery. If you are exercising more than recommended, it may even cause you to feel fatigued easily and increase your stress levels. 

Look after hydration.

Drinking 2 to 3 litres is considered ideal for healthy adults. If you don’t drink enough water, this makes your organs work harder than usual to pump blood and carry nutrients throughout the body. In order to lessen this stress on your body, try to drink enough water daily to keep your health in check and free from most diseases. Dehydration elevates your chances of developing a wide range of complications. If you are not able to drink enough water, try to include water-rich fruits and vegetables such as peaches, melon, and grapes.

Don’t compromise your daily sleep. 

Getting enough sleep daily is the key to optimal health. In today’s culture, sleep is often overlooked in the pursuit of success, increasing the risk of developing a wide range of health complications. In order to keep your mental and physical health optimal, don’t compromise your daily sleep because it is a primary requirement of your body. If you face trouble while falling asleep, seeing a doctor can be helpful in fixing the underlying cause.

Maybe you have anemia.

One of the major causes of fatigue or chronic exhaustion in females is anemia. However, it can affect people of all genders, but it appears to be more prevalent in females for several reasons. To maintain your iron levels, start incorporating green leafy vegetables and various types of meat into your diet.  Your medical professional may carry out a blood test to check your iron levels. If you are iron-deficient, the doctor will create a plan to help you increase iron levels.

Going through a mental health condition. 

If you are experiencing symptoms of any mental illness, seeing a doctor is important. If left untreated, it may bring about other complications and may make your daily life more challenging. If you are feeling sad, mentally exhausted, panicked, frightened, or nervous, without any apparent cause, it serves as a sign of mental illness. A mental health condition can be more draining and distressing for your body than you think, resulting in symptoms like exhaustion and tiredness. When you are in a fight-or-flight mode, your heart functions harder to pump blood, raising blood pressure and putting the entire system on high alert. 

Conclusion:

Feeling lethargic or fatigued at times is normal, especially when you have used your body and mind rigorously to accomplish a task or achieve something. However, experiencing it daily without any apparent cause is a red signal and begins to affect other aspects of your life; it raises serious questions about your health. If you have been experiencing exhaustion for the past 6 months, even after following a healthy diet or getting enough sleep, consult a doctor to find out the cause of the problem. Chronic tiredness increases your chances of several complications later in life and puts extra strain on the body. The doctor will develop a care plan after a thorough analysis of your health.

FAQs:

1. When should I be concerned about constant tiredness? 

When your tiredness persists for several weeks, starts to interfere with your daily life, and brings on other symptoms such as shortness of breath, weight loss, or chest pain, it becomes increasingly important to see a doctor. Feeling fatigued even after getting adequate sleep demands medical attention. 

2. Can vitamin deficiencies cause tiredness? 

Yes, you may develop tiredness due to a deficiency of vitamins.  Many vitamins carry out many vital functions in energy production and overall vitality, and a deficiency of them can result in exhaustion. 

3. Does stress or anxiety make you feel tired all the time?

Yes, both stress and anxiety can really contribute to feeling tired all the time. Chronic stress and anxiety often keep us in a state of constant alertness and worry, which can be mentally draining and physically exhausting. This ongoing state of heightened alertness can disturb our sleep, leaving us feeling fatigued and low on energy. 

4. Is it normal to feel tired after sleeping 8 hours?

Waking up tired after a full night of sleep is common and okay at times. However, if you feel exhausted or lethargic daily even after a sleep of 7 to 9 hours, it raises concerns. Most healthy adults need about 7 to 8 hours of sleep daily for optimal health, but certain factors can result in daytime fatigue, such as sleep quality and underlying health conditions.
