Why do I sleep the necessary hours and feel tired all day? Being always sleepy, being tired all day, and feeling fatigued can be a real problem when carrying out a routine: work, family, pending tasks, etc. When resting is not synonymous with feeling relaxed, and sleep accompanies us throughout the day, our body alerts us that something is wrong. Different causes are directly linked to sleep problems, while others present sleep as a symptom. In this FastlyHealarticle, we answer why I am always sleepy.

Why do we sleep?

Sleep is a biological necessity, essential both physically and mentally. During sleep, the body carries out a series of functions and changes in the organism: blood pressure, body temperature, heart and respiratory rate, hormone secretion, etc. We sleep so that our body and mind stay awake during the day, and precisely because of this. Therefore, for the body to achieve a correct balance, you must sleep the necessary hours and activate the body when awake. If the body does not sleep when it should, it stores this information and will try to balance this lack of sleep later, as soon as it is allowed to rest. Likewise, it is also known that if we did not let our bodies sleep, we would die.

However, being sleepy during the day is not synonymous with not having had enough sleep, but there may be several causes causing this constant feeling of rest.

Anxiety and depression

Anxiety and stress can generate significant adverse effects on human health, reducing considerably the welfare of people both personally and in their ability to perform tasks. Concern has been shown to create abnormal activation of the neurochemical systems responsible for regulating the wake-sleep cycle. This implies that the person suffering from anxiety may have problems when trying to sleep due to overexcitement. Fatigue is one of the main symptoms of anxiety, generating a circle in which fear causes fatigue, leading to anxiety. Stress hinders the normal execution of tasks, so it implies that when we finish them, we feel exhausted.

Depression is another psychological problem that can externalize physical symptoms such as fatigue, headaches, back pain, lumbar, cervical, tachycardia, etc. The person suffering from depression can experience deep tiredness throughout the day, so not only can they present emotional fatigue, but the body also feels down.

If you are wondering why you are always sleepy, think about whether you tend to suffer from frequent stress or anxiety. On the other hand, feeling tired all day is not synonymous with a person suffering from depression, although it may be related.


It is a condition that is produced by an increase in the activity of the thyroid gland, which is why it has some hormones in excess and, as a consequence, affects some functions of the body. These changes are often accompanied by both physical and psychological symptoms, such as feeling irritated, nervous, witnessing mood swings, and fatigue and irritability. In addition, it is also common for people to have hyperactivity. All these symptoms make the person sleepy during the day despite having slept enough hours at night. Hyperthyroidism can be treated differently, so we invite you to consult the full article on hyperthyroidism.

Insomnia and sleep apnea

They are one of the most common sleep disorders.

In the case of insomnia, the problem of falling asleep causes the fact of being sleepy during the day. This disorder prevents a person from sleeping for a long time for time and having issues getting to sleep. This lack of sleep can translate into problems such as concentration problems and fatigue throughout the day.

On the other hand, another disorder that can cause problems with rest is sleep apnea, which involves an interruption in breathing during sleep. This disorder is characterized by the presence of snoring when the person falls asleep, which is intensified to the point where they stop breathing for a few seconds. This stop of breathing causes the person to feel fatigued the next day because it is another reason you can always be sleepy during the day for no apparent reason. In this article, you can learn more about sleep apnea.


It is a rare disorder in which the person suffering from it feels tired throughout the day due to abnormalities in the central nervous system. Although there is no specific cause, it is believed to be hereditary. In the case of always being sleepy during the day due to narcolepsy, the explanation is in the low levels of a stimulating hormone that the brain produces, called hypocretin, whose function is based on keeping the body awake. In addition, constantly being sleepy in this case may also be related to poor regulation of sleep phases.

When to go to the doctor?

Feeling tired during the day should result from not having slept properly one day on time. Therefore, if you are always tired during the day for no apparent reason, you should see a doctor establish the cause and treat the problem. Knowing why you are always sleepy should also prompt you to visit a specialist who can end the situation. As we explained previously, sleep plays a vital role in our body, and if we do not feel we rested during the day, it can cause real headaches.

Change some lifestyle habits.

While visiting the doctor is almost mandatory when we feel that we are always sleepy, there are a series of tips to keep in mind that will help you adopt a healthy routine to sleep well and feel rested the next day.

  • Establish a routine at bedtime. We must go to sleep each day while calculating the necessary hours that we have to rest based on the time we are going to get up the next day. Remember that you should sleep 8 hours every day.
  • Do not consume stimulant products, especially drinks such as alcohol, coffee, stimulant soft drinks, etc. These will make it difficult for us to fall asleep.
  • Eat a balanced diet and do not eat copious dishes, especially before going to sleep.
  • Exercise our body . Perform physical exercise to burn energy and thus make it easier for our body to need to rest.
