The first important thing in understanding why you are so tired is to know how to differentiate between quantity and quality of sleep. Often we sleep the number of hours our bodies are supposed to need to recover, and yet we spend the day feeling sleepy and tired; while there are other nights when we sleep less but feel well-rested.

This is because rest is linked with deep sleep, something that is not always directly linked to the length of time we sleep for. For example, the number of hours you sleep is not the only thing that matters, but it's also important to respect your sleep cycles; therefore, depending on the time you go to sleep, you should calculate the time you should wake up or vice versa.

Poor quality sleep, which will impact our daily routine making us feel tired and yawning all day, can be caused by various factors. Some are external factors, while others are linked to the way we sleep.

Some of the external factors which affect the quality of our sleep are:

  • Being too hot or too cold while sleeping, which prevents us from resting well.
  • Sleeping in a noisy environment, which wakes us up several times during the night. Although we may not remember these small disturbances, they still affect the quality of our sleep.
  • Certain habits, such as sleeping with the television on, prevent you from getting proper rest.
  • Sleeping next to someone who disturbs the quality of our sleep; for example, someone who snores, who talks during their sleep or who wakes up a lot.
  • Going to bed feeling stressed, concerned or tense, could lead to a poor quality of sleep.

  • Sleeping disorders, like talking in your sleep and sleepwalking, among others.
  • Frequent insomnia.
  • Chronic Fatigue Syndrome. Which is also accompanied by other symptoms such as depression, joint pain, headaches and memory-loss.
