Sleep deprivation is one of the main causes of lack of focus. Your brain's capacity to focus and process information suffers, making it easy to lose concentration.

Anxiety or stress might cause you to lose focus on the here and now. The brain has a mechanism for temporarily shutting down when it is overworked by stress and anxiety.

Low blood sugar might cause you to lose awareness and make it difficult to stay focused. This is because glucose is the primary fuel used by the central nervous system.

Low blood pressure can restrict blood flow to the brain, leading you to feel dizzy because the brain is deprived of oxygen. As a result, you lose focus and zone out.
