Being sleepy during the day is probably one of the most widespread results of broken sleep. The constant awakenings at night prevent the body from obtaining deep and restful sleep. Consequently, you can get up unrefreshed despite 7-8 hours in bed. The result of this continuous exhaustion may be a decrease in productivity, the experience of exhaustion in performing daily activities, and overreliance on caffeine to remain awake.

Sleep contributes to the brain functions, particularly the memory and concentration. Interrupted sleep breaks the normal processes of information processing and storage in the brain. Individuals who have disturbed sleep regularly have problems focusing their attention and retention and have slow responses. In the long term, it may have an impact on the work performance, learning capacity, and decision-making, exposing the risk of making mistakes and accidents.

Disturbed sleep may impose additional stress on the heart. The constant awakening provokes stress hormones like cortisol, and it can result in high blood pressure and heart rate at night. Broken sleep on a long-term basis has been associated with increased vulnerability to heart disease, hypertension and irregular heartbeat. A good cardiovascular system is achieved through healthy sleeping cognisance.

Sleep has been shown to assist the immune system in combating infections and keeping the body in good health. Poor sleep dispels the generation of immune cells and antibodies. This follows that individuals who do not have healthy sleep patterns will become ill more frequently, slow down when they are unwell and experience general exhaustion. With time, weak immunity may make one susceptible to infections and long-term health complications.

Sleep deprivation is not only a problem in terms of the physical being but also affects the emotional being. Not having a constant sleep may result in irritability and mood oscillations, anxiety, and lack of motivation. With time, consistent sleep disturbance can become a risk factor for depression and stress-related disorders. A lack of enough continuous rest for the mind makes emotional resilience weak.
