Chronic sleep deprivation is a condition where a person experiences insufficient sleep or sleeplessness over an extended period of time, usually lasting for three months or longer. It can be caused by various lifestyle, work, and environmental factors, as well as sleep disorders and other chronic medical conditions. Chronic sleep deprivation can have negative impacts on both physical and mental health, including:

• Physical health: Chronic sleep deprivation is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, and obesity. It can also weaken the immune system, making individuals more susceptible to infections and reducing the immune response to vaccination.

• Mental health: Chronic sleep deprivation can cause or worsen mental health problems, including depression, anxiety, and irritability. It can also affect cognitive function, including memory, concentration, and reaction times.

Symptoms of chronic sleep deprivation can include excessive daytime sleepiness, irritability, difficulty concentrating, and poor memory. Treatment for chronic sleep deprivation depends on the underlying cause and may include lifestyle changes, medication, or therapy.
