PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Sleep deprivation may decrease production of these protective cytokines. In addition, infection-fighting antibodies and cells are reduced during periods when you don’t get enough sleep. So, your body needs sleep to fight infectious diseases.

Detailed explanation-2: -In a similar way, restricting sleep to 4 hours for one night led to the generation of inflammatory cytokinesa, which play an important role in the development of cardiovascular and metabolic disorders (Figure 2.2, arrow 2). Sleep loss is also related to a higher risk for infection.

Detailed explanation-3: -Notably, insufficient sleep has been linked to the development and management of a number of chronic diseases and conditions, including type 2 diabetes, cardiovascular disease, obesity, and depression.

Detailed explanation-4: -Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep. Stressful life events or trauma-such as the death or illness of a loved one, divorce, or a job loss-also may lead to insomnia.
