Excessive stress and sleep deprivation can cause cardiovascular issues, such as high blood pressure and heart disease.

[22]
Blood pressure, heart rate, and respiration rate will all decrease when one is relaxed. [citation needed] This means that a person's heart does not beat as fast and their breathing is shallow, helping one's body have time to rest. This will reduce the extra stress that these things can do to the body if they are over worked.

Sleep apnea (or sleep apnoea in British English; /æpˈniːə/) is a sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. Each pause in breathing, called an apnea, can last for several seconds to several minutes, and may occur 5 to 30 times or more in an hour. [4]
This depletes the body's energy more quickly and usually occurs over long periods of time, especially when these microstressors cannot be avoided (i.e. stress of living in a dangerous neighborhood). See allostatic load for further discussion of the biological process by which chronic stress may affect the body. For example, studies have found ...
During this phase, body temperature and heart rate fall, and the brain uses less energy. [12] REM sleep, also known as paradoxical sleep, represents a smaller portion of total sleep time. It is the main occasion for dreams (or nightmares ), and is associated with desynchronized and fast brain waves, eye movements, loss of muscle tone, [ 20 ...
