Sleepless nights may lead to severe health disorders
Sleep is a naturally recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli but is more easily reversed than the state of being comatose. Sleep occurs in repeating periods, in which the body alternates between two highly distinct modes known as non-REM and REM sleep. Although REM stands for “rapid eye movement”, sleep affects other brain-body functions, including virtual paralysis of the body.
During sleep, most systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems. The internal circadian clock promotes sleep daily at night. However, sleep patterns vary among individuals. In the last century, artificial light has substantially altered sleep timing in industrialized countries.
Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function.
Sleep deprivation can cause damage to your body in the short term. Over time, it can lead to chronic health problems and negatively impact your quality of life. Inadequate sleep raises your risk of accidental injury and death from all cause.
Effects of sleep deprivation on the body
Central Nervous system: Sleep deprivation leaves the brain exhausted, so it can’t perform its duties well. In children and young adults, the brain releases growth hormones during sleep. In sleeping, your body is also producing proteins that help cells repair the damage. Sleep might play an important role in the ability to regulate negative emotions in people who suffer from anxiety or depression.
Importantly, these affect-evoked PNS and CNS responses do not simply co-occur. Despite emerging links between sleep and affective brain function, the impact of sleep and sleep deprivation on the interconnected central brain and peripheral autonomic discrimination of complex social emotions remains unknown.
Immune system: Lack of sleep can affect your immune system. Studies show that people who don’t get quality sleep or enough sleep are more likely to get sick after being exposed to a virus, such as a common cold virus. Sleep deprivation may decrease the production of these protective cytokines (It uses these tools to fight off foreign substances like bacteria and viruses).
Respiratory system: Sleep deprivation can weaken your immune system, you’re more vulnerable to respiratory problems like the common cold and influenza. If you already have a chronic lung disease, sleep deprivation is likely to make it worse
Digestive system: Sleep deprivation increases production of the stress hormone cortisol. Lack of sleep lowers your levels of a hormone called leptin, which tells your brain that you’ve had enough to eat. In addition, it raises levels of a biochemical called ghrelin, which is an appetite stimulant.
Diabetes: Sleep deprivation prompts your body to release higher levels of insulin after you eat, promoting fat storage and increasing your risk of developing type 2 diabetes.
Cardo vascular system: People who don’t sleep enough are at higher risk for cardiovascular disease—regardless of age, weight, smoking and exercise habits. Over time, this can lead to higher blood pressure during the day and a greater chance of cardiovascular problems.
Effect Sex Drive: Lack of sleep lowers testosterone levels, kills your libido. Similarly, a comprehensive analysis of research found that sleep deprivation may also lower testosterone levels in women—although it’s much harder to measure—which can lead to sexual dysfunction and a reduced sex drive as well.
