4 warning signs that your body is seriously sleep deprived

Sleep is the time for the body to rest and restore a series of biological mechanisms, from the nervous system, metabolism to immunity. When sleep deprivation is severe and prolonged, the body will send out warning signals.

When sleep deprivation is at a warning level, the body will show the following symptoms:

Slow response

One of the most common signs of severe sleep deprivation is a persistent feeling of sleepiness or fatigue during the day, accompanied by a slow reaction time. This can affect work, study, driving or communication, according to the US health website Healthline .

Lack of sleep makes us more susceptible to impatience and anger.

Because when you sleep too little, your nervous system doesn't have time to recover, leading to a decrease in the performance of the cerebral cortex with its coordination and reflex functions. At the same time, the process of clearing metabolic byproducts of nerve cells is delayed, making you easily fall into a state of fatigue.

Mood disorders

Severe sleep deprivation can also have a significant impact on mood and emotional state. If a person finds themselves frequently irritable, impatient, increasingly anxious, or feeling more depressed than usual, it could be a sign. Many studies have shown that sleep deprivation leads to increased risk of depression, anxiety, and impaired memory.

This is because prolonged sleep deprivation increases levels of the stress hormone cortisol and reduces the activity of neurotransmitters such as serotonin and dopamine. This results in hormonal and neurological imbalances.

At the same time, sleep is the stage when the brain processes emotions, removes neural waste, reorganizes and consolidates memories. When this process is interrupted, the ability to regulate emotions and cope with stress is significantly reduced.

Weight gain

When you are chronically sleep deprived, your metabolism is disrupted, leading to weight gain. Many studies show that sleep deprivation increases levels of the hormone cortisol and the hormone ghrelin, which controls hunger.

The result is a negative impact on the hormonal cycle that regulates hunger and satiety and glucose metabolism. Blood glucose is not processed effectively, causing hyperglycemia, increased visceral fat and obesity.

Facial expression

When sleep deprivation is severe, the body begins to show signs on the face. Specifically, people who lack sleep have heavy eyelids, redder eyes, larger eye bags, dark circles, pale skin, and a slightly droopy mouth.

This is a result of reduced blood circulation to the skin caused by lack of sleep. This condition slows down skin cell regeneration, increases inflammation, and dilates blood vessels under the skin, leading to dark circles and dull skin, according to Healthline .
