Sleep-Deprivation Is ACTUALLY Ruining Your Life.
It's making you sick- After just one night of skimping on sleep, you'll experience changes in mood, headache and hormone imbalances. One week of sleeping less than six hours a night may result in changes to more than 700 genes. Ongoing insufficient sleep is linked with a list of diseases including heart disease, diabetes, depression, early death and a higher risk for Alzheimer's, Parkinson's, stroke, some cancers and multiple sclerosis.
It's making you fat- Not getting enough sleep also contributes to gaining weight. After a night of insufficient sleep, people have higher levels of the hunger hormone and a decreased level of the fullness hormone. When people don’t get enough sleep, they tend to want high-calorie carbs and don’t have the impulse control to turn down a piece of cake.
It's making you stupid- Lack of sleep can slow down your thinking, impair your memory, concentration, and judgment, decision-making and impede learning. During sleep your brain is busy processing information, consolidating memories, making connections and clearing out toxins. When you are asleep, your brain regenerates itself and not having adequate time to do this could potentially accelerate neurodegenerative diseases. Not getting enough sleep can actually shrink your brain.
The anatomy of sleep- Generally everyone needs seven to nine hours sleep a night for their brain and body to perform best, as well as the quality of your sleep, is, too. Several times during the night, your brain cycles through different stages of sleep, which determine the quality of your sleep. After an initial five to ten minutes in stage one, your brain moves into a deeper stage two, and over the next hour it goes to stages three and four, in which the electrical activity slows way down.
