The reason why you are so tired is more simple than we often say. Tiredness is in 99% of cases caused by the most simple explanation: sleep-deprivation.
We sleep less than ever before.
- Passive entertainment
From the time when electricity made it possible to lengthen the light of day effortlessly, we started going to bed at a later our. Now we sleep about 7 hours per night on average, despite the human circadian rythm is set for 9 hours of sleep, resulting in sleep deprivation.
Sleeping anything less than what you need to wake up naturally is per definition sleep deprivation.
The obvious signs of sleep deprivation are:
- Excessive sleepiness
- Daytime fatigue
But more subconscious consequences by sleeping less than what you need to wake up naturally are:
- Memory Issues
- Trouble with concentration and thinking
- Mood Changes
- Weight gain
- Low sex drive
- Risk of diabetes
- Weakened immune system
- High blood pressure
- Risk of heart disease
How Sleep Deprivation Causes Weight Gain
Sleep affects the levels of two hormones, leptin and ghrelin, which control feelings of hunger and fullness.
Leptin tells your brain that you’ve had enough to eat. Without enough sleep, your brain reduces leptin and raises ghrelin, which is an appetite stimulant. The flux of these hormones could explain nighttime snacking or why someone may overeat later in night. A lack of sleep can also contribute to weight gain by making you feel too tired to exercise.
Sleep deprivation also prompts your body to release higher levels of insulin after you eat. Insulin controls your blood sugar level. Higher insulin levels promote fat storage and increase your risk for type 2 diabetes.
How Sleep Deprivation Causes Low Sex Drive
Hormone production is dependent on your sleep. For testosterone production, you need at least three hours of uninterrupted sleep, which is about the time of your first REM episode. Waking up throughout the night could affect hormone production.
This interruption can also affect growth hormone production, especially in children and adolescents. These hormones help build muscle mass and repair cells and tissues. The pituitary gland releases growth hormones continuously, but sleep and exercise also help induce the release of this hormone.
How You Can Stop Feeling Tiredness
In modern society, where everything works around the clock and technology is keeping us hooked until late at night, enough quality sleep is very rare.
The lights and sounds of a normal city makes it practically impossible to get enough deep sleep if you don’t take necessary action to work against it.
Leaving us in a state of constant sleep deprivation and less capable of making healthy choices.
