Dangers Of Sleep Deprivation

Lack of sleep is no smaller matter, the dangers of sleep deprivation affects all aspects of our life and health. When we sleep well, we feel refreshed, energized, and ready to take on the world. When we don’t, we feel fatigued, sluggish, and irritable. It affects your concentration, increases your blood pressure and has severe effects on your body and mind.
