Sleep loss accumulates over time, meaning if you miss two hours a night for a week that’s a total of 14 hours a week! That total sleep loss is called sleep debt, or sleep deficiency. Poor sleep habits and long-term sleep debt loss will affect your health. Getting enough sleep is necessary for your mental health, physical health, quality of life, and safety.
Sleep debt or deprivation is the condition of not having enough sleep and can be acute or chronic. Sleep deficiency is broader and occurs when: -You don't get enough sleep -You sleep at the wrong time of day making you out of sync with your body's natural clock -You don't sleep well or get the different types of sleep that your body needs -You have a sleep disorder that prevents you from getting enough sleep or causes poor quality sleep
Many chronic health conditions, such as heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression can stem from sleep deficiency.
It’s a common misconception that people can learn to get by on little sleep with no negative effects. While sleep need varies from person to person, adults typically thrive on 7-9 hours a night.
