Getting enough sleep helps protect your physical and mental health, while a deficiency increases the risk of chronic diseases and various health problems.
How many hours of enough sleep are needed for good health?
The body’s need for rest varies based on age and other factors. The recommended daily hours can be broken down as follows:
- Infants (4-12 months): 12 to 16 hours (including naps).
- Toddlers (1-2 years): 11 to 14 hours (including naps).
- Preschoolers (3-5 years): 10 to 13 hours (including naps).
- Children (6-12 years): 9 to 12 hours.
- Teenagers (13-18 years): 8 to 10 hours.
- Adults: 7 hours or more per night.
Factors affecting sleep quality and duration
It is not just about the number of hours; other influencers determine how much the body benefits from rest:
- Sleep Quality: Fragmented sleep reduces the desired benefit, even if the hours are long.
- Previous Deprivation: The body’s need for rest increases if a person has experienced a lack of sleep in previous periods.
- Pregnancy: Hormonal changes and physical discomfort can negatively affect sleep quality.
- Aging: Older adults need approximately the same number of hours as other adults, but their patterns differ; sleep may be less deep, it may take longer to fall asleep, and nighttime awakenings are more frequent.
Risks of sleep deficiency and benefits of following recommended durations
Obtaining enough sleep in children is linked to improved memory, stronger concentration, behavioral discipline, and overall mental and physical health. Conversely, a lack of sleep in adults (regularly less than 7 hours) leads to:
- A higher probability of obesity and an increase in Body Mass Index (BMI) to 30 or more.
- An increased risk of diabetes, hypertension, and cardiovascular diseases.
- Deterioration of psychological state and an increased likelihood of depression.
- A higher risk of traffic accidents due to drowsy driving.
