While some research links more rest in youth to increased height, it is unclear if sleeping make you taller as an adult. Genetics and nutrition are the primary drivers of stature.
How Sleep and Genetics Affect Your Ability to Grow Taller
A person’s final height is mostly determined by a complex mix of genetics, environment, and nutrition. Over 3,000 gene variants can influence how a child grows.
Sleep is connected to growth through the pituitary gland in the brain, which produces human growth hormone (hGH). Since the body releases most of this hormone at night, children who do not get enough sleep may have lower hGH levels. However, a true deficiency in this hormone is rare, and researchers do not believe a temporary lack of sleep in childhood changes a person’s adult height.
The Process of Physical Growth
Children grow as new tissue develops in the growth plates located at the ends of long bones, such as those in the fingers, forearms, and thighs. This does not happen at a steady rate but occurs in growth spurts:
- Infancy: Rapid growth occurs, with some babies growing about 10 inches in their first year.
- Childhood: Growth typically averages 2 to 4 inches per year from age 2 until early adolescence.
- Adolescence: A peak spurt often begins between ages 8 and 12, with some children growing 3 to 4 inches annually.
Growth stops when the growth plates close. This timing varies based on sex, age, and physical maturity.
Predicting and Managing Height
Doctors use several methods to estimate a child’s future height, including bone age X-rays of the wrist and hand, growth charts, and the “midparental height” method, which averages the parents’ heights with a small adjustment based on the child’s sex.
While healthy eating and adequate sleep support development, most medical interventions to grow taller are controversial. Growth hormones for healthy children are costly and require years of daily injections without guaranteeing results. Bone lengthening surgery is also controversial for cosmetic use due to safety risks.
Height Changes in Older Adults
It is common to lose height after age 40, averaging about half an inch every decade until the 70s, when the loss accelerates. This is often due to changes in muscles, joints, and bones. To slow this process, adults can:
- Maintain a varied, healthy diet.
- Exercise regularly.
- Limit tobacco and alcohol use.
- Discuss osteoporosis risks with a healthcare provider.
FAQ
Does lack of sleep affect a person’s height?
While sleep loss may impact the production of human growth hormone, there is no evidence that a temporary lack of sleep during childhood affects adult height.
Do growth hormones help children grow taller?
Doctors may prescribe them for rare growth hormone deficiencies. However, using them for otherwise healthy children is controversial because they are expensive and not always effective.
How can I tell if a child’s height is normal?
Doctors look at “growth velocity”—the rate of growth over time—rather than a single measurement, comparing it to average growth charts for that age and sex.
When to See a Doctor
Consult a healthcare provider if you notice atypical growth patterns in a child. Warning signs or factors that may require medical evaluation include:
- Growth delays caused by malnutrition or chronic infections.
- The use of stimulants or glucocorticoids.
- Genetic disorders or chronic health conditions.
- Emotional health issues affecting development.
