Does lack of sleep affect height?

Sleep is a crucial aspect of every human being’s life. It plays a vital role in maintaining physical and mental health. The majority of our growth occurs during the time we spend sleeping, especially in children and adolescents. Parenting books warn parents to put their little ones to bed earlier so they can grow taller. Is there any truth behind this myth? In short, lack of sleep does impact height growth, but how much? Let’s dig deep into what science has to say.

How Growth Hormones are Released

Before getting into the connection between sleep and height, it is essential to understand how growth hormones work.

Growth hormone (GH) gets produced in the pituitary gland located at the base of your brain. These hormones promote bone density, muscle mass, mood balance, cognitive sharpness and many other functions in both adults as well as children.

The release of these hormones follows two patterns: spikes after intense exercise or metabolic stressors like fasting; approximately an hour after falling asleep for most people^[1].

Can Sleep Deprivation Stunt Your Growth?

Inadequate amounts of GH due to poor sleep quality may cause developmental issues for growing kids^[2]. Research shows that deep thir-stage NREM (non- REM) or slow-wave sleep stimulates pulse releases from the pituitary gland – this process also declines with age^[3].

Children who experience interrupted or irregular nighttime sleep exhibit low levels GH secretions which ultimately lead to shorter stature reflected throughout adulthood^[4].

The Ideal Sleeping Hours for Children

During infancy you’d be lucky if babies let parents get more than 3 hours consecutive shuteye before waking up grumpy! Youngest infants typically require about 14–17 hours per day while teenagers aged 14-17 | average 8-10 hrs/night recommended. Any less than that tends to cause sleep debt overtime and may affect growth hormones release with age^().

What About Adults?

Though adolescence is a critical period to get adequate rest for GH, some studies suggest that poor sleep can harm adults as well^[5]. Interrupted or inadequate sleeping schedules may lead to early onset of chronic bone-deteriorating diseases such as osteoporosis. In short: it never hurts to get more rest!

Other Factors that Affect Height

While lack of sleep is important, height is determined by many other factors. These include genetics, nutrition, physical activity level during childhood / young adulthood (critical periods), environmental conditions like weather patterns affecting availability fresh foods / daily outdoor activities (e.g., sunlight).


Height has significant genetic ties in modern populations^[4]. Some families are born taller; others significantly shorter irrespective sleeping behaviours from outside influences.

If your ancestors are on the tall side chances you inherited those genes passed down via nature and nurture ‘your family’s lifestyle habits. However upbringing can play a role there too – it’s tough acquiring an optimal posture if growing up within low income housing w/ limited space opportunities exercise.

Nutritional Factors

Nutrition also plays a crucial role in determining one’s height potential. Feeding children calcium-rich food items could prove useful for growing bones during infancy and avoid deterioration later in life.

Physical Activity

Active physical lifestyle – sports, running around, playing hide-and-seek during early development stage – can help in developing an optimal height. Exercise is essential for growing children as it promotes muscle and bone formation while encouraging better sleep patterns [7].

Environment Factors

Maintaining a healthy environment between temperature, fresh air circulation / proper ventilation plays a critical role improving growth curve.

In conclusion: sleeping routine does affect individual growth hormones release/saturation potentially limiting height from infancy standard to late teens/early adulthood.

Incorporating all these crucial components into your child’s life along with adequate wholesome rest will lead to overall suitable wellbeing of both mental & physical states ^(9)^!.
