What time should one sleep to increase height?

Sleep plays a crucial role in promoting growth and development in children and adolescents. In addition to a well-balanced diet and regular exercise, taking care of sleep is also important for children to achieve their ideal height early. So, what time should children go to bed and how should they sleep to optimize and accelerate height growth?

How does sleep affect height?

The vertebrae are separated by intervertebral discs, which perform an important function of allowing you to move, bend, stretch, and rotate your spine. These discs then become a type of cushion between pairs of vertebrae and are made of cartilage tissue that provides high elasticity. When we sleep at night, the spine is not affected by the pressure of body weight, and therefore, the intervertebral discs can expand and stretch, which is synonymous with bone development.


Therefore, sleep deprivation can affect the process of bone formation in the human body. People with sleep disorders have lower bone density and reduced bone flexibility. In addition, the body also performs metabolic exchange, eliminates excess substances, and converts energy while you sleep. These activities help the process of height development to occur more smoothly.

How many hours of sleep should you get to increase height effectively?

During deep sleep, the body produces the necessary hormones for growth. That is why health experts recommend that children and adolescents in the height development period should go to bed before 10 p.m. Thus, you can achieve deep sleep around 11 p.m. – 1 a.m. in accordance with the body’s normal daily cycle. The ideal time to go to bed is 9 p.m.

Some tips to improve sleep for increasing height:

Avoid exposure to blue light from mobile phones and computers before going to bed to prevent sleep disturbances.

  • Do not eat too much at night or right before bed.
  • Sleep with a relaxed mind, limit stressful, and tired feelings that lead to difficulty falling asleep.
  • Sleep in a dark, quiet room, avoiding overly bright light while sleeping because light makes the brain more alert.
  • Check the air in the bedroom, ensure clean air and ventilation.
  • Choose comfortable sleepwear, avoid tight-fitting clothes that can affect bone development.
  • Keep your hands and feet warm for easier deep sleep.
  • You can drink a warm glass of water 30 minutes before bedtime to keep your body warm. It acts as a sedative to help you sleep better.
  • Avoid using nerve stimulants such as alcohol, beer, caffeine… at night or before bedtime.
  • Sleep in a comfortable position by lying on your back or on your side, using a pillow that is at the right height.
  • Sleep on a comfortable and firm surface, a mattress that is not too hard or too elastic to keep your spine straight and healthy.

You can also do some gentle exercise, listen to soft music, or read a few gentle pages of a book before going to bed for 20-30 minutes.

This exercise is often combined with a chair or a stool that matches the height of the person, helping to relax the back muscles. You kneel on a mat, place a chair in front of you, then loop or place your hands on the chair and straighten your arms to grip the chair. You can also use a thin cushion under your knees, bend forward completely, and breathe evenly. Hold this position for about 5 – 10 minutes, then relax by lying on your back on the floor.
