To increase height, especially after puberty, actual height growth is limited because the growth plates in bones close after puberty. However, several strategies can help maximize height potential during growth years and improve the appearance of height for adults:

• Practice good posture: Standing and sitting with proper posture can make a person appear taller by keeping the spine aligned and preventing slouching. This includes keeping shoulders back, head level, and avoiding locking knees.

• Strengthen core muscles: Strong abdominal and back muscles support the spine and reduce compression that can make a person look shorter.

• Eat a nutritious diet: A balanced diet rich in calcium, vitamin D, and other nutrients supports bone health and growth during youth, and can help prevent height loss with aging.

• Take dietary supplements: Calcium and vitamin D supplements can improve bone density, important for preventing height loss, but no supplement can increase height after growth plates close.

• Engage in regular exercise and sports like basketball, swimming, cycling, and skipping can promote growth hormone levels and healthy bone and muscle development.

• Practice yoga: Certain yoga poses can improve posture, spinal alignment, and flexibility, contributing to the appearance of increased height.

• Wear higher shoes or insoles temporarily to add height.

• Avoid habits that impact height negatively, such as smoking or poor sleep.

In summary, height increase after adolescence is very limited by biology. The best approach is to optimize growth during childhood/adolescence with nutrition and exercise, maintain healthy posture and strong muscles, and prevent height loss with aging. Yoga and posture exercises can also help one look taller through better alignment.

For teenagers and young adults still growing, proper diet, sleep, exercise, and posture maximize natural growth potential.

No proven method exists to significantly increase height once growth plates close after puberty.
