At 15 years old, you are still within the age range where growth can occur, although the rate of growth may vary significantly among individuals. The factors that influence height growth are multifaceted, including genetics, nutrition, physical activity, sleep, and overall health.
1. Genetics: Your height is largely determined by your genetic makeup, inherited from your parents. The average height of your parents can provide a rough estimate of your potential adult height, but it is not an absolute predictor. For example, if your father is 170 cm and your mother is 157 cm, your height may fall somewhere in between, but there are many variables at play.

2. Nutrition: Proper nutrition is crucial for growth. A balanced diet rich in vitamins, minerals, and proteins supports bone health and overall development. Calcium and vitamin D are particularly important for bone growth, while protein is essential for muscle development. If your diet lacks these nutrients, it could hinder your growth potential.

3. Physical Activity: Regular exercise, particularly activities that promote stretching and strengthening, can positively influence growth. Sports like basketball, swimming, and gymnastics can be beneficial. However, it is important to balance physical activity with adequate rest and recovery.

4. Sleep: Sleep is vital for growth, especially during adolescence. Growth hormone, which plays a key role in height increase, is primarily secreted during deep sleep. Therefore, poor sleep quality or insufficient sleep can negatively impact your growth potential. Aim for 8-10 hours of quality sleep each night.

5. Screen Time: While there is no direct evidence that watching TV or playing video games stunts growth, excessive screen time can lead to a sedentary lifestyle, which may contribute to poor physical health and inadequate sleep. It is essential to balance screen time with physical activity and ensure that it does not interfere with your sleep schedule.

6. Bone Age and Growth Plates: The closure of growth plates is a significant factor in determining whether you can still grow taller. Growth plates are areas of developing cartilage tissue near the ends of long bones. Once these plates close, typically in late adolescence, further height increase is unlikely. If you have concerns about your growth plates, consulting with a healthcare professional for an X-ray can provide insights into your growth potential.

In summary, at 15 years old, you still have the potential to grow taller, especially if your growth plates have not yet closed. Focus on maintaining a balanced diet, engaging in regular physical activity, ensuring adequate sleep, and managing screen time to support your growth. If you have specific concerns about your growth or health, it is advisable to consult with a healthcare provider who can offer personalized guidance based on your individual circumstances.
