Growing Season

We all know about the growing season of plants, but were you aware that children grow faster in the spring due too? That growth spurt is due to several factors, among them, increased Vitamin D. Vitamin D is essential for bone growth. Longer days and increased sunlight in spring boost vitamin D levels, which play that very key role in supporting a child’s bone growth. Another factor is that of hormonal regulation…increased daylight hours can lower melatonin levels, which may enhance growth hormone secretion, promoting faster growth. In addition, more time spent outdoors during spring allows children to engage in physical activities that stimulate growth. In the spring, fresh produce is easier to find, making it simpler to enjoy a balanced diet that encourages growth. Altogether, these factors make spring an ideal time for childhood growth.

It might seem surprising, but research shows that kids often grow faster in the spring, thanks largely to more sunlight and better nutrition. Several studies have found that the biggest growth spurts happen during these months. For example, a 2015 study of 760 Danish students revealed peak growth in April and May, while a 2022 study of thousands of Texas children also reported strong growth rates in spring and early summer.

The second-best growing season is summer. One of the most significant factors driving summer growth spurts is the relationship between sleep patterns and growth hormone release. Of course, when the kids don’t have to get up early to get ready for school, many of them tend to sleep half of the morning away. Growth hormone secretion occurs predominantly during deep sleep, particularly during the first third of the night when deep, non-REM sleep is most abundant. During summer months, children typically enjoy more relaxed schedules, allowing for longer and higher-quality sleep. This extended rest period provides more opportunities for growth hormone release. The combination of less school stress, warmer weather, and longer days often leads to better sleep quality for children. Without early morning school schedules, kids can follow their natural sleep patterns more closely. CMC Pediatrics emphasizes the importance of maintaining good sleep hygiene year-round, but particularly during these crucial growth periods. Children experience a rush of growth hormones both when they fall asleep and when they wake up. Longer summer sleep periods allow these hormones to work more effectively, contributing to the dramatic height increases many parents observe in their children.

Of course, another big part of growth is good nutrition, and when your child suddenly seems hungry all the time, their body is likely preparing for or experiencing a growth spurt. Their increased caloric demands are very likely part of the need for extra energy as part of that growth spurt too. Growth happens all year round, but kids often experience a boost in spring. Longer days, better nutrition, more time spent being active, and improved sleep all play a role in this seasonal spurt. Parents can help by encouraging outdoor fun, offering balanced meals, and making sure their children get plenty of rest during these lively months. Oh, and plan on needing new clothes before school starts again, because that is just a part of the deal.
