Winter Bone Health: Why Vitamin D Matters More Than Ever

LEBANON, OH -- As temperatures remain low and daylight hours are limited, health experts are warning about an often-overlooked seasonal risk: weakened bones. Vitamin D deficiency is especially common in the winter months due to reduced sun exposure, and the consequences can be serious for long-term bone health.

“Vitamin D plays a critical role in helping the body absorb calcium and maintain strong, healthy bones,” said Joseph Kershner, DO. “When levels fall too low, which is common in the winter, patients are at greater risk for osteoporosis, fractures, and slower healing if an injury occurs.”

According to the National Institutes of Health, millions of Americans have insufficient vitamin D levels, with deficiencies more likely to appear in January and February. Older adults, individuals with limited outdoor activity, and those with darker skin tones are particularly vulnerable.

Mercy Health experts recommend the following steps to stay protected this winter:

• Check your vitamin D levels. A simple blood test can identify deficiencies.
• Incorporate vitamin D-rich foods. Fatty fish, fortified dairy products, and egg yolks can help.
• Consider safe supplementation. Talk to your doctor before starting vitamin D supplements.
• Stay active. Weight-bearing exercise, like walking or light strength training, strengthens bones.

“Fractures from slips and falls are also more common in the winter, so it’s important to do everything possible to protect bone health before an accident happens,” added Dr. Kershner. “Maintaining strong bones today means fewer risks tomorrow.”

Make your health a priority this season. Contact your healthcare provider today to learn more about your individual risk factors and which health screenings are right for you. They can also ensure you’re up to date on any vaccinations to help prepare you for other health risks and illnesses that become prevalent during the winter months.
