Tips for boosting your winter vitamin D levels and overall health

Vitamin D is often called the ‘sunshine vitamin’ because it’s produced by our bodies when skin is exposed to sunlight. Thanks to limited winter daylight hours in the northeast, maintaining adequate vitamin D levels can be challenging and have very real consequences on our health.

Here are just a few of the ways vitamin D levels can impact your physical and mental health:

Bone Health: Vitamin D is essential for calcium absorption and bone mineralization. Without it, our bodies can absorb only 10 to 15% of the calcium we consume, which can cause our bones to become thin, brittle, or misshapen, leading to conditions like osteoporosis in adults and rickets in children.

Immune Function: Vitamin D helps modulate immune function, potentially reducing the risk of infections.

Chronic Disease Prevention: Adequate vitamin D levels may help reduce the risk of various chronic diseases, including type 2 diabetes and certain cancers.

Mental Health: Vitamin D is involved in brain development and deficiencies and can contribute to mental health issues, including depression, anxiety, irritability, and feelings of sadness.

Sleep Quality: Adequate vitamin D levels are associated with better sleep quality and regulation of the sleep-wake cycle. Fatigue and daytime sleepiness can be symptoms of Vitamin D deficiency.

The easiest way to combat low vitamin D levels is by taking a supplement. Current guidelines recommend taking 400-800 international units (IU) or 10–20 micrograms (mcg). However, your doctor may recommend taking more or less based on your age, skin color, current blood vitamin D levels, sun exposure, and more.

You can also boost your vitamin D intake by eating foods with high vitamin-D levels. These include:

  • Wild-raised salmon and oily fish

  • Egg yolks

  • Fortified milk and breakfast cereals

  • Cod liver oil

  • UV-exposed mushrooms

  • Vitamin-D-fortified cow, soy, and oat milk

  • Vitamin-D-fortified ready-to-eat cereals

When possible, spend time outdoors during daylight hours. Wearing sunscreen (as you should) will not impact your body's ability to produce vitamin D. 

In severe cases of deficiency, light therapy may be recommended.

By being proactive about vitamin D intake, you can help optimal levels of this crucial nutrient and support your overall health now and throughout the year.

Home Office How To

Did you know that many sources of chronic pain start in a poorly arranged office? Carpal tunnel, pinched nerves, overuse injuries can often be traced to chairs being positioned improperly or important tools being positioned outside easy reach. While reaching or straining once or twice wouldn't hurt us at all, doing so repeatedly day after day can cause painful and lasting injuries.

As an occupational health physician at Southwestern Vermont Medical Center, one of my responsibilities is to help employees of SVMC and other companies who have workplace injuries and recommend the adjustments they should make.

During a spike in work-from-home arrangements, I have heard about friends’ and family members' work-from-home set-ups. Some are working from laptops on their couches. Others are set up at kitchen tables. We know that their cats walk across their keyboards and their kids interrupt. Especially since Governor Scott has just indicated that remote workers will likely be the last to return to the traditional workplace, it's time to get our home office arrangements figured out.

That's why I would like to share the important details you need to arrange a healthful workspace and encourage all to invest the time (and sometimes a little bit of money) needed to implement them. Learning these points is key to avoiding injuries, as continued work-from-home policies, where feasible, will help maintain appropriate distancing needed to decrease the spread of COVID-19.

An adjustable chair is the first and most important component of an office set-up. Office chairs include crucial lumbar support and encourage good posture. When your forearms are resting on your desk or table, adjust the chair height up or down until your arms form a right angle. This is an important step in avoiding wrist pain and carpal tunnel, two of the most common office injuries. If, when your arms are in the correct position, your feet are not touching the floor, employ a footstool.

Position your monitor an arm’s length away. (If you can't see the screen from this distance, better go get an eye exam!) And raise the screen so that the top of the screen is eye level. This, too, will encourage good posture.

If you use two monitors, positioning them properly depends on how you use them. If you use them equally, the dividing line between them should be right in front of you. If you use one primarily and the other secondarily, position the more dominant screen directly in front of you. If you use a laptop, consider investing in a riser and an additional keyboard needed to raise the screen to eye level.

Put all of your other tools, including your mouse and phone, within easy reach. If you use the phone a lot, consider investing in a headset.

The only other recommendation I make is to stretch every 15 – 20 minutes. A list of helpful office-oriented stretches is available here. And every hour, be sure to get up and take a short walk or standing stretch.

If you follow these recommendations at home, you will be much more comfortable and are likely to be more productive, too, all while maintaining the social distance we need to keep COVID-19 infections low throughout this next phase of the pandemic. Most importantly, you will save yourself the pain and discomfort of office injury no matter where you're working.
