How Vitamin D and Exercise Work Hand in Hand

We all know vitamin D as the sunshine vitamin, as you can get it from the sun! This is an important nutrient that helps absorb calcium and phosphorous, minerals that are vital in building bones. It’s also said that vitamin D can help reduce cancer cell growth and inflammation! This is why many people take vitamin D supplements from brands like Pure Encapsulations from Supplement First.

But wait, there’s more to learn about vitamin D, particularly when it comes to working alongside regular exercise. Both exercise and vitamin D are separately known to reduce the risk for heart disease, but what about when having adequate amounts of exercise and vitamin D together?

Read on to find out! 

How Exercise Impacts Vitamin D

The assumption is that exercise helps increase vitamin D because of the sun exposure received. About 90% of the vitamin D our bodies need comes from the sun.

That said, there is mixed research in terms of whether we should partake in indoor or outdoor activities since both seem to show positive effects on vitamin D.

People who meet adequate physical activity recommendations and optimal vitamin D levels experienced a reduced risk of cardiovascular events compared to those with low vitamin D levels. 

What Vitamin D Does for Exercise

There is one study that shows higher levels of vitamin D are associated with increased exercise capacity.

This is likely because how vitamin D plays a crucial role in heart health. When increasing your vitamin D levels to the recommended amount daily, you may be able to increase your exercise capacity as well, thus improving your heart health.

A study from Harvard also showed that people who exercise regularly and vigorously exhibited higher vitamin D levels! 

Supplementing with Vitamin D

Now that you know how exercise and vitamin D go hand in hand, the next question is if you must take supplements from brands like Integrative Therapeutics.

It isn’t completely clear if vitamin D is a driver to improve fitness and vice versa. The speculation is that both work together and mutually benefit from one another. That said, it doesn’t mean you should start supplementing right away.

This is because you might already be getting enough vitamin D already from adequate sun exposure and a healthy diet. That’s why it’s crucial to first check with your doctor if you require vitamin D supplements. Your healthcare provider will be able to conduct tests and determine if you are deficient in certain nutrients and require supplements.

But do note that even if your doctor decides to add vitamin D supplementation to your routine, it might not improve your athletic performance alone. It may provide greater benefits, but you’ll want to first get your nutrients from natural and food sources. This means getting enough sunlight exposure and adding more foods like fish, eggs, and fortified foods to get enough vitamin D.

Before you start taking vitamin D supplements, check with your doctor. 

Wrapping It Up

Make sure you get adequate exercise and nutrients like vitamin D through a healthy diet!

Getting Value for Money: What to look for when shopping for a lab refrigerator or freezer

Quality control is essential for their establishment of a properly functional lab.  One of the hallmarks of a well-run lab is consistency in its QC procedures. And, a high-quality lab refrigerator is a key component of those procedures. Whether it’s chemicals, compounds, samples, or specimens; unless properly refrigerated or frozen to specification, it can significantly impact the quality and reliability of the procedure, test, or experiment.

More Than Temperature Control

While it’s cooling or freezing capabilities are crucial, because your lab freezer is such a central element of your operations, it’s important to raise the bar for selecting your cooling or freezing equipment. Yes, design and size matters too, but so do several other features.

Here’s a list of things you should look for when looking for the perfect refrigerator or freezer:

  • Temperature Range

This is a no-brainer! It all depends on the equipment you’re looking for, which may range from an ULT freezer to cryogenic units, or a general purpose lab refrigerator. Each have their unique temperature capabilities. For instance, ultra-low temperature freezers may vary from -30 o F to -40o F, while many cryogenic freezers offer ranges of -238o F and above. For general duty refrigerators, that range may vary between 32o F to 50o F. Make sure you buy the one that fits the needs of your lab.

  • Safety and Monitoring

Look for additional features, including warning alarms, monitoring panels, LED information displays, and temp alarms. It’s advantageous to have the ability to modify settings according to your labs’ needs.  Another key feature is the “Alarm systems”.  These systems monitor temperature and send an email, SMS text, or voice alarm to the lab staff to warn of temperature deviations beyond the operator’s max or min parameters.

  • Datalogging

Most mid and high range laboratory refrigerators and freezers have either temperature recorders (paper) or digital recorders.  Some include wireless monitoring features that laboratory staff can use to verify sample security and validate cold chain compliance, either through their local area networks (LAN) or via cloud storage systems. Smart data logging features also empower lab monitoring staff with the ability to check refrigerator data readings from anywhere – at home, at satellite office locations, or on the go – using their mobile devices.

  • Size, Ergonomics and Placement

Don’t order your lab refrigerator first, and then try to fit it in your lab! Ask the tough questions first: How big a freezer or refrigerator do I need? Can I make do with two smaller units, instead of a single larger one? Where is the best place to locate it so staff can access it easily? Which other equipment makes most sense to house near your freezer or refrigerator? Can doors slide or swing open without obstruction? Check your floorplan and layout before making these decisions.

  • Ease-of-Use

Today’s laboratory freezers and refrigerators are built with user-friendly designs, therefore enabling ease of user interaction. Intuitive controls, including digital panels, touch-sensitive controls, and helpful icons and imagery, remove operator guesswork when using the equipment.  Features such as vacuum relief ports, and the use of magnetic door gaskets, make the equipment ergonomically friendly to use and operate.

Sourcing Your Freezers and Refrigerators

Once you’ve performed your assessment, it’s time go shopping. It is not always the best choice to order a new lab freezer or refrigerator. Don’t hesitate to shop for refurbished or previously used options. You’ll be amazed at how many laboratories recycle their previously used units after a short service life. They surplus their old equipment which gives start-up labs the opportunity to acquire them at cost-effective prices.
