Why You Should Go For Vitamin D But Not Vitamin C To Prevent The Common Cold

Why You Should Go For Vitamin D But Not Vitamin C To Prevent The Common Cold

When it comes to vitamins, it can all be a bit confusing as to which ones help prevent which ailment. However, there are some vitamins we can all rely on to know their purpose and preventable abilities, such as vitamin C which is well known for being the best for supporting us through colds and flu. But is this entirely true? Is there a more effective vitamin that can help with preventing us from catching colds and flu?

If latest research is anything to go by, the answer is yes and it may be surprising to hear that it’s actually vitamin D. Our ideas of vitamin D are usually synonymous with bone health which is entirely true, but it has emerged that vitamin D has been vastly underestimated in its important role of improving our immune systems.

Vitamin C vs. Vitamin D

While getting enough vitamin C is helpful towards preventing colds, we are led to believe that we need more of it to get better and improve immunity. The real truth is, we get plenty of vitamin C in our diets. Easily obtainable and common foods such as fruits (strawberries, melon, tomatoes and citrus fruits) and vegetables (green leafy vegetables, cauliflower, broccoli and brussels sprouts) all contain high levels of vitamin C so a balanced healthy diet will supply more than enough.

On top of that, vitamin C isn’t as effective at improving our immune systems as we are led to believe. While it can help towards fighting a cold, it actually makes little impact.

Latest studies have shown a link between low vitamin D levels and higher cases of common respiratory infections. While it’s essential for bone health, vitamin D is multi-purposeful and is thought to be much better than vitamin C in its immunity role. A study was conducted involving 19,000 participants using data from a national health survey between 1988 and 1994. It showed 36% of those with low levels of vitamin D in their blood were more likely to report having a recent upper respiratory tract infection than those with higher levels.

Although these studies are just coming through and more research needs to be done, there are more and more strong links between chances of catching colds and low levels of vitamin D.

Getting Enough Vitamin D for Our Body

The problem is that vitamin D is much harder to produce in the body. With reduced exposure to sunlight in many countries especially in the winter, a large percentage of people have a vitamin D deficiency, therefore not getting the full benefits of what vitamin D can do for their immune systems.

This is why diet and supplements are key to getting the sufficient amount of vitamin D we need in order to help prevent colds and flu more efficiently.

Foods such as egg yolks, canned tuna, liver, cod liver oil, fortified milk, and fortified cereals can give you a boost of vitamin D along with supplements ‒ and a dose of sunlight as vitamin D forms in our skin in response to the sun’s rays (just 10 minutes is enough). While upping your vitamin D intake may help towards preventing yourself from getting sick, a consistent daily intake is needed for it to have a successful effect.

Vitamin D and The Common Cold

While more and more research is pointing to increasing your vitamin D levels to fight cold and flu, it’s important to realize that it only helps to boost the immune system and isn’t a preventative measure in itself. Living a healthy lifestyle with a varied, healthy diet and regular exercise is needed to strengthen our immunity and to ward off the nasty bugs and viruses that get into our body.

The research is promising but it has its limits as to what the ideal level of vitamin D is for supporting immune system responses to infection. All they know is that making the conscious effort to increase depleting vitamin D levels is a must for overall health. So if you want to know how to prevent a cold this winter, reach for the vitamin D instead of the vitamin C and see if it makes a difference.

20 Time Management Tips to Super Boost Your Productivity

20 Time Management Tips to Super Boost Your Productivity

Are you usually punctual or late? Do you finish things within the time you stipulate? Do you hand in your reports/work on time? Are you able to accomplish what you want to do before deadlines? Are you a good time manager?

If your answer is “no” to any of the questions above, that means you’re not managing your time as well as you want. Here are 20 time management tips to help you manage time better:

1. Create a Daily Plan

Plan your day before it unfolds. Do it in the morning or even better, the night before you sleep. The plan gives you a good overview of how the day will pan out. That way, you don’t get caught off guard. Your job for the day is to stick to the plan as best as possible.

2. Peg a Time Limit to Each Task

Be clear that you need to finish X task by 10am, Y task by 3pm, and Z item by 5:30pm. This prevents your work from dragging on and eating into time reserved for other activities.

3. Use a Calendar

Having a calendar is the most fundamental step to managing your daily activities. If you use outlook or lotus notes, calendar come as part of your mailing software.

I use it. It’s even better if you can sync your calendar to your mobile phone and other hardwares you use – that way, you can access your schedule no matter where you are. Here’re the 10 Best Calendar Apps to Stay on Track .

4. Use an Organizer

These Top 15 Time Management Apps and Tools can help you organize better, pick one that fits your needs.

5. Know Your Deadlines

When do you need to finish your tasks? Mark the deadlines out clearly in your calendar and organizer so you know when you need to finish them.

But make sure you don’t make these 10 Common Mistakes When Setting Deadlines.

6. Learn to Say “No”

Don’t take on more than you can handle. For the distractions that come in when you’re doing other things, give a firm no. Or defer it to a later period.

Leo Babauta, the founder of Zen Habits has some great insights on how to say no: The Gentle Art of Saying No

7. Target to Be Early

When you target to be on time, you’ll either be on time or late. Most of the times you’ll be late. However, if you target to be early, you’ll most likely be on time.

For appointments, strive to be early. For your deadlines, submit them earlier than required.

Learn from these tips about how to prepare yourself to be early, instead of just in time.

8. Time Box Your Activities

This means restricting your work to X amount of time. Why time boxing is good for you? Here’re 10 reasons why you should start time-boxing.

9. Have a Clock Visibly Placed Before You

Sometimes we are so engrossed in our work that we lose track of time. Having a huge clock in front of you will keep you aware of the time at the moment.

10. Set Reminders 15 Minutes Before

Most calendars have a reminder function. If you have an important meeting to attend, set that alarm 15 minutes before.

You can learn more about how reminders help you remember everything in this article: The Importance of Reminders (And How to Make a Reminder That Works)

11. Focus

Are you multi-tasking so much that you’re just not getting anything done? If so, focus on just one key task at one time. Multitasking is bad for you.

Close off all the applications you aren’t using. Close off the tabs in your browser that are taking away your attention. Focus solely on what you’re doing. You’ll be more efficient that way.

Lifehack’s CEO has written a definitive guide on how to focus, learn the tips: How to Focus and Maximize Your Productivity (the Definitive Guide)

12. Block out Distractions

What’s distracting you in your work? Instant messages? Phone ringing? Text messages popping in?

I hardly ever use chat nowadays. The only times when I log on is when I’m not intending to do any work. Otherwise it gets very distracting.

When I’m doing important work, I also switch off my phone. Calls during this time are recorded and I contact them afterward if it’s something important. This helps me concentrate better.

13. Track Your Time Spent

When you start to track your time, you’re more aware of how you spend your time. For example, you can set a simple countdown timer to make sure that you finish a task within a period of time, say 30 minutes or 1 hour. The time pressure can push you to stay focused and work more efficiently.

You can find more time tracking apps here and pick one that works for you.

14. Don’t Fuss About Unimportant Details

You’re never get everything done in exactly the way you want. Trying to do so is being ineffective.

Trying to be perfect does you more harm than good, learn here about how perfectionism kills your productivity and how to ditch the perfectionism mindset.

15. Prioritize

Since you can’t do everything, learn to prioritize the important and let go of the rest.

Apply the 80/20 principle which is a key principle in prioritization. You can also take up this technique to prioritize everything on your plate: How to Prioritize Right in 10 Minutes and Work 10X Faster

16. Delegate

If there are things that can be better done by others or things that are not so important, consider delegating. This takes a load off and you can focus on the important tasks.

When you delegate some of your work, you free up your time and achieve more. Learn about how to effectively delegate works in this guide: How to Delegate Work (the Definitive Guide for Successful Leaders)

17. Batch Similar Tasks Together

For related work, batch them together.

For example, my work can be categorized into these core groups:

  1. writing (articles, my upcoming book)
  2. coaching
  3. workshop development
  4. business development
  5. administrative

I batch all the related tasks together so there’s synergy. If I need to make calls, I allocate a time slot to make all my calls. It really streamlines the process.

18. Eliminate Your Time Wasters

What takes your time away your work? Facebook? Twitter? Email checking? Stop checking them so often.

One thing you can do is make it hard to check them – remove them from your browser quick links / bookmarks and stuff them in a hard to access bookmarks folder. Replace your browser bookmarks with important work-related sites.

While you’ll still checking FB/Twitter no doubt, you’ll find it’s a lower frequency than before.

19. Cut off When You Need To

The number one reason why things overrun is because you don’t cut off when you have to.

Don’t be afraid to intercept in meetings or draw a line to cut-off. Otherwise, there’s never going to be an end and you’ll just eat into the time for later.

20. Leave Buffer Time In-Between

Don’t pack everything closely together. Leave a 5-10 minute buffer time in between each tasks. This helps you wrap up the previous task and start off on the next one.
