We have been on this planet for a really long time; yet somehow, we continue to find ways to rethink the basics of our existence like eating, sleeping and movement. At any given moment, we can find a new trend addressing what, when and even how we should eat, sleep or exercise.

However, there are some among us who seem to function quite successfully outside of the trends, remaining healthy and happy despite challenging work environments. To prepare for winter, here are a few tips from medical professionals and frequent flyers on how to stay healthy despite working in environments full of germs.

You lose when you don’t snooze

Night nurses and frequent travelers agree that syncing up with the rhythm of their schedule is a priority. To minimize jet lag or avoid fatigue, both groups ensure that they get sound, uninterrupted hours of sleep. They also stay open to the opportunity for power naps whether it is right after takeoff or at midday; the chance for a quick reset can provide a boost for the rest of the day.

To create the best chance for a successful sleep time, both groups espouse routines and generally healthy habits. While sleep aids may not be for everyone, other common practices include skipping alcohol, adding meditation or enjoying a short session of relaxed or deep breathing.

In addition, while some people choose to forego screens and others love reading a page or two from their Kindle, most people agree that taking a break from anything that provides negative stimulation, like watching the news or reading a horror story helps ensure they can wind down physically and mentally. Ear plugs, white noise, eye masks and good neck support are all low-tech ways to create a physical environment conducive to sleep when and wherever.

Stay fresh

Next up is the idea of staying fresh both via fresh air and clean spaces. For example, when it comes to winding down and getting in a bit of exercise, frequent travelers and medical professionals agree that getting outside for deep breaths, a walk or a run can help us stay healthy, get in sync with our local environment and relax.

In addition, ensuring we are operating in a clean space is important. Wiping down surfaces in which multiple people come in contact and washing hands well and frequently are two basic but critical ways to limit exposure to illness (think keyboards, armrests, phones and counters).

Similarly, watching what we do with our hands, from keeping them away from our face to covering our coughs and sneezes with our inner elbow, we can further restrict the spread of unhealthy particles.

Finally, ensuring we are hydrated by drinking plenty of non-sugary, non-caffeinated liquids can keep our internal systems running smoothly. And should we start feeling the effects of illness or fatigue, ensuring we stay hydrated can help our immune system.

The bottom line is staying healthy does not have to be rocket science; if we stick to the basics, we will all have a better chance of limiting our illnesses.
