There's little worse than coming back to work after the Christmas break and finding that your colleagues have been struck down with bugs and viruses. In the cramped office space, it's very easy for bugs to run rampant, particularly if there is air-conditioning, shared desks and few open windows. So, how can you fight back? Well, surprisingly enough, hydration is key to boosting your immune system and keeping you healthy. The fact is that water plays a vital role in every single one of the body's functions – everything from keeping your skin clean and healthy to supporting the digestive function, from carrying blood through the body to supporting brain function. Water supports also muscle function, bone growth and, well, every single biological process. It’s no wonder the human body is made up of around 70% water. Because water plays a crucial role in helping the immune system stay strong, you'll need to keep well hydrated in the cold months. Go to your workplace’s water coolers for a glass of refreshing H 20 every couple of hours. Alternatively, use the office hot water dispensers to enjoy a nice cup of green tea, which is said to provide many health benefits. You'll find that as you drink more water, your taste buds will reset and you'll really start to taste your food again, meaning that you won't need to keep adding sugar to your tea! Don’t be surprised if this activity sees you lose a few inches and pounds, too. Another great tip to avoid the office winter bugs is to get outside at lunchtime for a walk, as this will keep your body healthy and your immune system strong.
