Avoid crowds and keep your distance from people whom you know are ill
Avoid sharing objects
Avoid touching your nose, mouth and eyes
Wash your hands frequently, especially when returning home from a public place, after blowing your nose, coughing, sneezing, being with ill people and especially before you eat
Get plenty of sleep. Not getting enough sleep will negatively affect your immune system, leaving you more vulnerable to cold and flu viruses. Be aware of what your body needs (8 hours may not be enough for you), and supplement it with quick cat-naps of 15 to 30 minutes if you can.
Stay hydrated. Living and working inside with the heat on can really dry you out, and it’s more difficult to remember to drink water when it isn’t hot outside.
Get sunshine on your body. Exposing yourself to the sun every day boosts vitamin D production and helps to lift your mood, which affects your immune response.
Be positive. Having a positive outlook may be one of the most important things you do for your health.
Eat more fruits and veggies. Vegetables and fruits are nutritional powerhouses, and with citrus coming into season in the winter, eating lots of oranges is a cheap way to support your immune system.
