Winter has certainly came earlier than usual this year in Sydney. At least it feels that way this year around.
When winter comes, many of us tend to neglect many usual routines that keep our skin and complexion healthy. We tend to drink less fluid, keep a less than healthy diet, do less exercise and keep our hands and feet hidden away in cloves and socks with closed shoes. But this is not what your doctor, your nutritionist nor your dermatologist/beautician would prescribe.
Quite the contrary actually.
The air is much dryer in Winter and there are many more air-borne bacteria and viruses abound (one of many reasons why we all catch a cold or flu this season), thus we need to keep up with usual regiment of healthy eating, lots of exercise, drink a lot of fluids (distilled or purified water is good 
) and use plenty of moisturiser cream to keep your skin moist and healthy. Especially for your hands and fingernails, keep using hand lotion and/or cuticle oils at least in the morning and at night time. Remember that because winter is cold, we tend to wash our hands in hot water more often than not. Plus other cleansing agent/chemical which can really make our hands and nails too dry and even brittle.
Keep yourself healthy and beautiful all seasons, not just for the warmer ones!
