Exercise and your immune system
The government is always talking about fitting more exercise in to lose weight but it can also stop you from catching colds and makes you happier - probably not while you're doing it though! They recommend increasing your heart rate for 30 minutes every day, and doing any form of exercise for more than this length of time will boost your immune system too.
This is because when you exercise your body releases endorphins, or 'feel good' hormones. This increases your energy levels and the more energetic you are the more energetic your immune system will be.
And, hand in hand most of the time with exercise is being outdoors. Most people spend 90% of their time indoors breathing in filtered air or other people's germs. Being out in the cold, as long as you're wrapped up properly, kills any germs that are lingering.
