Prevention is always better than a cure, so to keep our bodies healthy over winter, and to protect against common colds, GP and Medical Broadcaster Dr Sarah Jarvis shares her 6 top tips to help prevent and treat the common cold.
EAT COLOURFUL FRUIT & VEG
"Eating plenty of fruit and vegetables, especially those with brighter colours,
give you a good dose of vitamins: the vitamin C and antioxidants they
contain in particular are great little cold fighters. Cooking vegetables in
warm wholesome soups can give you that extra cosy feeling at the same
time as giving your body the nutrients it needs."
TAKE SUPPORTIVE PRODUCTS
"Taking vitamin supplements like Vitamin D and Zinc will also help support
the immune system. Some products like ColdZyme® can help protect
against or can shorten the duration of a cold if used at an early stage, by
acting on the virus itself. It works by forming a fast-acting protective
barrier in the mouth and throat where colds and flu develop".
ColdZyme® (20ml £17.50) (7ml one cold application £9.89) is available
from Amazon, independent pharmacies and Boots stores nationwide.
DRINK PLENTY OF WATER & limit caffeine
"Staying hydrated is always important, but when you have a cold you
can become dehydrated. Drink plenty of non-alcoholic fluids and limit
your caffeine intake to about 400mg (equivalent to about 4 cups of
brewed coffee or 8 cups of tea) a day: at levels above this, caffeine stops
rehydrating and can act as a diuretic, making you pee out more fluid. "
GET THE RIGHT AMOUNT OF SLEEP
"Getting enough sleep is vital, especially when we are ill. This is when
the body is working at its hardest to fight infection and inflammation.
Popping a hot (not too hot!) towel over your upper face can feel
soothing but also will dilate the nasal passages giving you a little
respite from the congestion and allow you to drift off."
THE POWER OF A WARM BATH
"A warm bath before bed can be very soothing when you have a cold
and can leave you feeling comfortably drowsy and better able to sleep."
EXERCISE
"It may seem odd to suggest exercise when you are feeling poorly, but it’s
surprising how much just a 20-minute walk in the fresh air can help your
breathing, boost your energy levels and ease your symptoms."
