Dress smart
Wear multiple layers of light and warm clothes as it will keep your body heat insulated. Choose clothes made of wool, cotton or fleeced synthetic fibres.
Keep your extremities covered as they are the first parts of your body to lose circulation in cold temperatures. Wear a scarf, mitten and woollen cap when you are heading out.
Eat right
Eat at regular intervals as the burning of food will keep your body warm. Include lots of food items which are rich in protein.
Take hot drinks often to maintain your body temperature.
Move your body
Physical activity helps generate heat and fight cold. Engage in your daily exercise and chores to stimulate blood circulation and also prevent joints and muscles from stiffening.
Use hot water bottle
Stay warm with a hot water bottle. You will find hot water bottles in any department store or you can make one yourself by filling a glass bottle with hot water and wrapping it with a towel.
