In general, foods that take longer to digest can help raise your body temperature and make you feel warmer. The medical term for this process is thermogenesis, which is the process of your body producing heat caused by food metabolizing. Look for food that’s high in healthy fats, proteins and carbohydrates. Many of these foods take longer to digest.

Drink Ginger Tea
Hot ginger tea can make you feel warm inside on a cold day. Ginger is known to be good for digestive health and can stimulate thermogenesis. It’s also a diaphoretic, which means it will help your body warm from the inside out. Keeping you warm is only one of the many health benefits of drinking ginger tea.
One of the benefits to drinking coffee is the caffeine. Caffeine increases your metabolism, which can raise your body temperature. Technically, iced coffee can be even better because it has more caffeine. However, if you can’t give up the warm cup of coffee in your hands, you’ll still get the benefits from a hot cup of coffee.

Eat Red Meat
Red meat, such as beef, lamb and pork, is a good source of iron. Iron is an important mineral to help carry oxygen throughout your body. People with low iron may notice cold hands and feet or feel tired easily. Eating red meat can also supply vitamin B12, which contributes to healthy nerves and a strong immune system.
Eat Sweet Potatoes
Sweet potatoes and other root vegetables need more energy to move through the digestion process, which raises your body temperature.

A simple way to help your body stay warm this winter is to drink water. Water keeps your body functioning at its best and helps regulate your internal temperature. Dehydration causes your core temperature to drop, which may lead to hypothermia. People are less likely to drink water when it’s cold outside because they don’t feel as thirsty, according to Summit Medical Group. You may want to carry a water bottle with you to serve as a reminder.
You may follow the old adage that a shot of whisky can keep you warm. However, whisky and other kinds of alcohol actually lower your body’s core temperature.
