When the days get colder, we all reach for warm clothes and blankets and turn up the heating a notch. However, real body heat does not only come from outside, but is mainly generated internally. Everything you eat activates processes in your body, such as digestion and metabolism, which release energy. But which foods have a warming effect? We investigated this for you!
In this article, you will read:
- What warming foods are
- How food can warm your body
- Which foods can bring warmth from within
- How supplements can help
What are warming foods?
Warming foods help your body warm up from the inside and go beyond just the temperature of your meal. When it comes to nutrition, we usually focus on carbohydrates, proteins, fats (macronutrients) and vitamins, minerals and trace elements (micronutrients). However, according to Traditional Chinese Medicine (TCM) and Ayurveda, it is also important to consider the properties of food: some foods have a warming effect, while others have a cooling effect.
It is mainly ingredients such as certain herbs and spices that have this effect. They do not feel warm to the touch, but can have a warming effect. Ayurveda also focuses on the digestive fire, or agni. A strong agni ensures that your body can produce more heat and energy and absorb nutrients better. Warm dishes, warming herbs and specific flavours help to keep your body and energy levels in balance, especially during cold or stressful periods.
How internal heat is generated in your body
As soon as you eat, your body starts working to digest nutrients and convert them into usable energy. Not only calories, but also the composition of your diet influences how warm your body is. Proteins and healthy fats are particularly valuable in this respect: they provide long-lasting fuel and stimulate the digestive process, which supports the internal production of heat (thermogenesis). This has a slightly warming effect, as if a mini heater were turned on in your stomach.
When energy is released slowly and efficiently, your body can produce heat for longer without your blood sugar crashing or your energy “leaking away”. At the same time, your blood circulation also plays a role: certain ingredients help your blood vessels to relax slightly or stimulate circulation, allowing heat to be distributed more effectively throughout your body. This means that after some meals you can literally experience a warmer sensation than after others.
Foods that have a warming effect
1. Ginger
In Ayurvedic medicine, ginger is considered one of the most powerful warming herbs. It stimulates digestion, promotes blood circulation and helps remove excess mucus, keeping the body in internal balance. Modern science also confirms the warming effect of ginger: in one study, a significant increase in hand temperature was observed after drinking ginger tea, indicating improved blood flow and an immediate feeling of warmth. By regularly adding ginger to your meals or tea, you give your body a natural, internal warmth boost.
2. Winter vegetables
Nature gives you exactly what you need! Winter vegetables such as kale, parsnips, Brussels sprouts, pumpkin, onions, carrots, red cabbage and sweet potatoes are ideal for warming your body from the inside during the cold months. They are packed with vitamins, minerals and fibre that support your metabolism, maintain your energy levels and stimulate digestion. By preparing these vegetables in soups, stews or casseroles, you help your body produce extra heat, while also benefiting from their nutritional value and the comfort these winter meals provide.
3. Nuts and seeds
Certain nuts and seeds, such as pistachios, pine nuts, sesame seeds and walnuts, have a warming effect according to Ayurvedic health teachings. In addition, the healthy fats in nuts act as an internal heater for your body. They provide long-lasting energy, giving your body a constant supply of fuel to produce heat.
4. Cinnamon
The smell of cinnamon often reminds us of winter. Fresh apple pie, cinnamon rolls or a chai latte: cinnamon is not only delicious, it also has a warming effect on your body. It stimulates blood circulation and supports your metabolism, allowing energy to flow through your body more quickly and giving you a subtle feeling of warmth. Cloves and nutmeg are also spices that can have this effect.
5. Turmeric, chilli and cayenne
Spices such as cayenne, chilli and turmeric have a natural warming effect on your body. Cayenne and chilli contain capsaicin, which stimulates blood flow and can give you an immediate feeling of warmth. Turmeric, combined with black pepper, not only increases the absorption of nutrients, but can also create internal warmth.
6. Protein-rich foods
Proteins literally put your body to work as soon as you eat them. They increase the Thermic Effect of Food (TEF), causing your body to produce extra heat during digestion. Both plant-based protein sources such as seitan, tempeh, lentils, chickpeas, pumpkin seeds and hemp seeds, as well as animal sources such as eggs, chicken, fish, yoghurt and cheese provide proteins that aid muscle and cell repair while stimulating your internal heat production.
7. Sweet chestnuts
Sweet chestnuts are a real winter favourite and have a naturally warming effect on the body. According to Traditional Chinese Medicine, chestnuts are good for the circulation, which helps to distribute heat throughout the body. They also contain complex carbohydrates that release energy slowly, fibre for healthy digestion and folic acid, which is important for the formation of red blood cells.
Lifestyle that boosts your warmth
In addition to eating warming foods, exercise acts as your natural heat boost. Activity speeds up your circulation, raises your body temperature and stimulates your lymphatic flow, which helps remove waste products and release energy. Whether you go for a walk, do some stretching or a few jumping jacks, any form of exercise activates your metabolism and acts as a small internal heater.
Internal cold is also exacerbated when your nervous system remains in a constant state of “agitation” due to stress, lack of sleep or insufficient recovery time. Make sure you get enough relaxation and find a way to reduce stress. Because it's not the cold itself, but your ability to regulate your internal rhythm that determines how warm your body really stays.
Prevent blood sugar spikes
To stay warm from the inside out, it is important to keep your blood sugar levels stable. Fluctuations in sugar can cause your energy and body temperature to drop, making you feel cold more quickly. It is also important to eat enough: too few calories can cause your body to reduce its internal heat production in order to save energy. Therefore, choose nutritious, well-balanced meals with sufficient protein, fibre and healthy fats, so that your body has a constant supply of fuel to produce heat and your energy levels remain stable.
Supplements as winter support
In winter, your body can sometimes use a little extra help to support its internal heating processes:
- Vitamin D: plays an important role in supporting the immune system and helps to keep your energy levels stable. This is especially important when the days are shorter and darker, as you cannot produce enough vitamin D due to the lack of sunlight.
- Ginkgo biloba: is known for promoting blood flow, which allows oxygen and nutrients to be transported more efficiently throughout the body and heat to be distributed more effectively.
- Magnesium: relaxes muscles and nerves, reduces tension and helps the body feel and produce heat more effectively.
- Zinc: supports the immune system and recovery processes, allowing the body to use energy more efficiently and better support heat production.
- Turmeric: the active ingredient curcumin can stimulate blood circulation, making energy and heat more readily available to the body.
- Ginger extract: known for its warming properties, it aids digestion and stimulates blood circulation.
Conclusion
Staying warm doesn't have to be a struggle; it's about optimally supporting your body in what it can already do naturally. With a stable metabolism, a calm immune system and the right nutrition that fuels your energy evenly, your body can efficiently generate and retain heat. This creates a powerful, warm rhythm from within that gives you more energy and glow, even on the coldest days.
