Feeling cold every afternoon is a common experience, and it usually comes down to how your body manages its temperature throughout the day. Your internal thermostat follows a natural rhythm, and for many people, that rhythm dips in the late afternoon. In most cases, this is a normal bodily response, but sometimes it can point to an underlying issue worth discussing with a doctor.
Why Do I Get Cold Every Afternoon Causes Fixes?
Your body temperature is not a fixed number. It rises and falls in a predictable 24-hour cycle called the circadian rhythm. For most people, temperature peaks in the late afternoon or early evening and reaches its lowest point in the early morning hours before waking.
Feeling cold in the afternoon can happen when your body’s core temperature starts to drop as part of this natural cycle. This drop signals your blood vessels to narrow, which reduces blood flow to your skin and extremities. That reduced blood flow is what makes your hands and feet feel cold, even if the room is warm.
Another common reason is what you ate for lunch. Digestion redirects blood flow to your stomach and intestines. This shift can leave your skin and limbs with less warm blood, making you feel chilly about an hour or two after a meal.
Fatigue also plays a role. When you are tired, your metabolic rate can slow slightly, and your body produces less heat. If you are physically active in the morning but sedentary in the afternoon, your heat production drops, and your body may struggle to keep you warm.
What Is a Normal Body Temperature Range?
A normal resting body temperature for a healthy adult is generally accepted as around 98.6°F (37°C), but that is an average, not a strict rule. Individual normal temperatures can range from about 97°F (36.1°C) to 99°F (37.2°C).
Your temperature can vary by as much as 1°F (0.5°C) over the course of a day. It is typically lowest in the early morning and highest in the late afternoon. This means a temperature that feels normal in the morning might feel cold to you in the afternoon, even though it is not clinically low.
Feeling cold is not the same as having a low body temperature. A true low body temperature, called hypothermia, is defined as a core temperature below 95°F (35°C). That is a medical emergency. What most people describe as “feeling cold” in the afternoon is a perception of cold, not a dangerously low core temperature.
Can Low Blood Sugar Make You Feel Cold?
Yes. Low blood sugar, also called hypoglycemia, can make you feel cold and shaky. This is because your brain and body rely on glucose for energy, including heat production. When blood sugar drops too low, your body cannot generate heat as efficiently.
This often happens in the mid-to-late afternoon, especially if you ate a lunch heavy in refined carbohydrates. Foods like white bread, pasta, or sugary snacks cause a rapid rise in blood sugar followed by a sharp drop a few hours later.
Other symptoms of low blood sugar include sweating, irritability, dizziness, and difficulty concentrating. If you notice these symptoms along with feeling cold, eating a balanced snack with protein and fiber may help. If symptoms are severe or you have diabetes, check your blood sugar and follow your doctor’s guidance.
Could Anemia Be the Reason You Feel Cold?
Anemia is a condition where your blood does not carry enough oxygen to your body’s tissues. This can happen because of low iron, low vitamin B12, or low folate. Without enough oxygen, your body’s cells cannot produce heat efficiently, and you may feel cold even in warm environments.
Anemia is more common in women of childbearing age due to menstrual blood loss. It is also common in people with digestive conditions that affect nutrient absorption, such as celiac disease or Crohn’s disease.
Other signs of anemia include fatigue, pale skin, shortness of breath with mild activity, and dizziness. If you regularly feel cold in the afternoon and have any of these other symptoms, a simple blood test can check your hemoglobin and iron levels. This is a common test that your doctor can order.
What Role Does Your Thyroid Play?
Your thyroid gland produces hormones that control your metabolism. These hormones tell your body how fast to burn energy and produce heat. When your thyroid is underactive, a condition called hypothyroidism, your metabolism slows down. This can make you feel cold all the time, including in the afternoon.
Hypothyroidism is more common in women and becomes more likely with age. Other symptoms include weight gain without changes in eating, dry skin, constipation, and fatigue. Feeling cold is one of the most commonly reported symptoms.
A blood test measuring thyroid-stimulating hormone (TSH) can screen for this condition. If your thyroid is underactive, prescription medication can replace the missing hormones. Most people notice improvement in cold sensitivity within a few weeks of starting treatment.
Are You Simply Dehydrated?
Dehydration can make you feel cold. Water helps regulate your body temperature by distributing heat through your bloodstream. When you are dehydrated, your blood volume drops, and your body prioritizes keeping your core organs warm over your skin and extremities.
Many people are mildly dehydrated in the afternoon without realizing it. They may have had coffee in the morning, skipped water breaks, and eaten a salty lunch. By mid-afternoon, the cumulative effect can leave you feeling chilled.
Signs of dehydration include dark urine, dry mouth, headache, and fatigue. If your afternoon chill comes with these symptoms, drinking a glass of water and seeing how you feel within 30 minutes is a reasonable first step.
When Should You See a Doctor About Feeling Cold?
Occasional afternoon chills are usually nothing to worry about. But there are situations where feeling cold warrants medical attention.
See a doctor if your cold feeling comes with any of these:
- Fever above 100.4°F (38°C)
- Shaking chills that do not stop
- Numbness or color changes in your fingers or toes
- Unexplained weight loss
- Fatigue that interferes with daily activities
- Shortness of breath or chest pain
These symptoms could indicate an infection, a circulatory problem, or another condition that needs evaluation. Do not ignore them or assume they will pass.
Simple Ways to Warm Up in the Afternoon
If your afternoon chill is mild and you have no other symptoms, a few simple strategies can help.
Dress in layers. A light sweater or jacket that you can remove and put on as needed is more practical than a heavy coat. Your body temperature fluctuates, so adjustable clothing helps you match your environment.
Move your body. A short walk, even around your office or home, increases blood flow and generates heat. Five to ten minutes of movement can make a noticeable difference.
Drink something warm. Warm liquids raise your core temperature temporarily and can take the edge off the chill. Tea, warm water with lemon, or broth are all good options. Avoid caffeine late in the day if it affects your sleep.
Eat a balanced lunch. Include protein, healthy fats, and complex carbohydrates. This combination keeps your blood sugar steady and provides sustained energy for heat production through the afternoon.
Check the room temperature. If your workspace has air conditioning, the temperature may be set cooler than your body prefers. A small space heater or a blanket over your lap can help without affecting your coworkers.
Frequently Asked Questions
Is it normal to feel cold every afternoon?
Yes, it is often normal. Your body temperature naturally dips in the afternoon as part of your circadian rhythm, and this can make you feel cold even in a warm room.
Can what I eat for lunch make me feel cold?
Yes. A lunch high in refined carbohydrates can cause a blood sugar drop a few hours later, which can make you feel cold and tired.
What medical conditions cause feeling cold in the afternoon?
Anemia, an underactive thyroid, and dehydration are common causes. If you have other symptoms like fatigue, pale skin, or weight gain, talk to your doctor about blood tests.
Should I take my temperature if I feel cold in the afternoon?
It can help. If your temperature is above 100.4°F (38°C), you may have a fever and should monitor for other signs of illness. If it is normal, the cold feeling is likely due to your body’s natural rhythm.
Feeling cold every afternoon is rarely a serious problem. It is usually your body following its natural daily rhythm or responding to what you ate, drank, or did earlier in the day. Pay attention to other symptoms, stay hydrated, and dress in layers. If the cold feeling comes with fatigue, weight changes, or other concerning signs, a blood test can help rule out conditions like anemia or thyroid problems.
