Why Do I Get Really Cold After a Workout?

It’s normal to feel cold after a workout. Learn why this happens and how you can prevent it.

Exercise and Temperature Regulation

Many people find that after a workout, their body temperature can drop drastically, leaving them feeling extremely cold. This is a common phenomenon that can occur due to a variety of factors. Before we delve into the science behind temperature regulation after exercise, let’s discuss why this happens and what can be done to prevent it.

How exercise affects body temperature

Regular exercise has many health benefits, but it can also take a toll on your body temperature. During physical activity, the body produces more heat than what it can dissipate through its normal mechanisms of cooling. As a result, the core temperature of your body increases and you may experience a drop in body temperature shortly after exercise.

The duration of the decrease in body temperature after exercise depends on different factors such as intensity of activity and environmental conditions like air temperature, relative humidity or wind. The heat produced during rigorous activity can persist for minutes to hours after exercise is stopped due to several physiological adaptations that take place including an increase in heart rate and sweating as well as improved blood circulation to the skin.

After sustained physical activity, there will be an unavoidable decline in core body temperature as your system works to maintain homeostasis; however, there are steps you can take to minimize this cooling period. The most important thing is to drink enough fluids before and during a workout so that dehydration does not impede your cooling mechanisms. Additionally, wearing appropriate clothing for the level of physical exertion and environmental conditions may help reduce your risk of suffering hypothermia post-exercise by trapping heat within the layers closest to your skin while allowing evaporative sweating to occur at more distant layers.

The role of sweat in cooling the body

During exercise, the body produces heat and needs to find a way to keep its temperature regulated. Sweat is one of the most important ways our bodies dissipate this heat. Through a process called evaporative cooling, sweat helps reduce the body’s core temperature by lowering its surface temperature. As sweat evaporates from the skin, it pulls some of that heat with it and carries it away from your body, cooling you in the process.

However, as sweat evaporates from your body during a workout, you are also losing much-needed water and electrolytes, which can lead to dehydration if not replaced properly. After a workout, it’s important to replenish fluids and electrolytes so that your body stays hydrated allowing it continue to cool itself properly through sweat when needed.

Dehydration can lead to an increase in body temperature which causes the body’s thermoregulatory system to kick into high gear in order to maintain homeostasis of the core temperature. In order compensate for any increase in internal temperatures due to dehydration or other factors – such as environmental conditions — sweat may be released more quickly or at greater levels by becoming more profuse creating even more evaporative cooling at the surface of the skin leading to a visible chill indicating temperatures well below what they should be under normal circumstances. Therefore keeping yourself hydrated between workouts goes beyond just quenching thirst but may also help in avoiding excessive cold experiences when engaging in regular exercise activity.

Causes of Post-Workout Chills

Post-workout chills can be more than just an uncomfortable experience. It can be a sign of something more serious. These chills can be linked to dehydration, muscle fatigue, and even hypothermia. It is important to pay attention to post-workout chills and figure out the root cause so that you can address it properly. This article will delve into some of the common causes of post-workout chills.


One of the primary causes of post-workout chills are dehydration. Working out, especially when it’s strenuous, burns a lot of calories and can cause your body to heat up. To help cool itself down, your body works hard to sweat more and lower its temperature – this process requires an ample amount of water. If you are not supplying your body with enough water, it won’t be able to bring its temperature back down as efficiently. Consequently, you may experience post-workout chills and even shivering as your body temperature falls rapidly and attempts to regain control over its core temperature. It is important that you drink plenty of fluids before, during and after exercise – water is essential for the proper functioning of your fluid levels in order to get rid of waste products like lactic acid from intense activities and remain hydrated after exercise.

Poor circulation

Poor circulation is one of the most common causes of post-workout chills. Poor circulation occurs when the body does not have sufficient blood flow to reach areas that need it most. This can be due to a variety of factors, such as dehydration, poor nutrition, and even stress. When circulation is impaired, the body will take energy away from muscles and other parts of the body in order to keep critical organs functioning normally. This can lead to lower core temperatures which can cause uncomfortable chills after exercise.

To avoid this problem, it is important to maintain proper hydration during exercise and afterwards by drinking plenty of fluids before, during and after workouts. It is also important to eat adequate amounts of carbohydrates before and after intense physical activity in order to promote better circulation throughout the body. Additionally, keeping track of stress levels before a workout may help improve overall performance because high levels of stress hormones can inhibit proper circulation. Finally, appropriate warm up and cool down sessions may also be useful for avoiding post-workout chills by properly temperature regulating the body prior to or following strenuous physical activity.

Poor insulation

When exercising, our bodies produce heat which the body then responds to by increasing circulation to the outer covering of the skin, known as vasodilation. During this process, our body starts to sweat and evaporate into the air; a process which is essential in maintaining a safe temperature for muscular activities. This works with our clothing and environment, known as insulation, helping us regulate our core body temperature effectively. Poor insulation can lead to post-workout chills – when you don’t have enough layers of clothing or you’re exercising outdoors in cold weather conditions where your sweat is not able to evaporate and keep you warm. Poorly insulated clothes will allow your sweat’s heat to escape quickly resulting in low temperatures and chills. In addition, cutting time on warming up prior exercise leads to a lower body temperature during exercise, this making cooling down stage more severe and can cause post-work out shivers.

Prevention Tips

Many people experience feeling cold after intense bouts of physical activity, and this chill can be largely attributed to the body switching from its hot and sweaty workout mode to its cool-down mode. To avoid feeling chilled after exercising, it’s important to be mindful of the preventive measures you can take. In this section, we’ll discuss some of the tips and strategies that you can implement to limit the coldness after a workout.

Stay hydrated

Staying hydrated is key to staying warm during and after exercise. Dehydration can lead to lower body temperatures, shivering, and even exhaustion in extreme cases. Aim to stay hydrated before, during, and after a workout by ensuring you are drinking the recommended amount of water throughout the day.

In addition to water, consider adding an electrolyte-replacing drink or sports drink like Gatorade or Powerade to your routine. Electrolyte drinks contain additional benefits such as sodium, magnesium, phosphorus and potassium that are lost in sweat. In cold weather conditions especially, these drinks can replenish vital minerals needed for muscle contraction.

Adding a side of broth or soup with meals can also be beneficial when it comes to restoring lost electrolytes from exercise. Nutrient-rich broths are particularly significant for staying warm and exercising in cold temperatures as the chicken bone broth used helps ward off muscle cramps during workouts – when combined with water it is also a great source of hydration afterwards!

Wear layers

Wearing layers allows you to regulate your core temperature more easily when you exercise. Just make sure you don’t overdress by choosing materials that are too thick. Synthetic or natural fibers are both good options but avoid cotton – it tends to stay damp and quickly loses its insulation properties when wet. Start with a lightweight base layer like merino wool, which can provide excellent temperature control and is naturally odor-resistant, then add some layers of breathable clothing items like synthetic or wool mid layers to hold in body heat during the cool-down phase of your workout. Consider finishing off with a lightweight windproof jacket or vest to protect against any sudden winds or drops in temperature.

Warm up before exercising

Having a good warm up before exercising can go a long way in preventing body temperature from dropping too low after a workout. Proper warm up not only helps in reducing the risk of injury but also increases flexibility of muscles, prepares the body for adequate energy supply and helps to bring the core temperature up. Therefore, it is important to warm up prior to exercising. A short 5-10 minute aerobic activity with at least one dynamic stretching exercise involving both upper and lower body muscles should do suffice for any type of activity. Moreover, during extreme cold weather, doing low intensity exercise/warm up inside before heading outdoors is highly recommended, as it ensures that when you go outdoors your core temperature has already increased and won’t drop drastically after strenuous exercise.

When to See a Doctor

For most people, feeling cold after a workout is nothing to worry about. However, there are certain instances where you should see a doctor. This article will provide advice for when it is necessary to seek medical attention for feeling cold after exercise. Knowing the signs of something being wrong is essential for your health, so let’s get into the details.

Signs of hypothermia

Although it is normal to feel a bit cool when you stop exercising, if your body temperature drops dangerously low and remains low after 30 minutes, you may be experiencing hypothermia. Some signs to look for if you feel that you may be developing hypothermia include:
-Shivering; extended periods of shivering that don’t pass with rest or wrapping up in a warm blanket should be monitored.
-Thin skin; if your skin feels paper thin and raw to the touch, it’s time to take action.
-Lightheadedness or confusion; feeling faint or having problems focusing can be signs of hypothermia as well.
-Unusual tiredness; feeling excessively tired even though you have normal energy levels can also be symptoms of hypothermia.
It is important to contact your doctor as soon as possible if you experience any of the above symptoms after a workout. Prompt diagnosis is essential, as hypothermia can lead to serious health complications such as organ failure and even death in some cases, especially when left untreated for too long. Your physician can assess your situation and recommend an appropriate course of treatment should your condition progress significantly during this time period.

Excessive shivering

Excessive shivering after a workout can be a sign of illness or another underlying medical problem. While most people expect to experience some level of shivering during or after a workout due to the release of endorphins and higher metabolism, it should not be severe enough to disrupt everyday activities. If you find that you are shivering after working out for longer than 20 minutes, it may be time to see a doctor.

Shivering is often caused by excessive cold, as one’s core temperature drops in order to regulate heat production while exercising. In these cases, pre- and post-workout warm-up exercises such as stretching and foam rolling can help keep the body warm. It is also important to stay hydrated throughout your workout in order to preserve body heat more effectively.

However, if you have already taken these steps and still find yourself shaking excessively afterwards, it could be the result of an underlying medical condition such as hypothermia or anemia. Additionally, if the onset is sudden and severe then it could also signal an infection or other serious health issue such as thyroid problems or nerve damage from prolonged cold exposure.

If you experience any of these symptoms following exercise, it is important that you reach out for medical assistance immediately in order to properly diagnose and treat your condition before it worsens further.

Feeling faint or dizzy

If you feel faint or dizzy after a workout, it is best to seek medical attention immediately. This could be a sign of dehydration but it could also indicate more serious conditions such as low blood sugar and heat exhaustion. Additionally, long-term fatigue or pain while exercising could be an indication of a more severe underlying condition, such as anemia, which requires medical attention.

It is important to note any other symptoms that you may have experienced prior to feeling faint or dizzy such as shortness of breath, chest pain, and/or anxiety. This can help create a clearer picture for your doctor when evaluating your condition and how best to treat it. In some cases, simple changes in regimen such as hydrating properly before exercise or slowly increasing the intensity may be enough to resolve the issue. However if your symptoms persist, then further testing and diagnosis may be necessary.
