Cold blood from your limbs and skin returns to your core where it mixes with warmer blood thereby causing your deep body temperature to drop, even if you're warmly dressed and move into a warm environment. This is why you often only start shivering 10 to 15 minutes after leaving the water.
Be aware of the signals your body is sending you. If you're feeling lightheaded or dizzy, experiencing intense shivering or feeling any pain, you should get out of the cold water. These are not normal responses to cold water therapy. Pay attention to how you feel during and after your ice bath.
This happens because of vasoconstriction--your body lessens blood flow to your extremities in an effort to preserve core body temperature, and that can make you feel lightheaded when you get out of your ice bath.
Sponging with lukewarm water, about 70°F (21.1°C), may help reduce a fever. Cold water may increase the fever as it can trigger chills. Medicines such as acetaminophen, aspirin, or ibuprofen are helpful in fighting a fever and chills.
Post-ice bath, proper aftercare is essential to maximize benefits and prevent adverse effects: Warm Up Gradually: Slowly warm up your body by wrapping yourself in a towel and drinking a warm beverage. Avoid hot showers immediately after, as sudden temperature changes can be stressful.
Slowly Begin the Warm-up Process: Drying Off and Covering Up
To prevent this, take your time to dry off thoroughly and wear warm, comfortable clothing immediately after the ice bath. Wrapping yourself in a cozy towel or robe and wearing dry socks can help retain body heat and initiate a gentle warming process.
Whether this is additional plunges each morning to help you prepare for the day or after an extra hard-fought workout is up to you, just make sure you listen to your body and avoid overdoing it, as excessive use of ice baths may lead to negative effects, such as decreased immune function and increased muscle soreness.

Dehydration can lead to bad breath, dry or flushed skin, and muscle cramps. Other signs of dehydration could include chills and fever, if dehydration is due to heat illness.
Shivering causes your muscles to contract and relax, which warms up your body. Sometimes you might get cold chills from being exposed to low temperatures. Shivering can also be a sign that your body is fighting off an illness, infection or another health problem.
“An ice bath can cause reduction in blood flow to the extremities in peripheral vascular disease; increase in blood pressure in those with high blood pressure and increased risk of hypothermia in patients with impaired ability to regulate body temperature — as may be the case with poorly-controlled diabetes,” said Dr ...
The cold shock response also increases breathing, heart rate and blood pressure, all of which could pose health risks for people who are susceptible to cardiac events. In addition, when exposed to freezing water and frigid ambient conditions, you can develop hypothermia (dangerously low body temperature) or frostbite.
Regular cold exposure from ice baths can also lead to better sleep. The lowering of body temperature before bedtime can mimic the natural drop in temperature that occurs during sleep, potentially making it easier to fall asleep.
Shivering is not a reliable sign of whether a cold swimmer is okay. Shivering is a way that a body can warm itself up: the involuntary muscle movement is your body's natural response to getting colder and trying to warm up.
Avoid immediate hot showers after a cold plunge to prevent negating the benefits of the cold exposure. If you opt for a shower, gradually increase the temperature. Practice safety and mindfulness throughout your cold plunge and warming routine. Be aware of your body's signals and adjust accordingly.
Start With Short Durations. When first starting, staying in an ice bath for no more than 10 minutes at a time is recommended. This short duration helps your body acclimate to the cold temperature. As your body becomes more accustomed to the cold, you can gradually increase the time spent in the ice bath.
Common causes of tremor include benign essential tremor, nervousness, medication side effects, thyroid hormone disorders or abnormal electrolyte levels (potassium, sodium or calcium).
Most people will shiver for a few minutes as their body warms up. However, if you find yourself shivering uncontrollably for longer than 15-20 minutes after getting out of the cold, it might be a sign that your body is struggling to reheat efficiently. In that case, it's essential to take steps to warm up safely.
After a cold plunge, dry off and warm up by getting dressed in dry clothes. You can sip a warm beverage and move to a heated area. But don't head straight for a sauna or hot tub, because the extreme heat could cause too much stress on your body.
Cold shock response: Sudden immersion in water under 60 degrees can shock your body and lead to symptoms like rapidly increased breathing, heart rate, and blood pressure. This can increase your risk of drowning if you're in deep water. The effect can also strain the heart.
Exposure to extreme cold can cause frostbite, hypothermia, and other injuries. It's important to avoid temperatures below 50°F (10°C) and to listen to your body. If you experience any pain, discomfort, or numbness, it's best to get out of the ice bath immediately.
Remember: Staying in an ice bath too long can lower your core body temp too much, which is also risky. So, don't go beyond that five-minute limit. “In sports medicine, ice baths are used for marathon runners and others who are experiencing heat injuries,” Dr. King explains.
Taking a cold plunge in an Ice Barrel can activate the brown adipose and muscles in your body. Once activated, irisin and FGF will be released (irisin and FGF are cold-induced endocrine activators of brown fat function in humans). These two hormones burn up the white fat tissues resulting in weight loss.
