Normal sweating is the body's way of cooling itself. It's triggered by heat from your environment or from exertion that raises your body temperature. Cold sweats are unrelated to these causes. Sometimes causes of diaphoresis are emergencies, like septic shock or a heart attack. However, cold sweats may also be related to less serious issues and may...
Anything that causes a fight-or-flight response can cause cold sweats. This includes fear, phobias, and anxiety. The fight-or-flight response is triggered when you encounter a situation your body sees as a threat. It allows you to either defend yourself or get away. This is probably the most common cause of diaphoresis.
Your body goes into shockwhen blood flow to the brain and other vital organs becomes dangerously low. That means the brain doesn't get enough oxygen and nutrients. Shock causes increasing body-wide stress.
The flu, COVID-19, and any other infection that causes a fever can lead to cold sweats. Sometimes they occur as a fever "breaks" or starts to go back down. If an infection progresses and enters the bloodstream, the body may go into septic shock.
Severe pain from an injury, like a fracture or non-surgical amputation (losing a body part), can lead to cold sweats. Some medical causes of severe pain, such as kidney stones, can also cause diaphoresis.

Hypoglycemia (low blood glucose/sugar) is a fairly common reason for cold sweats. It's seen most often in people with diabetes or prediabetes.

- Shock. Shock happens when your body reacts to extreme environmental conditions or severe injury. When your body goes into shock, your organs don’t receive as much as oxygen or blood as they need to function.
- Infection or sepsis. Infections can be caused by bacteria or viruses attacking your body’s tissues. In many cases, infections cause your tissues to become inflamed as your immune system tries to fight off the infection.
- Nausea or vertigo. Nausea is simply feeling like you’re sick and going to throw up, although you may not always throw up when you feel nauseous. Nausea can be caused by many things, such as by eating too much or from taking certain medications.
- Fainting. Fainting (syncope) happens when you don’t get enough oxygen to your brain. Cold sweats can occur right before or after you pass out. Fainting because of brain oxygen loss can happen for a number of reasons, including
- Drinking before bedtime. Having a drink or two in the evening may sound relaxing, but it can lead to increased body temperature — and therefore sweating.
- Your stress level. If you're feeling anxious or stressed, you've probably experienced the dread that comes with trying to fall asleep (or back to sleep after waking up).
- Your sleepwear and sleep environment. Everyone likes a cozy sleep environment. But, sometimes, there's a fine line between being cozy and overheating.
