Afterdrop: Why You Keep Getting Colder After a Cold Plunge
Afterdrop is the phenomenon where your core body temperature continues to fall after you've already gotten out of cold water. You step out of a 40F cold plunge expecting to warm up immediately, but instead you feel colder for another 10-20 minutes. That's afterdrop, and understanding it is essential for anyone practicing cold water immersion.

Why Afterdrop Happens
During a cold plunge, your body pulls blood away from your skin and extremities to protect your vital organs. This is vasoconstriction at work. Your cold skin and outer tissues act like a refrigerated shell around a still-warm core.
When you exit the water, your blood vessels begin to reopen. That cold blood sitting in your extremities now flows back toward your core, mixing with warmer blood and pulling your internal temperature down. Your core temp can drop another 1-3F after exiting, even while you're toweling off and putting on warm clothes.
How Long Does Afterdrop Last?
For most people doing standard cold plunge sessions of 2-5 minutes at 40-50F, afterdrop lasts roughly 10-20 minutes. The colder the water and the longer you stayed in, the more pronounced the afterdrop. You'll typically notice shivering intensify after getting out, which is your body's way of generating heat to fight the temperature dip.
Managing Afterdrop Safely
Don't panic when you feel colder after exiting. This is normal. Do not jump into a hot shower or sauna immediately - the rapid temperature swing can cause dizziness or blood pressure issues. Instead, dry off, put on warm layers, and let your body reheat naturally. Light movement helps. Shivering is your friend here; it's remarkably effective at generating heat.
If you practice contrast therapy, give yourself at least 5-10 minutes between cold plunge and sauna to let afterdrop stabilize. Experienced cold plungers learn to factor afterdrop into their routine and actually welcome the post-plunge shiver as a sign their noradrenaline response kicked in properly.
