How should I approach cold showers to accelerate my metabolism?

To use cold showers to accelerate your metabolism, here are some key points from Huberman Lab:

1. Activation of Brown Fat: Cold exposure stimulates brown fat, which is crucial for increasing metabolism. Brown fat helps maintain body temperature by burning calories, contributing to weight loss and enhanced metabolic function 1 2.

2. End on Cold: According to the Søberg principle, ending your cold exposure with cold (and not transitioning to heat immediately afterward) can maximize metabolic benefits. Allowing your body to reheat naturally after cold exposure encourages metabolic processes like shivering, which further boosts metabolism 2.

3. Inducing Shivering: Aim to reach a point of mild shivering. Shivering releases a molecule called succinate, which activates brown fat and enhances thermogenesis, leading to increased metabolism. You can achieve this by alternating between cold exposure and air drying, making sure your limbs are extended to further encourage shivering 2.

4. Duration and Frequency: A routine of cold showers for short bursts (30 seconds to a few minutes) is recommended. The water should be uncomfortably cold, yet safe enough for you to endure. Gradually increase exposure time as your tolerance improves.

5. Safety Precautions: Approach cold exposure safely and gradually, starting with warmer temperatures if necessary until you build tolerance. The recommended water temperature ranges between 37°F to 55°F, depending on individual comfort and safety 3.
