Morning cold shower

Taking a morning cold shower has several benefits according to Andrew Huberman. Here are the key points:

1. Increased Alertness and Metabolism:

   • Cold showers can provide a significant spike in adrenaline, cortisol, and dopamine, which helps you feel more awake and alert in the morning. The dopamine increase from cold exposure can be quite substantial and long-lasting, providing sustained energy and alertness throughout the day 1.

2. Boosted Dopamine Levels:

   • A very cold shower or cold plunge for 30 seconds to two minutes can boost dopamine levels, enhancing mood and focus for hours 2.

3. Thermogenic and Metabolic Effects:

   • Your body reacts to cold water by increasing internal heat production, which can boost your metabolism. This is akin to turning up a thermostat, ensuring your core body temperature rises 1.

4. Improving Wakefulness and Circadian Rhythm:

   • Cold showers in the morning help phase advance your biological clock, making it easier to wake up early the next day. This effect is due to the rapid rise in body temperature after the cold exposure 3.
