Dr. Rhonda Patrick discusses how research suggests that abstaining from caffeine prior to learning and then consuming it immediately afterward can improve memory retention, and shares tips on how to extract caffeine’s performance-enhancing effects.
New research suggests that cold exposure can reduce waist circumference and abdominal fat, particularly in men, through just two minutes of water immersion up to the neck and five times a week of 30 seconds of cold shower.
Discover the primary sites of heat loss in the human body and how cold showers and ice baths affect them. Learn about the different reasons why people take cold showers and ice baths, from general health to improved resilience and metabolism.
A study explored both immersion in cold water and cold showers and found that brief deliberate cold exposure, involving one session per week of cold immersion in cold water up to the neck for a total of 11 minutes, led to substantial fat loss, particularly around the abdomen.
Cold exposure not only reduces inflammation and improves resilience but also potently increases dopamine and epinephrine levels in the body, according to a study from the year 2000 and subsequent studies.
Using a cold shower for deliberate cold exposure is effective but not nearly as effective as cold water immersion or immersion in ice up to the neck. Challenges arise in studying cold water exposure in the shower, where control over body coverage and head submersion is limited.
