Sleep and Body Temperature
Deliberate cold exposure can elevate mental benefits significantly, but the role of body temperature in sleep is crucial. Heating the body surface prompts a cooling of core temperature, facilitating the drop needed for sleep. Understanding the interplay of temperature and circadian rhythms can optimize workout times and enhance overall well-being.In this clip

I have a question about the episode Joe Rogan Experience #1958 - Andrew Huberman and the clip Cold Exposure Benefits. There are conflicting opinions about the effects of cold showers on energy levels and sleepiness. Dr. Huberman recommends taking cold showers early in the day to promote hormone release and increase body temperature, which should make you feel energized. However, some sources suggest that while there is an initial increase in body temperature, it may drop afterward, leading to sleepiness. Others argue that the expansion of blood vessels may cause a feeling of sleepiness despite an initial warming effect. What is the scientific evidence supporting these claims?
How does raising body temperature (e.g. by going to the sauna or taking a long hot bath) influence sleep, as discussed in the episode Dr. Matthew Walker on Sleep for Enhancing Learning, Creativity, Immunity, and Glymphatic System and the clip Sleep and Temperature?
What effect does a cold shower in the evening have on sleep schedule as discussed in the Huberman Lab Podcast episode "Using Science to Optimize Sleep, Learning & Metabolism | Huberman Lab Podcast #3" and the clip "Cold Exposure Benefits"?
