Related Episodes for How Evening Sauna Use May Support Sleep

“The mechanisms that drive the effects of sauna bathing include activation of heat shock proteins and pro- and anti-inflammatory cytokines; decreased blood pressure and arterial stiffness; and multiple improvements in cardiovascular function.”

“A common feature of heart disease is arrhythmia, an irregular heartbeat. Interestingly, research in fruit flies has shown that unhealthy lifestyle behaviors, such as poor sleep and diet, increase the risk of developing arrhythmias.”

“- Practical details like temperature and duration of sauna use, the difference between a dry, wet and infrared sauna, sauna timing, as well as other forms of heat stress such as steam showers, hot baths, and hot yoga.”

“Practical exposure reduction can include avoiding heat with unsuitable plastic, using glass or stainless steel for hot foods and drinks when convenient, replacing damaged containers, and choosing fragrance-free personal-care products when feasible.”

“Bright light exposure has a profound effect on regulating the circadian system in humans. Dr. Panda and colleagues discovered that melanopsin — a light-sensitive protein found in specialized cells of the eye — responds to blue light and synchronizes the body's day/night cycle.”

“The most compelling human signal appears when the brain is under acute strain. In a randomized crossover study, a single dose of 0.35 grams per kilogram during 21 hours of sleep deprivation changed cerebral energy metabolites and preserved selected measures of cognitive performance.”

“A recent meta-analysis also found small benefits in selected cognitive domains, including memory and processing speed, with responses that may depend on age, diet, baseline stores, stress, dose, and the cognitive test used.”

“Acute stress may create a different context. In a double-blind crossover study of 15 adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed brain high-energy phosphate measures and improved selected cognitive outcomes.”
