This metabolic demand makes brain cells particularly vulnerable to damage from oxidative stress, in which reactive oxygen species (ROS), sometimes called free radicals, exert toxic effects on cellular components.

Now researchers reporting in the Cell Press journal Neuron on July 18 show in a study conducted in rats that even a single exposure to nicotine temporarily changes how the brain's reward system responds to alcohol and increases the reinforcing properties of alcohol via stress hormones.

Three recent experimental studies focused on low consumption / exposure.949596 In one study, 29 smokers each consumed a single cigarette, immediately after which they had a significant decrease in blood vessel output power and significant increase in blood vessel ageing level and remaining blood volume 25 minutes later, as markers of atherosclerosis.94 In another study, human coronary artery endothelial cells were exposed to the smoke equivalent to one cigarette, which led to activation of oxidant stress sensing transcription factor NFR2 and up - regulation of cytochrome p450, considered to have a role in the development of heart disease.95 These effects were not seen when heart cells were exposed to the vapour from one e - cigarette.95 A study exposed adult mice to low intensity tobacco smoke (two cigarettes) for one to two months and found adverse histopathological effects on brain cells.96

In a preliminary study, researchers found that compounds in black currants helped protect brain cells from stress brought on by Alzheimer's - associated proteins.

In this episode Rhonda talks about how heat stress from using the sauna makes the body more resilient to the stresses of aging, possible reasons why one study associated sauna use with up to a 40 % lower all - cause mortality as well as a 50 % lower cardiovascular disease related mortality, how it enhances athletic endurance, staves off muscle atrophy, improves regrowth of muscle after disuse, and some of the profound effects on the brain, including the growth of new brain cells, improvement in focus, learning, and memory, and even potentially ameliorating depression and anxiety.

These foods increase blood flow to the brain and protect brain cells from oxidative stress and also decrease the effects of age - related conditions like dementia and Alzheimer's (study on blueberries and Alzheimer).

They also tend to smile more, be friendlier, and because their brains are better equipped to deal with stress, there is less silent impact on their cells (i.e. inflammation, oxidation / free radical damage), and therefore their outward appearance is more naturally beautiful.
