What happens when you take too much caffeine - When we consume caffeine, it's quickly absorbed into our bloodstream, where it out-competes adenosine by preventing it from connecting to these receptors and doing its job to make us feel tired. This is why consuming caffeine can make us feel more awake and alert. Caffeine can also boost levels of other neurotransmitters like dopamine and adrenaline, which can make you feel more stimulated. Research has associated caffeine consumption with up to a 60% reduced risk of developing Alzheimer's. One explanation for this is that caffeine improves blood flow to the brain. While caffeine enters the gut quite quickly, its effects can take hours to wear off. Scientists recommend having your last 'dose' of caffeine eight hours and 48 minutes before you go to bed.

Why do 1 in 10 Americans get eczema? Is it too much salt? - Eczema, also known as atopic dermatitis, is a chronic disease that causes dry, itchy skin.

It has become increasingly common in recent years, especially in industrialized countries, implicating environmental and lifestyle factors like diet.

Depressive symptoms may hasten memory decline in older people – 16 years of data from 8,268 adults with an average age of 64. This study shows that the relationship between depression and poor memory cuts both ways, with depressive symptoms preceding memory decline and memory decline linked to subsequent depressive symptoms. So – interventions to reduce depressive symptoms might slow memory decline.
