WHY DOES CHOCOLATE CAUSE ACNE?

Why does chocolate cause acne?

•Chocolate does not cause acne. Acne is caused by overactive sebaceous glands.

•Sebaceous glands are microscopic glands connected to the hair follicles.

•Their job is to secrete skin oil (sebum), which travels up the shaft of the hair and out onto the skin in order to waterproof the body.

•If the glands secrete too much skin oil, the channel along the hair's shaft becomes clogged.

•As a result, a buildup of skin oil and dead cells occurs in the glands and the hair follicle.

•This stagnant, clogged mass just below the skin's surface becomes infected with bacteria and turns into a pimple.

•Sebaceous glands accelerate their secretions in response to high levels of sex hormones, such as present during puberty.

•The causes of acne are therefore: 1) elevated sex hormones, 2) sebaceous glands that are overly sensitive to sex hormones, and 3) the presence of bacteria that take advantage of the situation.

•Chocolate has no effect on acne, according to a study done by scientists.

•Scientists divided 65 subjects with mild acne into two groups; one group had people eating chocolate bars, and the other had people eating bars that looked like chocolate but contained no chocolate.

•In the end, there was no difference in the acne of the two groups. Though chocolate does not affect acne, anything that raises the levels of sex hormones will worsen acne.

•For example, using testosterone replacement therapy to boost abnormally low testosterone levels can worsen acne.

•For women, menstruation leads to fluctuations in hormone levels and can therefore worsen acne.

•Because of the three factors that combine to cause acne, various treatments work by addressing one or many of these factors. Some treatments lower sex hormone levels, while others kill the bacteria. Also, some treatments work by widening the follicle shafts to reduce blockage.

HOW CAN WE MOTIVATE OURSELVES MORE EFFECTIVELY THROUGH REINFORCEMENT?

•We'd all like to be more effective in reaching our goals, and according to behaviorists, the way to improve our effectiveness is by rewarding ourselves for the little steps that take us closer and closer to those desirable outcomes. •First, find something you really like to do or something you'd like to have that can, realistically, serve as a reward. •Then, take the goal that you are hoping to achieve that, realistically, you could achieve but just haven't succeeded at yet. •Next, work backward from that goal to your present state. •Arrange to give yourself those desired rewards as you inch closer from where you are now to the desired end point. •As you start to make progress, only give yourself a reward when you've moved forward from where you are now. •For example, if you'd like to cut back on your television watching and instead read more often, reward yourself by allowing yourself to watch television only when you've read for 20 minu...

WHY DO WE SLEEP AND DREAM?

•We spend about one-third of our lives sleeping. •Why do we invest so much time in sleep? •The most straight forward answer is that, sleep is restorative, and it replenishes the body's energy stores. •However, intense neural activity during rapid eye movement (REM) sleep, the stage in which most dreams occur, suggests there may be more to the story. •One theory, which by far has the largest body of evidence, is that sleep plays a critical role in learning and consolidating memories. •It is probably why infants and toddlers need up to 14 hours of sleep a day, with half of it spent in REM sleep. •In adults, dreams may also play a role in brain plasticity and learning, which is why sleep-deprived adults perform worse in memory tests and tasks.

Clouds are just water vapor, so why do they move?

Clouds are just water vapor , so why do they move ? •Clouds are not water vapor. Water vapor is the gas state of H 2 O and is invisible. •The air around you on a humid summer day is chock full of water vapor, but you don't see any of it. •On the other hand, there is very little water vapor in the air during the cold of winter, yet you can easily make clouds with your breath. •Clouds are collections of liquid water droplets or ice that are small enough to float. •When the water vapor in the air gets cold enough, it condenses back into liquid in the forms of droplets. •But the condensation is not automatic. It takes a bit of matter – a condensation nucleus – in order to jump start the process. Dust, salt, and ice in the air do the trick by providing a surface for the water to condense on to. •Clouds are white because the water droplets making the cloud are the right size to scatter light resonantly according to Mie scattering. •Mie scatte...
