Sleep is a naturally occurring state of mind described by altered consciousness, partially inhibited sensory activity, inhibition of nearly all voluntary muscles and a big part of our day. Most people spend one-third of their lives sleeping and still scientists don't fully understand why we need sleep although it is known to help our brains retain information better. Our bodies require long periods of sleep to restore and grow muscle, repair tissue, and synthesize hormones. This is why children grow more over the summer, they also have more time to relax and do not have the stresses of the school year. Many people do not receive the amount of sleep necessary and some even suffer from sleep disorders or parasomnias, such as sleep apnea, narcolepsy, and night terrors. These disorders often disrupt the sufferers sleep cycle, prevent sleep in general, or cause intense nightmares that prompt them to wake up. Besides being able to lay in bed for hours at a time and forget all your problems, sleep is actually very important for you health mentally and psychically. Sleep is involved in the healing of the heart and repair of its blood vessels, lack of sleep is also contributed to a large amount of health problems such as heart disease, kidney failure, stroke, high blood pressure, and diabetes. Without a proper sleeping schedule you might find it harder to pay attention in school or even on the road! Sleeping rests your exhausted brain to prepare it for the next day, a person’s brain that did not receive enough sleep will lose brain cells and not work to its full capacity.

Color Psychology

Colors are powerful communication tools and can be used to signal action, influence mood, and cause physiological reactions. Certain colors have been associated with increased blood pressure, increased metabolism, and eyestrain. However, most colors have different representations depending on one's personal experiences and one's culture. For example, the color white is used in many Western countries to represent purity and innocence, yet it is seen as a symbol of mourning in many Eastern countries. Certain colors even affect your emotions, as well as breathing. The color red, for example, stimulates a faster heartbeat and breathing. The color blue, however, does the opposite in that it relaxes one, slows one's breathing. The color white, as commonly used by doctors, also implies sterility. Color influences perceptions because each color creates a specific type of perceptual capacity or level of intelligence. Often your favorite color might tell you what your favorite mood is and certain colors make you feel a certain way. This is how ads in the markets take advantage of the way certain colors make you feel, and use certain colors to sell you a product. The color Red-Orange is said to be the most appealing color to someone who is shopping for something. Colors were often used in several ancient cultures, including the Egyptians and the Chinese, to heal, through chromotherapy. Chromotherapy is referred to as light therapy or colourology and is still used today as a holistic or alternative treatment. In this treatment: 

Red was used to stimulate the body and mind and to increase circulation.

Yellow was thought to stimulate the nerves and purify the body.

Orange was used to heal the lungs and to increase energy levels.

Blue was believed to soothe illnesses and treat pain.

Indigo shades were thought to alleviate skin problems.
