1. People Get Sick More Often in the Winter : A leading theory is that confinement breeds infection. We spend more time indoors, in rooms that may not get a lot of circulation, giving us more opportunities to be exposed to respiratory viruses. The winter air, inside & outside, also tends to be less humid, drying nasal passages & making them more vulnerable to viral invasion. The cold environment itself has not been proven to make people get sick in the winter.

2. Causes of Joints Crack : When you stretch a joint by, say, pressing down on your knuckles or twisting your spine, you cause small air bubbles that form between the sacs in the joints to pop. These sacs, called bursas, help cushion the spaces between the bones & keep them lubricated. As creepy as the sound can be, cracking is usually harmless & has no effect on the bursas. Despite what your mom may have told you, cracking your knuckles or ankles or knees or any other joint doesn’t cause arthritis.

3. Causes of Hiccups : Excessive eating, alcohol, excitement, or stress can over stimulate the phrenic nerves, which control the diaphragm. The diaphragm then contracts involuntarily. At the same time, the glottis, the part of the larynx where the vocal cords are located, closes up. The result is the spasms and the odd hic sound that repeat every few seconds. A typical case of the hiccups lasts only a few minutes, but some can last much longer. While there’s no proven cure.

4. Causes of Earwax : To keep foreign matter from invading ear canals. Earwax, or cerumen, is produced by glands in the outer ear to protect the inner ear from infection. The sticky substance prevents dust, dirt & bugs from getting in. The wax slowly moves up & out of the ears on its own, dries up & flakes off or washes away when you shampoo your hair. If you’re a Q-tip addict, clean just the outside of your ears.

5. Causes of teens sleep Late : During childhood, melatonin, the hormone that regulates the wake-sleep cycle, is secreted by the pineal gland early in the evening. When puberty hits, from around ages 10 to 14, melatonin is released later, around 9 p.m. or 10 p.m. This shift often makes many teenagers incapable of falling asleep before 11 at night. Since teens still need about nine or more hours of sleep, they try to make up for the time they’ve lost at night by sleeping in.

6. Causes of Whiter teeth : Just like the color of your eyes and hair, the natural tint of your teeth is hereditary. Some people have very white enamel the thin coating on the surface of teeth while other people’s enamel has a more yellow hue. They tell a lot about a person’s health & history. Taking the antibiotics tetracycline or amoxicillin as a child can affect the calcification process, causing discoloration. Certain foods can also darken teeth. Coffee, tea, cola, and red wine are common culprits. Frequent cleanings can help, but severe food stains may require a whitening product or procedure
