Fast Fact
One of the great wonders of the human body is the ability of damaged cells to be repaired or replaced. Red blood cells, for instance, live for about 120 days. Each day, about 1% of your red blood cells retire to be replaced by a fresh generation. The lens of the eye is a notable exception. The cells of the lens of the eye are never replaced; the proteins of the lens are never replenished. The lens cannot repair itself; damage accumulates over a lifetime.
Cataracts are the result of gradually accumulating damage to the proteins of the lens. The most important source of this damage is exposure to ultraviolet (UV) radiation, especially while one is young.
Behind the lens lies the retina, the thin lining of the back of the eye. The retina is the eye's miracle. This patch of tissue, about the size and thickness of a postage stamp, is able to dissolve and create a new image every tenth of a second.
Today in the United States, retinal diseases are the leading cause of blindness. Macular degeneration, the accumulation of damage in the retina, is the leading cause of blindness from retinal disease. Slowly, over the years, the macula is irreversibly damaged by exposure to UV radiation. About one third of adults over age 65 experience this steady decline of central vision, not correctable by glasses.
Excessive exposure to sunlight during early childhood is harmful to the eyes. Sunlight contains harmful UV radiation.
The risk for retinal damage from the sun's rays is greatest in children less than 10 years old, although the consequences usually do not become apparent until well after they are adults.
All children should be taught to wear sunglasses, especially between 10 AM and 2 PM, when ultraviolet exposure is the most dangerous. This is true even for children with darker eye colors, even though their darker pigments afford partial protection. Of course, children with light-colored eyes need sunglasses all the more.
Ultraviolet exposure is at its peak when children are at high altitudes, snow-covered landscapes, bright sandy beaches, or near reflective bodies of water.
All sunglasses are not the same. Effective sunglasses should block both UVA and UVB radiation. The sunglasses must be measured to block 99% to 100% of UVA or UV400 (400 nm is the wavelength of UVA radiation). Thankfully, all sunglasses block UVB radiation.
Large lenses that fit close to the eyes are best. Those that block visible blue light are even safer.
Expensive brand names and polarizing lenses are no guarantee.
Ordinary sunglasses make the situation WORSE! The dark lenses cause the pupils to dilate, allowing more of the dangerous UVA radiation to damage the lens and the retina.
Many families throughout history have chosen a "family bed." In fact, in most cultures around the world today, a "family bed" is the norm. If that is a family's choice, it can work very well. However, having a "family bed" is not for everyone. It also works well to teach children to sleep in their own beds. Here are some tips on how to help children sleep in their own beds:
It does not work well to tell children to sleep in their bed and then relent when they act up. This only teaches them that their persistence will be rewarded with a trip to your bed.
The best approach is to discover the underlying cause or causes for your child's behavior. At some level, your child knows why she doesn't want to sleep in her own bed, even if she isn't able to articulate what she is feeling. If you ask her outright what she is feeling, you may not get any valuable information.
A great way of discovering what your child is feeling is to play with her using dolls or action figures to represent members of a family. Have the characters act out several typical family situations: mealtime, going to the park, driving in the car, etc. Enact several of these non-threatening situations, and let your child put words into the figures' mouths. When you get to bedtime, if your child is hesitant to talk, you can try speaking for the characters. If your child has gotten into the play, she will correct you if you give the characters motivations that are inaccurate from her perspective.
Another approach is to encourage your child to color or paint while she tells you about what she is creating. Be sure to allow her lots of time to open up and don't react negatively if she says something you don't want to hear.
The things you are most likely to find are: your child has night time fears, i.e. she is afraid of the dark, being alone, closet monsters, etc.; she is jealous of one parent or a sibling; she is afraid of losing your affection if she "grows up"; or some variation of one or more of these.
If your child is suffering from night time fears, give her tools that empower her to overcome her fears:
Give her a flashlight to play with (especially during the day in a darkened room) to help overcome fear of the dark.
Give her a spray bottle filled with "monster spray" so she can shoot the monsters if they come out.
Record a tape of her favorite stories and songs that she can turn on whenever she is feeling alone or afraid (it is best if the recording is of your voice).
Give her a stuffed animal as big as she is to sleep with.
Ask her for suggestions.
If the primary reason your child wants to sleep with you is night time fears, you should be able to switch her into her own bed as soon as she has the tools to cope with her fears.
If you discover that your child is jealous of one parent or a sibling, evaluate the situation and determine if she has reason to be jealous. If she has a younger sibling who is getting most of your attention during the day, she may feel the only time she "gets you" is at night. The best way you can help overcome her jealously is to pay special attention to her when she is not asking for it.
If your child reveals that she is afraid that she will lose your affection when she grows up, take stock of what you are communicating to her regarding growing up. You may inadvertently be sending her the message that you want her to stay a baby. If this is the case, consider how you can change her feelings by the way you communicate with her.
You will need to take some time for your child’s feelings to change before you can move her into her own bed. When you do, you may need to make the change in several stages. The first few nights, she might sleep on the floor beside your bed. The next move might be right outside your door, then into her own bed. The large stuffed animal or the tape recording of your voice may help ease the transition.
For most children, it takes many more hours of cumulative trauma than it does for an adult to cause aches or tingling (this can happen, though -- it's amazing how long a kid can stay glued to a computer game without a break).
