Eye Ergonomics – Proper Light Level For Reading and the Myth on Reading in Dim Light

January 28th, 2011


Proper light levels are essential for comfortable reading. But will reading in dim light ruin your eyes? The notion of this has been around for centuries, particularly since the time before electric light, where reading under dim light was common, or more like reading in candlelight during the night time.

Through much recent study, researchers have found that there is no conclusive evidence suggesting that reading in dim light will increase your chances of becoming nearsighted or farsighted. Some adverse effects of reading in dim light include headache, dizziness, and temporary blurred vision.The proper lighting level for comfortable reading is approximately 600 lux, or about the typical lighting level of a bright office. This can also be attained with a normal reading lamp or table lamp, placed about 2-3 feet away from the reader. Despite common myths, there is not enough evidence to determine whether nearsightedness is caused by anything outside of genetics. Some theories do exist, such as the common theory that doing “near work”, which includes reading up close for long periods of time, looking at objects from a short distance, or sitting too close to the TV, can lead to nearsightedness (myopia).

Other theories include eating too much bread or rice products as a child, and foods rich in carbohydrates. While these theories may have some merit, the evidence is simply not conclusive. So while proper light levels are essential for the best reading environment, there is no true indication that reading in dim light will ruin your eyes.

How to Avoid Seasonal Affective Disorder: SAD Season is on the Way

January 26th, 2011


That time of the year will soon be on us again.? Winter? Blahs may be called by any number of names, Seasonal Affective Disorder (SAD), Cabin Fever, and Post Holiday Blues. These are types of depression or the blues that occur during winter months.

SAD is the most serious. It is more then the blues but is actually a depressive disorder, although perhaps less severe. Symptoms of SAD (and any depression), include: feeling overwhelmed, frequent crying, and irritability (being easily annoyed). Sleep disturbance may be experienced as either sleeping too much, or having trouble sleeping. Appetite disturbances can also go either way that is, loosing your appetite and weight loss or increased appetite and weight gain. Post Holiday Blues is a phenomenon of being let down after all the excitement and activities of the season. For those of us who live in the north, the view from Jan 2 tends to be one of three long months of cold and gray. Cabin Fever usually refers to boredom and restlessness that occurs after a time of decreased activities and hum drum days and evenings in a limited space.
How to Avoid and Treat Winter Blahs

For SAD the most successful treatments are Light Therapy and or antidepressant medications.

Light therapy allows the brain to receive the light it needs to decrease the nighttime hormone of melatonin and increase serotonin and other neurotransmitters in the brain. This relieves depression, in the same way that antidepressants do. Light therapy can be had for free by going outside before 12 noon for 30 minutes every day, without sun glasses. This works even on cloudy days. To use artificial light you can buy a light box for about three hundred dollars, or you can make one. To make one you need to follow certain principles. You can use standard bulbs or fluorescent lights, full spectrum light is no longer considered necessary. The bulbs must produce about 10,000 lux of light. Lux is a measurement of the amount of light that gets to the surface of your eye. To make such a lamp with incandescent bulbs would take many bulbs and produce a lot of heat. One simple way to make a lamp is to mount eight 4 four foot florescent tubes in a shop light. This will supply 10,000 lux at about 3 feet. The lights should be covered with a diffuser and use the kind that doesn’t buzz! Remember, the light should be in front of you. Do not look directly at this or any bright light (including the sun) instead read or complete some other activity in the reflected light. Keep your eyes open. Thirty minutes in the am should help, but it needs to be done daily and before 12 noon. Relax under the light with your morning beverage and a newspaper.

In terms of antidepressants the SSRIs (selective serotonin uptake inhibitors) are the most common. These include medications such as Prozac, Zoloft, Paxil, Celexa and Lexapro. ? Some recent research with Fish Oil indicates that 3-4000 mg a day may work as well as prescription antidepressants. Fish oil is also good for many other areas of your health.

? Cabin fever and winter blahs usually can be easily managed with changes in routine.

For post holiday blues and to avoid cabin fever I suggest you have a gathering of family or friends around you. If you can only tolerate one or two that is ok. Have a comforting supper (chili or soup and bread) watch an upbeat movie or play a few games.
?Going outside is great if you can participate in an activity to keep you warm such as: walking, snowshoeing, skiing etc. Even short walks by you in the light can be helpful.? If you just can’t bring yourself to get outside, find a place inside with lots of light. It can be a spare room or basement I like my garage. Set up a table to do projects, crafts, refinish furniture, sewing, paint, draw, anything you like to do. Make sure this a place you can leave things lying around so you can go back to it any time you have a few minutes without having to set up. ? Even small changes in your routine can help. With a little planning and effort you can avoid the blues and even enjoy yourself this winter, and remember spring is not far off.

Don’t Let SAD Make You Sad

January 19th, 2011


Have you ever felt down during the winter months, when days are shorter and you’re inside more? You may have felt symptoms of SAD – seasonal affective disorder. SAD is a type of depression that hits most people as the seasons change, particularly into winter. For some SAD may be no more than a slight case of wintertime blues. But some people may find SAD to be severe and very debilitating – affecting their overall quality of life. Signs of SAD include changes to sleeping patters, craving carbohydrates, avoiding social interactions, and other symptoms of depression.

Because SAD can be severe, you should consult your doctor if you feel you are being exceptionally influenced by the change in season. If you’ve never experienced these winter time blues before, you would want to rule out any other underlying causes, like an underactive thyroid. Although a doctor may offer suggestions for treatment, including therapy or medication, there are many at home, holistic products and methods that may help you to naturally relieve symptoms of SAD or help to lessen its effects. Let’s take a look at each one.

Light Therapy
Many suspect that the primary cause of SAD is the decrease in light that occurs with the change in season. Although it may be cold out, it’s a good idea to spend some time outside each day, in the sunlight. Natural sunlight is the oldest and best method of relieving SAD. Another option is to get a light box or a lamp that reproduces the full spectrum that comes from sunlight. This stimulates the biochemical activity in your brain that helps to relieve a variety of symptoms.

A desk or floor lamp for light therapy are good options. You can sit under them for a couple of hours each day, working or reading, and get the exposure to full-spectrum light your body needs. Some people may find that a dawn-simulating alarm clock works well for them, too. These mimic a sunrise that’s timed to your wake up time, allowing you to get in some daylight even if you’re going to work or school in the dark.

There’s no set standard for light therapy as a treatment for SAD, although many recommend an intensity of 10,000 lux (units of light). You’ll want to check the light to see how close to the lamp you’ll have to be to get that benefit. You should also check to see if the lamp filters out the ultra-violet wavelengths that can lead to skin and eye damage (just like the real sun). If your lamp doesn’t, you’ll need to take necessary precautions when sitting under the lamp or look for one that has minimal UV. You may also want to experiment to find when and how long sitting under the lamp works for you. Most treatments recommend between one and a half and two hours per day to mimic the amount of natural sunlight you would get otherwise.

Aromatherapy
Aromatherapy can be beneficial for SAD-sufferers, as the essential oils can stimulate the body to produce more serotonin (which decreases with SAD onset), and provide soothing scents that can ease anxiety or uplift your mood. The wonderful smells can also add an element of freshness that’s often missing from rooms that are closed up for the winter.

Essential oils that work well for treating SAD are bergamot, lavender, frankincense, jasmine, and many oils from citrus plants (like lemon and neroli). Inhalation is the quickest way to deliver the benefits of aromatherapy. Their scents can be diffused through a room with a variety of diffusers, with or without candles. Reed diffusers are an easy, flame-less way to distribute the scent.

Adding scents to a bath can be a great way to experience aromatherapy as well. This hydrotherapy can also be beneficial for your skin. For an extra pick me up during the day, add a touch of oil to a small cloth or handkerchief you can pull out of your bag or pocket if you feel yourself getting a little down. Be sure to experiment with oils and different combinations to find the right scents for you. Above all, the scents should be pleasing to your nose.

Water Fountains
Water fountains have many benefits, and some of them may help to alleviate SAD when it strikes. The white noise of the running water provides an excellent soothing background noise that can help relieve anxiety or help you fall asleep. Water fountains can also add some humidity to the air inside a building – air that may dry out too much during winter heating, contributing to feelings of anxiousness and irritability. Fountains also counter the negative ions that collect indoors. They act as natural ionic air purifiers, helping you stay happy and healthy.

If you have an indoor water fountain, consider getting some indoor plants that will stay green through the winter season to set next to the water fountain. The plants can provide that extra bit of life that your room needs during winter, as well as making a great accent or centerpiece decoration. You can create a small garden to keep inside or have a mini-oasis to rest and refresh yourself by.

Balance Your Energies
Feng shui seeks to balance the energies of the world, bringing peace and harmony to your life and encouraging positive, beneficial energies. How well you’ve balanced the energies can have a very real effect on your moods. Feng shui incorporates many aspects of your life, from how you’ve arranged your furniture to what earth elements are represented in a room. Colors, textures, light, and many more things all give off energies in varying wavelengths that can either harm or benefit you. Ideally, feng shui can help you find the energies that are most beneficial to you.

Take a look at the arrangement of your house or office and the elements present. You may find that rearranging furniture or adding some elements with balancing energies in mind have a positive impact on your SAD and help you get through the winter months. Experiment a little to find your balance.

Exercise
One of the many symptoms of SAD is lethargy. You just don’t feel like doing anything and you spend your time sitting around. These feelings are due to a lack of serotonin in the brain, which can be naturally increased by physical activity. Exercise does more than just help you become fit; it can actually improve your mood and help you fight SAD. Exercise will also let you relax and take your mind off issues which may also stress you out. Fighting stress during the winter months is important. SAD can affect your ability to handle stress well.

If you also feel hopeless due to SAD, exercise can give you some goals and a great sense of accomplishment. Make exercising part of your daily and weekly routine. Joining a gym or taking classes will help you get out among people, reducing the isolation or avoidance of social activities that SAD produces. Exercise at least 30 minutes every day, and see how it help you.

Good Diet
Depression and SAD may be affected by your diet. SAD sufferers may find themselves with increased cravings for carbohydrates, including breads and sweets, than they normally would have. A lack of vitamins and minerals may also compound feelings of lethargy.

During the winter months, be sure to eat a balanced diet and get all the vitamins and minerals you need. Vitamin D deficiency, for example, can easily occur during winter if you’re not getting enough exposure to sunlight or full-spectrum artificial light. Fresh fruits and vegetables will provide your body with the good carbohydrates and natural sugars it needs to function – reducing your intake of unhealthy foods that can lead to weight gain during winter.

Have Fun!
SAD can have a real impact on your life, especially if it severely affects you every year. All of these suggestions, from light therapy to water fountains to exercise, can help you lessen or prevent the symptoms of SAD. If you find yourself retreating during these months, try to concentrate on the activities that are fun for you and help you defeat the negative thoughts and feelings. Being with friends and family, seeing a movie, or accomplishing a goal can go a long way. SAD doesn’t have to make you sad if you know what you’re facing and know how to get around it.
