What to Consider When You Buy a Light Box

Friday, February 10th, 2012

There are a few important considerations to make before you decided which light box will help you the most.

Light therapy for SAD comes in different light intensities. Light boxes differ in light intensity, size, shape and features.  These are the things you should consider to find the safest and most suitable light box for your needs:

  • Light Intensity – Look for a light box that provides the right intensity of light when you’re a comfortable distance away. For example, it may be effective to use a light box that produces 10,000 lux (a measurement of light intensity) at 24 inches from you for 30 minutes each morning.
  • Does it have Blue Light? Blue light can cause damage to your eyes so avoid a light box that uses blue light, especially if you have a history of eye issues.
  • Does it have no UV light? – There are certain light therapy boxes for SAD that use broad spectrum lights that don’t even emit UV rays. If you’re not sure, contact the manufacturer for safety information
  • Is the light box made for SAD and depression? Make sure you are not buying a light box designed for skin orders for example (red or blue light). You should look for a light box specifically for SAD or depression for it to be safe and effective for you.
  • Style and features – Make sure the size of light box fits your needs. Keep in mind; most light boxes need to be positioned within 2 feet of you.
  • Cost – The prices vary, but some health insurance companies cover some of the cost of light therapy for SAD, but you will of course have to get a prescription from your doctor.

Melatonin and Sleep

Wednesday, January 18th, 2012
Here is a great article from the National Sleep Foundation about Melatonin and sleep. You can read the full article HERE.

Melatonin and Sleep

The pattern of waking during the day when it is light and sleeping at night when it is dark is a natural part of human life. Only recently have scientists begun to understand the alternating cycle of sleep and waking, and how it is related to daylight and darkness.

A key factor in how human sleep is regulated is exposure to light or to darkness. Exposure to light stimulates a nerve pathway from the retina in the eye to an area in the brain called the hypothala-mus. There, a special center called the supra-chiasmatic nucleus (SCN) initiates signals to other parts of the brain that control hormones, body temperature and other functions that play a role in making us feel sleepy or wide awake.

The SCN works like a clock that sets off a regulated pattern of activities that affect the entire body. Once exposed to the first light each day, the clock in the SCN begins performing functions like raising body temperature and releasing stimulating hormones like cortisol. The SCN also delays the release of other hormones like melatonin, which is associated with sleep onset, until many hours later when darkness arrives.

Because melatonin is a hormone that is part of the human sleep-wake cycle, many people think that by taking more of it as a pill, it will help them to fall asleep faster or stay asleep longer. This brochure will provide more information about melatonin and help you decide whether this is something you should use.

Overall, the National Sleep Foundation (NSF) recommends that if you feel a sleep problem is serious enough to treat, then you should consult your physician first to make sure you understand the cause of your sleep problem and treat it appropriately.

Melatonin is a natural hormone made by your body’s pineal (pih-knee-uhl) gland. This is a pea-sized gland located just above the middle of the brain. During the day the pineal is inactive. When the sun goes down and darkness occurs, the pineal is “turned on” by the SCN and begins to actively produce melatonin, which is released into the blood. Usually, this occurs around 9 pm. As a result, melatonin levels in the blood rise sharply and you begin to feel less alert. Sleep becomes more inviting. Melatonin levels in the blood stay elevated for about 12 hours – all through the night – before the light of a new day when they fall back to low daytime levels by about 9 am. Daytime levels of melatonin are barely detectable.

Besides adjusting the timing of the clock, bright light has another effect. It directly inhibits the release of melatonin. That is why melatonin is sometimes called the “Dracula of hormones” – it only comes out in the dark. Even if the pineal gland is switched “on” by the clock, it will not produce melatonin unless the person is in a dimly lit environment. In addition to sunlight, artificial indoor lighting can be bright enough to prevent the release of melatonin.

The amount of melatonin released at night varies among individuals, but it is somewhat related to age. Children on average secrete more melatonin than adults, which decreases further with age. However, research has shown that older people with sleep problems do not always have lower melatonin levels than people who experience normal sleep.

Ways to Boost Your Metabolism

Thursday, January 5th, 2012

It’s already evident that when cold weather comes along, hibernation mode soon follows. A recent Gallup poll confirmed that Americans steadily eat worse and exercise less during the fall and winter months – and even more so in 2011 than last. In November, only 49.8 percent of adults reported exercising for at least 30 minutes three or more times a week, compared with 50.5 percent last year. Only 54.7 percent of Americans reported eating five or more servings of fruits and veggies at least 4 days a week in November, down from a high of 57.8 percent in July and the lowest recorded for that month in any prior year, including in November 2008 during the financial crisis.

Given these trends, the seasonal “fat creep” seems inevitable – but it doesn’t have to be. You can fight back with these simple steps to rev up your metabolism. Read on for 10 ways to stoke up calorie burn in January and beyond.

Warm Up Your Breakfast

If cold cereal seems less than inspiring on chilly mornings, start your day with a steamy bowl of oatmeal topped with flaxseed instead, recommends Erin Palinski, RD. Eating breakfast, in general, has been shown to boost your metabolism by as much as 10 percent, and oatmeal, in particular, can rev calorie-burning capabilities. One cup of oatmeal contains 13 to 16 percent of your daily recommended intake of fiber, and your body burns up to 30 percent more calories digesting fiber than it does other nutrients because roughage takes such a long time to break down.

Make Cross Training More Fun

Sometimes the hardest thing is to stick to your workout routine during the winter, and one of the most important things to keep your metabolism revving is consistent activity. To fight off winter sloth, take advantage of seasonal activities. “Try dropping one gym workout a week and add a winter sport – ice skating, snowshoeing or skiing. It’s great to mix it up and you’ll get back to the gym with a real spring in your step!” says Gunnar Peterson, a celebrity trainer and spokesperson for Under Armour.

Drink Up to Fight Dryness

Sure, it’s easy to remember to rehydrate when you’re sweating buckets, but it’s equally important – if not more – to get your eight cups of water a day in winter because the dry air can increase your likelihood of dehydration, says Jim White, RD, a spokesperson for the Academy of Nutrition and Dietetics and owner of Jim White Fitness and Nutrition Studios in Virginia Beach, Va. Being mildly dehydrated can slow your metabolism by 2 to 3 percent, according to researchers from the University of Utah. Why? Experts speculate that the rate at which your cells metabolize fat has to do with their size, and when they shrink from dehydration they become less efficient.

Hold Off On the Booze

Keep in mind that alcohol not only adds calories to your diet, but also slows down your body’s fat-burning capabilities. An American Journal of Clinical Nutrition study found that drinking can slow your metabolism by as much as 73 percent. “Plus, most people don’t make the best decisions about food when drinking and tend to skip their workout the next day,” says White, who advises sticking to a “two-glass class” rule.

Try Rye

Loaded with metabolism-boosting fiber, hearty rye bread might be better to eat than wheat when it comes to losing weight. Swedish researchers found that people who had rye bread for breakfast were less hungry later in the day than those who ate wheat bread. While fiber fills you up without weighing you down, researchers believe that part of the satiety of rye bread might be more mental than physical. The darker the bread, the fuller people expect to feel.

Pop a Fish Oil Pill

By now, the mood-boosting power of omega-3s in fish oil is a well-known way to help fight seasonal affective disorder but it may also give your metabolism a lift, says Palinski. Australian researchers found that in combination with exercise, fish oil can increase the activity of enzymes responsible for fat oxidation.

Sign Up for Spin Class

If the cold, dark days have cooled off your motivation to exercise, think about taking an indoor spin class. You can burn about 500 calories per 40-minute sweat session, and your body will continue to burn calories after class is over, thanks to the metabolism-boosting powers of intervals, which you perform when simulating hill climbs.

Dig in to Potatoes, Grains and Beans

Eating a diet rich in resistant starch – a type of dietary fiber found in many carbohydrate-rich foods such as potatoes, grains and beans – can help rev fat burning and reduce overall hunger. Your body doesn’t digest or absorb this supernutrient, so it does not contribute to body fat. Instead it’s fermented when it reaches the large intestine, which creates beneficial fatty acids that block the body’s ability to burn carbohydrates. One study found that replacing just 5.4 percent of total carbohydrate intake with resistant starch created a 20 to 30 percent increase in fat burning after a meal. Just be sure to avoid fatty extras like butter and cheese when preparing and watch your portions.

Have You Been Feeling SAD This Winter?

Tuesday, January 3rd, 2012

Seasonal affective disorder (SAD) is a form of depression that affects many people, especially women, during the winter months when there is less natural sunlight. For most with SAD, the depression generally lifts during spring and summer. More importantly, SAD is treatable with a variety of methods, including light therapy, psychotherapy, or medication.

A more recent study has found a connection between this type of depression and the pineal gland. The pineal gland is located in the middle of the brain. It responds to darkness by secreting melatonin. Melatonin is a hormone that helps regulate a person’s sleep and wake cycles. This hormone helps to reset your inner clock and manage your body’s daily rhythms.

The reduced daylight that comes during the winter season in the northeast seems to affect when your pineal gland releases melatonin. The time period between when your body releases melatonin can become longer or shorter than it is during the spring and summer months. As a result, your body’s rhythms become upset and misaligned. These daily rhythm mismatches may be a cause of SAD. For some, melatonin supplements at the right time of day have offered relief from the symptoms of SAD.

For others, antidepressants, light therapy, speaking with a counselor, or a combination of two or more of these treatments successfully relieves symptoms. Light therapy consists of regularly exposing yourself to a light source that emits wavelengths of light similar to that produced by the sun. The light is administered regularly for a certain amount of time and, in some cases, at a specific time of day. Light therapy also helps to reset your body’s essential rhythms, including your wake/sleep cycle.

People with SAD experience emotional and physical symptoms that may include: feeling sad, anxious or empty for most of the day, for more than two weeks; having no interest in activities or hobbies used to be enjoyable; feeling more irritable and getting frustrated more easily; feeling guilty, worthless, helpless, or overwhelmed often; having no energy most of the time; eating or sleeping more or less than usual; having trouble concentrating or making decisions; or having thought of suicide or hurting others.

If you are experiencing three or more of these symptoms or if your sad mood is interfering with your daily activities, you could be suffering from SAD or depression. Make an appointment to see your health care provider and share your symptoms.  SAD and depression are illnesses just like the flu or a sore throat. Getting help can make a big difference in how you feel both physically and emotionally. You’ll experience a better sense of well-being, no matter what the season.
