Useful Tips

I learnt these tips from couple of magazines. Here is the summary.

Use the right batteries

Have you ever wondered why your digital camera quickly drain AA batteries? Here is the answer.

Traditional alkaline batteries work well in CD players and toys that don't require much power. But they sometimes provide only enough juice in digital cameras for a few dozen photos. Nickel oxyhydroxide and lithium pack more punch in each AA or AAA battery cell, and can more than double the number of pictures you can take with a digital camera.

More info:

Match the device with the right kind of battery. Brands such as Duracell, Energizer and Panasonic feature types of batteries that are designed for power-hungry gadgets such as portable-music players and digital cameras, providing a higher voltage and longer battery life. Rechargeable batteries work well in such devices and can save money in the long run. They provide less voltage and cost more initially, but they can be recharged hundreds of times depending on the battery's capacity.

How to Reduce the Screen Glare

Best option to reduce the screen glare is to Blink more and change some of the screen settings.
People who stare at light reflecting off a monitor tend to blink less. This lack of moisture can cause visual strain. The computer's settings also may have been changed by a previous user, meaning that the resolution and refresh rate need to be adjusted to reduce the amount of time it takes for your eyes to refocus.

The recommended screen resolution for a 17-inch monitor is 1,024 x 768 pixels and the average refresh rate is between 60 to 70 hertz. Resolution determines how many data are on the screen. The refresh rate controls the frequency of the screen's flickering. Both settings are under the display properties' settings tab.

Lowering the brightness and contrast levels of the screen can help to reduce the level of headache-inducing light and dims the tone of colors. A screen's brightness level should be in the upper 40s and the contrast in the lower 60s.

Fighting Off Jet Lag

After an overnight flight, American Airlines flight attendant Rosemary Wharton wears sunglasses on the ride from the airport so she can sleep when she gets to her hotel. Otherwise, bright light makes her too alert.

Once there, she usually naps for a few hours but makes sure not to sleep too long so she can adjust faster to the new time. Ms. Wharton stays hydrated before each flight so her body can recover quickly, but avoids drinking too much during the flight so she can sleep instead of going to the bathroom a lot.

If you use sleep medication, she recommends doing a tryout before your trip so you don't discover the side effects while over the North Atlantic.
