For side sleepers, keeping the spine, hips, and legs aligned is key to a good night’s rest—and a pain-free morning after. Everlasting Comfort’s memory foam knee pillow is ergonomically designed to fit between the knees or thighs to ensure proper alignment. One simple but game-changing feature is the removable strap, which you can fasten around one leg; this keeps the pillow in place even as you roll at night, meaning you don’t have to wake up to adjust it (or pick it up from your floor). Reviewers call the pillow “life-changing” and “the best knee pillow I’ve found.” Plus, it comes with two pairs of ear plugs.

According to the National Sleep Foundation, too much light in a room when you’re trying to snooze is a recipe for sleep disaster. These understated polyester curtains from ECLIPSE block 99 percent of light and reduce noise—plus, they’ll help you save on energy costs. "Our neighbor leaves their backyard light on all night with what I can only guess is the same kind of bulb they use on a train headlight. It shines across their yard, through ours, straight at our bedroom window," one Amazon reviewer who purchased the curtains in black wrote. "These drapes block the light completely."

Few things can disturb your slumber—and that of the ones you love—like loudly sawing logs. Philips’s Smartsleep Snoring Relief Band is designed for people who snore when they’re sleeping on their backs, and according to the company, 86 percent of people who used the band reported reduced snoring after a month. The device wraps around the torso and is equipped with a sensor that delivers vibrations if it detects you moving to sleep on your back; those vibrations stop when you roll onto your side. The next day, you can see how many hours you spent in bed, how many of those hours you spent on your back, and your response rate to the vibrations. The sensor has an algorithm that notes your response rate and tweaks the intensity of vibrations based on that. “This device works exactly as advertised,” one Amazon reviewer wrote. “I’d say it’s perfect.”

Why Does Altitude Affect Baking?

Even if you’re highly skilled in the kitchen, you might find yourself with a deflated cake or bone-dry brownies if you happen to be baking in Aspen, Colorado, for the first time. But why exactly does an oven at high altitude so often wreak havoc on whatever baked good is in it?

According to HuffPost, it all comes down to air pressure. The higher you are above sea level, the lower the air pressure is. This is mostly because there’s less air pressing down on that air from above, and it’s also farther from the gravitational forces on Earth’s surface. With less air pressure keeping liquid molecules in their liquid form, it takes less heat in order to vaporize them—in other words, boiling points are lower at higher altitudes.

“For every 500-foot increase in altitude, the boiling point of water drops by 0.9°F,” Dr. Craig F. Morris, director of the USDA ARS Western Wheat Quality Laboratory at Washington State University, told HuffPost.

Since liquids evaporate at lower temperatures, all the moisture that makes your signature chocolate cake so dense and delicious could disappear long before you’d normally take it out of the oven. To avoid this, you should bake certain goods at lower temperatures.

With less air pressure, gases expand faster, too—so anything that’s supposed to rise in the oven might end up collapsing before the inside is finished baking. Cutting down on leavening agents like yeast, baking powder, and baking soda can help prevent this. This also applies to bread dough left to rise before baking (otherwise known as proofing); its rapid expansion could negatively affect its flavor and texture, so you might need to adjust how much yeast you’re using.

If all the ways a recipe could go wrong at high altitudes—and all the experimentation needed to make sure it goes right—seem like a lot to keep track of, Betty Crocker has a handy chart with various types of baked goods and suggested modifications for them.
