If improving your sleeping habits made the list of your 2012 resolutions, then let's get to it! There are simple things you should and shouldn't be doing to get some quality shut-eye, but what about the person who sleeps to your right (or left)? Do you ever look at your partner as a roadblock to your sleeping success? If your significant other is interfering with your sleepy time, here are some helpful tips to get you back on track . . . no separate rooms required!

1. Some like it hot, some like it cold: If your partner likes to keep the heat cranked throughout the night, while you prefer to keep it at a lower temperature, use scientific evidence to win this battle. Like it or not, room temperature has a significant impact on sleep. To get proper, quality sleep, the body needs to reach an internal temperature of 65 to 72 degrees F. If he (or she) is still set on sweating it out, load up the blankets on their side of the bed and have them wear socks and a sweatshirt to bed.

When January rolls around, the festive fun has come to an end, and we resume our regular day-to-day routines . . . good times, right? This month can be especially difficult for some because the party is over, the temperatures are dropping, and the days are awfully short. If you're experiencing any symptoms that feel like major depression, you may be suffering from seasonal affective disorder (SAD). SAD is a type of depression that is cyclical and seasonal, meaning that it comes and goes at the same time every year. If you suffer from SAD, symptoms may include irritability, a drop in energy level, and possible weight gain. Various studies have shown that four to six percent of the population has been diagnosed with SAD at some point in their lives, while 10 to 12 percent have shown symptoms related to SAD. Fortunately, there are some easy remedies you can try at home to help get you through the next few months.

Don't just sit there! A little exercise goes a long way. A recent study led by the Population Health Research Institute at McMaster University in Canada found that just 30 minutes of exercise a week can lower the risk of a heart attack by about 30 percent. Fighting heart disease might not be your biggest concern, but the power of even a bit of physical activity is certainly motivating.

The study followed over 24,000 men and women of all ages, from 52 countries, and compared the work and exercise habits of the participants, 10,043 of which had already experienced a heart attack and the other 14,217 had no history of cardiovascular disease. The research found that any level of physical activity can lower the risk. The data, which made its way into the European Heart Journal this week, notes how the risk drops 13 percent for mild activity like yoga or slow walking, 24 percent for moderate activity like biking, and 30 percent for more strenuous physical activity like running. Surprisingly, the percentage didn't increase if the duration of physical activity went up — although 30 to 60 minutes of exercise a week was the sweet spot — which can be spread out over each day.

Now we all know how good exercise is for our overall health, which is why it's important to make sure you are exercising at least 60 minutes each week. And if you are looking to lose and maintain a certain weight, you'll want to engage in moderate exercise for five days a week. And by moderate, I mean "slightly breathless," making sure you get your heart rate up.

Perhaps signing up for yoga classes was one of your healthy New Year's resolutions? I have found that yoga can be practiced by anyone at any age and it does a body good . . . both inside and out. And contrary to popular belief, yoga is so much more than just stretching — it's a union of the mind, body, and spirit. Here are some tips I've learned after years of practice that should help you get started.

1. Inhale and exhale: Breathing is an integral part of yoga. It's easy to become so focused on achieving a particular pose that we tense up and forget to breathe. Proper breathing in yoga keeps you mindful of your practice and aware of each movement. Once connected to your breath, balance improves, muscles relax, and you're less prone to injury — hello, oxygen! The best way to breathe during yoga is deep down in your diaphragm (the large muscle right below your lungs). Slowly expand the lungs, pressing down the diaphragm, and causing your abdomen to expand as your lungs fill with air.
