Push-ups, crunches, gyms, personal trainers - people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?

Meditate.

That's the finding from a group of researchers at UCLA who used high-resolution magnetic resonance imaging (MRI) to scan the brains of people who meditate. In a study published in the journal NeuroImage and currently available online (by subscription), the researchers report that certain regions in the brains of long-term meditators were larger than in a similar control group.

As spring comes to a close and the sun melts kapha away, trying to keep pitta in balance quickly becomes an issue. With the summer season, skin will often react by becoming irritated with dryness or excessive oiliness, rashes, insect bites, and of course, sunburn. Ayurveda has solutions to each of these problems using all natural remedies.

In the quest for better health, many people turn to doctors, self-help books or herbal supplements. But they overlook a powerful weapon that could help them fight illness and depression, speed recovery, slow aging and prolong life: their friends.

Researchers are only now starting to pay attention to the importance of friendship and social networks in overall health. A 10-year Australian study found that older people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk for obesity among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could promote brain health as we age.
