Experts know that pressure increases the chance of catching the cold. The reason? Your body’s helper—T cells, which are key to defending against viruses, become weakened when you’re worn out. Steal the secret: Do some problem-solving. First, take a hard look at the situation and really consider whether you can do anything to change things.
