Plus, mindfulness is inherently relational, and it affects how you behave and deal with people, says B Grace Bullock, PhD, a psychologist and author of Mindful Relationships: Seven Skills for Success . How you relate to your partner has a lot to do with how you relate to yourself, Dr. Bullock says. "If we can't control the role stress plays in our life, the effects of stress will bleed over into our relationships," Dr. Bullock says. And as much as I'd like to say that all my daily worries go away when I hit the sheets, that's just not true, and that's definitely not my partner's fault. That's why meditating before I know we're going to have sex helps me notice and accept that I'm stressed in the moment, and allows me to approach our time together without all of the baggage I've accumulated throughout the day.
