【英语时差8,16】父亲也会得产后忧郁症？

 I know that new mothers sometimes experience postpartum depression. But can new dads get depressed¹ after having a baby,too? Intetesting question.And although it may surprise you, the answer is yes. Research shows that as many as one in four new dads experiences what’s known as paternal² postnatal depression. Hold on. Depression in new moms is often caused by hormonal³ changes during pregnancy⁴, right? Right. But new fathers don’t actually get pregnant, obviously. So Why The Depression? A few reasons. First, like new moms, new dads also go through hormonal changes. They often have higher estrogen and lower testosterone levels. Some biologists think its an evolutionary⁵ adaptation to curb⁶ a new father’s aggressiveness and keep him around to help care for the baby. New dads don’t get much sleep and have to deal with the stress of caring for an infant. Both factors could spur depression. Yep!Sleep deprivation⁷ is an especially tricky⁸ problem. Not getting enough sleep can mess up the balance of chemicals in the brain, raising the risk for depression. And if you already have underlying⁹ risk factors for depression, the chemical imbalance can be a strong trigger.
