Let us tell you just how important sex is in a relationship by highlighting the healthy impacts it has on your well-being, and offer some additional reasons why your relationship can thrive from awesome sex.

1. Sex is emotionally fulfilling

There are few better feelings than being emotionally in tune with yourself and your partner(s). Sex releases oxytocin, sometimes called the “love” hormone, which improves emotional intimacy while mutually creating strong bonds. There’s a firm commitment and emotional connection that comes from sex that’s important in molding a healthy relationship. Some emotional benefits include:

2. Stress relief

Sex releases stress response hormones which contribute to lower stress levels and better management of everyday stressors. On top of that, you may feel like you’re in a better mood post intercourse, which is linked to feeling less stressed out. Ultimately, this may cause you to feel closer in your relationship.

4. Improved sleeping patterns

During orgasms, endorphins are released. Coupled with oxytocin, these hormones can act like a sedation that may put you to sleep more soundly. We could all use a good night’s sleep after some energetic sex.

5. Sex is physically rewarding

Another reason why sex is important in a relationship is that it offers physical fitness. Even if you’re not one for hitting the gym, sex is a great cardiovascular exercise that burns calories. Sweating IS sexy. Some other physical benefits of sex include:

6. Healing pain points

When getting intimate with your partner, and especially during those erotic massages, back pains and migraines may temporarily vanish. When those endorphins are released, calmness ensures. Trail off into some sexual healing… Marvin Gaye music optional, but highly recommended.

8. Lowering blood pressure

No kidding, frequent sex has been linked to having positive cardiac effects. Sex can actually dilate blood vessels, which increase the delivery of oxygen and nutrients inside your body, resulting in decreased blood pressure.
