A Doctor explains that inter-personal touch not only raises oxytocin, but reduces cardiovascular stress and improves the immune system. Rather than just a hand-shake, go in for the hug.

You can strengthen work and personal relationships through a simple birthday or anniversary gift.

Aromatherapists, particularly the smell of vanilla and lavender has been linked with the production of endorphins. Studies have shown that dark chocolate and spicy foods will cause your brain to release endorphins. Keep some scented oils and dark chocolate at your desk for a quick endorphin boost.

Serotonin flows when you feel significant or important. Reflecting on your past achievements allows your brain to re-live the experience. Your brain has trouble telling the difference between what is real and what is imagined, so it produces serotonin in both cases. Gratitude practices are popular for this reason, they are reminders -- mental pictures -- of all the good things you’ve experienced. If you need a serotonin boost during a stressful day, take a few moments to reflect on your past achievements and victories.

The release of oxytocin creates trust and strengthens relationships. It’s released by men and women during intimacy and orgasm and by mothers during childbirth and breastfeeding.

Break big goals down into little pieces. Rather than only allowing your brain to celebrate when you’ve hit the big finish line, you can create a series of little finish-lines for frequent dopamine release.

And avoid the dopamine hangover -- when you slump after a massive high.

As a leader, you can boost your company morale by reflecting on past achivements during team meetings. Another way to boost your serotonin levels is to have lunch or coffee outside and expose yourself to the sun for 20 minutes; your skin absorbs UV rays which promotes Vitamin-D and serotonin production. Although too much ultraviolet light isn’t good, some daily exposure is healthy for boosting your serotonin levels.

Dopamine motivates you to take action toward your goals and gives you a momentum of reinforcing pleasure when achieving them. Procrastination, self-doubt, and lack of enthusiasm are linked with low levels of dopamine.
