Make love more often
Sexually active individuals are generally more optimistic and positive for the simple reason that sex leads to the release of serotonin, a natural antidepressant. Give free rein to your emotions and let all that nervous tension ease away.
Laughter, like exercise, makes the body produce endorphins - the happiness hormones - and strengthens our immune system.
Get back to nature
Walks in nature can not only make us happier but also reduce our tendency to mull over and dwell on negative thoughts. If the sun is shining, the mood-lifting benefits will be even greater. Plus, wide open spaces can fill us with awe and wonder, which can help foster feelings of fulfillment.
A waft of vanilla
Smells and essences can affect our mood considerably. Vanilla has been the focus of several scientific studies and could be the most effective aroma for uplifting our state of mind.
Take a nap
Napping for 30 minutes per day has many health benefits, while also making us more efficient and creative.
Meditation focuses the mind and body on the present moment. This allows us to take control of the body's autopilot and curb wandering thoughts. With regular practice (ten minutes per day at first), you can learn to appease mind and body, and bring about a state of calm.
Eat foods rich in omega-3 fatty acids
Several studies have highlighted a link between omega-3 fatty acids and improved mood. Found in nuts – particularly walnuts – as well as seeds (chia, linseed), oily fish and certain oils (canola, walnut, linseed), these essential fatty acids are veritable mood lifters.
Neuroscientists and psychologists have found that altruism lowers levels of cortisol (the stress hormone), reducing inflammation, slowing heart rate, reducing blood pressure and pain.

Social interactions play an important role in improving quality of life, health and happiness levels.
