Sunshine: You may be tempted to hide away in your bedroom when you're unhappy, but taking a stroll in natural daylight can really make the world of difference. Sunlight triggers the production of serotonin, with the condition seasonal affective disorder making sufferers feel extreme moods depending on the time of year. So, even if you're in the middle of winter right now, just wrap up warm and catch some rays before the sun sets at a ridiculously early hour.
Exercise: Working up a sweat can also increase levels of serotonin and dopamine, both of which help you focus on the rewards of exercising rather than the aches and tiredness that comes with it. You also release endorphins, feel-good hormones, when exercising, with previous study findings claiming just 20 minutes of moving can increase one's mood for up to 12 hours. If you're not a fitness fanatic, simply pick an activity which you enjoy to make the whole process more bearable (dancing counts!).
Sneak in some TLC: A little tender, love and care for the self is a great way to feel better; from a massage to a relaxing facial, choose whatever gratifies you most! It was previously found that a massage can relieve depression, stress and anxiety, with participants of a study seeing their levels of the stress hormone cortisol dropping by 53 per cent after a good rub done, as well as their serotonin levels increasing.
