2016 is a good year for Aries' health, and you can generally relax, as no major issues are to be expected. The year does see some ups and downs though, so be aware of them in order to be ready for stress and ailments. If you see any signs of any problems then be sure to seek advice and help.
When the Sun passes through Pisces in March, you could experience minor health problems, along with a knock to your confidence and will power. This can seem out of place to those around you... you will seem to be succeeding in your love and work life, while also experiencing inner turmoil. Try not to keep this turmoil to yourself – talk to close loved ones to gain fresh perspectives.
This knock to your inner self will only be brief, and your full happiness will return to you in mid April when the Sun moves into Aries, also boosted by Mercury to give a very powerful and positive influence to both physical and mental health.
At the end of July, when Mercury transits Leo, you might experience some instability to health and lifestyle. Financial stresses could contribute to this. Try to see the instability as an opportunity to make changes; start the diet that you always said you would, or the yoga class, and seek to make any lifestyle changes that you have been thinking about in the year so far.
Health will be strong for the first half of the year, with very few problems expected. More caution is required in the second half, especially during July and August, when stress could combine with minor physical ailments. Look after yourself, even when life is busy!
