The first card is the reversed Five of Swords, which represents a distracted and negative mindset about health. The card indicates that there is a lack of awareness of the risks we can take due to an unhealthy lifestyle. This means that you are probably not considering enough the damage that an irregular lifestyle could cause.
The Eight of Swords suggests that you have a very good understanding that you need to take steps to improve your health. However, the card can also indicate that you are aware that one cannot immediately change a habitual lifestyle. You are therefore willing to face difficulties in finding healthier solutions but you also feel that there will be sacrifices to be made.
Wheel of Fortune suggests that you have already taken steps to improve your health. The card indicates that you are already ready to accept challenges and have taken concrete actions to change your lifestyle.
In conclusion, the cards show that you are aware that you need to take steps to maintain your health and are already taking concrete actions to achieve this goal. Therefore, the answer to the question is: Yes, you need to pay more attention to your lifestyle to maintain your health.
