The Lovers reversed indicate that there may be weaknesses in the situation, related to health. This may indicate that you will only need more rest if your health is not good. The card also suggests that your health can be affected by a lack of self-care. It's important to remember that it's not always necessary to have a long rest period to maintain good health; sometimes, a short rest is enough to regain balance.
The Eight of Cups upside down can be a sign that you need to change something in your life to improve your health. This card suggests that perhaps you need more rest as part of that change. This means that you may need to take some time for yourself to re-energise. There may also be other changes you could make to achieve good health, such as getting regular exercise or eating a balanced diet.
In conclusion, the two Tarot cards seem to show that you need more rest to improve your health, but only if your health is not good. You don't necessarily have to take a long time to rest, but you should take the necessary time for yourself in order to regain your energy and maybe even make some changes in your life. Therefore, the answer to the question is yes.
