They buy separate sheets
If you share your bed with a partner, they may be the reason you're waking up groggy in the a.m. One thing Sleep to Live Institute director Robert Oexman, DO, tells his coupled-up patients to do is to buy individual sheets and blankets. "This allows each partner to move without disturbing the other, and it allows for different temperature needs," he says. Use the same fitted sheet, but then outfit the bed with two twin top sheets and blankets side-by-side. In the morning, cover the bed with a comforter for a more finished, cohesive look.
