Finding the right room temperature to sleep is the main key. 65 degrees fahrenheit is the optimal sleep temperature for most people. Whether a person has thyroid issues or not, following sleep hygiene is the best way for improving sleep quality. Sleep hygiene is a practice that an individual can follow everyday by sleeping at the same time at night and waking up at the same time in the morning. It is good to avoid using electronic devices before 1 hour of sleep and winding down the evening after work by doing some relaxation activities or exercises.
