A heavy or tired head, especially in the afternoon, as your head is a very sensitive indicator of thyroid hormone status.hyroid-related fatigue begins to appear when you cannot sustain energy long enough, especially when compared to a past level of fitness or ability.

Medical textbooks suggest that the normal respiratory rate for adults is only 12 breaths per minute at rest. Older textbooks often provide even smaller values (e.g., 8-10 breaths per minute).
On average, a person at rest takes about 16 breaths per minute. This means we breathe about 960 breaths an hour, 23,040 breaths a day, 8,409,600 a year. Unless we get a lot of exercise. The person who lives to 80 will take about 672,768,000 breaths in a lifetime. (This is based on a person's average respiration rate at rest. It does not take into account the increase in respiratory rate during exercise, or the fact that young children take about 44 breaths per minute.)
