Heart rate always 90

Answer 1

High resting heart rates may be due to activity, fever, stress, an overactive thyroid gland (hyperthyroidism), anemia, stimulants (caffeine, amphetamines, decongestants, Asthma medications, diet pills, and cigarettes), and various forms of Heart disease.

In general, people who do a lot of cardio exercise will have lower resting heart rates. Most likely, you haven't exercised enough during your life. You really should try to do more cardio exercise to see if that lowers your resting heart rate.

I've read several articles that suggest that people with low resting heart rates live longer. So even though you probably do not have an immediate cause for concern, in the long term you're probably going to be better off if you do more cardio exercise.

Good luck!!
