Feeling drained and can’t understand why? Sometimes you might be sleeping enough, exercising enough, eating healthily, and still feel tired. One possible reason could be your hormones.

Thyroid hormones

Your thyroid gland produces a range of hormones that help control your metabolism. If your thyroid is underactive, your metabolism starts slowing down, causing you to feel tired.


Having the right balance of oestrogen is very important for your energy levels. Bear in mind, these rise and change throughout your cycle.


Apart from triggering ovulation, it also promotes sleep which is why it’s sometimes called a ‘sleepy hormone’. High levels of progesterone could make you feel tired. 


Often called a “male” hormone, but it’s also really important for women’s health — you just produce it in much lower amounts. It’s needed to produce red blood cells — these help carry oxygen around your body, which is important for energy.


Cortisol plays a really important role in helping your body cope with stress. But, if you're stressed a lot and your cortisol levels are too high or too low, it can affect your sleep and energy levels.
