How can I cope with tiredness without caffeine?

We understand how tiring pregnancy is for you and your body. Naturally, we are so used to reaching for a cup of coffee to get us through the exhaustion but you may be looking for alternatives to this so here are some tips on dealing with tiredness without turning to caffeine. Firstly, rest when you can. This can be trickier when you’re working and when you have other children to look after but get help and make time for yourself to rest. It’s key to listen to your body and rest when you’re feeling tired. Secondly, eat well and stay hydrated. It can be tempting to ‘eat for two’ but it’s only in the third trimester that you need an extra 300 calories. Eating a healthy and balanced diet throughout your pregnancy is energising and will help you to feel less tired. Finally, fresh air and exercise. Its important to rest but it’s equally important to keep your body moving. Getting out in the fresh air for a 20-30 minute walk will help you to feel energised.

How do I avoid caffeine without friends suspecting I'm pregnant?

So if you’re in the early stages of your pregnancy and choosing to keep it to yourself for now, you may be wondering how you’re going to cutback on caffeine without those around you guessing. Here are three ideas for how to go caffeine free without raising suspicions. Firstly, switch your drink completely. If the weather’s warm then opting for a fruit juice won’t seem unusual. Or try ordering a hot fruit tea and rave about the great flavour to keep others from suspecting. Secondly, you could tell your friends, colleagues, family that you’re going caffeine free for charity. Thirdly, avoid the coffee run and bring in your own decaffeinated drink in a reusable cup. You can distract colleagues by telling them it’s because you’re wanting to help save the planet with less waste.


Pregnancy is such an exciting time but it definitely comes with some negative sides too. Information on the negative impacts of caffeine can feel overwhelming.  And learning that you shouldn’t have coffee when you’re at your most exhausted is tricky. If youre used to regular caffeine fixes then cut down slowly and try swapping to decaffeinated alternatives. If you’re feeling more tired than before, get plenty of rest, eat well and stay hydrated before turning to a cup of coffee. And to avoid suspicions from those around you in the early days, get creative with your reasons for going caffeine free. Pregnancy can feel like it’s lasting forever but it won’t be long before your little one is here and you can enjoy your coffee once more.. Although you may have to get used to drinking it cold!
