If you’re tired and lack sleep… it is going to impact your English learning. https://youtu.be/z9trFl-CsGI It’ll affect your ability to focus, stay motivated, and retain what you learn. And this goes with your other activities as well. Including how well you perform in English (i.e. when you’re actually using and speaking it). I’ve also had my fair share of extreme insomnia. I would just lie awake night after night and just not able to sleep. Sometimes I can even go an entire week with just 2-3 hours of sleep. And you know, whenever that happens, my ability to speak English clearly (even though English is my first language) just plummets. So, yes, sleep is extremely important. A great example of how sleep affects your English ability is with one of my coaching clients. She was really struggling with her English until she had a breakthrough. She started to build a healthy routine: exercising, changing dietary habits, and yes, sleeping. And that was completely transformative. Because just sorting out your issue of sleep will just make everything fall into place. Again, sleep is important. And it’s definitely something you need to consider doing more of if you want to speak better English. Anyway. If you’re looking to improve your English, start with the one-hour free training course that I made. You’ll learn the 5 changes my clients make to learn English faster and with less hassle. Hope that helps. Best, Dr Julian Northbrook
