Many times, you wake up with severe headaches, whether it is because you slept in the wrong position or because you didn’t sleep enough. But if you are waking up with a headache everyday, then there may be some worrying underlying issue. Usually when you wake up, your brain is a little sensitive. According to a 2013 PLoS One study, the transition from your body sleeping to waking up means that there is a temporary reduction in your alertness, impaired performance and it is known as sleep inertia. Think of the shock you experience when someone switches the light on when you are trying to sleep. So, even small things, like a little tension in your neck or a slight dehydration, can feel like a big headache. Many people, especially those getting older, find they wake up with headaches more often. It's just a part of how our bodies work, but it can be really annoying. Knowing this can help you understand why it happens and what you can do about it.
