Why the afternoon is harder

Almost everyone I speak to with Parkinson's describes the same shape to their day. The morning is manageable. By mid-afternoon everything is harder — walking, talking, the will to do anything at all. Then it lifts a little in the evening, or it doesn't.

It is one of the most common things people ask Marty about in the app, and one of the least discussed at appointments. So here is what is actually going on, and the handful of things that genuinely help.

Why the afternoon is different

Several things stack up at the same time, which is why it feels like a wall rather than a slope.

Medication wearing off. If you take levodopa, the effect of each dose fades before the next one lands. That gap is often called an "off" period, and afternoons are a common place for it to show up. This one belongs to your Parkinson's nurse or consultant, not to me — but it is worth knowing that it has a name and that timing can often be adjusted.

Fatigue that isn't ordinary tiredness. Parkinson's fatigue is not the same as being short of sleep. It is a symptom in its own right, it affects around half of people with Parkinson's, and it does not reliably improve with rest.

Blood sugar and hydration. Unglamorous, but real. A light breakfast and not much to drink by two o'clock will flatten anyone, and it flattens you further.

The accumulated cost of moving. Movement takes more effort with Parkinson's. By afternoon you have simply spent more than someone else would have.

Four things that reliably help

• Move in the morning, even briefly. People who do something early tend to report better afternoons. Ten minutes counts.
• Eat something with protein mid-morning. Steadier energy across the middle of the day.
• Drink more than you think you need. Thirst signals get less reliable, and mild dehydration reads exactly like fatigue.
• Rest before you need to, not after. Twenty minutes at one o'clock beats an hour of collapse at four.

If your afternoons have changed noticeably in the last few weeks, that is worth a conversation with your nurse rather than a workaround. Sudden change is information.

What Day2 does about it

The check-in on the home screen asks how you are moving this morning, and the session you get changes with your answer. On a "tired" day it gets shorter and gentler rather than disappearing — because doing something is what protects the rest of the day, and doing nothing is what a bad afternoon feeds on.

You can also ask Marty directly. He will not discuss your medication, and he will say so, but he will talk about everything around it.
