Alcohol has major effect on the body. Sleep is one of the biggest effects for me. I wear a sports watch which I use for running but it also tracks sleep. For example I had a bottle of red wine last night, My watch pinged this morning to say I had poor sleep and that I should use today as a recovery day. Basically don't exercise. If I run the day after drinking My heart rate is a lot higher as well.
The problem is I really enjoy having a beer and socialising. So I try and get a balance, at the minute it's a pint for every mile I run
Yes and equally when your unwell, i've had (still going ) a high temperature and muscle aches since Tuesday my sleep scores have been terrible as i've been hot/cold all night.
