Raised my air pressure.
Decided to raise the pressure in my tyres and it made a big difference in the rolling resistance.. Did not think a 5 lb. change would make a noticable change so I jumped it 10 lbs, I would also have to mention that the temp. has changed from the high 80's -90's to the high 60's to the 70's. Have to raise myself off the seat for the obvious road shocks I can see and or know about so the ride has changed also but not enough to make me go back to the lower pressure. I had been running 65 front and rear and have raised it to 75. Tyres are Kenda Kourier, 700 x 35c. So, as I slowly reinstall my self on to my bike and relearn the obvious I continue to enjoy this sport more and more. I have been trying to keep in shape on my elliptical as it has been raining here and have had family obligations but the elliptical is not the same as the bike on hills. This my legs were very happy to explain to me yesterday.

For every 10 degrees F tire pressure changes by about 1 psi, so outside temperature change would have dropped your tire pressure by a few psi (provided you pump up the tires not on the street but inside your house which temperature remained more or less the same as in summer). So, by raising 10 psi, you actually raised pressure somewhere around 5-7 psi compared to summer.

Hey NC neighbor!
it much better to raise your air pressure then your blood pressure! Seriously, a lot of us play with PSI and ride characteristics. Do it yourself when you have the time and you will be dialed into your pressure sweet spot! Before you know it, the topics of tire size, tread and rotational weight will occupy your head.

I've always been one to pump my tires up to the max pressure listed on the sidewall. However, I had a tube assplode on me about a week ago and am now more accepting of less than max pressure.

Gone the other way. Was running my 26 1.5” at their rated 65 psi max. Dropped them bit by bit. Now running 50 and rolls just as well, Rides better and feels more sure footed. Less “boing-ey” on rough pavement.
