VO2 Max is the most accuratemeasure of cardio-respiratory fitness. It measures the maximum amount of oxygen that the body can use in one minute per kilogram of body weight (mL/kg/min). During exercise, the heart rate responds by increasing, as does the delivery of oxygen to the body.

It could be that your house is too cold, or there is something in the air that makes you sick.
Hope that helps :)
The most maintained home fitness equipment is the treadmills. Once or twice a
week, clean the motor cover and unprotected areas of the deck and its stop
button operation. Use vacuum to clean the motor electronic compartment and
underneath any treadmill that’s on the carpet once a month, this would help
keep treadmill machines away from carpet fiber. For treadmills with
programmed wax oil frameworks, check and clean the wax spout every month.
Try not to utilize cleaning solution to wipe the belt; this will disable
the lubrication framework. Each a few months, check the belt tension and
tracking and investigate the equipment (stray pieces), belt and deck for
wear each three to a half year.
