I wanna start an active lifestyle again is it important to sweat to get benefits or is it ok to do activities that doesn't necessarily make you sweat?

It's OK not to sweat: How much you sweat does not necessarily correlate with how fit you are. Pilates and yoga, for example, can significantly contribute to fitness but typically don't result in a lot of sweating. Some cardio/aerobic exercise is helpful in your overall fitness plan, but brisk walking can provide that. Genetics and ambient temperature also play a huge role in how much a person sweats. Good wishes:)
