Could one daily habit become a lifestyle habit that affects your skin?

Recently, as my skin has become more sensitive, I've been wondering how small daily habits can make a big difference. It seems like the things we do without thinking during the day can actually become habits that affect our skin. Has anyone experienced this? I've noticed that small habits like late-night snacks or irregular sleep patterns can actually have a negative impact on my skin. Conversely, I've found that drinking plenty of water every day and stretching regularly have also become lifestyle habits that have had a positive impact on my skin, leading to positive changes. If you've experienced a lifestyle change that has had a positive impact on your skin, could you share what those changes have been?
