Today's smartphones mean you are never unreachable and people can call, send text messages, send instant messages, and email you. You can be on a beach lying in the sun and still be in touch with work contacts, friends and so on. A constant stream of emails, especial work messages, can ruin a holiday though, so before you set off you should set an automated vacation response in Gmail to tell everyone you are away and that you'll get back to them when you return. You'll have much more fun on your holiday without the distraction of work emails.
