13 things you should never do before bed

8. Smoking

Many people smoke to relax, but nicotine is a stimulant and can make insomnia worse, especially if you light up close to your bedtime. Nicotine withdrawal can also cause smokers to wake up earlier than they normally would in the morning.

9. Too much water

Staying hydrated is important, but it may not be the best strategy to drink a huge glass of water before bed or sleep with one water by your bed. This will only cause you to keep waking up to urinate.

Instead, make sure you’re drinking plenty of water throughout the day—and always be sure to use the toilet before you head to bed, even if you don’t feel like you have to.
