What to Do the Night Before Scuba Diving

Get a good night’s sleep.

This is one of the most important things you can do to prepare for your dive. When you’re well-rested, you’ll be more alert and focused underwater. Aim for 7-8 hours of sleep the night before your dive.

Eat a healthy dinner.

Eating a healthy dinner will help you avoid getting sick underwater. Avoid foods that are high in fat or fiber, as these can cause stomach problems. Instead, opt for lean proteins, fruits, and vegetables.

Drink plenty of water.

Staying hydrated is important for overall health, but it’s especially important when you’re scuba diving. Dehydration can lead to fatigue, dizziness, and headaches. Drink plenty of water throughout the day, and especially in the hours leading up to your dive.

Avoid alcohol and caffeine.

Alcohol and caffeine can both dehydrate you and make you more susceptible to decompression sickness. Avoid these substances in the 24 hours leading up to your dive.

Gather your gear.

Make sure you have all of your scuba gear packed and ready to go the night before your dive. This will save you time and stress in the morning.

Review your dive plan.

Take some time to review your dive plan with your buddy. This will help you both be on the same page and avoid any surprises underwater.

Get excited!

Scuba diving is an amazing experience. Get excited about your dive and all the incredible things you’re going to see.
