10 Things You Should Never Do After Scuba Diving

When you dive with Circle Divers in the Red Sea, safety doesn’t stop when you surface. Whether you're enjoying boat diving in Sharm El Sheikh, shore diving in Dahab, or exploring sites like Ras Mohammed National Park, what you do after your dive is just as important as what you do underwater.

This guide explains the 10 things you should never do straight after scuba diving, helping you protect your health, recovery, and future dives.

 

Why Post-Dive Safety Matters in the Red Sea

Diving in Egypt offers world-class conditions — clear water, vibrant reefs, wrecks, and abundant marine life. But like all diving environments, proper surface discipline reduces the risk of decompression stress and improves recovery.

At Circle Divers, our priorities are quality diving, diver safety, and hospitality. These post-dive rules support responsible diving practices for both recreational and technical divers.

 

1. Do Not Fly Too Soon After Diving

One of the most important rules in scuba diving is avoiding immediate air travel. Flying reduces ambient pressure, which can increase the risk of decompression sickness (DCS).

If you're diving in:

·        Sharm El Sheikh

·        Dahab

·        Or joining a Red Sea mini safari

Always plan sufficient surface intervals before heading to the airport.

The following DAN guidelines apply to air dives followed by flights at cabin altitudes of 2,000 to 8,000 feet (610 to 2,438 meters) for divers who do not have symptoms of decompression sickness (DCS):

·        For a single no-decompression dive, wait at least 12 hours before flying

·        For multiple dives per day or multiple days of diving, wait at least 18 hours before flying

·        For dives requiring decompression stops, wait at least 24 hours before flying

To err on the side of safety, many divers plan a 24-hour surface interval before flying after any type of diving

 

2. Avoid Hot Tubs, Saunas, or Steam Rooms

Heat increases blood circulation, which can affect how residual nitrogen behaves in your body. Immediately after diving, avoid:

·        Hot baths

·        Saunas

·        Steam rooms

·        Heated spas

Cool, calm recovery is best.

 

3. Freediving and Snorkelling

If you resurface desperate to return to the depths (say, in an impromptu freediving session), think again. The nitrogen that builds up in your body during scuba diving needs time to be released. However, the ascents and descents characteristic of freediving cause pressure changes that can interfere with this process, leading to more nitrogen bubbles forming in your body. Because of this, your risk of decompression sickness (DCS) increases if you freedive after scuba diving. While snorkelling, especially at shallow depths, is nowhere near as risky, it's always best to allocate a 24-hour surface interval - just in case.

 

4. Don’t Drink Excessive Alcohol After Diving

Although many of us look forward to the deco beer after a day’s diving, always drink in moderation.

Alcohol increases dehydration and can mask early symptoms of decompression illness. After diving with Circle Divers, we recommend:

·        Rehydrating first

·        Eating properly

·        Avoiding alcohol until fully recovered

It’s best not to mix alcohol and scuba diving trips. But if you want to drink alcohol after diving, wait a few hours and hydrate prior.

4. Mountain Climbing or Driving

It may surprise you to discover that driving or hiking to the top of a 10,000-foot (3,048-meter) mountain puts you at the same risk for decompression sickness (DCS) as flying in an airplane. Cabin pressure in an average commercial jet is equivalent to being at 6,000 to 8,000 feet (1,800 to 2,400 meters) above sea level

In the same way, if your journey home involves driving to altitude after diving, for example the journey back to Cairo by road, you should allow a sufficient surface interval to reduce the risk of decompression sickness (ideally 24 hours)—or choose an alternative route.

 

 5. Avoid Intense Exercise Immediately After Diving

Heavy workouts, running, or high-intensity training right after diving may increase decompression stress.

Instead:

·        Rest

·        Light walking is fine

·        Avoid strenuous physical activity until your surface interval is complete

This applies to recreational divers and technical divers alike.

 

6. Don’t Go to High Altitude Without Planning

Driving into mountainous areas or hiking can reduce ambient pressure, similar to flying. If you plan on going to St Catherine’s Monastery during your stay, always leave 24 hours after scuba diving before embarking on the climb.

If you're diving in Egypt and planning travel afterward, always factor in:

·        Elevation changes

·        Travel time

·        Surface intervals

This is especially relevant for multi-day dive holidays.

 

7. Never Ignore Unusual Symptoms

After diving, seek medical advice if you experience:

·        Joint pain

·        Tingling or numbness

·        Extreme fatigue

·        Dizziness

·        Shortness of breath

·        Skin changes

Early action is essential. Safety is always the priority at Circle Divers.

 

8. Don’t Skip Proper Surface Intervals

Surface intervals are part of your dive plan. Whether you're:

·        Doing shore dives in Dahab

·        Enjoying boat diving in Sharm El Sheikh

·        Or participating in advanced training

Use your surface time wisely:

·        Hydrate

·        Rest

·        Review your next dive

·        Monitor how you feel

Conservative planning improves long-term diving enjoyment.

 

9. Deep Tissue Massage

What? No massage? Relax and breathe. Here’s the good news – according to the Divers Alert Network (DAN): “Massage has not been confidently associated with…cases of DCS”. Experts caution against deep tissue massage, but a gentle relaxation massage is probably fine. The two main concerns with deep tissue massage are:

·        Increased blood flow might lead to bubble formation

·        Muscle soreness which can lead to misdiagnosis (or delayed diagnosis) of decompression sickness (DCS)

The advice is to stay away from deep tissue massages for at least 12 hours after scuba diving.

10. Don’t Neglect Your Equipment Care

Proper gear maintenance protects your safety and investment.

After diving with Circle Divers:

·        Rinse equipment in fresh water

·        Clean regulators and BCDs properly

·        Avoid direct sunlight during drying

·        Store gear correctly

Well-maintained equipment performs better — and lasts longer.

 

Bonus: Respect Your Body

Every diver is different. Factors such as:

·        Age

·        Fitness

·        Number of dives

·        Depth and duration

·        Temperature

·        Hydration

All influence recovery. Listening to your body is one of the best safety tools you have.

What Can I Do After Scuba Diving?

So, let's finish with a few things you can do. Post-dive, it's best to drink lots of water - or whatever hydrating liquid takes your fancy - lounge about in the shade, read a book by the pool (supposing said pool is not atop a cliff), and generally take it easy. You are meant to be on holiday after all!

Enjoy a nice meal with your diving companions - Feeding your body the right nutrients is also key when it comes to caring for yourself after diving. Some foods with high protein aid the fast recovery of muscles, and some complex carbohydrates can help replenish the energy required. Omega-3-rich foods, such as kidney beans or walnuts, can help reduce inflammation. It is best to stay away from big, heavy, greasy meals, because they can lead to discomfort, especially if you plan on scuba diving more the same day.

 

Conclusion

What you do after scuba diving is just as important as the dive itself. Avoid flying too soon, stay hydrated, skip alcohol, and respect surface intervals.

Safe habits protect your health — and allow you to enjoy more unforgettable dives with Circle Divers in the Red Sea.

Dive safe. Recover smart. Keep exploring.
