What are the best supplements to take for sleep?

Sources:

For better sleep, the recommends several supplements:

  • Magnesium: Both Magnesium Threonate and Bisglycinate are suggested for their ability to help with the transition to sleep and sleep depth, yet without causing drowsiness that prevents functioning if needed during the night. They're also associated with cognitive support and neuroprotection, although more data is needed on those benefits (1).
  • Apigenin: Derived from chamomile, this supplement can reduce anxiety which is helpful before sleep, for turning off excessive thinking necessary for falling asleep (1).
  • Theanine: Good for reducing anxiety and aiding in sleep, although it might cause vivid dreams or waking up during the night for some, so its use depends on individual experience (2).
  • Myo-inositol: Particularly helpful for shortening the time it takes to fall back asleep if waking up in the middle of the night, with additional mood-related benefits (3).

    Sleep Supplements

    Andrew discusses the effectiveness of magnesium and apigenin supplements in aiding sleep. He suggests trying them separately or together to determine which works best for the individual.

The quantity and combination of these supplements may vary based on individual experiences and sleep issues, such as falling asleep versus staying asleep. advises deploying them systematically and consulting healthcare professionals before starting any supplement regimen. It's also suggested to occasionally skip taking them to check for dependency issues, which appear to be minimal in the case of the recommended supplements (5, 6).

For enhancing overall sleep quality, lifestyle behaviors such as managing caffeine intake and meal timing are also crucial (3).

When considering the purchase of a cold plunge, it's essential to ensure that it aligns with your goals, be it for recovery, mental resilience, or inducing thermogenesis. Also, be sure to buy from a reputable source, and follow all guidelines for safe use as outlined by the manufacturer.

Do I need one?

Sources:

Whether or not you need a cold plunge depends on your individual goals and preferences. There are various potential benefits to deliberate cold exposure, but also some nuances to consider based on what has shared:

  • Recovery: Cold can be leveraged as a powerful tool for recovery after workouts, but to maximize return to baseline levels of temperature, cooling specific areas like the palms, the bottoms of the feet, or the face could be more effective than full-body immersion in cold water. Full cold immersion right after strength training could potentially inhibit muscular hypertrophy (1).

  • Mood Enhancement and Stress Management: Cold exposure could lead to enhanced mood, alertness, and a better ability to manage stress due to increases in catecholamines like dopamine. Managing breathing during initial stress from cold exposure can also help with stress resilience (2, 3).

    Cold for Recovery

    Andrew explains that using cold therapy for recovery can be effective but it's important to cool the body back to its resting temperature, and that just simply cooling the entire body by jumping into an ice bath or a cold shower is not the best way to go. He suggests relying on one of three glaborous skin portals of the palms, the bottoms of the feet or the face.

  • Dopamine and Performance: Engaging in deliberate cold exposure, especially early in the day, could increase dopamine levels for long periods of time. However, this should not be done immediately after strength or hypertrophy workouts, as it may suppress the adaptation from such training. Temperatures ranging from about 37°F to 55°F for short durations or slightly warmer temperatures for longer durations can significantly increase baseline levels of dopamine (4).

  • Brown Fat Activation and Metabolism: Cold showers or full immersion can activate brown fat, which can increase metabolism. There are fewer studies on cold showers, and more research is needed to understand their precise effects on brown fat activation compared to full immersion (::cite[chunk_82371]).

These benefits are not exhaustive, and the need for a cold plunge is ultimately subjective. If these benefits align with your goals, a cold plunge might be a valuable addition to your routine. It is also important to consider any potential risks and to approach cold exposure with caution, especially if you have certain health conditions. Always consult with a healthcare provider before beginning any new health-related practice.
